Abstract
The utility model discloses a bicycle. The bicycle comprises a front wheel, a back wheel, pedals, a front bicycle beam, and a back bicycle beam, wherein, the front bicycle beam is connected with the front wheel. The back bicycle beam is connected with the back wheel. The front bicycle beam is connected with the back bicycle beam through a chain wheel casing. A driving chain wheel and a small driven chain wheel are connected to the interior of the chain wheel casing. A large driven chain wheel is fixedly connected to a small driven chain wheel. A short chain is connected between the driving chain wheel and the small driven chain wheel. A long chain is connected between the large driven chain wheel and a flywheel of a back wheel shaft. The back wheel is driven through the pedals, the driving chain wheel, the short chain, the small driven chain wheel, the large driven chain wheel, and the long chain and the bicycle can advance. A speed can reach 2.5 times of that of a known manpower bicycle. The utility model has the advantages of rapid speed and convenient physical exercises.
Description
Technical field
The utility model relates to a kind of bicycle and man.
Background technology
Known bicycle comprises front-wheel and trailing wheel, connects the car beam between front-wheel and the trailing wheel, and the car beam connects axis, and axis connects foot-operated and sprocket wheel, is connected with chain between sprocket wheel and the hind axle flywheel.This bicycle advances bicycle by foot-operated by a sprocket wheel and a chain drive trailing wheel, and speed is slower.
