Battery/Bicycle types

Bicycles are classified into groups based on their battery types. RMB bicycles use RMB batteries, etc.

RMB

"Rack-Mounted Battery". Batteries slide vertically into rear rack. See RMB Bicycles

RTMB

Power systems

PAS

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.

PAS/TAG

Pedal Assist/Twist-and-Go; Allows rider to switch between PAS and TAG, usually with a handlebar-mounted switch

TAG

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.

TMM

Torque Measurement Method; A strain gauge mounted in the rear drive-side dropout measures force applied to the pedals and activates the motor accordingly.
