Power-assisted bicycle with middle-mounted motor

Abstract

The invention relates to a power-assisted bicycle with a middle-mounted motor. The power-assisted bicycle comprises a bicycle frame and a middle-mounted motor driving system installed on the bicycle frame. The middle-mounted motor driving system comprises a motor, a controller, a battery and a transmission system; the transmission system is arranged at the lower end of an inclined tube; at least the motor in the motor, the controller and the battery is arranged in the inclined tube of the bicycle frame, and a driving part of the motor is in driving connection with the transmission system; thecontroller is in signal connection with the motor; and the battery is electrically connected with the motor and the controller and supplies a working power supply. Thus, the appearance of the power-assisted bicycle is simplified and tidy, enough space is vacated for folding, the weight is reduced, pedal riding is easy, electric riding power consumption is small, the battery journey continuation time is long, the battery journey is long, and in addition, the middle-mounted motor driving system adopts modular design, so that the power-assisted bicycle is more convenient and faster to disassembleand assemble, and the production efficiency is high; and the production cost is reduced, and later maintenance and replacement are facilitated.

Description

technical field [0001] The invention belongs to the technical field of power-assisted bicycles, in particular to a power-assisted bicycle with a central motor. Background technique [0002] Power-assisted bicycles have the advantages of labor-saving, large load, and fast speed, and have soon become the main tool for people to travel and transport short distances. However, the applicant found that the motor drive systems of existing power-assisted bicycles on the market are all arranged outside the frame, which makes the appearance of the power-assisted bicycle very complicated, cumbersome, and heavy, which increases the difficulty of pedaling. It also increases the power consumption during electric riding, thereby shortening the battery life and distance, and the external motor drive system occupies a certain space, making it more difficult to fold and store the power-assisted bicycle, and the volume increases, which is not conducive to collect.
