An electric bicycle is provided which includes a sprocket wheel defining an inner ring and an outer ring with the inner ring having a plurality of tooth members extending therefrom. A power drive mechanism for electrically actuating the electric bicycle is included with the power drive mechanism including a motor rotatively coupled to a set of reduction gear members. The reduction gear members are coupled to a main bevel gear with the main bevel gear matingly engaging a direction changing bevel gear and a first balance bevel gear on opposing sides thereof. The direction changing bevel gear matingly engages the main bevel gear and a second balance bevel gear on opposing sides thereof. A clutch is mounted on a shaft member passing centrally through the direction changing bevel gears and a first balance bevel gear. The clutch includes a plurality of ball bearings rotatively mounted in an outer raceway of the clutch. A transmission gear is fixedly secured to the shaft member for engaging the tooth members of the sprocket wheel inner ring. A mechanism for electrically powering the electric bicycle is provided with the electrical power mechanism including a battery and a solar cell. The solar cell and the battery are electrically coupled to each other. A speed control mechanism is further provided which includes a rotatably actuated variable resistor electrically coupled to the electricl power mechanism of the electric bicycle. The rotatably actuated variable resistor is secured within a speed changing handle and the variable resistor is actuated by rotation of the speed changing handle for varying electrical current to the motor whereby rotational speed of the motor may be varied.
Thus, the electric bicycle as herein described includes a power driving system in combination with a pedal driving system in order to enable the bicycle to be driven either manually or through electrical power, or in combination. The pedal driving system is similar to prior art manually actuated bicycles and inclues a sprocket wheel, a chain, a clutch, and crank arms with pedals. The electrical power driving mechanism includes a motor, a battery, a solar cell and a rectifier for alternating current input. A set of reduction gears is provided in combination with a plurality of bevel gears and a clutch in order to transmit the rotation of the motor through the reduction gears to a transmission gear engaging the sprocket wheel in order that the motor may drive the sprocket wheel to displace the chain and result in displacement of the bicycle.
