Duke Eco-Marathon Team using an Electric Bike Technologies hub motor for the 2014 Shell Eco-marathon. The E-BikeKit motor provides optimal space saving because it does not require a chain (this makes it great for converting road bicycles to electric bicycles, which is what it is designed to do) but we hope to determine if it provides us with a better overall vehicle efficiency than our outboard motor.
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.
So i am 15 years old. I drive to school every single day and go to the gym about 4 times a week. My bike is starting to let me down, and in march i will be 16. I want to go immeadietly for my driver license when i can, so i don’t want to study for so long and get my scooter license and pay a couple of thousand to get one, just to do it all over when i go for my driver license. Do you advise me to get my Ebike now? Or wait until i can get my scooter? And if i should get it, do you advise i build my own? I hear it’s like a pc, since you can get the performance of a 2000 dollar ebike with a 600-800 dollar bike you build yourself. Can Anyone advise me on these grounds?
A carbon frame shaves off several hundred grams of weight, of course. However, this is largely irrelevant when it comes to eMTBing. The two major advantages of carbon on eMTBs are, on the one hand, greater freedom in optimising the frame design and, on the other hand, increased stiffness. Thanks to carbon, smooth transitions can be achieved, better facilitating the integration of motor and battery. Unfortunately, the magical black material also has a few potential disadvantages. Carbon has poorer thermal conductivity, which means that heat is dissipated less efficiently with a fully integrated motor, and stiffer is not necessarily always better. Frames and wheels require a certain amount of flex to be comfortable and to generate enough traction through curves. Buying a carbon eMTB can currently only be justified by aesthetics rather than functionality.

The innovation isolation system, designed here in Washington, greatly enhances the endurance and enjoyment of riding a bike. Engineered to be infinitely tunable to fit your personal riding style and weight, Seattle Electric Bike is proud to offer this breakthrough seatpost for all your biking adventures.
One of the biggest drawbacks to any ebike is its range — and perhaps to a larger extent, the capacity of its compatible battery. Since battery technology innovation is fairly stagnant, the German ebike company Riese and Muller decided that instead of making a bigger battery, it’d just slap a second one onto its latest release, the Delite nuvinci. Though the attachment does add more to the final price (to the tune of $823), it also increases the Delite nuvinci’s range to a whopping 130 miles — which is leaps and bounds further than any other ebike on this list.
Mountain bikes have come a long way since the 80s. Rock Shox showed up and eventually everyone had a hardtail bike. Then came dual-suspension bikes for all sorts of riding styles. My choice was a cross-country bike so I could climb fast and descend fast without the need for big air. Brakes have gone from simple calipers, to grippy Shimano V-Brakes, to bomber hydraulic disk brakes. While all this was going on street-focused eBikes were evolving too. It should be no shock that the technologies would merge to create eMTBs. A lot of people who were part of the mountain biking revolution in the 80s are getting older and eBikes allow them to continue the sport they love later in life. Whether it’s riders dealing with health issues or injuries, or simply just getting older, the emergence of eMTBs makes total sense.
**The eBike uses a quick-release battery system. Lightweight 200Wh Lithium-ion battery packs can be swapped in seconds at the roadside. Each pack weighs just 1.4Kg, so spare battery packs can easily be carried for longer trips. The range that can be achieved from each pack will vary according to the conditions and effort exerted by the rider. Ranges of around 30 miles are normal per each full eBike battery charge. Less fit riders may achieve ranges of 10 miles or less, particularly in challenging conditions like steep hills, strong head-winds or soft terrain. The conditions which affect the range are rider fitness, weight, size and seating position, head or tail winds, gradient, terrain, tyre pressure, what gear is used, number of stop/starts and the speed the bike is ridden.
Rarely does one have a retail experience this favorable. First, the product is first rate. I can’t say enough about the Pedego Ridge Rider I bought, just an amazing e-bike at this price point. Second, to have customer service that is also outstanding is just amazing. The owners are genuine, knowledgable, and do everything in their power to give the customer a positive experience. Third, try an electric bike by Pedego, they’re truly an amazing experience.
I always felt GM should have taken a similar strategy as IBM did. Get rid of the manufacturing and focus on the service. In IBM’s case, it was a logical choice. But for a carmaker, switching to service only is foreign territory. GM has a lot of might in its manufacturing power and its global presence, now streamlined to a few brands. However, most of its sales are still gasoline SUVs, CUVs, and pickup trucks, as with other major OEMs. How much is it really focusing on its electric mobility path, including the addition of folding electric bicycles?
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.
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.
Forward-thinking parents are giving up thier SUVs and opting for electric cargo bikes for getting the family around. Cargo bikes are seeing a resurgence in popularity with the rise of electric conversion systems that convert these awesome people movers into family toting electric vehicles. One year ago the Wall Street Journal ran a full page article in their weekend edition entitled The New Station Wagon. Since then the trend for...
The environmental credentials of e-bikes, and electric / human powered hybrids generally, have led some municipal authorities to use them, such as Little Rock, Arkansas with their Wavecrest electric power-assisted bicycles or Cloverdale, California police with Zap e-bikes. China’s e-bike manufacturers, such as Xinri, are now partnering with universities in a bid to improve their technology in line with international environmental standards, backed by the Chinese government who is keen to improve the export potential of the Chinese manufactured e-bikes.
Torque sensors and power controls were developed in the late 1990s. For example, Takada Yutky of Japan filed a patent in 1997 for such a device. In 1992 Vector Services Limited offered and sold an e-bike dubbed Zike. The bicycle included NiCd batteries that were built into a frame member and included an 850 g permanent-magnet motor. Despite the Zike, in 1992 hardly any commercial e-bikes were available.
