Problems solved by technology

[0002] The definition given by the country of electric power-assisted bicycles is a bicycle that is mainly driven by the human body's physical fitness, and the motor is used as an auxiliary drive. At present, electric power-assisted bicycles on the market control the operation of the power-assisted motor through the pulse switch circuit to sense the riding situation of the rider. , but the current signal of the pulse circuit is a fast electric signal, and the signal processor will instruct the booster motor to accelerate quickly after receiving this fast electric signal, so the power-assisted bicycle using the pulse circuit will produce jerky acceleration during the riding process, which will affect the ride. Continuity and comfort
[0003] In addition, due to structural reasons, no matter whether the center shaft of a traditional power-assisted bicycle rotates clockwise or counterclockwise, the power-assisted motor rotates synchronously with the center shaft. Drive the power-assisted motor to rotate synchronously. At this time, the rotor of the motor cuts the magnetic force lines to generate ampere magnetic field resistance, and it is very difficult for people to ride.
