GRACE EASY Manual

Your GRACE EASY

The GRACE EASY is a member of the class of electric power-assisted motorcycles, also known

as EPAC's. The motor only provides assistance when you apply force to the pedals.

The force applied by the rider is measured in terms of speed, pedalling frequency, and

torque through which the motorised assistance is adjusted. The maximum assisted speed is

25 km/h (15.5 mph) or 32 km/h (20 mph) in the USA as a Pedelec, or 41 km/h (25.5 mph) as

an S-Pedelec. The electric motor switches off once this speed is reached. However, you are

also free to travel faster than the maximum assisted speed with your own pedal power and

without support from the electric motor.
