Abstract
This utility model relates to the field of road bike technology and discloses a semi-pneumatic road bike for racing. The connecting shaft has locking nuts threaded to both ends. A sleeve is rotatably mounted on the outer side of the connecting shaft via a bearing. A flywheel disc is fixedly mounted on one end of the sleeve, and a brake pad is fixedly mounted on the other end. A connecting rod is movably mounted on the top of the rear fork via a hinge. A fixed housing is fixedly mounted on the other end of the connecting rod. An extension rod is fixedly mounted on the side of the fixed housing. A pneumatic motor is detachably mounted inside the fixed housing. A drive gear is fixedly mounted on the output end of the pneumatic motor, and an auxiliary gear meshes below the drive gear. This application achieves semi-pneumatic control of the cylinder and pneumatic motor through manual operation of multiple control valve assemblies, combining manual operation control with pneumatic assistance to ensure time and effort savings during riding.
