I've decided to get rid of my ZAP E-bike kit that I got new back in 1997, the motor still works like it was new, the tire roller shows a little bit of wear from the 1,000's of miles I put on it but should be good for 1,000's more miles, it's the DX model, so it has two motors and the speed controller is a set of relays that switch the motors from parallel to series to change from low speed to high speed, the battery still has just enough life in it to make it down the street and back, a new 12v 17amp hour battery would give it a 12 mile range at 15mph, I currently have it mounted on a low end Trek mouton bike with brand new road slick tires.
Sold! to a nice guy with 6 Geo Metros
