A gear reduction unit for use particularly in an electric motorcycle. The gear reduction unit uses three adjacent gears. The three gears are straight cut gears, which make a sound when they turn together. The sound provides audio feedback so that bystanders can hear when the motorcycle is approaching, notwithstanding that the electric motor on the motorcycle is mostly silent.
