While this set off some excitement among Tesla watchers who also love two-wheelers, it’s much more likely that any e-bike that emerges will be a limited production run, Tesla-branded bike built with one of many great e-bike companies in California. Like the Tesla carbon-fiber surfboard or the Boring Company Flamethrower, it would provide excellent press, be offered at a high price point, sell instantly and be even more good marketing for Tesla. It might be a folder designed for the Model S frunk or other niches on the Model 3 or X. On the other hand, e-bikes are becoming a high-volume, global business and Tesla is well positioned with global retail space, excellent access to batteries, and big factories to get around for its staff. There might be a permanent product in place. Regardless, a dozen e-bike manufacturer CEOs undoubtedly picked up their smart phones and tried to get through to Musk or his execs immediately to offer their services.
The electric bike revolution has officially crossed into the arena of off-road motorbikes. For those who prefer riding in nature, Cake introduced a product which not only respects the environment but other riders, as well. Cake’s Kalk is a silent off-road motorbike that releases no emissions into the atmosphere. Additionally, its electric motor means no gear changing or clutching — a silent motorbike that won’t detract from the experience of others. Perhaps the best part is Cake avoided any sacrifice in performance. The Kalk reaches speeds of fifty miles per hour and features three distinct driving modes: Discover, Explore, and Excite.
Bosch’s flagship mountain bike system uses a mini drive ring with internal gearing to send its power to the drivetrain. There’s some resistance in the system over 25km/h, but when you first press down on the pedals there’s an impressive surge of power, and it offers good support over a wide cadence range. Its size has an impact on the width of the cranks (the Q-factor) as well as the chainstay length of the frame, and it’s not the lightest system on the market at 4kg for the motor. On the other hand, Bosch is the most established player on the market, and its system has proven itself over many years.
All the models we tested are full suspension all mountain/trail bike models with relatively similar amounts of suspension travel, geometry, and wheel/tire size. The addition of a large battery and a small motor adds significant weight to an e-bike and they generally weigh in the neighborhood of 50 lbs, approximately 20 lbs heavier than non-e-bikes, and the massive weight of these bikes makes them more difficult to ride without the support of the pedal assist motor.

Yukon Trails Outback Electric Mountain Bike is an affordable urban bike with a 24 volt motor of 250 watts. The lead-acid battery of 10 AH offers 28 miles in a charge. This mountain bike is manufactured in China. The bike has the solid tires of 1.75 Watt and 24 inches. It reaches up to the speed of 15 MPH due to the rim of 24 inches. You can smoothly ride the bike while enjoying the fresh air. The seat is comfortable to sit for a long time.


REBEL electric bikes powered by the Yamaha central motor create Dynamic and Responsive Power. It also enables the use of a conventional groupset and offers no resistance in «no assistance» mode. The eMTB bikes range have an “External DT System” battery, located in the front triangle and integrated with the design of the frame. The relative position of the less lightweight parts of the system (motor and battery) enables a low center of gravity, guaranteeing a reactive and stable ebike.

The Haibike AllMtn line makes an appearance again with this incredible price-point option. The AllMtn 6.0 is a nice option with entry level components but the same aggressive build as the rest of the AllMtn line. And when I say entry level components, I definitely don’t mean that as a negative. You still get 150mm of travel with a Suntour Aion 35 RC suspension fork, a RockShox Deluxe RT rear shock, Magura MT32 hydraulic disc brakes, and Shimano Deore M6000 drivetrain with 20-speeds.
With most ebikes the choice of motor defines aspects of the frame geometry and to a lesser degree the suspension characteristics of the bike. Not with new Rock Mountain Altitude Powerplay. With its bespoke motor Rocky has been able to design an ebike that reflects the ride quality of a highly evolved 150mm trail bike. With instant power pickup, extended battery life and streamline proportions it’s not just the handling of the Rocky that will get you charged up for riding. It’s the best bike in this test by some margin, but we had an issue with the motor momentarily cutting and raising questions over it’s reliability.
E-bikes are classed according to the power that their electric motor can deliver and the control system, i.e., when and how the power from the motor is applied. Also the classification of e-bikes is complicated as much of the definition is due to legal reasons of what constitutes a bicycle and what constitutes a moped or motorcycle. As such, the classification of these e-bikes varies greatly across countries and local jurisdictions.
This bike is named the GSD because with it you can Get Stuff Done. Twenty-inch wheels keep the center of gravity low so heavy payloads—it's rated up to 400lbs—are easy to balance and a short (for a cargo bike) 70-inch wheelbase, similar to a standard single bike, make the GSD easy to maneuver. Designed with the urban commuter in mind, the bike can easily break down to 60 percent of its original size to fit into the back of a car and the rear rack doubles as a stand that allows it to stand upright to minimize space inside tight apartments. Put two child seats on the back and take the family along, or drop the seat and let you kid take the bike out himself—anyone from 4'10" to 6'5" can ride this bike. Last but not least, the GSD gives you the option of adding a second battery to extend your range up to about 150 miles on a single charge.

A letter from Casey Evans to Electric Bike Technologies, makers of the E-BikeKit™ electric bike conversion kit system. This one of kind adaptive electric stroller was designed by students from California State University-Sacramento using two 500w direct-drive hub motors controlled by a single E-BikeKit system. Thank you for enabling me to take my daughter hiking! My name is Casey Evans and my daughter, Montel, was born with a very rare...

