Abstract

The present invention relates to bicycles and is used to produce bicycles with a wide range of handlebar height variations. This solution allows for a wide range of handlebar height adjustment, allows for an easier and faster method of changing handlebar height without the use of locking clamps, allows for the brake lines and cables to be completely housed within the frame cavity and All the way down to the handlebar grip, shock absorbers can be installed and shock absorption simplified as well as handlebar control easier. The bicycle includes: a frame, wheels, a seat, a handlebar, a steering wheel fork, and a reduction gear connected between the center of the steering wheel and the center of the fork to transmit the rotational torque of the handlebar to the steering wheel fork, wherein the handlebar The torque is transmitted to the steering wheel fork via a gear system, in which the axes of the steering wheel fork's shaft and gear are set non-parallel to the steering wheel's axis of rotation, and the actual shaft of the steering wheel fork is placed in the cavity of the frame In one part, the part is formed at an angle relative to the axis of the steering shaft.

Description

technical field [0001] The invention relates to bicycles, and the invention can be used to produce bicycles with a wide range of handlebar height variations. Background technique [0002] A known folding bicycle (RU108405U, published on September 20, 2011) includes a frame, a handlebar coupled to a handlebar extension, a front fork for a front wheel and a rear fork for a rear wheel, a seat, pedals, a The pedals are coupled to the chain drive portion of the rear wheel, and the bottom bracket assembly, where the frame consists of a fixed portion and a movable portion consisting of a crossbar and a swivel bushing coupled to the handlebars at one end via a head hanger and the tie tube, down tube, and center tube of the front fork, and a crossbar support coupled to the rear fork via a support tube and a rear fork tube at the seat tube (a fixed portion where the seat tube is coupled to the frame). Another known bicycle (RU2391244, published on June 10, 2010) comprises a frame wit...
