RPM stands for "Revolutions Per Minute" and it is a measure of how many times the crankshaft in the engine of a bike rotates in one minute. The RPM determines the speed of the bike and also the fuel consumption. The higher the RPM, the higher will be the speed and fuel consumption. Every rotation of the crank results in the movement of the gearbox, which translates to the speed of the engine. RPM plays a crucial role in determining the performance and efficiency of an engine. It is important to choose the right RPM range for your needs in order to have the best possible biking experience. Higher RPM causes the bike to vibrate, which can lead to problems on the rider’s back, legs, and feet. However, a medium RPM range provides a smoother riding experience. Lower RPM in bikes also results in higher fuel efficiency and a more seamless experience.
