Problems solved by technology
[0003] In order to allow the electric bicycle to cope with different road conditions, the electric bicycle will also be equipped with a transmission to provide different gear changes, but when the transmission performs the action of the shift line, the electric motor has no way to adjust the auxiliary power output at the same time. When the auxiliary power output by the motor is too high or too low, it will affect the driving speed of the electric bicycle or the rotation speed of the chainring, which will cause the transmission to fail to operate smoothly

The invention relates to a variable speed control device for an electric bicycle. The variable speed control device comprises a variable speed sensor, a motor and a power-assisted controller, wherein the power-assisted controller is electrically connected with the variable speed sensor and the motor, and can be used for receiving a variable speed signal output by the variable speed sensor during detection of variable speed actions, and controlling the motor to stop, reduce or increase the provided assistant power in a certain time according to the received variable speed signal under different conditions so as to smoothly finish the variable speed actions.
Description
technical field [0001] The invention relates to bicycles, in particular to a speed change control device for electric bicycles. Background technique [0002] Traditional electric bicycles obtain forward power through the pedaling force of the rider combined with the auxiliary power provided by the motor, so that the electric bicycle will not cause too much load on the physical strength of the rider, and allows the rider to enjoy leisure time. The rest can also achieve the purpose of fitness. [0003] In order to allow the electric bicycle to cope with different road conditions, the electric bicycle will also be equipped with a transmission to provide different gear changes. However, when the transmission performs the action of the shift line, the electric motor has no way to adjust the auxiliary power output at the same time. When the auxiliary power output by the electric motor is too high or too low, it will affect the driving speed of the electric bicycle or the rotation...
