A child's ride-on toy comprising a push rod and a removable cart connected to the child's ride-on toy is described. The push rod of a child's ride-on toy typically extends upward and rearward from a connector at the rear of the frame of the child's ride-on toy to a handle at a height that may be easily manipulated by an adult. The push rod may be manipulated by an adult to control the speed and direction of the child's ride-toy or removed and connected to the cart for use of the cart independently of the ride-on toy.

A Device is fitted to a traditional bicycle to facilitate a riding style in which the rear wheel of the bicycle can slid sideways or drifted in a controlled manner by harnessing the rider's backward pedaling motions to thrust a block of UHMW plastic downward to the road surface.

A removable training assembly for use with a two-wheel standing vehicle having two platforms pivotal with respect to each other. The assembly comprises forward and rearward wheel sets fixed with respect to a connecting structure. The connecting structure is removably attachable to the vehicle such that the platforms of the two-wheel standing vehicle may pivot.

To provide a bicycle trainer with which a wheel is less likely to come off even during low-speed running. A bicycle trainer 100 includes a pair of front wheel rollers 10 and 12 to support a front wheel of a bicycle, a pair of rear wheel rollers 20 and 22 to support a rear wheel of the bicycle, and a belt 66 to transmit a rotation of the rear wheel roller 20 to the front wheel rollers 10 and 12. The front wheel rollers 10 and 12 support the front wheel of the bicycle such that a trail when the front wheel of the bicycle is put on the front wheel rollers 10 and 12 becomes equivalent to a trail when the bicycle actually runs on a road surface. The bicycle trainer 100 further includes front wheel roller adjusters 14 and 16 and rear wheel roller adjusters 24 and 26. The front wheel roller adjusters 14 and 16 adjust postures of the front wheel rollers 10 and 12 such that contact positions where the front wheel of the bicycle contacts the front wheel rollers 10 and 12 become constant. The rear wheel roller adjusters 24 and 26 adjust positions of the rear wheel rollers 20 and 22 according to a driving power or a fictitious force of the bicycle.

A tricycle may be operable between a first mode of operation steerable by a tricycle rider, and a second mode of operation steerable by an individual pushing the tricycle. In both such first and second modes, the frame of the tricycle is configured to rotatably support the rear wheels and configured to support the head tube at a distance from the rear wheels such that a distance between the head tube and rear wheels need not necessarily be changed even when the front wheel axis location is changed from one mode to another.
