Claims

[Claims for Utility Model Registration] (1) In a bicycle in which the rear wheel is chain driven by the rotation of the crankshaft, a sprocket is connected to the crankshaft by a unidirectional bearing, and the rotating shaft of the motor is connected to a power source. A small gear is connected to the worm and the worm gear through the worm and the worm gear, and this small gear is engaged with the sprocket to transmit the rotation of the motor to the sprocket.
An electric bicycle characterized in that it has a built-in variable resistor that can be varied with a lever, and is equipped with a speed controller that controls the amount of current to the motor and continuously changes the speed of the rotation of a sprocket. (2) The electric bicycle according to claim 1, characterized in that it is equipped with a sunlight concentrating board, converts sunlight into electricity and charges it into a storage battery, which serves as a power source.
