A FACILITATED ELECTRICALLY DRIVEN BICYCLE
Document Type and Number:
WIPO Patent Application WO/2004/089735
Kind Code:
A1
Abstract:
A facilitated electrically driven bicycle comprises a frame, a pair of wheels, which is consisted of a front wheel and a rear wheel, a handlebar, a motor, a driving device and a control device. It is chazactcrised in that: said motor is a disc type motor, which is mounted to the inner side of rear fork of said frame. Said driving device is a gear driving device and comprises a small gear which is mounted to the shaft of said motor, a big gear which is mounted to the inner side of one side of said wheel, and said small gear is engaged with said big gear. According to the facilitated electrically driven bicycle of the invention, the power which is reduced by the small gear and the big gear is transfered from the motor to a wheel to rotate the wheel directly, so effective transmission is achieved, cost and weight is reduced. The used wire winding disc type permanent magnet motor is very light and thin, and the permanent magnet is made by incising a disc type magnet, and the manufacture is easy. Advantageously, compared with the conventional bicycle and electrically driven bicycle, the facilitated electrically driven bicycle of the invention has light weight, and it's center of gravity is lower, and it is multipurpose, and it's taking is easy and so on.
