Engagement Lever Operation
Rider Power Only
The engagement cam is in the “up” position, and the
motors are off and hang free, just clearing the tire. This
mode is for riding when power is not needed and allows
the rider to pedal without any drag from the motor. Fig.1
Motor-Assisted
After pedaling has initiated, activation of the throttle
switch on the handlebar causes the motor to swing into
contact with the tire and engage. The motor then auto-
matically adjusts itself to maximum efficiency at lower
torque levels. Fig.2
Full-Time Power-Assisted
After pedaling has initiated and when the engagement
cam is moved to the “down” position, the drive roller is
already in contact with the tire when the motor is activat-
ed. Pedaling over 11 mph in the low speed setting
recharges the battery. This recharging is called “regen-
eration”. Fig.3 (To learn more about regeneration, refer
to page 9).
