the case
necessary, whereby to reduce the energy consumption and to keep the fun of the
traditional
ski. The operation of the motor-snow-scooter with the movable driving system
is very easy.
The volume of the motor-snow-scooter could be minimised to be easily carried.
A motor-snow-scooter of the present invention could be changed to a motor-
water-scooter by
using a special driving wheel unit as a water-wheel unit and an assistant
floating unit,
whereby to permit a motor-snow-scooter to be used on the water.
Thus, one of the objects of the present invention is to provide a movable
driving system
including a motor power unit, a driving wheel unit, a pedal unit, a movable
support unit with
recoverable spring unit, a transmitting unit. The movable driving system can
be moved
