ABSTRACT:
An electrical bicycle comprises a frame body, a battery and a rotation controller. Characterized in that a driving mechanism is disposed at the rear triangle supporter and one side of the spindle. The transmission collar and fly-wheel are disposed at both ends of the spindle respectively. The transmission collar is rotated by means of the DC motor, the first and second bevel pinions. The output of the DC motor is reduced by the combination of the first and second bevel pinions. No chain is needed, consequently the defects inherited thereof are omitted. This electrical bicycle is free from noise and pollutant emissions. The driving mechanism can be switched on easily as necessary.
