6.4.11.Power assistance options
The A2B Kuo+ has two types of
assistance for you to choose from,
Power on Demand via the Throttle,
or Pedal Assist. They can either be
used simultaneously or individually.
Left side of your display at your
handlebar you will find the Thumb
Throttle.
Power on demand via the throttle
Apply motor power by pressing the thumb throttle.
The electrical system of your A2B allows for gradual application
of power, and allows for adjustment of power between OFF and
FULL. This feature enables you to set that speed at which you are
most comfortable.
The electrical system of your A2B will provide instantaneous power
whether you are pedalling or not. Therefore, there is no need to
pedal as you start-up.
However, the motor consumes more power during a start from a
standing stop than at any other time. More power is consumed
during start-up than even climbing a steep hill. Therefore, in order
to conserve battery power, and increase your overall range, pedal
during a start from a standing stop to reduce the load taken
from the battery.
Remember that there are power cut-off switches imbedded in the
brake levers. When you apply the brakes, power to the motor will
turn "OFF". Therefore, do not hold the brake lever(s) when you want
the motor to run.
Pedal assist
Choose a level of assistance on the display and begin pedalling.
The electrical system of your A2B allows for application of power
according to the pedal assist settings chosen. The are five support
levels (see also changing support modes) . This feature enables
you to set the speed at which you are most comfortable.
The electrical system of your A2B will provide instantaneous
power when you begin pedalling. However, the motor consumes
more power the higher the chosen assistance level is.
