Abstract

The invention discloses a novel chainless-type dual-speed-variable bicycle which comprises a front speed-variable wheel disc, a rear speed-variable wheel disc and a speed regulating main shaft. The front speed-variable wheel disc sleeves a pedal shaft of a speed-variable bicycle, and the rear speed-variable wheel disc sleeves a rear wheel shaft of the speed-variable bicycle. The speed regulating main shaft is arranged between the front speed-variable wheel disc and the rear speed-variable wheel disc, one end of the speed regulating main shaft is in meshing connection with the front speed-variable wheel disc, and the other end of the speed regulating main shaft is in meshing connection with the rear speed-variable wheel disc. The front speed-variable wheel disc and the rear speed-variable wheel disc are used for realizing the multi-gear dual-speed-variable adjustment of a pedal position and a rear wheel position of the speed-variable bicycle under the action of the speed regulating mainshaft. The novel chainless-type dual-speed-variable bicycle has the advantages of the simple structure, long service life, high transmission efficiency, the high power conversion rate and labor-saving riding, and the multi-gear dual-speed-variable adjustment of the pedal position and the rear wheel position can be simultaneously realized.

Description

technical field [0001] The invention relates to the field of bicycles, in particular to a novel chainless double-speed bicycle. Background technique [0002] With the popularity of the concept of low-carbon and environmentally friendly life, today's bicycle is not only a means of transportation, but also a healthy and fashionable way of life. Most of the current bicycles use the chain transmission method to provide forward power for the bicycle, and there is no variable speed adjustment function. Some bicycles with variable speed adjustment function have also appeared on the market, but most of them have complicated structures and expensive prices, which are not acceptable to the general public. Contents of the invention [0003] The purpose of the present invention is to provide a novel chainless double-speed bicycle, which is used to solve the problems in the background technology. [0004] In order to achieve the above-mentioned purpose, the technical solution adopted...
