Hi, I am Jonathan Smith. There are loads of reasons to install an electric bike conversion kit to your current bike, but the question of whether it's worth doing is going to depend on your circumstances. For rear installations, the motor is more discretely buried with the cogs and pannier bags, and it is possible to run at very high power levels without losing traction. And secondly, to harness your power output for battery charging would need to remove it from propelling the bike, which would completely alter the feeling of the ride, as your power output would be disconnected from forward propulsion. For the best experience on our site, be sure to turn on Javascript in your browser. Heres how it works. eZee Kit: The eZee system is our popular high performance geared motor setup, and has about twice the power and torque capability of the Bafang G31X motor (500-1000 watts), making it better suited for steeper climbs and cargo hauling. While it is sometimes touted as an important safety feature, in practice we don't think these are generally necessary for that reason. Wheel size: Wheel: Bulk savings: Buy 1. With the increased number of people riding e-bikes, riders are now thinking in a more independent way about managing battery capacity and range and at a certain point, that thought experiment turns to power regeneration and the question of whether electric bikes charge when you pedal. Wiring and Connector These motor cable exits the end of the axle and extends 22cm to an overmolded Z910 connector terminal. We've tested as many as we can ourselves in real-world riding conditions, worked out how easy they are to fit, and what kind of electric assistance they provide.

Taxes and shipping calculated at checkout. This has enormous advantages in terms of simplicity with no moving parts inside, but in order to achieve adequate torque the direct drive motors need to be fairly large in diameter and heavy. This helps to extend the range of the bike and makes it more efficient overall. This is complete nonsense, and in fact for most conversions we recommend a front hub unless there is a compelling reason to put the motor on the rear. The combined mass of a bike and rider is just too low, to generate adequate kinetic energy when braking. The ~4kg motor is available in both front and rear options, and comes prelaced in 20, 26, and 700c wheels with a Schwalbe Marathon Plus tire too. But what if there was a way to capture that wasted energy and use it to power your bike? Firstly, it would be much less efficient to attempt to turn the power generated by your legs into battery power to then be used for forward motion later. It uses a cassette freehub system and has a power and torque output that comes close to that of the eZee hub motors. Larger vehicles have a better regenerative braking coefficient. With the mass of a train or car, you have a much greater energy conversion through the braking system. The combined mass of a bike and rider is just too low, to generate adequate kinetic energy when braking.
