On the descents, the Commencal felt somewhat one-dimensional, great when up to speed, but with sluggish and less nimble handling hindering its performance in tighter, low-speed technical sections of trail. The Meta Power Race also had the shortest distance range in our head to head testing, another factor which kept this contender off the top step of the podium. That being said, this e-bike was built for charging, no pun intended, so if you're an aggressive rider who lives for eye-watering descents, then this might be the e-MTB for you. Read the full review to find out more about the Commencal Meta Power Race 650B+.
By 1898 a rear-wheel drive electric bicycle, which used a driving belt along the outside edge of the wheel, was patented by Mathew J. Steffens. Also, the 1899 U.S. Patent 627,066 by John Schnepf depicted a rear-wheel friction “roller-wheel” style drive electric bicycle.[7] Schnepf's invention was later re-examined and expanded in 1969 by G.A. Wood Jr. with his U.S. Patent 3,431,994. Wood’s device used 4 fractional horsepower motors; connected through a series of gears.[8]
The Best in Test and Best Value tips do not result from the sum of star ratings, but by the assessment of the entire test team, taking into account the overall concept of the bike. It would be methodologically wrong to only add up the star ratings to make a final judgment in a scoring system – saying that something is “good” will not help anyone if they don’t know what it is for and for whom it is “good.” For this reason, we give a clear recommendation in every test result for which type of rider and purpose the bike is suitable and which not. The bikes themselves are as individual as the riders are – we just want to provide you with all the information you need to make a well-informed decision before buying. Here’s to long-lasting fun!
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.

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.


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...
Electric mountain bikes (eMTBs) are relatively new on the scene and mountain bikers are freaking out. “They shouldn’t be allowed on our trails.” “They are going to ruin the sport.” It reminds me of when the first mountain bikes started popping up on trails and hikers were panicking with visions of crazed bikers running them over. Well, their fears never materialized and mountain bikes have become popular tools for exploring the outdoors responsibly.
The new Stumpjumper is the ultimate trail bike. Seriously, the damn thing rides like it’s on rails. It’s the most versatile trail bike we’ve ever made. And yeah, we’re stoked about that, but we’re even more excited about how well it’s tuned to you. We’ve said goodbye to proprietary bullshit, focused on your needs, and made, what we feel, is the new benchmark in trail bikes.
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.
Because the power is applied through the chain and sprocket, power is typically limited to around 250–500 watts to protect against fast wear on the drivetrain. An electric mid-drive combined with an internal gear hub at the back hub may require care due to the lack of a clutch mechanism to soften the shock to the gears at the moment of re-engagement. A continuously variable transmission or a fully automatic internal gear hub may reduce the shocks due to the viscosity of oils used for liquid coupling instead of the mechanical couplings of the conventional internal gear hubs.

My second e-bike, and it is amazing. 40 miles range on full assist, 4 levels of torque sensor assist, one level cadence sensor assist, one level throttle only, 20 speed, forks have 120mm of range, and the 500 watt battery is very powerful. The seat was too hard, so I replaced it with a gel seat and installed a BodyFloat under the seat. Also installed a rack.
Enjoy the thrill of the ride without the struggle. Although it looks just like a normal mountain bike, as soon as you pedal you will feel the difference. The Gtech Mountain eBilke has an easy to read LCD display, to tell you exactly how much charge you’ve got remaining. Ride for up to 30 miles on a single charge. For adventurous riders tackling more challenging conditions, the range may be reduced to 10 miles per charge**.
In the geared motor, a small and lightweight motor spins very fast inside. The electric bike motor then uses a planetary reduction gear inside the motor to reduce the rpm to the correct speed for a bike wheel. Electric Bike Motor An electric bike motor on an electric bike can be any kind of electric motor. There have been some very creative home brew e bikes that used any motor...
China's experience, as the leading e-bike world market, has raised concerns about road traffic safety and several cities have considered banning them from bicycle lanes.[2] As the number of e-bikes increased and more powerful motors are used, capable of reaching up to 30 miles per hour (48 km/h), the number of traffic accidents have risen significantly in China. E-bike riders are more likely than a car driver to be killed or injured in a collision, and because e-bikers use conventional bicycle lanes they mix with slower-moving bicycles and pedestrians, increasing the risk of traffic collisions.[2]
However, if your friends are riding a bigger single battery pack, you’ll have to either choose to cut the ride short or conserve battery life while they run in turbo. If your local rides are short, fast blasts but you want to benefit from the ability to take on longer tours, the Sam2 could be for you. We love the Pro version, but it’s also available at a range of price points.

As the weather begins to drop and the snow starts to fall, it is increasingly important to know how to properly care for your electric bike and its Lithium-ion battery. It may be possible for some people to ride their bikes during the winter months, while others must pack them away until the warmer weather returns. Whether you plan to ride in the cold and snow or if you decide to...
When riding a normal bike through creek crossings, and rock gardens, I typically stop pedaling often to avoid pedal strikes, and to maneuver the bike. This approach is not compatible with the Turbo Levo’s weight. On it, continual pedaling was necessary, but the big tires and well-damped suspension enabled me to roll over obstacles I’d typically try to avoid, with the motor helping me power over them smoothly. To make this constant pedaling possible without pedal strikes, the bottom bracket is moved higher and Specialized has spec’d 170mm cranks that are a tad shorter than normal. 
“People are buying electric bicycles as a way to reduce car trips,” Benjamin says. The data backs him up: 28 percent of survey respondents said they bought an e-bike specifically to replace driving a car. And many other reasons buyers listed for wanting an e-bike—including carrying cargo and kids, avoiding parking and traffic, and environmental concerns—also indicate a desire to get out from behind the wheel. Plus, you don’t need to change clothes or clean up when you arrive at your destination, because you don’t have to work up as much of a sweat.
It's what's inside your motor that sets it apart from the rest. Quality parts and assembly We've written here before about how to choose a motor, the different types of motors, the performance differences between motors, etc. But today I want to show you what makes our motors different from other hub motors. Today, harry is replacing the axle on a customer's direct-drive motor. The bike was crashed and the...

