An embodiment of the invention provides a method and system including a sensor on a vehicle and a processor connected to the sensor. The processor determines a probability of falling based on input from the sensor, whether the probability of falling exceeds a threshold, and a state of an operator of the vehicle. An actuator connected to the processor receives a signal from the processor when the probability of falling exceeds the threshold and when the state of the operator includes an impaired state. Stabilizer wheels are connected to the actuator, where the signal includes a command to deploy the stabilizer wheels.

A pedal thickness supplementary device is provided. The pedal thickness supplementary device includes two supplementary assemblies and a plurality of fasteners. The two supplementary assemblies disposed on two corresponding sides of the pedal respectively, in which the two supplementary assemblies clamp and couple to the pedal, so that the thickness of the two supplementary assemblies clamping to the pedal is thicker than the thickness of the pedal. Further, each of the two supplementary assemblies includes two anti-slip portions, a plurality of first fasten grooves, a plurality of second fasten grooves and a through hole.

A training bicycle with a removably attachable pedal unit enabling adjustment of chain slack by a simple method is provided. The detachable pedal unit is configured to enable attachable/detachable connection of a pedal crank to a bicycle body. The pedal unit includes a unit body having a unit connector for rotatably retaining and fastening to a bicycle body a pedal crank axially supporting a chain wheel. A unit receiving member fixedly installed on the bicycle body to interconnect with the unit connector. A sliding adjustment mechanism provided on the unit receiving member and the unit connector to vary and fix mutual fore-aft connection position of the unit receiving member and the unit connector in order to adjust fore-aft connection position of the bicycle detachable pedal unit relative to the bicycle body and thereby adjusting the chain tension.

A training wheel assembly for a bicycle comprising a generally vertical support arm mounted to a bicycle frame, a generally horizontal support arm, pivotally mounted to the vertical support arm by a hinge joint, and a resistance gas cylinder attached to the vertical support arm and horizontal support aim to provide resistance to the pivot action of the arms.

A stabilization system for maintaining a two-wheeled vehicle, such as a bicycle, in an upright position is disclosed. The stabilization system includes a wheeled frame that can be coupled to the main body of the two-wheeled vehicle. The wheeled frame includes a horizontal balancing arm that extends outwardly from the bicycle body, and shock absorbers that act to maintain the bicycle in an upright position when the bicycle is not in motion.
