Abstract
The driving controller of a electromotive bicycle is installed on a electromotive bicycle comprising a driving motor and a battery, wherein, the large gear is installed with an arc-shaped slot, compressing spring, and two graphite brushes, and the portions of the inside and outside of the large gear are installed with an inner cover, copper film PC, outside cover, variale resistor, extending spring and other components which are matched with the check plate of the foot pedal crank and convex segment of the crank to drive the frame body to present a rotary movement by two foot pedals, thus the driving controller of the present invention is constructed. In using, when the chain is driven to rotate by the tread force on the foot pedals applied by the rider through the large gear, the current and voltage of the driving motor is provided from the battery controlled by the driving controller so that when the bicycle is in the states of actuating and climbing is driven by larger auxiliary power or the power is switched to the 'off' state automatically when it is sliding down or is driving in high speed.