Controllers for brushless motors: E-bikes require high initial torque and therefore models that use brushless motors typically have Hall sensor commutation for speed and angle measurement. An electronic controller provides assistance as a function of the sensor inputs, the vehicle speed and the required force. The controllers generally allow input by means of potentiometer or Hall Effect twist grip (or thumb-operated lever throttle), closed-loop speed control for precise speed regulation, protection logic for over-voltage, over-current and thermal protection. Bikes with a pedal assist function typically have a disc on the crank shaft featuring a ring of magnets coupled with a Hall sensor giving rise to a series of pulses, the frequency of which is proportional to pedaling speed. The controller uses pulse width modulation to regulate the power to the motor. Sometimes support is provided for regenerative braking but infrequent braking and the low mass of bicycles limits recovered energy. An implementation is described in an application note for a 200 W, 24 V Brushless DC (BLDC) motor.[43]
The LT or long travel line that Haibike is one of the most interesting developments in electric mountain biking in quite some time. I’ve chosen the FullSeven LT 4.0 because I wanted to show you another quality, low-cost option. The FullSeven line is built a little less aggressively than the AllMtn series, but still functions as a great all-around mountain bike for those riders who want to hit fire roads, and maybe the occasional single-track trail. The coolest thing about the LT line is that it costs exactly the same as the standard FullSeven line that comes with 120mm of travel. You can upgrade to 150mm on any FullSeven bike for no extra cost.
If you haven’t ridden or even seen a modern eMTB, here is what I have discovered. They are sturdy rigs that come standard with quality mountain bike components including beefy forks and rear suspension systems, strong disk brakes, and a reliable drivetrain. They are heavy but not that far out of the old downhill bike weight class. The distinguishing “e” features are the electric motor at the bottom bracket (some have hub motors), the battery pack, and the handlebar-mounted computer that controls the system. They have adjustable assist modes: off, low (barely helps), medium, and the battery-draining high mode. When everything is put together, they are something to behold.

Cargo bikes and city bikes are common in the e-bike space, but until recently we haven’t seen that many performance road bikes. The Giant Road E+1 is a pedal-assist performance road bike that’s made for more than just commuting; the powerful motor can rank you up to 28mph very quickly on the highest setting so you can rip the flats, join your local group ride, or blast through the mountains with far less effort than a traditional road bike. Don't expect it to feel like a 16lb race bike when you lean it into high-speed turns, but the endurance-oriented geometry allows for an aggressive position on the bike and keeps the it nimble and agile at high speed.
The frame itself incorporates a series of mounts allowing you to easily trick-out the Road E+1 with a rack, fenders, or panniers to more aptly meet your touring requirements. Again, most touring purists will certainly scoff at the mere notion of pedal-assistance, however, individuals looking for more of a guided tour and less of a tour de force will swoon over the Road E+1.
Power delivery is smooth and easy to predict, once you get the hang of it. We’re not sure if integration is better on the Turbo road bike, or if the slow, technical nature of trail riding just highlights some quirks. The motor shuts off less than a second after you stop pedaling, and the onset of power delivery is momentarily delayed once you begin pedaling. And this did mean we had to adapt our riding style a little bit to deal with that slight lag. 

Basically, there is no reason to ride an eMTB with less than 130 mm of travel. With classic bikes, more travel usually means both less efficiency and poorer climbing characteristics, but this is not true with eMTBs – at least not up to a certain point. The best example is the Specialized Turbo Levo, which with its 135 mm of travel at the rear handles much better than most of the other, longer travel bikes in the group test. Also, eMTBs with suspension travel of 180 mm or more are often noticeably less efficient, as clearly exemplified in this test by the Haibike XDURO Nduro. It climbs a lot slower than other bikes using the same motor and the same level of assistance, an experience you will find with almost all other long-travel bikes from other manufacturers. The exception is the BULLS E-CORE EVO EN Di2: in direct comparison, it climbs a lot more efficiently, even though it also offers 180 mm of travel. The ideal compromise between uphill and downhill performance usually lies somewhere between 130 and 160 mm of travel.


As electric bike options continue to expand, more brands are integrating the battery more seamlessly. That makes them look sleeker (and more like a real bike). Batteries are expensive, so make sure there's a good way lock the battery to your bike if you'll be keeping it outside. Overall weight is important. Some battery and motors can add 15 pounds or more to the bike. With assist, you won't feel that much when you're riding, but you will if you have to carry your bike up stairs or lift it onto a bike rack.
Whether you're riding in the backcountry or racing enduro, you need a bike that's capable and efficient. After all, to ride 'all mountain' necessitates riding the entire mountain. That's why our Enduro line of all mountain bikes, both in 650b and 29er options, come equipped with loads of travel, lightweight constructions, and geometries that can handle themselves on anything from downhill tracks to stomach-wrenching climbs.
There’s a feeling people get when everything just clicks on a ride, and the Roll is a bike that pulls it all together for you. Take it on a bike path and enjoy the smooth ride afforded by a lightweight frame and Ground Control Positioning. Feel the confidence a wider, more stable tire provides. And ride longer with the Body Geometry science that’s gone into the saddles, grips, and pedals. Get out there, get active, and feel it for yourself.

For those who know the brand, Ducati makes lust-inspiring road motorcycles, covering the range from scramblers to naked bikes to sport bikes. They’ve topped podiums globally, appeared in too many movies to name, and in some cases have ended on display in art galleries. But like everyone in the motorcycle business, the company is challenged by global changes and is looking to capitalize on its valuable brand. Likely it was challenged to by its corporate overlords, as the Ducati company was acquired by Audi and hence VW in 2012.


We rode the Vado through the gauntlet, including some of the steepest hills in Palo Alto, and it easily handled everything we threw at it, maintaining a steady 20 miles per hour even on the most daunting of ascents. The bike also handles well on downhills and is both nimble and quick on city streets and paved trails. It’s even comfortable to ride for extended distances, which is vitally important for any bike built for urban settings.
