Yuba Bikes - Mundo

Yuba Bikes specializes in cargo bicycles, bikes made to haul a variety of loads from groceries to restaurant deliveries to even families. We remember seeing Yuba Bikes at the Sea Otter Classic many years ago, they have been around since 2006. At the Interbike Preview show, we had a chance to chat with Ben Sarrazin, Founder of Yuba Bikes as he showed us 3 new bikes from his line.

Yuba – Mundo

First up is the Mundo. The Mundo is Yuba’s most popular model and has various configurations with the many add-ons that they offer to help no matter what kind of load you are carrying. We asked Sarrazin how has the advent of electric bikes effected the cargo bike world and Ben responds by saying, “We are definitely selling more and more electric versions of our cargo bikes. From last year to this year, we went from selling about 20% of our bikes as electric to 40% for this year.”

In talking with Sarrazin, it is obvious that using the bicycle as the main mode of transportation is something that he is passionate about. He talks about using the bike to drop off the kids at school in the morning, bike to the office, and then pick up groceries on the way home. Given his European upbringing, his outlook makes sense and getting more people out of cars and on bikes is definitely a worthy cause.

The base model Mundo has an MSRP of $1299 and the electric version with BionX hub motor has an MSRP of $3199. Both are available now through your local Yuba Bicycles dealer or via the Yuba Bikes website direct.

Yuba Bikes - Boda Boda

Yuba – Boda Boda

Next up, Sarrazin showed us the Boda Boda. Our first question was, “what the heck is a Boda Boda?” It is named after the motorcycle taxis in Africa that take passengers to the other side of town or are used as delivery vehicles for restaurant owners that need 5 kilos of rice picked up from the market. The Yuba version Boda Boda is a lighter, more compact cargo bike without the superlong wheelbase. It has front basket options, pannier options, handles for passengers and other options as well. It has a step-thru frame for women riders or shorter riders.

The Boda Boda has an MSRP of $999 in either traditional or step-thru frame and the electric version (called the elBoda Boda ) has an MSRP of $2899. Both are available now through your local Yuba Bicycles dealer or via the Yuba Bikes website direct.

Yuba – Flip Flop

Brand new from Yuba is probably the world’s first kid’s cargo balance bike, called the Flip Flop. For the kids of parents who have cargo bike, the Flip Flop gives the kids a chance to carry their own cargo like their toys or snacks, by providing a rear rack for a small pannier style pack.

But why is it called the Flip Flop? The biggest feature of this little bike is that the entire frame can be turned upside down to create a bigger bike, thus extending the usable life of the bike. Yuba says the bike can be used by kids from 1 and a half to 6 years of age. As any parent knows, the fact that kids outgrow things so fast (toys, clothes, bikes) building something that can change and grow along with them is a pretty cool thing. By flipping the bike over, the seat is higher and the geometry also gets raked out just a bit. Also, the handlebars are adjustable and can be raised and lowered (as well as the saddle) and the rear rack will still fit. If you noticed the two holes on each side towards the front of the frame, that is made to hold a small, soft pack in front for small items.

The Flip Flop is available in 3 colors (lime, raspberry, aqua) and has an MSRP of $159.99 and will be available November 2014.

Moab BLM bans electric bikes on non-motorized trails

Captain Ahab Moab

Under new rules, e-bikes aren’t allowed on Moab’s mountain bike-specific trails like Captain Ahab.

In a move that could prove to be a bellwether for other trail systems across the US, the Moab Field Office of the Bureau of Land Management (BLM) has posted updated guidelines to their web page putting electric-powered bicycles in the same category as gas-powered vehicles, effectively banning them from numerous trails in and around the Utah mountain bike mecca.

While motor assisted bicycles are now not allowed on mountain bike trails, they are permitted on any motorized route open to motorcycles and off-road vehicles. This includes portions of classic trails like Porcupine Rim, where e-bikes are permitted on the “Jeep road” sections, but not the singletrack.

While significant, e-bikes will still have access to hundreds of miles of trails and unpaved roads in the area.

The BLM has published an updated PDF map showing the following trails it lists as “Mountain Bike Trails”:

  • Amasa Back Area
  • Bartlett/Jedi Slickrock
  • Gemini Bridges/Mag 7 Area
  • Klondike Bluffs Area
  • Klonzo Trails
  • Kokopelli Trail
  • Lower Monitor and Merrimac
  • Moab Brands (Bar M)
  • Pipe Dream
  • Porcupine Rim
The Moab Bureau of Land Management has classified e-mountain bikes as motorized, limiting their legal access in the area.

In other Moab news, a former unsanctioned trail on the bluffs north of town known as the “Blue Dot Trail” has been formally added to the area’s trail inventory and is now called the Gold Bar Rim Singletrack. Known for it’s difficulty and trials-like demeanor, local trail builders have added “helper lines” to make the route more rideable while maintaining the original’s techy personality. Additionally, the blue dots have been replaced with yellow lines and additional signage is being installed.

Big Cat E-Bykes men's electric Fat Cat all terrain mountain bike.

Big Cat E-Bykes men’s electric Fat Cat all terrain mountain bike (click to enlarge).

It was right at the point where my legs were about to seize, my lungs were expired, and my heart rate was near boiling that a slightly overweight middle-aged man casually rolled past me with a thoughtful wave and a polite, “Excuse me, sir.” Considering I was out of my mind at that moment from exhaustion, profusely sweating into my eyeballs, I figured it was just a hallucination. But when I finally recovered from singlespeeding up the local death march climb known as Donkey Punch, I realized I wasn’t hallucinating.

The same pudgy, pasty-white middle aged man who resembled Milton from Office Space stood at the top of Donkey Punch looking out over the vast valley floor. Fiddling with a Disneyland-themed fanny pack, he pulled out a camera, adjusted his thick bifocals and took a picture with his bike in the foreground. As I approached, I noticed that this Fred had barely even broken a sweat on the entire three-mile climb, despite the fact that I was sweating like an atheist in the heart of the Bible Belt. I dropped my singlespeed in despair and ambled over to get a closer look at the bike he was riding.

It was a mountain bike of the electric sort, only this one had fat tires on it. Electric mountain bikes are bad enough, but an electric fat bike? Abomination doesn’t even begin to describe my feelings. At first I was appalled that this guy had the nerve to zip by me with such ease, and the fact that he was riding a motorized piece of machinery on a non-motorized trail. But I had to admit, my interest in his contraption was high.

I asked Milton if I could take his “bike” for a spin. He stumbled for a minute on a dozen or so words like “oh”, “hmm” and “let me see”, then finally agreed to let me ride it for exactly three minutes. “No more,” he said. He put his Casio computer wristwatch up close to his face and pushed a bunch of buttons; must have been nearsighted. “Okay, your time starts… now.”

