Abstract: In this paper we design and implement the motor bike with reverse gear system which is helpful for physically challenged person to take reverse their bike from parking without another person help. Here we used "tumbler gear " mechanism for our prototype model the gear usually used to change the direction of gear it consist of two gear which place in parallel by changing their position with motor direction of rotation can be changed but in real time application we need to use ideal gear system with gear box also the bike consist of ultrasonic sensor which work based on echo signals to give alert on taking reverse to avoid collision between other object it consist of "GPS" which help their family to locate their position easily in case of any emergency and no board is used to control all these electronic modules which is pre-programmed to do this operation of ultrasonic and GPS module and relay driver circuit is used to drive the motor in our prototype.
