The disclosed method may include configuring one or more brakes based on a braking-related attribute expected at a geographic location being traversed by a personal mobility vehicle. By configuring the application of brakes of a personal mobility vehicle based on terrain, environmental conditions, and other geographic features, the system may reduce the risk of the vehicle skidding or tipping due to over-braking. In some embodiments, a rider may use a single brake lever to indicate a desire to brake and the system may make determinations about how to apply a combination of mechanical and electrical brakes to front and back wheels based at least in part on the location of the personal mobility vehicle. By configuring brake engagement based on a combination of controls and map data, the system may improve user experience and user safety, especially for inexperienced riders.

An auxiliary wheel mechanism 151 of a two-wheeled vehicle disclosed herein includes an auxiliary wheel 1, a saddle support member 7, a transmission member 9, and an auxiliary wheel urging member 23. The auxiliary wheel 1 is supported by a vehicle body 11 to be located on a side of a rear wheel 13 and to be movable between a retracted position retracted from a road surface 17 and an operative position where the vehicle body 11 is supported against the road surface 17 so as not to tilt. The saddle support member 7 is provided on the vehicle body 11 and supports a saddle 27 such that the saddle 27 is movable backward and forward. The transmission member 9 transmits a backward and forward movement of the saddle 27 to the auxiliary wheel 1 such that the auxiliary wheel 1 is located at the retracted position when the saddle 27 is located at a front position, and the auxiliary wheel 1 is located at the operative position when the saddle 27 is located at a rear position. The auxiliary wheel urging member 23 urges the auxiliary wheel 1 toward the retracted position. Accordingly, it is possible to achieve the auxiliary wheel mechanism that is for the two-wheeled vehicle and enables a rider to move an auxiliary wheel between a retracted position and an operative position without a manual operation of the rider.

Anti-theft device of a bicycle wheel includes at least one braking unit having two pads acting on a rim of the wheel and an actuator to control at least one braking unit. The actuator includes two tie-rods pivoting on shafts and is actuated by a key acting on a key cylinder to press the pads on the rim of the wheel. Each tie-rod is driven at one end by a secondary transmitter piston interacting with a primary transmitter piston and driving a receiver piston holding the pad at its other end. The rotational movement of the key cylinder is converted into a translational movement of the primary transmitter piston by an indirect movement converter.
