A balance board coupled to a two-wheeled vehicle to provide a moving platform that an operator of the vehicle can use to stabilize the vehicle. The balance board includes a coupling mechanism, a frame, one or more moving elements, and one or more foot support pedals. In one example, the balance board is mechanically passive such that the balance board maintains contact with the ground surface without an externally applied force (e.g., by the operator/user of the vehicle). In one aspect, the balance board may be rotatable about multiple rotational degrees of freedom to allow the balance board to steer as the vehicle turns.

A ski assembly for a bicycle includes a mounting frame with a mounting aperture therein and a wheel axle that is received through the mounting aperture of the mounting frame and extends through one of the wheels of the bicycle to mount the wheel relative to the bicycle while supporting the mounting frame in part relative to the bicycle. Two ski members are pivotally supported on respective support arms that are movable relative to the mounting frame by a biasing member that urges the ski member downwardly. The biasing member can be adjusted relative to the mounting frame between a working position in which the ski members are arranged to engage the ground at opposing sides of the wheel of the bicycle and a stored position in which the ski members are supported in raised elevation and out-of-use relative to the working position.

A bike having an automatic landing wheel apparatus includes a left landing wheel arm on the left side of the bike to vertically move a left landing wheel rotatably coupled to the lower end portion thereof. A right landing wheel arm on the right side of the bike vertically moves a right landing wheel rotatably coupled to the lower end portion thereof. A left driving unit drives the left landing wheel arm to move the left landing wheel upward and downward. A right driving unit drives the right landing wheel arm to move the right landing wheel upward and downward. A speed detection unit detects the speed of the bike. A controller is connected with the speed detection unit, the left driving unit, and the right driving unit to move the left and right landing wheels upward or downward in response to the detected speed of the bike.

An anti-tip device for an all-terrain vehicle (ATV) having a T-shaped first support member formed by a first section and a second section with opposing left and right ends. A trailing end of the first section mounts between the ends of the second section. A leading end of the first section removably connects to the rear end of the ATV. A ground contact member is located on the T-shaped first support member and includes a bottom that is spaced away from the ground surface when front and rear wheels of the ATV are in contact with the ground surface. The ground contact member contacts the ground surface when the front wheel rotates about the rear wheel and away from the ground surface in order to prevent rotation that would cause the front wheel of the ATV to tip backwards over the rear wheel.

A bike having an expanded knife ski device includes left and right landing wheel arms on the left and right portions of the bike, respectively. Left and right landing wheels are rotatably coupled to the lower end of the left and right landing wheel arm, respectively, to move the landing wheels up and down. Left and right driving units lift and lower the left and right landing wheels, respectively. Left and right ski mounting sockets are coupled to the left and right landing wheel arms, respectively. Left and right insertion members couple to the left and right ski mounting sockets, respectively. Left and right ski legs are integrally coupled to the left and right insertion members, respectively, to extend downwards. Left and right bike skis, which are hinge-coupled to the lower end of the left and right ski legs, respectively, each making a hinge movement about a left/right horizontal axis.
