A training wheel assembly for assisting a physically disabled user with riding a bicycle includes a pair of brackets that is each mountable on opposite sides of a rear wheel of a bicycle. A pair of shock absorbers is each integrated into a respective one of the brackets such that each of the brackets is compressible and expandable. A pair of rollers is each of rotatably coupled to a respective one of the brackets to roll along a support surface when the bicycle is ridden. Each of the rollers is positioned on opposite sides of the bicycle to inhibit the bicycle from tipping thereby assisting a physically disabled user with riding the bicycle.

A foldable baby stroller movable between unfolded and folded states. The stroller includes a frame, a front wheel assembly on a front portion of the frame including a front wheel, a rear wheel assembly on a rear portion of the frame including two rear wheels, and a seat assembly on an upper portion of the frame. The frame includes a head tube; at least one beam having a first end pivotally connected to the head tube; at least one joint, to which a second end of the beam is pivotally connected; and at least two rear fork rods having a first end pivotally connected to the joint and a second end connected to the rear wheel assembly. Parts of the foldable baby stroller do not need to be detached during folding, thereby implementing “one-click” folding, and making the operation more convenient and efficient.

A teaching aid for rotary motion of a pedal-driven wheeled vehicle features an arm configured to span from a lower end thereof positioned at a rotary pedal assembly of the pedal-driven wheeled vehicle in an upwardly and longitudinally inclined orientation to an upper end of the arm positioned at a longitudinally spaced location from the seat of the pedal-driven wheeled vehicle, which upper end is configured for gripping by a user. The aid further features a connector supported on the arm at or adjacent the lower end thereof, which is configured for attaching to the rotary pedal assembly on one side of the vehicle and at a spaced location from an axis of rotation of the rotary pedal assembly such that the arm acts as an extension for the user to drive rotary motion of the rotary pedal assembly by the user's hand.
