a2b Kuo+ Owner's Manual page 13

When applying the brake levers the motor will automatically cut
out. This is a safety feature.
Your A2B Kuo+ allows for gradual application of power, and
allows for adjustment of power between OFF and FULL. This
feature enables you to adjust the speed at which you are most
comfortable by the amount of torque or pressure that you apply to
the pedals. See Section 6.4.4
Your A2B Kuo+ will provide instantaneous power when you are
pedalling. To conserve battery power and increase your range,
ALWAYS use the gears as much as possible – just like you would
on a non-powered bicycle.
Remember that there are power cut off switches integrated into
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.
