12. ABCs of Pedelec
Concept
Pedal assist electric bikes or pedelecs are equipped with an electric motor that provides assistance when the bike is being pedaled. The
assist is activated by a pedal action sensor designed to detect when the pedal is being turned. In Europe, pedelecs are limited to 25 km/h (15
mph). In the United States, the limit is 32 km/h (20 mph). Assistance is cut off above those designated speeds.
The controller allows you to select the degree of power assist provided by the motor from economy to sport mode, enabling you to tailor the
performance of the bike to fit your specific style and road topographies.
Your Tern may use a Mid-Drive Motor or Hub Motor. See the diagram below:

Other Pedelec Features
Walk-assist
Selected Tern pedelecs come with a walk-assist function. It allows the rider to push or trolley the bike with less effort. This is beneficial for
certain road conditions, such as going uphill. The assist is limited to walking speed. Please refer to the motor manufacturer's instruction for
more detail.
Battery lock
Your Tern pedelec may be equipped with a battery lock. Always lock the battery in place before you ride and store the keys in a safe place.
If you lose your keys, contact your local Tern dealer for key recovery service.