China has experienced an explosive growth of sales of non-assisted e-bikes including scooter type, with annual sales jumping from 56,000 units in 1998 to over 21 million in 2008,[72] and reaching an estimated fleet of 120 million e-bikes in early 2010.[2][73] This boom was triggered by Chinese local governments' efforts to restrict motorcycles in city centers to avoid traffic disruption and accidents. By late 2009 motorcycles are banned or restricted in over ninety major Chinese cities.[72] Users began replacing traditional bicycles and motorcycles and e-bike became an alternative to commuting by car.[2] Nevertheless, road safety concerns continue as around 2,500 e-bike related deaths were registered in 2007.[73] By late 2009 ten cities had also banned or imposed restrictions on e-bikes on the same grounds as motorcycles. Among these cities were Guangzhou, Shenzhen, Changsha, Foshan, Changzhou, and Dongguang.[72][73]
No day or ride is the same. Monday could be morning park laps, while Saturday might mean a day in the woods. If this is familiar, you need a bike like the CrossTrail. It has a responsive, durable aluminum frame, while our Body Geometry Fit science and a Multi-Circuit Damping fork ensure comfort over any terrain. Put it all together, and you have a bike that's just as versatile as yourself.
The Moterra is Cannondale’s biggest and baddest e-mtb and just looking at this thing you can see that it’s built to withstand some wicked downhills and big drops. With 130mm of front and rear travel, paired up with 27.5-inch wheels and trail-grabbing 2.8-inch tires, along with a KS LEV Integra Dropper Post make this pedal-assist mountain bike a great option if you want to climb farther to shred longer, but don’t want to lug your bike uphill for ages. The 250w motor, placed slightly farther forward than most other bikes to optimize weight distribution and handling, will give you a nice boost so you can enjoy the ride up and not be too gassed when you get to the top. After all, it’s all about the ride down, right?
Assembly was pretty simple and straightforward, there are some videos online explaining it. Definitely important to know how to switch it on, though -- pressing the "M" button for two seconds with the key in the "on" position. Despite being a heavy bike, it's very quick and nimble. I ride about 15 miles per day and was able to get two trips out of it before charging, riding fast. My only complaints are the squeaky brakes, and the front fender. Said fender is a bit too close to the tire on the front wheel and doesn't mount very securely, so it kept making very loud noises as it would catch the tire whenever I went over a bump or had to brake hard. I just took it off for the time being.

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.
The first regularly produced device resembling the modern bicycle was unveiled in 1818. It was called the Dandy Horse. The two-wheeled ride-on Dandy Horse was the brainchild of German inventor Baron Karl Drais, and it featured a handle bar, a padded seat, and two inline wheels of nearly equal size. What it did not feature were pedals; this was a "running machine," thus its name in German, Laufmachine. The Dandy Horse saw only a flicker of popularity, and was largely an historical footnote within a handful of years, though its design is nearly mimicked in the child's balance bike of today.
What does this mean for anyone with Stark Drive that was backed with greater then a 250W motor? Quite simply, it means that as long as you have not modified Stark Drive in any way, and depending on your local countries regulations (if they differe with this EU Standard) you are now able to use your bike legally in your location no matter where you are in the EU.
If you really want to see the future take a look at the Fazua Evation, with a battery and motor this system weighs an incredible 4.7kg! The battery only has 250wh, but at 1.3kg you could easily carry a spare in a pack. The really interesting thing about this system though, is the motor and the battery can be removed from the frame, so you really do have two bikes in one.

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.
XB-300-SLA X-Treme Electric Mountain Bicycle is a great bike for the novice as it is easy to ride with simple steps. It is an affordable bike with high-quality features that work on a motor of 300 watts and offers a speed up to 20 MP on a single charge. It takes up to 4 hours to fully recharge the battery for the next use. The comfortable padded seat, 18-inch steel frame, 7-speed tourney gear, 24V lead acid battery, power assist system, and steel front forks are a few features that make it popular.
The suspension works, but there isn’t any true dampening. That means you’re just riding around on springs. On a real full suspension e-bike (i.e. a few thousand dollars) you get actual oil-dampened shocks. Those absorb bumps and dampen the shock. With springs, the bike bounces a few times after bumps, with the energy dissipating through the spring stretching and compressing.

It seems everyone prefers both Juiced and RadCity E-Bikes. I am having a tough time choosing between two. I currently have a mountain bike and want something new just to kick back and cruise around on. I will not be daily commuting, but will be riding weeknights and weekends, so comfort is key. It looks like both will have deals for Black Friday or Cyber Monday. $999 for the Juiced OceanCurrent and $1299 for the RadCity.
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.
Upper Dublin Township in Pennsylvania is initiating a pilot project to gauge the advantages of using electric bicycles. The e-bike, as they are more commonly known, will be used for police work and for the Township’s Sitewatch program, which patrols and monitors parkland and playing fields. The people behind the program believe the electric bike could prove to be a useful tool, giving police officers and parks personnel a clean,...
A 2008 market survey showed that the average distance traveled in the Netherlands by commuters on a standard bicycle is 6.3 kilometres (3.9 mi) while with an e-bike this distance increases to 9.8 kilometres (6.1 mi).[79] This survey also showed that e-bike ownership is particularly popular among people aged 65 and over, but limited among commuters. The e-bike is used in particular for recreational bicycle trips, shopping and errands.[79]
