On the other hand, many of the electric cars are currently made with no gears(some with independant engines inside the wheels). its no good if you stall every time you stop. The gears are used to allow for a wide range of speeds and torques that are required for moving vehicles. this means that if you were to weld the engine to the wheel, you'd need to be going at a speed where the engine could reach 500-800rpm before you could start it.ĭepending on ratios this could be 2-30mph.