I swung my leg over the hulking beast of bicycle and started pedaling. Like the hand of God gently pushing me along, my belabored pedal strokes became light and airy, helping the massive tires as wide as the spare on my Toyota float through the power-sucking sand that normally drains every last calorie of energy from my body. I didn’t think it was possible, but I actually had a smile on my face, a smile big.

I aimed the contraption towards the steepest uphill pitch I could find and went for it. Despite the bike weighing half as much as me, my pedal strokes zipped me straight up the short punch in the gut I’ve never been able to clean on a traditional mountain bike. What’s more, right in the middle of the effort, I got a text. Taking my hands off the bars while continuing to pedal, I replied to the text, and before I knew it, I was at the top. Hmm. Quite convenient. I could even do social media while riding this contraption. Twitter post sent. Facebook updated. Instagram grammed. Tinder, ready…

The Rungu Juggernaut Fat Tire trike is the gnarliest. The ASS has purchased three independent motors his three-wheel drive creation. (click to enlarge).

I looked at the timer on the bike. Only 30 seconds to get back to Milton. I could see him far below at the overlook, frantically waving up at me to come back. I let the brakes go and careened towards Milton. Despite the bike not having any front or rear suspension, the obnoxiously fat tires soaked up every little bump, chuckhole, and rock with remarkable plushness and damping perfection, as if I was riding on a big white puffy cloud of comfort. Another text came in, and without even thinking about stopping, I responded.

With only seconds to spare, I arrived back at the overlook. Milton grabbed the bike out from under me like a toddler who was forced to share his teddy bear with the classroom. I glanced over at my singlespeed laying lifelessly on the ground, a velocipede that now seemed like a completely Luddite creation in comparison. I turned around and looked longingly at Milton’s whip as he wiped down every surface with a handkerchief. It was the worst case of bike envy I’ve ever had. An electric fat bike. Who knew?

Like a boy who got his first kiss from a girl, then immediately dumped for the class football jock, I dejectedly got back on my 22-pound carbon fiber singlespeed wünderbike – or at least until three minutes ago it was – and headed home. I saw the future of mountain biking. I even got to ride it. I experienced what the industry calls a “game changer”. Singlespeeds – and all traditional mountain bikes for that matter – are now dead to me. I’m buying an electric fat bike. The Happy e-Fat Biker. HeFB. Huh. Doesn’t quite roll off the tongue like ASS, but I guess I’ll learn to live with it.

Editor’s Note: And then The ASS woke up and looked at the calendar…

Philip Keyes is one of the most respected names in mountain bike advocacy. Since co-founding the New England Mountain Biking Association (NEMBA) in 1988, Keyes has grown a grassroots club into one of the most successful advocacy organizations in the nation, with more than 5,000 members across New England. As recognition for his significant efforts in helping mountain bikers gain equal access to public lands, in 2008 Keyes was inducted into the Mountain Bike Hall of Fame.

So on Monday when Keyes sent this email to International Mountain Bicycling Association (IMBA) executive director Mike Van Abel and board of directors chair Robert Winston, it communicated two very clear messages. First, NEMBA is urging IMBA to support the Sustainable Trails Coalition (STC) and its efforts to overturn the blanket ban on bikes in Wilderness. Second, NEMBA wants IMBA to clarify its position on electric mountain bikes.

This email is one of several developments in recent weeks related to the blanket ban on bikes in federal Wilderness, the STC, and legislation surrounding e-MTBs. In the letter, NEMBA strongly recommends IMBA to support the STC, even after IMBA stated last week in a blog post by spokesperson Mark Eller that the organization will not be offering any support for STC. NEMBA warns IMBA that if they do not support the STC, they risk becoming “irrelevant” as the voice of mountain bike advocacy, particularly if STC ends up succeeding in its efforts.

Further, NEMBA wants IMBA to reaffirm their 2010 stance that eMTBs “should be regulated as with other motorized off-road travel.” Keyes goes on to say that NEMBA is, “concerned IMBA is poised to abandon this position.” NEMBA’s concern revolves around a recent independent study on the impacts of eMTBs, funded by the Bicycle Product Suppliers Association and PeopeForBikes. NEMBA is concerned that IMBA’s involvement with this research indicates they may use the data, possibly under pressure from the bike industry, to take a more accommodating position on e-bikes on trails.

This letter from NEMBA to IMBA is critically important, as NEMBA believes, “If bikes aren’t allowed in Wilderness, mountain bikers will always be second-class citizens on all public lands.” Further, “If IMBA believes that power-assisted bikes should be allowed on non-motorized trails then our fate will be sealed as being part of the motorized community.”

If you are a mountain biker concerned with future access to public lands, please educate yourself on this topic, as the two issues NEMBA addresses may well significantly shape the future of mountain bike access. To read the complete letter from NEMBA to IMBA, follow this link.

Surface 604 Boar E350 utility E-bike

Fat tires shine as one ventures to the beach.

What is it?

The Surface 604 Boar E350 is a fat bike with electric assist designed to get you riding around town more on your daily activities. Picking up some groceries, running errands, dropping off some packages, carrying your surfboards to the beach are all fair game for this fun utility bike.

It powered by a 350 watt Bafang torque sensing motor so it is a no-fuss assist bike that will give you an extra push when you need it. There are five levels of assist that manage the amount of pedal ‘matching’ power that it delivers and the maximum speed that it will keep delivering power at.

It is a fat bike so it is heavy at 57 lbs and very stable and comfortable with its 4 inch tires. It can handle rough roads, dirt roads and sandy terrain with ease. Using fat tires allows the rider to dial in the comfort as well as pressures down to 10 psi can be used for comfort and 20-30 psi for speed.

How can we say no?

How can we say no? (click to enlarge)

How is the power?

The 350 watt motor hauls this heavy bike + rider with ease. On flat ground, it accelerates quickly to max governed speed of 20 mph. At that point, the rider is working with just a light/medium effort at the highest level and it is difficult to maintain over 20 mph on human power alone when the motor cuts off past 20 mph. Thus it’s best to use lower levels of assist to get a better workout on flat ground.

On short hills, the Boar E350 can get up them with ease with the rider and motor delivering power to the big tires. But long hill climbs are not its forte though (as with many hub motors) as the motor can bog down at low speeds and overheat and shut down for a few minutes.

Hauling a trailer is no problem.

What fat tires?

The concept of an e-fat bike is a bit of an enigma as a fat bike is typically slow and an e-bike is usually a fast efficient commuter. So we anticipate this to be more of a fun, utility bike that is comfortable and stable. The big tires offer lots of traction so it’s pretty capable on sand, snow and rough terrain.

The interesting discovery is the slowness of the fat bike is negated by the assist motor. This bike is just fast and capable and the 20mph max laws negate the speed advantage that smaller tires would have provided.

So there are benefits to it with the downsides being shorter range (40 miles) and added weight (57 lbs) when moving the bike around.

The downtube is very stout.

How was it to ride?

