Different types of electric motorcycles include those with direct current, single-phase alternating current, three-phase induction and permanent magnet motors. Single-phase and three-phase motors use alternating current, which is more efficient than direct current and requires less maintenance.
Modern electric motorcycles use high-voltage, lithium-based batteries. Direct current electric motorcycles can have either brushed or brushless motors. Permanent magnet motors are less common because they tend to be less efficient. The top-rated electric motorcycles for 2015 include the Zero SR and Zero FX, according to Motorcycles.com. The Zero SR is an electric sport motorcycle, and the Zero FX is an electric dirt bike.
