A treadmill is a device generally for walking or running or climbing while staying in the same place. Treadmills were introduced before the development of powered machines, to harness the power of animals or humans to do work. When we walk or run on the walking surface it gives rotation to rear wheel of bicycle and treadmill bicycle is moving forward. The walking surface of a treadmill consists of the thin moving belt and a rigid plate placed between the two surfaces of that belt in order to provide backing when the transverse load of footfalls is applied. The treadmill driven cycle is constructed by the above mentioned components over the base frame. There are six rollers fitted next to next by certain distance and the belt is connected over the rollers which cover the rollers. The spur gear arrangement is connected to the rear roller for achieving forward motion of the vehicle. Then the chain drive is connected between spur gear shaft and rear wheel. When we walk over the belt, the roller will be rotated and it will rotate the spur gear shaft. Then the power will be transmitted to the wheel shaft through chain drive.  When we start using the treadmill then the rear wheel starts moving and hence the flywheel gets momentum. So once the flywheel gets momentum the bicycle will keep moving due the moment gained by flywheel.      

The main blocks of this project are:                    

• Cycle
• Treadmill
• Bearings
• Chain and sprockets
• Gears
• Shafts
• Rbber belt.