It was fun to cruise around everywhere on this bike. It just gets up and goes and it’s just fun to get on the bike all the time and explore. Commuting to work too is a cool option that is quite entertaining with a bike like this.

The frame and fork are pretty harsh as they seem to use thick tubing. But the are plenty strong and stiff and comfort can be dialed in with low pressure on the 4 inch tires.

The real opportunity for this bike is to accessorize it with the optional racks so it can really carry more cargo and be used on more trips and errands around town.

Specialized Turbo Levo e-bike

What is it?

The Turbo Levo is Specialized’s first crack at the electric mountain bike market. The Big Red S took a look at all the eMTBs out there, identified issues and opportunities, and then created the Levo based on the existing Stumpjumper 6Fattie platform.

That means a 140mm rear travel platform with 3.0” Plus tires for max stability and traction. They chose a Brose mid-motor system and mated it with a battery integrated in the downtube. Wires and electronics were minimized to make it look like a mountain bike with minimal displays and distractions. At the heart of the system is a torque-sensing electric assist motor that adds to the rider’s effort. The harder the rider pedals, the more power the motor “assists.”

The Levo was comfortable tackling the most technical sections of the Amasa Back trail in Moab, Utah (left). We descended down some steep terrain (right).

Why an eBike — and why Moab?

The eBike is at the center of a brewing mountain bike storm, with riders divided by its emerging existence. Some feel it violates the purity of the sport with the introduction of electric assist and is akin to ‘cheating.’ Another big objection, especially in the U.S., is that e-bikes may harm trail access, as bicycles will become associated with motorcycles.

Climbing steeps requires skill but not as much energy.

The proponents of electric bikes see them as enabling tools that broaden the reach of mountain bikes to older/younger riders or those dealing with injury. They’re also seen as tools to narrow the wide gap between climbing and descending time. The key for now is to ride e-bikes only where they are allowed, which means OHV trails or trails were the land managers have permitted their use.

Specialized chose Moab for this press event because contrary to conventional wisdom, there are actually a ton of excellent OHV trails to ride. Indeed, this slickrock wonderland is both a mountain biking and 4-wheel and moto Mecca. Our Levo test rides were strictly on OHV trails, which are plentiful in Moab.

First ride impressions

The bike looked clean, devoid of instrument clusters and an obtrusive battery. Usually e-bikes are easily identifiable by a big battery occupying the front triangle. But on this bike instead of a bulky battery there’s a standard water bottle cage. The battery is neatly integrated into the downtube, occupying the bottom half of the tube. That power source weighs about eight pounds and can be easily removed with an Allen wrench. The battery is not structural, so its presence or absence does not affect frame stiffness.

Setting up is critical just like most high performance bikes.

The only giveaway that the Levo is an e-bike is the massive bottom bracket area. The motor is cleanly integrated here, with custom brace plates designed to hide the motor and add stiffness to the bottom bracket area, which is fairly wide so the bike can only handle a single front chainring. Q-factor is wider than a normal bike.

There is no display on the handlebar to indicate vital information to the rider. Instead, those duties are performed by three buttons and 10 LEDs. It is a clean affair but not very ergonomic. One has to reach down to the side of the downtube, reach down to hit the mode buttons, and look over to check the current mode and remaining battery life. If you want better information and control, a smartphone or Garmin with Levo compatibility is required and needs to be mounted on the bars.

2016 Sea Otter Classic

However you may feel about electric bikes on your local trail network, you cannot deny how cool this bike looks!

However you feel about e-bikes on your local trail network, there is no denying this bike’s cool factor (click to enlarge)

The topic of e-bikes was unavoidable at this year’s Sea Otter Classic. Nearly all the major manufacturers have (or will soon have) some sort of pedal assist bike. There was even an eMTB race won by former world champ Christoph Sauser (see Friday “Mountain Bike” results here). But the best “cheater” bike we saw wont be coming to a shop or race near you anytime soon.

For those of you who aren’t motorcycle enthusiasts, a scrambler is typically a vintage bike that has been customized to allow some degree of off-road use. For some, that means knobbies, but others have taken the concept to greater lengths.

In honor of that tradition, Specialized creative director (and long time moto nut) Robert Egger built this fully custom electric assist pedal bike. We’re pretty sure it was the coolest bike at Sea Otter this year, but let us know what you think after scrolling through the gallery below.

Updated: Monday, April 18th, 2016

In case some you aren’t familiar with Robert’s previous art bikes, we’ve updated our gallery to include a few of his previous works – many of which were also inspired by motorsports.

This article is part of Mtbr’s coverage of the 2016 Sea Otter Classic in Monterey, California. For more from Sea Otter CLICK HERE.

However you feel about electric bikes on your local trail network, you cannot deny how cool this bike looks! How classy is that leather Brooks bag? Custom spacers allow the scrambler to use moto bars. This bike runs on a mixture of human power and electrical current, so what’s in the tank? At least the motor is filled with spares. Very few pieces on this build are off the shelf. Wait, are those Ohlins shocks? Designed and built in California. 427 Ford Cobra. Can you guess what movie inspired this chopper? The Urban Cowboy. Pronounced "eff You See Eye," or FUCI for short, this is one of our favorite art bikes ever. Can't say the Speed Queen is our favorite Egger designed bike The Salt Flat Out may have pedals, but it's that gas powered motor that will help it set land speed records to the bar. The cafe racer is another gas powered art bike designed and built by Robert that borrows heavily from the custom motorcycle scene. The Moto Demo mates a downhill frame and a pit bike motor for what we imagine is one of the best pit bikes of all time. More Cobra inspired goodness, this time with BBQ capabilities. Human powered 426 Hemi. Now this is the kind of bike that mall cops should be riding. And finally, the Drag Stripper.

Hidden motors have been causing a ton of controversy in the road cycling world for the last couple of months after one was found in a race. Yes, we know, unbelievable. Anyway, the GMBN got to thinking: if these motors are used on the road and in cyclocross, does that mean that there’s an advantage to having one on a cross-country bike? Check the video to find out about the results.

//www.youtube.com/watch?v=sUaBaPHxACA

$3000 Vivax Motor

The motor used in this bike is called the Vivax found here www.vivax-assist.com. It is the most well-known one in existence today providing 150 watts of power for an hour and a half while adding 4 kg or 9 lbs of weight. The motor operates with a manual switch that activates a seat tube motor to drive the bottom bracket at a specified cadence. Since there is no clutch mechanism, when the rider takes his feet off the pedals, the cranks keep spinning. When the rider freewheels and stops pedaling, the motor shuts off automatically and needs to be turned back on to provide assist again. It is a very crude and inefficient system for the variable power demands of mountain bike trails.

There may be other, more advanced systems that exist now that we are unaware of. Certainly, the advancements with these kinds of technologies will be rapid in the years to come.

