Hello friend Is not gearing helpful for efficient power transfer? I have owned a few electric bikes, and most people agree that mid-drive motors are much better at turning watts into speed. Why does not this apply to electric cars or motorcycles?
Electric cars do not use hub motors, so they could easily have a transmission. Some say fewer moving parts mean less maintenance, but I think this might wear out the motor more and reduce power efficiency, especially since the range is such a big concern right now.
Because an electric motor serves as the vehicle’s “engine,” multi-speed gearboxes are not necessary for electric vehicles. Internal combustion engines need several gears with distinct ratios in order to produce power, but electric motors can generate a constant torque output at any given RPM within a certain range.
E-bikes and electric cars, on the other hand, work in different ways. Most e-bikes can only go a certain speed, but electric cars need to be able to go faster on the highway. Electric cars with transmissions are more complicated and may lose energy, which isn’t good for getting the most range.
