Abstract
A unique drive transfer device for use with personal electric vehicles, such as bicycles and scooters. In particular, a cordless, battery-driven rotary hand held tool is mounted to the vehicle in a manner whereby the rotatable output shaft of the tool is coupled to the rear wheel of the vehicle to drive the vehicle. The tool is powered by one or more batteries, a battery pack being mounted to the vehicle. The tool output shaft provides torque on demand and is sufficient to drive the vehicle over a wide range of speeds.
