Bicycles are classified into groups based on their battery types. RMB bicycles use RMB batteries, etc.
- "Rack-Mounted Battery". Batteries slide vertically into rear rack. See RMB Bicycles
- "Rack-Top Mounted Battery". Battery slides horizontally into rear rack. See RTMB Bicycles
- Battery is hidden inside bicycle downtube. Some are easily removable and designed to be quick-swapped (Bike:Via_Urbano), some require disassembly to remove the battery (TMM Bicycles).
- Digital Multi Meter; Device that allows testing of, among other things, voltage and continuity
- Connector used for charging on most Currie bikes and scooters. The '3' refers to the three pins in the plug
- Starting in 2010, XLR-3 is only used for 24V batteries
- Connector used for charging on 36V Currie bikes and scooters. The '4' refers to the four pins in the plug
- XLR-4 is only used for 36V batteries
- Pedal Assist; In this mode, the twist-throttle is only active when the pedals are in forward motion. A sensor ring on the bottom bracket spindle rotates when the pedals are turned. A sensor picks up this rotation and activates the throttle when necessary. After a few seconds of pedaling in this mode, the motor will automatically spin up to 50% power to provide additional assistance.
- Pedal Assist/Twist-and-Go; Allows rider to switch between PAS and TAG, usually with a handlebar-mounted switch
- Twist-and-Go; In TAG mode, the twist-throttle is always active. The pedal sensor is disabled in this mode, and the motor will not activate unless the throttle is turned.
- Torque Measurement Method; A strain gauge mounted in the rear drive-side dropout measures force applied to the pedals and activates the motor accordingly.
