Description:
The Bike Friday Mid-Drive e-assist system includes a motor and torque sensor in the crankset. That
means the harder you pedal, the more the electric motor will assist. This helps you feel powerful and
capable, and still feels like riding a bike (vs a throttle-based motor vehicle)! A console on the
handlebar lets you fine-tune how much proportional assist is provided plus displays speed and other
ride details.
