Fast and fun on the trail, the SDURO HardNine handles rough terrain with ease, while its large tires roll over most obstacles without missing a beat. The pedal assist makes for quick, energy-saving climbing and the bike descends surprisingly well, too. Its front suspension provides a nice level of cushion on bumpy trails and while we missed having a full-suspension on this model, that would have added additional weight and costs.
The harder you pedal, the bigger the boost, the faster you’ll ride—to a point. E-bikes let you hum along at a brisk clip, but they aren’t motorcycles. You’ll never jackhammer down the road at 45 mph. The motor is governed to stop propelling you further when you hit 20-28 mph, depending on the bike. So you’ll save time on your commute (I shave about three minutes off a five-mile trip) but still enjoy the scenery.
With 170mm travel, aggressive angles and Shimano’s superbly calibrated STEPS motor, the Focus Sam2 is an enduro bike with a built-in shuttle. With the bolt on TEC pack you really can climb to new heights, but without it the smaller capacity internal battery means you need to be ultra economical with your energy use. It’s also frustrating that the internal battery can’t be removed easily for charging. By far the biggest frustration with the Jam2 though is that the sizing isn’t very generous and standover clearance is limited. It’s still a great e-bike, but when you’re spending this much money, you can afford to be fussy.
There are various kinds and classifications of electric bikes on the market, but the more common type is the Class 1, or pedal assist, bikes which have motor units that are activated by pedaling and are limited to lower speeds. In the US, Class 1 electric bikes, the type tested and reviewed here, are limited to a top speed of 20 mph and their motors are designed with a speed governor to regulate this. These types of e-bikes resemble modern mountain bikes, but they have significant battery packs and small motor units integrated onto and into the frame design. The e-MTB pedal-assist motor is typically built around the bottom bracket and provides varying levels of pedaling "support" directly into the drivetrain while the cranks are turning. Most drive unit systems offer several support settings that provide pedal assistance between 25% and 100% of the user's pedaling input.

Controllers for brushed motors: Brushed motors are also used in e-bikes but are becoming less common due to their intrinsic lower efficiency. Controllers for brushed motors however are much simpler and cheaper due to the fact they don't require hall sensor feedback and are typically designed to be open-loop controllers. Some controllers can handle multiple voltages.
Even if you’re in excellent shape and very fit, you still can get exercise by e-biking. When I did a head-to-head comparison of commuting with my cross bike versus a recreational e-bike, I found that my relative effort was much lower, and I burned about half as many calories, on the e-bike. But I still burned something—up to 200 calories per hour, the equivalent of what you burn by walking. And I opted for quick e-bike rides to town where I would usually drive, which means I was considerably more active overall.

This isn't just the lightest mountain bike frame we've ever made, it's our lightest frame—period. The Men's Epic Hardtail was redesigned from the ground-up to give you an unparalleled performance advantage on the XC track. It flies up hills with ease, sends descents with confidence, and wastes nary a watt. Consider it a cross country revolution, and remember, this is going to be epic.


Older Americans, especially those 65+ are the real drivers of electric bike adoption in the United States. Betty and Grady Smith of Beaumont Texas may not know it but they are the driving demographic for electric bicycles and  tricycles. Both in thier eighties, the couple enjoys riding thier Worksman electric side-by-side tricycle around town. As a business offering electric bike and trike conversion systems since 2008, we've gotten to know...

