Description

Technical Field

[0001] The utility model relates to the technical field of bicycles, in particular to a bicycle with a speed-changing function. Background Art

[0002] Bicycles with shifting functions are often called multi-speed bicycles. They have multiple gear combinations, allowing the rider to adjust the gear ratio under different road conditions and riding speeds to provide greater efficiency and comfort.

[0003] The paddle shifting system of a bicycle with a speed-changing function changes the gear ratio by using paddles (also called shift handles). When the rider turns the paddles, the speed-changing mechanism moves the chain from one set of gears to another, thereby changing the transmission ratio between the drive wheel and the wheel hub. The paddle shifting system is usually equipped with two paddles, front shifting and rear shifting. The front shifting is used to control the front sprocket, and the rear shifting is used to control the rear sprocket; however, during daily riding, the bicycle chain needs to be lubricated regularly to ensure its smooth operation and extend its service life. At present, when maintaining the bicycle chain, the chain is usually lubricated by manual application, which is inconvenient to operate and difficult to clean when the lubricating oil is stained on the hands.

[0004] Therefore, the utility model provides a bicycle with a speed change function to solve the above problems. Utility Model Content
