Bricklin and Currie formed the Electric Bicycle Company, and produced the first EV Warriors by late 1993. The electric bike was initially built using a custom aluminum mountain bike frame from Zimmark Corporation in Malaysia. Later versions used a Giant frame produced in Taiwan. All versions used a 6-speed Shimano rear derailleur with GripShift handlebar controller. The rider could pedal unaided by the motors, or could activate them with a thumb switch on the handle bar. That smoothly, quietly and quickly took the bike to 15-20 MPH depending on the size of the rider with a range of about 17 miles before it needed a charge.
