On the AM 4 you get 150mm of travel via a Fox Factory 36 Float fork, 11-speeds from a Shimano Deore XT drivetrain, and Magura MT-Trail hydraulic disc brakes. They also don’t gip you on the dropper with a wonderful, wonderful KS Lev. In terms of geometry, the build is pretty dope. It’s a nice slack feel, so you can do some solid downhills. A DT Swiss wheelset along with Magic Mary tires give you a lightweight and smooth ride.
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.
Pedelecs are much like conventional bicycles in use and function — the electric motor only provides assistance, for example, when the rider is climbing or struggling against a headwind. Pedelecs are therefore especially useful for people in hilly areas where riding a bike would prove too strenuous for many to consider taking up cycling as a daily means of transport. They are also useful for riders who more generally need some assistance, e.g. for people with heart, leg muscle or knee joint issues.
The Super Commuter is very aptly named. The 350w Bosch motor will help you sustain speeds of up to 28mph, and the burly, 2.4-inch wide, Schwalbe Super Moto-X 650b tires will keep you secure on even the roughest city streets, and Shimano Deore hydraulic brakes provide ample stopping power. Fenders provide welcome protection from road spray so you arrive at your destination fresh, integrated lights are critical for post-sunset riding, and a side-view mirror hanging on the left side of the handlebar gives a great view of traffic around you. After all, you can ride at the speed of urban traffic on the Super Commuter.
Ethics aside, that’s not to say we don’t at least admire where the technology has taken us thus far – and where it appears to be heading- thanks to some of the best electric mountain bikes on the market today. Some, naturally, are more rugged and built to withstand greater beatings than others. While some feature a price tag similar to that of a new Harley-Davidson. Whatever the case, if the disposable income is there, as well as the integrity not to abuse the power these electric machines offer, then they’re certainly yours for the taking. Just have a look at our eight favorite picks below and see for yourself.
E-bikes remain a subject of controversy in mountain biking circles. You may not be able to take one on your favorite singletrack right now, as most non-motorized trails prohibit them. However, things have been tilting in a more permissive direction. Most recently, IMBA, the sport’s largest public advocacy group, shifted its stance to support allowing access for some pedal-assist e-bikes (those that top out at 20 mph) on some trails. With every major manufacturer making e-mountain bikes, more access is likely only a matter of time. “In a few years, people will realize that electric mountain bikes have no more trail impact than a regular mountain bike,” Benjamin says.
Introducing a fully integrated, electric-assist mountain bike that takes our Altitude’s legendary handling and ride quality and adds a compact, powerful drive system. The new Powerplay™ drive system was designed in parallel with the frame, delivering ultra-short chainstays, optimised suspension kinematics, super-low centre of gravity, and class-leading torque. The result is an e-MTB that actually rides like a proper mountain bike—perfect for everything from self-shuttling all mountain trails, finding flow between the descents, and squeezing in power lunch rides.

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.
The quality of electric mountain bikes is changing dramatically. We set out to find the best ones you can buy today. After looking at 15 models, we narrowed it down to four in the $5,000-$5,500 price range. We then took to the trails. Over the course of several months, our team of testers rode these e-MTB's for thousands of miles and hundreds of hours to find out how each model performs on the trail, which one has the longest range, the most power, and most user-friendly controls. We rode these bikes hard, scrutinizing every aspect of their performance, exposing the strengths and weaknesses of each. We present our findings here in this detailed comparative review to help you find the model that's right for you.
Whether you need a bike to help you stay fit and active, or you just want something comfortable to get around town on, we have a hybrid bike that's tailor made for however and wherever you ride. Each bike represents an intuitive design that's purpose-built for the task at hand. So get out and get exercising, rolling through woods, commuting—whatever. All that we care about is that you're having the time of your life on the perfect bike.
Bottom Line The Specialized Turbo Levo FSR Comp 6Fattie was the most well rounded bike in our test, the winner of our Editor's Choice Award. Commencal's first foray into the e-bike market was worth the wait with a hard charging ride that utilizes their Meta frame design and Shimano's E8000 motor. The HaiBike XDURO AllMtn features a powerful pedal assist motor, but in a less refined package. The Trek Powerfly 7 FS is a good electric mountain bike, but its component specification is holding it back from reaching its potential.
Some power-on-demand only e-bikes can hardly be confused with, let alone categorised as, bicycles. For example, the Noped is a term used by the Ministry of Transportation of Ontario for e-bikes which do not have pedals or in which the pedals have been removed from their motorised bicycle. These are better categorised as electric mopeds or electric motorcycles.
