Turning the bicycle ON and OFF
The electric bicycle can be ridden like a normal bicycle with the power turned ON or OFF. However, the
Pedal Assist and Throttle will be active only if the power is turned ON.
Locate the power button on the left side of your handlebar.
• Press and hold the power button for a couple of seconds
• The LCD display panel will will turn on, giving an indication of the battery’s charge level and selected
assist level.
• D-Class can now ride on battery power alone. Throttle and Pedal Assist will be available at the same
time.
• Pressing and holding the power button again will turn off the controller.
• Power should be turned off after each ride to avoid draining the battery. If not, it automatically turns
off within 5 minutes.
Using the Brakes
The bike comes equipped with front and rear Tektro hydraulic disc brakes; the very best available for e-
bikes. The brake's main function is to slow down or to stop the bicycle.
• The brake on the front wheel is controlled by the lever on the left-hand side of the handlebar.
• The brake on the rear wheel is controlled by the lever on the right- hand side of the handlebar.
• When slowing down on slippery surfaces, use the rear brake first before applying the front brake.
• A signal wire from each brake lever automatically cuts power to the motor when either brake is being
used. This prevents undue wear to the electric motor.
Your new brakes go through a “Bedding In” period. Which means that after the first 40 to 50 Full stops,
they will wear down to achieve the 100% grip efficiency, resulting in an adjustment needed
