eRad mid-drive conversion kit

e-RAD mid-drive kits are the result of several years of effort to perfect a user-friendly, high-performance e-bike conversion kit. Unlike other systems, e-RAD drive systems can operate with both a throttle and/or pedal assist function (PAS). The throttle and PAS can be used independently giving the rider the choice on how best to use the motor’s power.

With 5 levels of PAS, the rider can choose the amount of assist that best fits the terrain and riding style. The throttle is active in all PAS modes and can be used for an extra amount of boost when needed.

We recently converted a Santana tandem bicycle into an electric bike with the e-RAD mid-drive system, and it turned this bike into a super-sonic, fun-riding machine. Now our customers, a husband and wife, continue to ride their magnificent bike up and down the hills in Brown County and all over the world (they love to travel with their bike). Plus, the system has such a nice sleek design that we were able to keep the bike looking clean and not full of wires and clunky controls.
