Abstract
The present invention discloses a coaster cycle having a front half which works similarly to a bicycle wherein it has handle bars that turn the front wheels. The front wheel turns left and right and also leans in both a left and right direction. The front wheel leans left to right and is connected to the rear wheels by a frame having multiple pivotal couplings so that the rear wheels lean left or right with exactly the same angle as the front wheels. The leaning of the front and rear wheels in concert gives the frame a unique design which allows it to make left and right high G-force turns in a very stable manner. Additional embodiments are disclosed which comprise twin, internal combustion engines being placed on the rear wheels of the vehicle in order to power the vehicle which also have independent thumb control throttles for controlling the rear wheels individually. An additional embodiment comprises having snow skis attached to the underside of the vehicle to allow it to be used on snow and also having ice-skate like members attached to the underside of the vehicle to allow it to be used on ice.