Test conditions not ideal for type of assist

In the test, they failed to tell us the amount of climbing involved and the type and consistency of the climbs. The motor they were using will be more effective on a course with a long, consistent climb that will allow a rider to utilize the motor all the way up a hill. Given that the motor shuts off every time the rider freewheels, it is pretty inefficient for any kind of technical riding.

Bikes not the same

Perhaps the biggest failure of this test is the bikes are not identical or even comparable. The human powered ‘only’ bike is a carbon Canyon bike with the best components available. It has full XTR, carbon wheels and 500 gram Schwalbe Rocket Ron tires.

The assisted bike is an aluminum ‘no-name’ bike with mid range components and Schwalbe Racing Ralph tires. By our calculations, it is 4 lbs heavier than the carbon rig.

The Vivax assist system adds 4 lbs of weight to the bike. Thus the aluminum ‘assisted’ bike ends up weighing 8 lbs more.

Given identical bikes and a course with more extended climbs, we have no doubt the assisted bike will have an advantage over the normal bike. And in the coming years with more powerful motors and lighter batteries, the advantage will just grow.

Thus, testing needs to be developed and instituted in XC racing to prevent this form of cheating in bike races.

Haro was at the Sea Otter Classic showing updates to their Shift Plus for model year 2016 and a new long travel version of their Shift called the Shift LT. The Shift LT is designed to be a more all mountain/enduro ready rig to handle more gnarly terrain and bigger jumps than last year’s version. There will be 3 trim levels available including the Shift R5 LT, Shift R7 LT and the Shift R9 LT – which is closest to the model shown here. The R9 will come with a Shimano XT 1×11 drivetrain, XT 10-42 cassette, XT derailleur, XT shifter, new Praxis crankset, all Ritchey cockpit, dropper post (which may or may not be the Manitou model shown here), new RockShox Revelation 140mm fork and RockShox Monarch shock with big can.

The Haro Shift LT features the new crankset from Praxis.

The Haro Shift LT will be available in September of this year. Pricing for the Shift R9 LT will be comparable to the Shift Plus so that model should come in right around $2600 to $2700.

For 2016 the Shift Plus gets internal cable routing for electronic shifting and new graphics.

For this year’s update Haro Shift Plus, the bike now has internal cable routing for XT/XTR Di2 or you can still run traditional housing cables externally. The black and orange color is new as is the new 130mm fork (last year’s version ran a 120mm fork up front).

Haro is committed to the mountain bike category and for 2016 they have four dual suspension bikes with one Plus bike. For model year 2017, they will be expanding to eight full suspension models. When we asked if they plan to extend the LT platform to their Plus bike, MTB Product Manager Jean-Luc Ferre said, “we don’t have any prototypes built at the moment, but we may go with longer travel Plus bikes in the future.”

Also on display was a prototype eSubvert hardtail with Shimano electronic motor.

We don't have much info about the new eSubvert, but it could be an option for casual bikers.

Bulls Bikes is German brand that has built their reputation around race bikes that started in 2007 when the first Team Bulls was formed. This included bicycle professionals Karl Platt and Stefan Sahm and together they garnered attention from cycling fans due to their consecutive successes in long-distance competitions. They won the legendary Cape Epic, Transalp and Trans Germany in their very first year. Besides endurance, cross country and marathon events, Bulls even has a downhill team (their DH bikes have not yet made it to America yet.)

Like many other brands just starting here in the States, Bulls is using the direct-to-consumer business model. They make several different kinds of bicycles for their European market and they continue to expand their US offerings this year with the Copperhead alloy hardtail, the Wild Edge Team 29 and a full suspension e-Bike.

The Copperhead 29 RSi is new from Bulls Bike for 2016.

Bulls Bikes Copperhead 29 RSi

The Copperhead 29 RSi is new for 2016 and it is their top of the line alloy hardtail. The geometry and construction is designed to keep this 29er agile and nimble, while retaining the advantages of bigger wheels. The frame is made from 7005 triple-butted aluminum and has internal cable routing, a tapered head tube and a press fit bottom bracket shell. The frame has a bit longer wheelbase than many other 29ers currently out there, which Bulls feels makes them more stable at race speeds.

Suspension duties are handled by a Fox 32 Float fork with 100mm of travel and a remote lockout to keep things efficient. The Copperhead has thru-axles front and rear and the Shimano XT 2×11 drivetrain is solid. This bike also features a side swing derailleur in order to make shifting easier and more stable. Claimed weight of a medium size Copperhead 29 is 25.35 lbs. The bike is available in four sizes (SM, MD, LG, XL) and one graphic (Black Matte/Shiny Yellow). The Bulls Copperhead 29 RSi is available now online and has an MSRP of $1,999.

The Copperhead 3 RSi is the almost identical to the Copperhead 29 but it is optimized for 27.5" wheels. Same parts spec and same $1999 price.

For those of you out there that prefer your big wheels not so big, Bulls offers the Copperhead 3 RSi 27.5. This bike is also new for this year and features the same frame construction as the Copperhead 29, but is optimized for 27.5″ wheels. It has a Fox 32 Float fork with 100mm of travel, same Shimano XT 2×11 drivetrain and side swing front derailleur. Claimed bike weight is slightly lower at 25.13 lbs and it comes in the same 4 sizes and same grey finish with the same $1,999 price.

Bulls Bikes Wild Edge Team 29 +

The Wild Edge Team 29 + is a bike that we saw previously at last year’s Sea Otter Classic. The Wild Edge Team 29 series features a monocoque carbon frame that has been tested and developed in competition and endurance racing. The name might be confusing for some, as it is NOT a Plus bike. Rather the “+” designation means their top shelf Shimano XTR equipped model. This bike has a claimed weight of 22.70 lbs and the XTR kit and RockShox RS-1 fork results in a price of $5,799. There is also a Shimano 1×11 version available at $3,999 and a Shimano 2×10 version available at $3,399 (both with the RockShox RS-1 fork).

Like it or not, e-bikes are coming. For a long time Mtbr ignored them like that moldy Tupperware in the back of the office fridge. But with technology improving rapidly, we can’t look away anymore. While early models were cobbled together hack-jobs, well designed bikes such as the Specialized Turbo Levo have put cyclists and land managers in the U.S. on notice.

In Western Europe alone, e-bike sales are projected to top 1.6 million. Here in North America, Navigant projects sales of 152k units.

In Western Europe alone, e-bike sales are projected to top 1.6 million units. Here in North America, Navigant projects sales of 152,000 units (click to enlarge).

In the rest of the world e-bikes are already a huge business. Sales are expected to total $15.7 billion this year and will reach an estimated $24.3 billion by 2025 according to Navigant Research. In China, there are already more than 200 million e-bikes in use and sales are booming in Western Europe.

The market has now evolved to where we as a media outlet cannot continue to overlook these bikes as mere curiosities. Like Donald Trump, e-bikes aren’t going away. Ignoring them isn’t going to change the reality of the situation. These motor-powered two wheelers are coming, and they raise some interesting questions about the future of cycling.

