The invention discloses an electric power-assisted bicycle which comprises a frame, a wheel assembly and a power assembly, the wheel assembly comprises a front wheel and a rear wheel, each of the front wheel and the rear wheel comprises an inner rim, an outer rim, a magnetic suspension mechanism and a rubber tire, the power assembly comprises a power supply, a driver and a transmission mechanism, and the transmission mechanism adopts a gear transmission mode. According to the electric power-assisted bicycle, the structural form of the inner rim and the outer rim is adopted for the wheel assembly, spokes are omitted, and the safety coefficient of the electric power-assisted bicycle is increased; the magnetic suspension mechanism is arranged between the inner wheel rim and the outer wheel rim, so that the outer wheel rim is in a suspension state, the purpose of vibration reduction is achieved, and the riding stability of the electric power-assisted bicycle is improved; the transmission mechanism adopts a gear transmission mode, so that the transmission efficiency is improved, the problem that a transmission chain is easy to fall off in a chain transmission mode in the prior art is solved, the working reliability of the transmission mechanism is improved, and the riding stability of the electric power-assisted bicycle is further improved.

    本发明公开一种电动助力自行车,包括车架、轮部组件以及动力组件,轮部组件包括前轮和后轮,前轮和后轮均包括内轮圈、外轮圈、磁悬浮机构以及胶胎,动力组件包括电源、驱动器和传动机构,传动机构采用齿轮传动方式。本发明的电动助力自行车,轮部组件采用内轮圈和外轮圈的结构形式,取消了辐条,提高了电动助力自行车的安全系数;本发明在内轮圈与外轮圈之间设置磁悬浮机构,使外轮圈处于悬浮状态,达到减振的目的,提高电动助力自行车的骑行稳定性;传动机构采用齿轮传动方式,提高了传动效率,避免了现有技术中链条传动方式传动链条易脱落的问题,提高了传动机构的工作可靠性,进一步提高了电动助力自行车的骑行稳定性。
