Abstract

The invention relates to a vehicle, in particular to a spokeless and chainless gear-driven bicycle, comprising a vehicle frame, a front wheel, a rear wheel, a handlebar, a handlebar shaft, a brake assembly and a seat, and the handlebar is fixed on the bicycle The top of the rotating shaft and the rotating shaft of the handlebar are movably fixed on the front part of the vehicle frame, and the vehicle seat is fixed on the upper rear part of the vehicle frame. The front wheel and the rear wheel are respectively a spokeless front wheel and a spokeless rear wheel. The wheel is fixedly installed at the lower end of the handlebar shaft. The lower part of the frame is fixedly equipped with a gear transmission gearbox. The two sides of the gear transmission gearbox are respectively connected with pedal assemblies. The rear part of the gear transmission gearbox is matched with a spokeless rear wheel. The spokeless and chainless gear-driven bicycle of the present invention has a novel design, constant instantaneous transmission ratio of power transmission, high reliability of the gear, and the spokeless design can not only ensure strength, but also conform to aerodynamics, and the antler-shaped handlebar is more practical , more user-friendly.

Description

technical field [0001] The invention relates to a vehicle, in particular to a spoke-less and chain-gear-driven bicycle. Background technique [0002] Bicycles have always been a relatively common means of transportation in our country, and our country is also known as the country with the most bicycles because of the large number of bicycles. There are a variety of bicycle brands on the market, but the current bicycle structure is very single, and they all use chain drive and belt drive. There are many problems in the use of chain transmission, such as the instantaneous transmission ratio is not constant, and the chain often breaks, the transmission reliability is not very high; the wheel adopts spoke rim, the aerodynamics The performance is average and the reliability is not good enough. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of single design structure, inconstant instantaneous transmission ratio and poor aerody...
