Description

Technical Field

[0001] The utility model relates to the technical field of shared bicycles, in particular to a power assist device for shared bicycles. Background Art

[0002] Bike-sharing is a new type of green and environmentally friendly shared economy service based on a time-sharing rental model. It mainly provides services in campuses, subway stations, bus stops, residential areas, commercial areas, and public service areas to help solve the "last mile" problem of public transportation. Bike-sharing companies deploy bicycles in these areas, thereby stimulating residents' enthusiasm for using other public transportation.

[0003] With the development of urban transportation, shared bicycles have played an important role in solving the problem of people's short-distance travel. However, in some complex road conditions, such as climbing a slope or riding against the wind, relying solely on human pedaling will make the rider feel very tired and may even cause him to give up riding. Most existing shared bicycles do not have power-assistance functions, or although there are a small number of power-assistance models, the power-assistance effect is not ideal, which affects the user's riding experience and the promotion and use of shared bicycles. Therefore, those skilled in the art provide a power-assistance device for shared bicycles to solve the problems raised in the above background technology. Utility Model Content
