Overview

An electric bicycle has an integrated electric motor used to assist propulsion.

1. Throttle
   • throttle sends a signal to the motor controller to deliver power to the motor
   • thumb, push, or twist throttle options
   • Class 2 ebikes in the U.S. allow throttle up to 20 mph
2. Pedal assist
   • sensor detects your pedaling activity
     1. cadence sensor - detects if peddling (on/off) [feels jerky]
     2. torque sensor (high end) - detects strength of pedalling
   • motor controller delivers power to motor
