Patent ID: 8876657

Claim:
An automatic gear bike having a speed control system, comprising: a control assembly including a controller in communication with at least one sensor, wherein the at least one sensor detects the bike speed and sends a signal to the controller, a motor assembly in communication with the controller and adapted to receive control signals from the controller, the motor assembly includes a motor, a motor controller and a beam gear operatively connected to receive power from the motor; a gear assembly includes a ration gear, a planetary gear system, a hub, and hub embedded gear, the ration gear is operatively connected to the beam gear, and the hub embedded gear is connected to the hub; wherein the planetary gear system includes a plurality of planetary gears adapted to rotate about the interior of the ration gear, and a flywheel adapted to engage a bike chain, the flywheel including a plurality of axes operatively connected to the respective plurality of planetary gears such that power is transferred between the planetary gears and the flywheel; wherein the controller receives a signal from the at least one sensor to detect the bike speed, and compares the detected bike speed to a pre-selected bike speed and, based on the comparison, sends a signal to the motor to selectively transfer power to the beam gear and operatively connected gear assembly, in order to increase or decrease the bike speed such that the bike speed is substantially equal to the pre-selected speed.
