The information is especially important as hybrid vehicles may have the electric motor near the conventional engine or its exhaust, and this may mean they need to tolerate temperatures never before encountered in pure electric vehicles. Motors for highly price-sensitive markets such as electric bikes, scooters, e-rickshaws and micro EVs avoid the price hikes of neodymium and other rare earths in the magnets. In-wheel and near-wheel motors in any vehicle need to be very compact, and sometimes disc-shaped to fit in. However, fairly common requirements can be high energy efficiency and cost-effectiveness, high torque for acceleration, and hill climbing and peak power twice the rated value at high speeds.
