Throttles
Throttle, are equipped on some models of electric bicycles. Throttles operate
be rotating the throttle much like a motorcycle. They generally are the inner
half of the right side handlebar grip and may also contain a battery gauge.
The more you twist the throttle, the faster the motor system will propel
bicycle.
TAG Throttle
TAG (Twist and Go)
Before you begin riding, turn the main power switch on, then start riding as
you would ride a regular, non-motor assisted bicycle. After you have begun to
ride, slowly twist the throttle (on equipped models) towards you .The more
you twist the throttle, the more motor power will be applied to the wheels.
You may feel the pedals get a “lighter” feel than riding without the motor
assisting you. Once you have twisted the throttle all the way, the motor will
accelerate you to its full speed of about 15mph (24km/h).
PAS (Pedal Activated System)
Electric bicycles with this system have a throttle that is only active when the
pedals are in forward motion. A sensor ring on the bottom bracket spindle
rotates and a sensor reads this rotation.
Begin by first riding as if you are on a normal non-electric bicycle, then while
the pedal are in motion slowly twist the throttle towards you the activate the
motor power.