E-fat bike? Haters gonna hate.

E-fat bike? Haters gonna hate (click to enlarge).

Our job is to report and educate on new trends and products in an unbiased fashion. And according to our annual audience survey, a number of you have either expressed a growing interest or remain undecided about e-bikes. As the technology continues to evolve and solutions to current issues regarding access are resolved,  that interest will continue to increase. There will always be a vocal minority whose complaints can be seen in the comments section. That’s the nature of the internet. But if we’re to take those negative comments to heart every time a new technology emerged, we wouldn’t be reporting on 29ers, fat bikes, 27.5, plus, and so on.

That doesn’t mean we are trying to shove e-bikes down your throat. Everyone on the Mtbr staff has had the opportunity to ride one and while we all agree they’re fun, they’ll never replace our real bikes (at least not until we’re old and decrepit). However, as brands such as Shimano and SRAM enter this market, we must acknowledge the importance of this new segment.

Due to growing concerns regarding land management and trail access, there’s alot of rage against e-bikes - but it’s hard to deny how fun they are once you give it a go.

So whatever our personal feelings may be about e-bikes, it’s our obligation to discuss and review components objectively. That said, we do want to lay down some ground rules. Just like you, we have concerns about the potential impact of e-bikes on existing and future trail networks and believe they should only be ridden in designated areas. We also believe there’s a difference between an e-bike and a motorcycle and that difference comes down to throttle application and maximum power output.

We will not review or report on any electric two wheeler that puts out more than a maximum average of 250 watts or utilizes a hand operated throttle. If it can be powered without pedaling, it’s not a bike, and it won’t be featured here. That’s our promise. Going forward however, you will see the occasional article or review about mtb specific e-bikes pop up on our homepage, but don’t worry. We’re not changing our names to e-Mtbr anytime soon.

In the ongoing debate about e-bikes, this might be the best in-favor argument we’ve encountered yet. Martyn Ashton was once among the world’s best trials riders. But a freak accident left him paralyzed below the waist. Riding career over, right?

Not with this one-off Canyon Sender downhill bike that Ashton rides down Scotland’s Fort William World Cup course in the first video below. Utilizing a mix of stock components, specialized 3D printed parts, and a 3400-watt electric assist motor engaged by a throttle, Ashton’s able to pilot the bike on one of the most famous race tracks in mountain biking.

Ashton call it the most beautiful bike ever.

Stock parts on the Canyon DH bike include Hope bars, stem, brakes and wheels, a FOX 40 200mm fork, FOX Float X2 shock, Crankbrothers Mallet DH pedals, and Schwalbe Magic Mary tires.

The bike also benefited from a number of 3D printed bits, including a set of brackets that keep the pedals from rotating, and another 3D printed part to hold the 44-volt lithium ion battery that powers the bike. The carbon fiber coasted seat wraps around Ashton’s hips for protection (he crashed several times during the video shoot), and the drivetrain is Shimano Saint adapted for a 7-speed cassette. You can learn more about the bike in the second video below.

SRAM EX1 e-bike component group first look

Why an e-bike-specific group?

We’ll just get to the heart of the matter and ask/answer that question. No, it is not required, as e-bikes can manage out there with any old drivetrain, brakes, and suspension. But spend some significant time on an e-bike and one will realize that there are quite a few compromises with current systems. The experience can get a whole lot better and SRAM is well ahead of the curve in addressing the issues.

Those issues can be boiled down to the following:

  • Shifting under power is rough and clunky
  • The shift steps don’t make enough of a difference
  • The durability of the drivetrain
  • Brakes don’t have enough power to stop bike precisely

These are all due to two things: The e-assist can double the power of the rider and riders are trained to ‘soft-pedal’ while shifting but the assist motor can be kicking in while the rider is shifting. Also, e-bikes are heavier by about 20-25 pounds of un-sprung weight and it can affect the ride, as the brakes are stressed and the bike pushes into corners or fades in long descents.

The forged block is then milled and treated.

The heart of the system

The heart and soul of the SRAM EX1 system is its E-BLOCK cassette, which is designed to provide the optimum E-MTB gear range, as well as increased battery longevity and component wear life. Its 11-48, 8-speed design allows a 436-percent gear range. Based on its testing, SRAM believes this is the ideal e-mountain bike gear range.

The 8-speed design incorporates big (30-percent average) steps between gears. The big steps, in combination with the EX1 group’s single-action shift lever, reduces riders’ tendency to double shift. The single-shift design significantly helps chain and cassette wear.

The tooth jumps are in 30% increments instead of the usual 16% on normal bikes.

The tooth jumps are in 30% increments instead of the usual 16% on normal bikes (click to enlarge).

The cassette, machined from case-hardened tool steel, is narrower than a 10- or 11-speed cassette, which helps maintain a straighter chain line throughout the gear range. Engineers were then able to pair the cassette with a slightly wider, tougher chain to increase durability, which is critical in the E-MTB environment, where shifting is typically done at very high torque and low pedaling cadence, versus the low-torque, high-cadence environment of traditional mountain biking.

The E-Block cassette uses a non-XD driver body. The larger virtual front sprocket provided by a midship motor all but eliminates the need for a 10-tooth cassette cog, so the E-Block design’s focus is the larger, “climbing” cogs. By combining the proper climbing gears with motor output, battery power is optimized, and lasts longer given the same conditions.

The EX1 is seen here on the Moustache e-mtb.

Shifting performance and feel is signature SRAM. As stated previously, the trigger shifter has been designed to shift once at a time — not multiples — but the action is positive and exact. The EX1 derailleur employs the rugged, X-Horizon design seen in XX1 and X01 derailleurs, with a redesigned clutch, cage and pulley design specifically for the 48-tooth cog.

The rest of the goods
EX1 X-Horizon Rear Derailleur

The EX1 derailleur capitalizes on the robust build and precise shifting attributes of the X-Horizon design, to create the world’s first derailleur specifically made for E-MTBs. Engineered to handle high-torque, low-cadence shifting across the 11-48 tooth E-Block cassette, the EX1 derailleur gives E-MTB riders clean, confident shifts, so they can spend more time enjoying the ride.

EX1 X-Horizon Features:

  • SRAM X-Horizon design that reduces shift force, ghost shifting and chain slap
  • 12-tooth X-Sync pulley wheels
  • The EX1 derailleur is purpose built for E-MTB

EX1 X-Horizon Specifications:

  • Speeds: 8
  • Cable pull ratio: 1:1
  • Max tooth: 48
  • Color: black
  • Pulley bearings material: Steel
  • Cage material: Aluminum
  • Weight: 289g
EX1 X-Actuation Trigger Shifter

Eight speeds are key for optimizing for the e-assist with 30% gearing changes on each shift, alleviating double shifting and over shifting. Single precise gear changes increase battery life and help to decrease component wear.

