High Current Batteries that are NOT LiPo

High performance requires high amps, but LiPo batteries can be dangerous for someone who is inexperienced with them. LiPo is capable of putting out VERY high current (the C-rate), and if you are building a racing E-bike, they are simply the best choice. A LiPo pack will be smaller, lighter, and will put out more peak and continuous amps than any other pack you can buy. The problem is that…for E-bikers who want something that is much safer, but has better performance

DIY Mid drive builds, the why and the how, part-2

Written by Ron/Spinningmagnets, March 2013 The reasons why someone would want a non-hub build…in spite of the complexity, noisy drive components, and extra cost…was discussed in Part-1. Here, in Part-2…you have decided that you want a non-hub drive system, and you want to know what components others have used with some record of success. The two systems I’ll describe here are…first: a VERY high powered “one-speed” system that drives the left side of the rear wheel (leaving the stock right-side

Torque Arms on Hub Motor Bikes

This is a special concern when running a hub motor on the front, because if your fork snaps, it can have potentially fatal consequences (think face plant onto the concrete). There have been electric bike riders who have died this way so use extreme caution. The more powerful the motor the greater the danger. If you’re running a 350W Cute geared  motor,
