The main objective of this paper is used to bring automation in gear shifter of two wheelers using stepper motor. This is the new innovative model mainly used for the vehicles to control the vehicle. Here we are concentrating to design the automatic gear changing mechanism in two wheeler vehicles by using the components like gear box, stepper motor, battery, electronic switch etc. This is very useful and unique method for the gear changing mechanism in two wheeler vehicles. By using this we can easily control the bike through button which will give instruction to stepper motor through programming we going to achieve to control motion i.e. Clockwise or anticlockwise by some specific angle.
