<p>Concerning pedal driven front wheel drive cycles we know that the front wheel is not equiped with a crank gear. Also, there is no sprocket freewheel. Consequently, there is no possibility for speeds on those cycles. In the present invention, there is a crank gear made with at least one chainwheel, an intermediate cogwheels mounting and a cycle wheel equiped with a sprocket freewheel. The front wheel axle is rotating by means of cranks with pedals and this movement is transmitted to the wheel freewheel using chains and front fork intermediate cogwheels. The gear changes possibilities of that front wheel permit the manufacture of front wheel drive racing cycles. The front wheel is also steerable by means of a handlebar. The recumbent position adopted by the driver of this pedal driven front wheel drive racing cycle allow better performance than any conventional racing cycle.</p> |
