The electric bicycle flywheel mechanism comprises a ratchet wheel 1, a pawl 2, a pawl seat sleeve 3 and a pawl reset spring 4, the pawl 2 and the pawl reset spring 4 are installed on the pawl seat sleeve 3, an end cover 5 is arranged at one end of the pawl seat sleeve 3, and the pawl 2 comprises a pawl rotating shaft 6 and a pawl body 7. The extension shaft 8 penetrates through the end cover 5 and is in static connection with the handle 9; the outer side of the end cover 5 is further provided with a limiting protrusion 10 arranged on the handle 9. According to the technical scheme, the problems that inconvenience and potential safety hazards are brought to a rider along with rotation of the crank and the pedals when the electric bicycle advances, and the insteps of a passenger on a backseat are possibly injured due to the fact that the pedals rotate reversely along with the rotation of the pedals when the electric bicycle backs are solved.
本发明公开了一种可以调整棘爪角度的电动自行车飞轮机构:包括棘轮1、棘爪2、棘爪座套3和棘爪复位弹簧4,棘爪2和棘爪复位弹簧4安装于棘爪座套3上,棘爪座套3一端有端盖5,所述棘爪2包括棘爪转轴6和爪体7,其特征在于:棘爪转轴6有延长轴8,该延长轴8穿过端盖5并与手柄9静联接;端盖5外侧还有为手柄9设置的限位凸起10。此技术方案解决了电动自行车前进时,曲柄和脚踏板随着转动给骑行者带来不便和安全隐患,而在倒车时脚踏随动反转,可能夹伤后座乘客脚面的问题。