EX1 X-Actuation Specifications:

  • Speeds: 8
  • Max upshifts/downshifts: 1
  • Multi-position: Yes
  • Part weight: 122g

EX1 Chain

The high torque loads of E-MTBs require tough components. The straighter chain line EX1 offers allows the use of a chain that is wider and more robust than those found on drivetrains not specifically engineered for E-MTBs. The 8-speed EX1 chain has been engineered to run quiet across the gear range and transmit more power to the rear wheel.

EX1 Chain Features and Benefits:

  • EX1 chain is wider and designed for the high-torque, heavy-duty use of E-MTB
  • Compatibility: 8-speed
Pricing
  • E-Block cassette: $390
  • Rear derailleur: $142
  • Shifter: $48
  • Chain: $25
  • Brakes: $133 each
  • Crank: $50
  • Sprocket: $20
Summary

We’ve been riding e-bikes on the roads and OHV trails for a couple years now and we have noticed several weaknesses of commuter systems adapted for dirt trails. Most notably, the systems simply cannot handle the dirt, torque, shifting requirements needed for steep, dirt trails. SRAM is ahead of the issue here and is solving several problems that we have noticed. The shifting performance of the EX1 is simply incredible as the rider can shift under power at 20%+ grades. Precise, consistent braking is now available in spades too. Next stop, optimized suspension.

The Angry Singlespeeder: Strava versus eBikes

A yeti was spotted riding a MORB at Sea Otter. No word on whether he got the KoM.

In no way do his maniacal diatribes about all things bike oriented represent the opinions of Mtbr, RoadBikeReview, or any of their employees, contractors, janitorial staff, family members, household pets, or any other creature, living or dead.

“Uh, excuse me. I’d like to pass please.”

The words came from behind as I was climbing Hurl Hill at the Sea Otter Classic this year. Not that I was riding super slow or anything, so the polite request came as a bit of a surprise, especially considering the dude didn’t even sound like he was breathing hard.

Not being one to block someone else from passing, I pulled over to the side and looked back to see a guy in his early 50s with his saddle way too low, knees practically knocking him in the chest, effortlessly cruising past me uphill at a clip that even Nino Schurter couldn’t maintain for very long. The guy passed and sheepishly apologized, almost as if he was embarrassed about it.

“Thanks, heh heh. Sorry. I guess I’m cheating. I’m not really this quick.”

As a parting gift, the guy’s low hanging baggy shorts prominently showed off his exposed butt crack. All I could do was shake my head and laugh in amusement. Of course the guy was on an electric mountain bike. It was the first time I’d been passed by one on the trail.

Two weeks later, I was back home in Reno, Nevada, out on a solo trail ride. I approached an uphill switchback and saw a cheater line blazed into the earth, shortcutting the corner. Two turns up from that I saw another cheater line. I grumbled aloud about the fact that someone was “Biebering” the trails, and not 30 seconds later a Lycra-clad speed freak came railing downhill towards me.

Most people would be hard pressed to even recognize this bike as an eBike, but it is.

Most people would be hard pressed to even recognize this bike as an eBike, but it is.

The guy couldn’t be bothered to slow down even for a moment, let alone yield to an uphill rider. I held my ground and kept cranking uphill, narrowly clipping bars with other rider as he whizzed by, chasing a coveted Strava KoM segment I guessed. Unlike the passing eBiker, I was not in the least amused by that near collision.

The rise of technology in mountain biking has created a lot of amazing advancements such as composite frames and wheels, high performance suspension, electronic shifting, and hydraulic disc brakes. Without a doubt, mountain bikes are better and more capable than ever before. But technology has also given birth to more controversial innovations such as Strava and what I like to call MORBs (motorized off-road bicycles), of which both have some very vocal detractors. So which one is can cause more problems? Strava or MORBs?

One of my personal biggest gripes with Strava is that it’s had a significant negative impact on the social aspect of mountain biking. Before Strava, if people wanted to compete with one another, they’d either do it in a race or they’d bang bars with each other on a weekly group ride. Whoever was the fastest was the first up or the first down on that particular week. If you wanted to challenge the fastest, you showed up and went mano-e-mano with the reigning champ. It was a healthy, social way to get out those competitive urges.

Strava has turned a lot of would-be casual rides into races against a ghost rider.

Strava has turned a lot of would-be casual rides into races against a ghost rider.

But ever since my friends started using Strava, the social nature of our weeknight rides changed. What used to be a mandatory 20-minute warm-up and social chat before hammering each other became an instant race against some ghost rider, with people disappearing off the front, some never to be seen again for the rest of the ride. The reason?

“Sorry man, I was going for the KoM on that segment.”

But when it comes to MORBs, the social element is different. Although MORBs enable a novice, unfit rider to climb uphill at the same speed as a professional, eBikes can actually promote a more social environment because it levels the playing field, enabling less fit riders to hang with a group longer at an exertion level that still allows conversation. Sure, some riders in the group might not like it that Joe Beer Gut is “faster” than them, but who the hell really cares? Is your ego really that fragile?

And unlike Strava, which sometimes lures people into racing downhill faster than they should, MORBs don’t really make riders any faster on the descent. Depending on the terrain, the much heavier and more cumbersome MORB is actually slower downhill. I’d never choose a MORB over a well-designed trail bike for a long, challenging descent.

On the bigger and more controversial issue of trail access, I also believe that Strava can cause more damage than eBikes. Why? Because people riding MORBs don’t advertise to the entire world that they’re poaching a non-motorized trail. The function of a MORB is not to track and display where someone rode, it’s simply a technological enhancement to allow someone to ride longer distances at a pace they otherwise wouldn’t be able to. The core function of Strava is track where one has ridden. Not only can Strava show the world that someone just poached an illegal trail, but it also shows they are the fastest idiot to poach that illegal trail.

Land managers aren’t using MORBs to get trails closed to mountain bike access, at least not yet. But there have already been incidents where Strava was used to either prove mountain bike trespassing, or show peak rider speed numbers to justify why a trail should be closed to mountain bikes. The latest example was earlier this year in Los Altos, California, where Strava data was used to ban mountain bikers from Byrne Preserve. So when it comes to the topic of trail access, I personally think Strava is more likely ammunition for anti-mountain bike advocates to justify trail closures.

Biebering a trail involves dumbing it down to make it faster.

Biebering a trail involves dumbing it down to make it faster.

And the third aspect has to do with trail damage. I’ve done several rides on a MORB that’s purely pedal assist and I still haven’t been able to make the bike roost like a throttle-twisting dirt bike. Despite what MORB haters say, in my experience, pedal assist MORBs don’t cause any more trail damage than a traditional mountain bike.

If I could only say the same for Strava. Now of course Strava itself isn’t causing trail damage, but because of the inherent competitive nature of the app, it’s encouraging riders to go out to their local trails and Bieber the hell out of them. What is Biebering? It’s taking a trail that used to be challenging and technical and making it lame by shortcutting or removing obstacles, all in the name of going faster to capture that coveted KoM.

