Taking into account the sharp increase in motor transport in the country, the issue of developing bicycle transport is becoming increasingly acute. Therefore, there is a need to improve their operational characteristics. This circumstance contributed to the emergence of a new direction in improving mechanical drives of bicycles that can transmit torque not due to friction, but by engaging balls with the working surfaces of special grooves of the driving and driven half-couplings, which completely eliminates slipping of the contacting surfaces and increases the service life of the working mechanism. Based on the results of the research and development processes of new ball overrunning clutches for multi-speed rear hubs of bicycles, opportunities for clarification of some important provisions have been found, which has allowed the development of more economical mechanical parts of the drives. This describes the analysis of the main operational parameters, the manufacture of a technical design and a clutch in metal, its installation on a serial bicycle, and the operability of the new clutch in real, more critical load conditions is determined. This is the main purpose of this article.
