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.

    本发明涉及一种中置电机的助力自行车,包括有车架和安装在车架上的中置电机驱动系统;所述中置电机驱动系统包括电机、控制器、电池和传动系统,所述传动系统设置在斜管的下端上,所述电机、控制器和电池中至少电机设置在车架的斜管内,且电机的驱动部与传动系统驱动连接,所述控制器与电机信号连接,所述电池与电机和控制器电连接,供给工作电源。这样,即可使助力自行车的外观简化、整洁,为实现折叠腾出了足够的空间,且重量减轻,脚踏骑行轻松,电动骑行耗电量少,电池续航时间和路程长,另外中置电机驱动系统采用了模块化设计,使助力自行车拆装更方便、更快捷,生产效率高,生产成本降低,且有利于日后维修、更换。