Now this column isn’t some push to get MORBs legal on non-motorized trails. I still firmly believe that MORBs should not be permitted on non-motorized trails. At least in the foreseeable future, aligning mountain bikes with MORBs in the United States is advocacy suicide for our sport. However, if mountain biking didn’t have such vocal detractors, I wouldn’t see a problem with pedal assist MORBs on more trails.

But I personally believe Strava has had a significant negative impact on the social nature of mountain biking, its data tracking capability has been used by land managers and mountain bike opponents to close trails, and its competitive segment aspect has altered existing trails. And despite MORBs receiving a lot of hate from mountain bikers, there’s an undeniable positive aspect of them, especially with people who also hate Strava. MORBs are the ultimate KOM killer. Once people start riding MORBs while using Strava, nobody will know which segments were truly human powered. If for whatever reason MORBs don’t end up gaining widespread acceptance, if they can at least kill the competitive segment aspect of Strava and make it irrelevant, in my eyes MORBs will have been a huge success for regaining the social nature of our sport.

Biebering a trail involves dumbing it down to make it faster. A yeti was spotted riding a MORB at Sea Otter. Strava has turned a lot of would-be casual rides into races against a ghost rider. Most people would be hard pressed to even recognize this bike as an eBike, but it is.

The Xduro AllMtn is Haibike’s entry into the electric all mountain/trail bike category.

The Xduro AllMtn is Haibike’s entry into the electric all mountain/trail bike category.

If the mere thought of e-bikes makes that one vein in the middle of your forehead start to bulge, then I highly recommend you watch this Brandon Semenuk edit instead of reading any further. Why? Because today we’re going to take a look at the Haibike Xduro AllMtn RX. It has 150mm of travel front and rear and rolls on 27.5″ wheels.

The complete bike retails for $5900 and is spec’d with Fox suspension, a KS Lev dropper post, and Shimano XT components. The build also includes a Bosch motor and Li-Ion 36 Volt, 400 wh battery.

The Xduro AllMtn had 150mm of travel and a relatively steep 68 degree headtube angle. For comparison, the 140mm travel Specialized Turbo Levo has a 66.5 degree headtube angle.

Geometry

For something with the word all mountain in its name, the geometry is surprisingly conservative. For instance, the frame has a 68-degree head tube angle, which is almost two degrees steeper than most bikes in this category. It also has a much shorter reach and longer chainstays. To understand why a call to Haibike was in order.

According to their Senior R&D engineer in Germany, it’s not fair to compare the geometry of traditional bikes to those of e-bikes. Due to the motor, electric bikes have longer rear ends. To compensate and ensure the bikes are still agile, Haibike positions the rider further back by shortening the top tube and using a slacker seat tube angle.

The Haibike geometry differs from traditional mountain bikes due to the position of the motor. To help compensate for the longer rear end, they use a shorter front-center to help centralize rider weight.

The Haibike geometry differs from traditional mountain bikes due to the position of the motor. To help compensate for the longer rear end, they use a shorter front-center to help centralize rider weight.

While this may seem counterintuitive, it helps position the rider more centrally. This works because e-bikes are ridden differently than normal bikes. Due to the power assist, riders will spend the majority of their time in the saddle. Therefore the combination of a shorter top tube, slacker seatpost, longer head tube, etc. allow the rider to maintain the same upper body position on an e-bike as they would on a regular bike.

Where this philosophy breeds confusion is in regards to frame sizing. Rather than employing the conventional S/M/L format, Haibike uses frame heights. This is apparently common practice in Germany and indicates the length of the seat tube. In the future, they’ll be moving to more traditional sizing, but for now, it’s best to rely upon top tube length to gauge your size.

I ride medium frames that generally have a 23.5” (596mm) top tube. This placed me on Haibike’s size 46mm frame which has a 22.8” (580mm) top tube. Their largest model has a 24.4” (620mm) top tube, so riders over 6 feet should definitely try before they buy.

The Boltron was developed in conjunction with Motocross suspension expert WP.

The Boltron was developed in conjunction with motocross suspension expert WP.

With ebikes sales surging in Europe and Asia (and starting to gain traction in North America, too), manufacturers are rushing to develop components that can withstand the heavier weights and higher forces that these two-wheelers exert.

To help meet these demands, Magura turned to the experts at WP, which is owned by KTM. They manufacturer suspension components for the Austrian motorcycle brand and its subsidiary Husqvarna.

Together, the two companies developed the Boltron. This inverted fork has 35mm lowers, 40mm outers, and can accommodate either 27.5+ or 29er wheels. It will ship with either 120mm or 150mm of travel. Sag and rebound can be adjusted, but the fork has fixed compression that can only be modified via shims.

Official spec’s from Magura regarding the new Boltron inverted fork.

The Boltron uses the 20x110mm axle standard. Weight for the entire fork, including leg protectors, thru axle, and an uncut steer is 2200 grams. Due to the weight, it’s not likely we’ll be seeing this fork produced for regular mountain bikes anytime soon.

Magura will officially launch the Boltron at Eurobike and it will be available on KTM and Haibike ebike models later this year.

The irony is that the amount of hate some mountain bikers have towards MORBs ranks on the same level as hateful old hikers whose goal in life is to keep mountain bikes off every inch of singletrack.

The irony is that the amount of hate some mountain bikers have towards MORBs ranks on the same level as hateful old hikers whose goal in life is to keep mountain bikes off every inch of singletrack.

“No way.”

My buddy stared at the none-more-black Specialized Turbo Levo FSR and shook his head. He refused to ride it or even simply swing a leg over it and just take it around the block. After a couple minutes of convincing and promising not to snap a picture of him riding a MORB (my acronym for motorized off-road bicycles) for all of social media to see, he agreed to give it a try. Ten minutes later he came back with a giant smile on his face. When I asked him what he thought, with a contemplative look, the former MORB hater simply said, “It’s interesting.” That’s exactly what I said after my first ride.

Another friend simply refused to ride it no matter how much convincing I did. He even said, “If I ever see some lazy ass on my trails with this piece of electrified crap, I’m gonna get in their face.” Oh really? What if the person has a terminal illness and they only have 6 months to live? What kind of a–hole are you going to look like when you get in someone’s face and draw conclusions about them? A MORB might be the only way someone can still ride a bike and enjoy “your” trails, so for those who want to play trail police with strangers, my advice is to heed the age old passage, “Judge not, lest ye be judged”.

Read the first ride review of the Specialized Turbo Levo here.

With the exception of a Segway, I’ve never not had fun on two wheels, but based on the extreme prejudice and hatred that electric-assist off-road bikes have generated, you’d think these contraptions were the devil reincarnated. The irony is this: The amount of hate some mountain bikers have towards MORBs ranks on the same level as hateful old hikers whose goal in life is to keep mountain bikes off every inch of singletrack. And the bigger irony is, most of those who hate on MORBs have never even ridden one. Have we learned nothing from the 30-plus years of hatred and prejudice of anti-mountain bike folk?

