E-enduro bikes aren’t as different to regular bikes as one might imagine. All of the fundamentals are the same and by nailing the geometry and sizing Vitus has produced an amazing e-bike with the E-Sommet VR.Sure there are a couple of little things we’d probably change, like the STEPS Di2 mode shifter and rear tyre, but that’s about it. And given how much cheaper the Vitus is compared to the competition, you can easily afford to make these changes and even buy a spare battery. The E-Sommet VR is no golf buggy, but Vitus has it’s certainly hit a hole in one with this bike.
On the road, it takes only a few turns of the pedals to activate the Vado’s motor and get it up to speed. In Turbo mode — the bike’s highest level of pedal-assist — the Vado reaches speeds of up to 28 miles per hour, after which the electric drive system automatically shuts off to conserve power (and abide by local law). A built-in LED readout on the handlebars allows riders to monitor battery life, check current speed, and track calories burned while also being able to glance at distance traveled. The Turbo Vado Mission Control app (iOS/Android) also connects to the bike via Bluetooth and allows riders to further tune their ride and adjust the bike’s settings.
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.
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
The Spectral:ON is our most challenging development project to date. With the focus on the essentials, it was our clear goal to design an E-MTB that rides like the perfect trail bike. The result is already award-winning: modern trail geometry, wheel concept with 29/27.5" wheels front and rear, plus Shimano's powerful Steps E8000 drive. With the support of the engine, Spectral:ON expands your horizons: more trails per hour, trying out new ways and pushing the boundaries. You master even steep, technical climbs playfully and enjoy the agile handling and the outstanding smoothness in fast passages downhill. Space for bottle holder, geometry adjustment and lightning-fast battery change? Standard! We've taken every detail into account to give you the ultimate E-MTB driving experience.
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...
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.
Depending on local laws, many e-bikes (e.g., pedelecs) are legally classified as bicycles rather than mopeds or motorcycles. This exempts them from the more stringent laws regarding the certification and operation of more powerful two-wheelers which are often classed as electric motorcycles. E-bikes can also be defined separately and treated under distinct Electric bicycle laws.
