Two Wheel Drive Motorcycle

Nowadays people concentrate more and more on the comfort and operability of automobiles. Four
wheel-drives in cars have become popular and are in demand in the automotive sector. But the advancement in
two wheelers was limited. The concept of two wheel drive motorcycles was not successfully and economically
implemented. Two wheel drive motorcycle is desirable in situations where there is rough terrain and high
inclination roads which are tiresome and difficult to drive with the conventional rear wheel driven motorcycles.
The two wheel drive bikes are apt for farmers, military applications, desert drive etc. The proposed design
provide economical and user friendly two wheel drive. The use of chain drive and sprockets help in reduction of
power loss during transmission of power from the engine to front and rear wheels. The lightweight ‘all-
mechanical system’ is used to obtain two wheel-drive. Under optimum traction conditions, the rear wheel is
actually driving faster than the front wheel and the one-way clutch within the system allow the front wheel to
freewheel under these conditions. At this point, the two wheel drive system is effectively passive. Though the
front drive system is turning, it is not actually transferring power to the front wheel. When the rear wheel loses
traction, the drive ratio, relative to your forward speed, changes. The two wheel drive system engages
transferring power to the front wheel until traction is re-established at the rear wheel.
