not powered), so they cannot generate power. Center drive motors cannot generate power for the same
reason: the spinning wheel is mechanically disengaged from the electrical system except while the motor is
running.
PEDAL-ASSIST SENSORS
Most electric bikes use pedal assist sen¬sors to naturally combine the motor’s effort with the rider’s. The
most common sensors electronically measure pedal crank rota-tion (cadence), pedal pressure (torque), or
wheel speed. Many bikes make use of all three types together.
Throttles
Most electric bikes sold in the United States are equipped with a throttle. Like on a motorcycle, throttles
are designed to let the user apply 0-100% of the motor’s power at will. Depending on the bike, the throttle
either acts independently, or in tan¬dem with a pedal assist sensor.
BRAKES
The brakes on an electric bike are the same as on a normal bike, with one excep¬tion: most have integrated
cutoff switches which kill the motor when activated. These “inhibitor” switches are a safety feature
designed to prevent the motor from acci¬dentally engaging and causing injury. If for any reason you need
the motor to stop turning, remember to simply squeeze one of the brake levers.
A CAUTION
Not all electric bikes have brake inhibitor switches. Be sure to read the instruc-tions provided with your
bike to learn more about its specifc features.
