Combined electric bicycle

Abstract

The invention discloses a combined electric bicycle as a common vehicle which is portable and stable on performance, simple on structure, suitable for both rural and urban districts and easy for operation. The conception of the electric bicycle takes the integrity into account and the design of the bicycle takes the wheel diameter and human body as standards and the vehicle type can be classified as: type-A direction bicycle; type-B push-bicycle; type-C soft-seat bicycle; type-D relaxing bicycle and type-E luggage bicycle. All the types of bicycle adopt the frame structure and two wheels are fixed inside in a parallel manner; the connecting part on both the front and back parts of the bicycle are unified and provided with the multi-direction turning function so as to lead each wheel to be connected with grounded connectors to form integrated four-wheel or multi-wheel vehicles. All the types of vehicle can be quickly assembled and disassembled and the intermediate-type and mini-type vehicles can be carried into elevators or rooms so as to bring convenience for charging and storage. Moreover, all the types of vehicle can be provided with components of parallel rotary rods and the like and then the parallel wheels can turn synchronously when the pedal or power is adopted, thus being suitable for the travelling by riding bicycle on the common roads and meeting the environment protection requirement. The main parts of the electric bicycle adopt the standard bicycle parts and standard steel pipes and the electric bicycle can be manufactured by the existing bicycle manufacturers.

Description

technical field [0001] The invention relates to the field of bicycles Background technique [0002] The British have invented bicycles for more than 150 years. The rapid development of electric bicycles has proved that the simple, convenient and environmentally friendly design of bicycles is suitable for future development. But, unsatisfactory is: the structure of each round before and after the bicycle is unstable when in use, makes some people can't use, and some people dare not use, and saddle is easy to make people tired when especially medium and long-distance use. Though the design of four-wheel bicycle is arranged in recent years, all because of various reasons, be difficult to popularize. Contents of the invention [0003] The main purpose of the present invention is to provide a light and stable mass transportation tool with simple structure, suitable for urban and rural areas, and easy to handle. Combination electric bicycle of the present invention (hereinafte...
