Each battery comes with two keys that are unique for each battery. The paired lock and key is compatible with all FM 750 and FM 500 electric bikes.
The battery can be charged both on and off the bike. The indicator lights on the side of the battery allow you to check the charge when the battery is not connect to the bike.
The internal latch and grooves make a secure connection with the bike so the battery does not move when in operation.