Motor: We have a blog post showing some motor differences: https://www.ebikekit.com/blogs/news/its-whats-inside-your-motor-that-counts Cabling is probably the #1 issue when something goes wrong. Good connectors, good cables, and good assembly (bike shop!) are crucial Strain reliefs on all cable joints! Where you have a junction box or a connector, the stress is concentrated over a small area near this stiff spot on the cable. This can cause small breaks on the internal...
When all was said and done, the Commencal Meta Power Race 650B+ proved to have everyone's favorite e-bike controls. Commencal uses the Shimano Steps E8000 motor and system which features ergonomic thumb shifters, a small but easy to read digital display and a secure and straightforward charging connection. The ergonomic shifter of the Shimano system is better than the electronic buttons found on both the Specialized, HaiBike and Trek. The Commencal's best-in-the-test digital display also proved to be a favorite for its small size and out of the way mounting location, easy to read at-a-glance information, and color-coded support settings information. The HaiBike's Yamaha PW-X motor and system also featured a digital display, but testers thought it was a little too big, displayed too much information, was more challenging to read, and generally felt a little more clunky and less refined than the Shimano system. That Trek Powerfly's Bosch Purion shifter and display unit was easy to read and had a bright screen, but was in a less visible location on the left side of the handlebar. Our Editor's Choice Award winner, the Specialized Turbo Levo FSR Comp 6Fattie scored the lowest in this rating due to the lack of a handlebar mounted display and a less user-friendly charging connection.
You can’t really get a cheap e-bike just yet. But if you keep the car in the garage more often, you’ll save cash on maintenance and gas money. Not to mention the added health benefits and potentially fewer sick days from getting more exercise. Prices vary widely, but you should expect to pay at least $1,500 for a decent e-bike, and considerably more ($2,500-$5,500) for a quality bike with a motor system from a major manufacturer like Bosch, Shimano, or Yamaha.
The environmental effects involved in recharging the batteries can of course be reduced. The small size of the battery pack on an e-bike, relative to the larger pack used in an electric car, makes them very good candidates for charging via solar power or other renewable energy resources. Sanyo capitalized on this benefit when it set up "solar parking lots", in which e-bike riders can charge their vehicles while parked under photovoltaic panels.[66]
All models of the Turbo Levo use a frame made from M5 aluminum alloy, with the motor and removable battery integrated inside. The frame and fork use 148mm (rear) and 110mm (front) spacing. Specialized 6Fattie Purgatory (front) and Ground Control (rear) 3-inch wide tires are laced to 38mm Roval Traverse rims. Rear stays and pivots are beefed up to handle the additional weight (48.5 lbs) and torque, and bridges are added to the stays, over the non-motorized Stumpjumper. The front fork is a RockShox Yari XC with a 15mm thru-axle. The 135mm rear travel is provided by a custom Fox Float Performance DPS shock with automatic sag adjust. 
I saw an early version of the Carbo and was impressed. Although it looked thin and flimsy — the entire frame looks like you can bend it on a bad curb — it was very resilient and withstood my urban abuse. There are multiple modes, including Sport, which takes you almost immediately up to about 20 miles an hour with pedal assist, a great feeling. The battery is hidden inside the seat post and can be swapped out.
Direct-sales German brand Canyon’s entry into the e-MTB market came with a bang. The Spectral:ON is a stunning bike with a superb build kit, decent geometry and respectable weight (21.2KG listed weight). As with anything Canyon, it’s hard to find better value for money. The entry-level 6.0 is down there with the lowest-cost serious e-MTBs available, yet its build kit, including RockShox Yari fork, Schwalbe Magic Mary tyres and Shimano Deore XT derailleur, ensures the bike punches well above its price.
After 2 months of online research and talking to people that owned e-bikes I walked into the Glendale, Arizona Pedego store. I met the owners Sherry and Steve. They suggested I try the Ridge Rider as it might be a fit for me. I test rode it for about 45 minutes to an hour and was somewhat convinced this could be the bike for me. I went home and did more research on the Ridge Rider. After careful thought I decided to purchase one the next day. Since then Steve, the owner, has worked with me to personalize my bike so that it is as comfortable on the trails as it is on the road. I cannot say enough about the after sale experience I have received from Sherry and Steve. I would recommend them and their store to anyone interested in an e-bike.
The Shiv TT boasts an aerodynamic frame that observes the letter, but not the spirit, of the UCI's laws on position and frame shapes. Its profile has been refined in our Win Tunnel to take crosswinds in stride, and the wide range of fit options in the integrated cockpit lets riders find a fast, comfortable position for putting out power. Impressively, this is done without causing time-eating instability in tight corners or on technical descents.

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.
The time or distance an electric bike battery will run between chargings is impossible to judge with much accuracy. There are too many variables: terrain, speed, rider weight, bike load (shopping, kids, luggage), and more. However, we can make a few generalizations about an e-bike’s recharge time and overall working life. These generalizations should be used for comparison purposes only.

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.


The need to develop a high-performance e mountain bike provoked the launch of the ATOM X project over three years ago. A team of experts was put together from the fields of MTB geometry, suspension and performance, advanced motor, battery and IT technologies. That is how the innovative and patented “X System” came about, which represented an integration that was both ergonomic and different. It was developed until it became the best eMTB with the best of both worlds: high performance and the most advanced electric technology. See the ATOM X e mountain bikes...
