A balance training device includes an inverted two-wheel vehicle, a posture detection unit that detects a posture of the inverted two-wheel vehicle, a control unit that enables control of the inverted two-wheel vehicle so that the inverted two-wheel vehicle moves according to the posture of the inverted two-wheel vehicle detected by the posture detection unit and control of the inverted two-wheel vehicle so that the inverted two-wheel vehicle is forcibly moved in an arbitrary direction irrespective of the posture of the inverted two-wheel vehicle, and a position determining unit that determines a position of the inverted two-wheel vehicle. When a distance between the obtained position of the inverted two-wheel vehicle and the reference position is greater than or equal to a threshold, the control unit suppresses the control to forcibly move the inverted two-wheel vehicle in a direction from a reference position to the position of the inverted two-wheel vehicle.

A chain separator for separating a chain of a bicycle from a sprocket of the bicycle. The chain separator includes a body defining an outer surface and at least one projection extending from the body to define a sprocket channel. The chain is disengaged from the sprocket and positioned on the outer surface and the chain separator is positioned on the bicycle such that the sprocket is positioned within the sprocket channel.

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.

The present disclosure provides systems, methods, and devices for providing stability to a vehicle using one or more auxiliary support members on the vehicle, such as lateral sides of the vehicle. The auxiliary support members may extend away from the vehicle body to approach and/or touch a support surface and provide stability and in some cases additional centripetal force to facilitate steering of the vehicle. The auxiliary support members may also retract towards the vehicle.

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.

The present invention relates to a training wheel assembly for bicycles that enables riders to develop balance while improving performance. This assembly features an adjustable tension system with discrete settings to gradually reduce support as the rider's skills improve, ensuring balanced forces on both sides for stability. A rotational stop feature prevents excessive tilting, while simplified components such as a top bracket, bottom bracket, pivot pin, and tensioning element streamline construction. The tension mechanism utilizes elastic materials and discrete adjustment points, offering a controlled, customizable riding experience for beginners.