This is not meant to be a column about promoting how cool or useful MORBs are. Rather, I agreed to ride a Turbo Levo to understand exactly what it is, what it can do, and what it can’t do. The mind is like a parachute, it only works when it’s open. So with an open mind, I brought a Turbo Levo up to Downieville in order to sort it out on an extensive network of moto-legal trails to determine its capabilities and pitfalls. Whether you like it or not, at least for now, these bikes are here to stay. So instead of hating on them like I admittedly did for a bit, I’ve chosen to better understand them by riding one.

A MORB could be a very useful machine for trail crews who need to maintain hard-to-access motorized and non-motorized trails.

A MORB could be a very useful machine for trail crews who need to maintain hard-to-access motorized and non-motorized trails.

Riding a MORB

Although my buddy Evan calls the Turbo Levo a “48-pound dirt bike you can pedal”, it’s not that good. First off, you can’t roost the rear tire on this machine. It’s pedal assist only with maximum output of 530 watts and an average output of 250 watts. Compared to a dirt bike, that’s a paltry amount of power. Sure, the Turbo Levo is fun going uphill on pretty steep pitches so long as it isn’t too technical, but once those steep pitches get littered with big loose rocks, the fun ends. Pushing a 48 pound mass of battery and motor uphill taxes your lexicon of cuss words as much as it does your legs and lungs.

Because of the slack 66.5-degree head tube angle and abundant mid-ship weight, the Turbo Levo forces you to ride at the very front of the cockpit to keep the front end planted on steep uphill pitches. And because of its weight, the Turbo Levo naturally wants to fall over at low speed going uphill. With no throttle to upright the bike, once the MORB starts falling over, that’s all she wrote. Contrary to what some might think, the Turbo Levo will not out climb a mountain bike when the terrain gets steep, rocky, and technical. You might go a little further, but at some point, you’ll be pushing. And it’s a hell of a lot easier to push a normal mountain bike than a MORB.

So long as you keep the MORB to trails that aren’t very technical, it’s impressive how much terrain can be covered. Climbing to the top of Empire Creek Trail from Downieville is a serious undertaking to the tune of 12 miles and 4,000 vertical feet. On my trail bike it takes me at least two hours, and by the time I reach the top I’m drenched in sweat from the effort. On the MORB, I reached the top in a mere 90 minutes with only a mild bead of sweat on my brow. But there was one glaring issue – the 12-mile climb, even in Eco mode (30 percent assist), drained the battery to only one remaining bar. Thankfully the ride back home was almost all downhill, but on that two-hour ride it became clear that for big adventures, the Turbo Levo battery is not yet up to snuff.

Whenever we discuss e-bikes on Mtbr, the comments section erupts with all manner of vitriol. It almost feels like we posted a video of ourselves clubbing baby seals. But the conversation is far different overseas. I know, I thought it was bs too, then I spent a few weeks in Europe. E-bikes are everywhere. In fact, there are entire tourist destinations that have been built around the concept of e-bikes, with trails for all ability levels that link to charming cafes with charging stations.

And you thought I was kidding. Photo by Dan Milner and Gaudenz Danuser

This tourism model was first explored by the town of Flims in Switzerland. Located in the Swiss Alps, the economy of the area is largely dependent on snow sports, but e-bikes have allowed them to expand their appeal as a summer destination.

For some perspective on how the other side lives (and e-rides), Trek flew Mtbr to Flims for the European launch of its Powerfly e-bike product line. This range is Trek’s most popular in Europe, and after nearly five years of production, they’re bringing a select number of models to the United States.

Trail Advocacy and Education

Now before you arm yourselves with pitchforks, remember that Trek is the same brand that just pledged to donate over $1 million to NICA over the next five years.

The crew at Trek understands that trail access in the U.S. has been a hard fought battle in many regions, so they’re working hard to educate their dealers. They’ve held webinars, hosted dealer seminars, and are creating a 30-minute course on eMTB products and issues for their Trek Certified Service course.

On the consumer-facing side, they’ve also partnered with People for Bikes to develop a map that highlights local eMTB trails.

While the Euro’s get sixteen different Powerfly models, us Americans only get four.

While the Euro’s get 16 different Powerfly models, just four are coming to the U.S. for now.

The Spec

With that PSA out of the way, let’s move onto the bikes. While the Europeans get 16 Powerfly models, the U.S. market will make do with four for now: three 29er hardtails and one full suspension set-up.

Both the men and women’s models share similar builds, but have different frames and touch points.

Both the men’s and women’s models share similar builds, but have different frames and touch points.

At the more affordable end of the spectrum is the Powerfly 5 and Powerfly 5 WSD, both of which retail for $3000. The women’s specific design (WSD) utilizes a different frame, that has a heavily sloped top tube for improved clearance. It also sports women’s specific saddle, bars, and grips. Both the male and female versions share a similar build spec, which includes a RockShox Recon fork, Shimano Alivio 9-speed drivetrain, and Shimano hydraulic brakes.

The Powerfly 7 retails for 4k and has an improved product spec. In Europe, a women’s specific version of this build is also available.

Barney Franco of Bulls eBikes presents the Dail-E Grinder, the Lacuba EVO E8, the E-Stream EVO 3 Carbon 27.5+, and the Monster E FS Fatbike — just some of the many featured new releases from Bulls eBikes.

Bulls Bikes Booth Interbike 2016 Booth

Bulls, a German bike manufacturer known for its value-focused mountain, road, and cyclocross offerings, is the latest to expand into the emerging e-bike market. Quite aptly, Bulls is grabbing the proverbial e-bull by the horns, unveiling 20 new e-bikes at Interbike this year. In contrast to the non-electric offerings from Bulls, which are distributed via the direct-to-consumer model, the new e-bikes will be sold in retail stores only.

Barney Franco presents four of the new models, beginning with the Dail-E Grinder. This touring-style commuter is equipped with a Bosch mid-drive performance line power unit, which is able to produce up to 500 watt hours. The bike also features a Shimano Ultegra Di2 drivetrain, hydraulic disc brakes, fenders and racks, and front and rear Supernova lights, making for an incredibly capable do-it-all electric assist bike.

Also new in the commuter category is the Lacuba EVO E8, which features a Gates carbon belt drive, 8-speed internal Nexus hub, step-through frame design, suspension fork, and “walk assist” mode. With a Brose 250-watt motor equipped with a 650-watt hour power pack, the bike boasts a range of approximately 130 miles under optimal conditions.

On the off-road side is the E-Stream EVO 3 Carbon 27.5+ and Monster E FS fatbike, which bring some serious power to the trail with 250- and 350-watt motors respectively. The Monster boast a full suspension package to rival any trail bike, with 120mm of travel from a RockShox Monarch shock and Bluto fork.
