Abstract

The invention provides a folding bicycle. The folding bicycle is characterized in that a locking hinged structure is adopted in a cross beam and a vertical beam, a locking hinged structure is adopted in the vertical beam and a rear beam, the connection height of the cross beam and a front fork can be adjusted, the height of a handlebar installed on the front fork can be adjusted, and the position of a saddle at the cross beam can be adjusted; the locking hinged structure is adopted in the cross beam and the vertical beam, the locking hinged structure, an antiskid contact face with teeth and a rapid-installation cam locking structure are adopted in the vertical beam and the rear beam, the front fork is sleeved with the front end of the cross beam, a vertical tube of the handlebar is sleeved with the front fork, and an omega type clamping and rapid-installation cam locking structure is adopted in connection. According to the folding bicycle, the height and the seat position of the bicycle can be fast adjusted, the folding bicycle can adapt to riding of people with different heights and arm lengths, the height and the length of the bicycle are changed through folding, and the overall size is reduced.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a folding bicycle. Background technique [0002] In order to ensure the structural strength, the early bicycle frames mostly used a tripod structure, but it was not very adaptable to people of different heights and arm lengths. Later, there were liftable seats and front handles, which could adapt to people with different leg lengths. Due to the fixed horizontal length of the frame, it is not suitable for people with different arm lengths. Contents of the invention [0003] The invention provides a folding bicycle for solving the riding comfort problem of different heights and arm lengths. [0004] The technical scheme adopted by the present invention is: a folding bicycle, characterized in that the crossbeam and the vertical beam adopt a lockable hinged structure, the vertical beam and the rear beam adopt a lockable hinged structure, the height of the connection between the crossbeam a...
