As a serious,but aging cyclist, have been considering the purchase of an electric assist bike for some years. My primary concern was that the bike needed to provide enough power to assist me to tackle some very steep hills and my weight is near 220 lbs. Having no experience with electric assist, I anticipated the 500 watt motor rating of this ... full review


eMTBs appeal to an extremely broad target group: some use their eMTB for daily commuting, others for after-work or weekend rides on maintained gravel roads, and others plan to do an electrified alpine traverse or even an action-packed visit to the bike park. The good news is that many eMTBs are jacks of all trades, covering a very wide range of uses. Others, unfortunately, may disappoint with poor spec or nervous handling.

Before this test we thought more travel on an e-bike would obviously be better. After all, with the motor flattening out the climbs, why not have the extra suspension firepower to smooth out the descents? Sounds reasonable, doesn’t it? But in the case of the Specialized Turbo Kenevo Expert, the extra travel and weight make the bike less effective and less engaging on all but full-on downhill tracks. And if that’s your bread and butter, the Kenevo could well be the perfect topping. Here in the UK though, the Vitus proved more versatile, just as capable and way better value.
Weight isn’t anything like a critical as one would assume. Weight distribution however is a different matter and this is where geometry, specifically the ratio of the front centre measurement to the chain stay length really comes into play. Battery placement is important too, and smaller batteries give an edge in the handling stakes while robbing the bike of range.
Two years worth of research and development may seem like a long time for a mountain bike but when you take a closer look at what Rogue Ridge accomplished in that time period we’re confident you’ll appreciate the work. For instance, each offering hosts a best-in-class 1000-watt motor and 13 amp hour battery to help keep this electric fat bike at the ready whenever you are. Also, with said set of fat tires, any terrain from sand to mud; rocks to snow, is within your grasp. Additional features include a full-color digital display, a range of 29 miles without pedaling, and a tech welded 6061 aluminum alloy frame among many others.
X-Treme Scooters Folding Electric Mountain E-Bike offers a comfortable ride with front and rear suspension. It is an ideal bike for the college students, campers, and anyone who wants a portable and lightweight mode of transportation. This E-bike works on a motor of 300 watts. The best thing about this bike is it allows you to fold it after reaching the destination. It gives you a speed of about 20 mph with a 7-speed Shimano tourney gears. You can adjust the seat according to your ease.
In order to make the final judgement of every bike as objective as possible, the test team includes ex-racers and engineers as well as amateur riders and eMTB newbies. Even if we explored the bikes’ performance on the trail to the limit, we attach as much importance to their everyday usability. A potent and balanced bike which shines on demanding singletrack and is fun to ride should ride just as well on more moderate trails. And even if you’re not taking yourself and your bike to the limit every time you ride, it’s good to know that the bike is prepared for any situation you might feel like throwing at it.
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...

In response to customer questions about the display, we posted a video detailing the basic setup of the LCD during installation of the kit. You will need to adjust the settings for the motor type, wheel size, and battery voltage in order to match your specific kit.  Detailed instructions are available in the E-BikeKit manual, E-TrikeKit manual and LCD Quickstart Guide


With almost as many awards as technical features, it’s no secret why we opted to include HaiBike’s SDURO HardNice 4.0 in the list. First and foremost, this sleek aerodynamic ride doesn’t even initially come off as an electric mountain bike. That is until you experience first-hand the integrated Yamaha PW Drive Unit offering dynamic support and a top speed of 20 mph. Also, the bike features a shock-resistant skid plate that works to protect the motor from harm, and a Yamaha LED display that’s small yet robust and works to keep you informed on the bike’s status and functionality.
When did mountain biking get so uptight? As we see it, fun is a right, and no matter where or when you're riding, it should always be at the heart of each pedal stroke. So whether you're on singletrack, sand, or snow, the Fatboy will deliver a good time. It has tire clearance for up to five inches, a lightweight M4 aluminum frame, snappy handling, and rack mounts that make it adventure-ready, the question is, 'what's taken you so long?'
The box looked rough. Lots of little digs and dents. When I opened the box, the contents were very well packed. Mine did show that it took a good hit to the headset stem as the spacers where shoved and the clear tape was all bunched up and the one spacer was almost at the edge. After taking the tape off, cleaning all the tape residue off everything went together super easy. I used the included multi tool to do most of the assembly. I just needed a wrench for the peddles.

This is a question the designers and engineers of the FOCUS and BULLS bikes of this group test asked themselves. Instead of speccing them with the standard 500 Wh batteries, both have developed a sophisticated alternative. The idea: instead of riding around with unnecessarily large batteries and unnecessary weight on short tours, they integrated a smaller 375 Wh or 378 Wh battery into the bike. If you don’t have enough power for long loops, you can double the range of both bikes with an additional battery for up to a full 750 Wh. While the second battery is mounted in the front triangle of the FOCUS, it disappears sideways in the downtube of the BULLS. In practice, you’ll need the second battery relatively often with both bikes, and in either case, you should consider the additional € 499 investment in a second battery pack when you buy the bike.
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.
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.

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]
It’s always good news to hear a gasoline carmaker is continuing its electric mobility adventure, and what better way to do this than to stray from low-hanging fruits such as SUVs and pickup trucks. GM is no stranger to bold moves and we hope it will continue with the same determination to bring us more Volts, Bolts, and why not electric folding Jolts? (No, Jolts is not my personal entry for the $10,000 prize.)
After a couple years of strong antibiotics, a strict diet, and lots of rest, I was getting better so I thought I would try biking again. My son Andrew took me for a modest city ride and my Lyme symptoms spiked for three solid weeks – malaise, headaches, and weakness returned. I realized that I would probably never ride bikes again. After talking with my doctor and doing some research, I found that easy to moderate exercise can be beneficial, but strenuous activity can be detrimental. With mountain biking it is difficult to avoid exertion except with lift-assist or shuttles to trails with uninterrupted descents. Typical mountain bike rides with even slight hills like my city ride would probably send me into a tailspin again.
My left crank arm came loose and seems to have damaged the square bottom bracket mount. I assumed the bottom bracket was just a standard square taper, but noticed it says “8fun” on it. However, I can’t seem to find an 8fun bottom bracket available online, so I can’t figure out what part I need—I suspect there is a something obvious that I’m missing. Any ideas to get me back on the road? Thanks all.

Nicolas Zart Nicolas was born and raised around classic cars of the 1920s, but it wasn't until he drove an AC Propulsion eBox and a Tesla Roadster that the light went on. Eager to spread the news of that full torque, he was invited to write for various CleanTech outlets in 2007. Since then, his passion led to cover renewable energy, test drives, podcasts, shoot pictures, and film for various international outlets both in print and online. Nicolas offers an in-depth look at the e-mobility world through interviews and the many contacts he has forged in those industries. He particularly enjoys communicating about the new e-mobility technology and what it means to us as a society. Today he focuses most of his writing effort on CleanTechnica, a global online outlet that covers the world of electric vehicles and renewable energy. His favorite tagline is: "There are more solutions than obstacles."

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]
