Abstract

The invention discloses a bicycle drive system. The bicycle drive system comprises a drive belt, a rear flywheel and a crankset, wherein the drive belt is installed on the periphery of the rear flywheel and the crankset, belt holes are formed in the drive belt, the rear flywheel is installed on a wheel shaft of a bicycle rear wheel, and teeth are arranged on the crankset and matched with the belt holes in the drive belt. According to the bicycle drive system, since the drive belt is provided with a few components, the weight of the drive system is greatly reduced, and the bicycle drive system is simple in structural design and easy to install and replace. The bicycle drive system is preferably suitable for small-diameter single-speed bicycles with ultra-light requirements.

Description

technical field [0001] The invention relates to a bicycle transmission system, in particular to a portable bicycle transmission system. Background technique [0002] Bicycle is a kind of environment-friendly means of transportation, and it is also a fitness tool with health care function. With the development of the times, people are more and more fond of bicycles that are light and easy to operate. In order to obtain a light bicycle, its various components should be as light as possible under the premise of meeting the requirements for use. [0003] The transmission system is an important part of a bicycle. The transmission system of an ordinary bicycle is a chain transmission system, and stainless steel chains are mostly used. This chain is not only complicated in composition but also heavy in weight, which does not meet people's requirements for the lightweight performance of bicycles. Contents of the invention [0004] In order to solve the above problems and defects,...
