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.
Range is a key consideration with e-bikes, and is affected by factors such as motor efficiency, battery capacity, efficiency of the driving electronics, aerodynamics, hills and weight of the bike and rider. Some manufacturers, such as the Canadian BionX or American Vintage Electric Bikes, have the option of using regenerative braking, the motor acts as a generator to slow the bike down prior to the brake pads engaging. This is useful for extending the range and the life of brake pads and wheel rims. There are also experiments using fuel cells. e.g. the PHB. Some experiments have also been undertaken with super capacitors to supplement or replace batteries for cars and some SUVS. E-bikes developed in Switzerland in the late 1980s for the Tour de Sol solar vehicle race came with solar charging stations but these were later fixed on roofs and connected so as to feed into the electric mains. The bicycles were then charged from the mains, as is common today. While ebike batteries were produced mainly by bigger companies in past, many small to medium companies have started using innovative new methods for creating more durable batteries. State of the art, custom built automated precision CNC spot welding machines created 18650 battery packs are commonly used among Do-it-yourself ebike makers.
While I was waiting patiently for my 2017 model eBike to be manufactured and delivered, I came across an article in the local paper about a woman with a degenerative muscle disease who wants to take her eBike on forest service trails that are designated for mountain bikes. “What the hell?” I said, completely floored (what I actually said isn’t fit for publication). When I ordered this bike, the thought hadn’t even crossed my mind that it would be illegal to ride on mountain bike trails with my new, albeit electric, mountain bike.
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.
Beach cruiser fans rejoice with the Raleigh Retroglide iE Step Thru. Cruise the boardwalk with maximum style and minimum effort as you enjoy the perks of a 350 watt motor and a top pedal-assisted speed of 20mph. Enjoy the comfort of an upright riding position thanks to the backswept handlebar and take advantage of the cargo-carrying capacity, thanks to the rear rack, to run errands around town or commute to work. With a claimed range of 35 miles, the Raleigh Retroglide is a great choice for anyone who wants to add a little speed to daily cruise.
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.
The Ancheer folding electric mountain bike does have a few weird quirks. The first is the handlebar mounted battery. It saves space for the folding mechanism, but looks odd. Fortunately it has very little effect on handling because it is mounted so close the head tube’s pivot point. It does raise the center of gravity of the bike a bit, but the difference is small compared to how much you raise the bike’s center of gravity.
It’s not as far-fetched as it sounds. In Europe, where the e-bike market has exploded, the European Cycling Union announced that it will create a new racing circuit for e-bikes, including e-road and e-mountain bikes, for the 2019 season. Following suit, the UCI said it will include an electric mountain bike competition in the 2019 World Mountain Bike Championships. Yes, there will be a rainbow jersey awarded to the world’s best off-road e-biker.

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.
Every major bike manufacturer—and literally dozens of smaller ones—is already in the e-bike game. Car companies aren’t far behind. Ford is already bankrolling an electric bike-share system in San Francisco, and plenty of others are eyeing up the e-bike market. “The car business is jumping in with both feet,” Benjamin says, “because they realize that cars in high-density urban areas, where more than half the human race lives, just aren’t working anymore.” With big transportation players like Uber looking into e-bikes, and cities searching for ways to relieve traffic congestion, programs may only continue to expand.
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.
I have cerebral palsy and have used a powerchair since I was three.... About a year and a half ago I applied for a grant from the Challenged Athlete Foundation for a handcycle. While I was waiting for letters to go out I worked out at the gym. I was talking to my trainer about handcycles. I explained that because all of the weight was behind the drive wheel in...
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.

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
Not all e-bikes take the form of conventional push-bikes with an incorporated motor, such as the Cytronex bicycles which use a small battery disguised as a water bottle. Some are designed to take the appearance of low capacity motorcycles, but smaller in size and consisting of an electric motor rather than a petrol engine. For example, the Sakura e-bike incorporates a 200 W motor found on standard e-bikes, but also includes plastic cladding, front and rear lights, and a speedometer. It is styled as a modern moped, and is often mistaken for one.

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.
The three bikes we tested all use a different e-bike motor system, and the controls, the primary user interface, are an important element that we rated but didn't weight as heavily as some of the others. Each motor system and their associated controls are different. Our primary interest is in how user-friendly is it to interact with the system, how intuitive and ergonomic are the shifters, how good and easy to read is the display, and how easy is it to charge the battery? Each drive system also has a smartphone app that is intended to allow the user to fine-tune the motor's support settings, create custom settings, monitor battery charge and health, and a whole lot more. While we don't feel the apps are necessary for the use of any of these e-MTB's, those with an affinity for technology or personalizing your ride may be inclined to use them.

As a household name, Specialized is to be trusted in this world without a doubt. That’s because, in addition to their inventory of pedal-powered machinery, they’ve gone ahead and introduced us to their S-Works Turbo. Here, in conjunction with their custom Trail-tuned motor for off-road use, the Levo FSR frame is constructed entirely of FACT 11m carbon fiber allowing for both a lightweight and stiff ride through the local wilderness. Additional features include instant engagement, heat management, and a silent output for good measure. Not bad Specialized. Not bad at all.
