A motorcycle safety and training device that selectively restricts the maximal effective height of a motorcycle's front wheel above the ground. The device generally comprises a lightweight, adjustable bracket assembly that may be affixed to a rear suspension swingarm of a motorcycle, and one or more preferably pneumatic wheels located at or near the free end of the assembly. When the device is affixed to a swingarm, the assembly extends generally rearward beyond the rear wheel of the motorcycle in one of a variety of selected positions, and during use the device moves in conjunction with the swingarm relative to the suspended chassis of the motorcycle.

A seat device for a kickboard, with a seat unit and with at least one first fastening unit for fastening to the kickboard. The seat device comprises at least one storage unit with at least one receiving region that is provided for receiving objects and is at least approximately completely enclosed in at least one state.

A wheeled vehicle with a ball hoop apparatus has a main body, multiple wheels, a pushing pole, and a hoop. The main body has an assembling mount. The multiple wheels are rotatably assembled to the main body. The pushing pole is detachably assembled to the main body. The pushing pole is able to be assembled to the assembling mount and has a top end. The hoop is assembled to the main body and is able to be assembled to the top end of the pushing pole. The pushing pole may be erectly assembled to the assembling mount. The hoop may be assembled to the top end of the pushing pole. The wheeled vehicle with a ball hoop apparatus provides a shooting ball function.

A seat bump stop has a pad having a first end and a second end separated by a width of 3-8 inches, the pad having a height that is between 1-5 inches. The seat bump stop further includes a mounting system for adjustably and removably mounting the pad on the motorcycle seat. The mounting system including a first strap attached to the first end of the pad, a second strap attached to the second end, and a fastener for fastening the first and second straps around the motorcycle seat.

A balance bike conversion system may include first and second protective inserts, each having an interface adapted to engage opposite ends of a bicycle bottom bracket. A connector may be adapted to connect the first and second protective inserts, thereby securing the inserts to the bottom bracket. The connector may be adapted to adjust the distance between the inserts, thereby accommodating variability in the width of the bottom bracket. The system may further include adapters to enable the system to be used with bicycles having bottom brackets with different diameters. The protective inserts and/or adapters may provide mechanical support to the bottom bracket, thereby protecting it from damage.
