4.0 Understanding your A2B
After having read this section, if you are still unsure, please ask an Ultra Motor dealer to explain any functions or features
that you do not understand before your first ride.
4.1 A2B Overview
The A2B has a ’true pedal assist’ function, this means
the motor engages only when the rider is pedalling. So
you can get places under your own steam yet have
the comfort of the electric motor giving you that extra
boost along the way.
The A2B is equipped with a Torque Sensor, which means
as soon as you start to pedal, you’ll feel the motor kick
in to complement your pedalling – making riding an
effortless pleasure.
4.2 Starting and stopping
1. Put your helmet on and select a quiet area away from
cars, other cyclists, obstacles or other hazards.
2. Make sure that the battery is fully recharged.
3. Power ON the electronic system by turning the battery
power on.
4. Select your prefered assist level mode (see 4.3).
5. Raise the kickstand into the riding position.
DO NOT sit on the A2B while it is supported by the
kickstand, you will damage the kickstand and, possibly
the frame.
6. Mount your A2B and get comfortable.
7. Apply motor power by pedalling the A2B.
8. Test the brakes at slow speed. The right brake lever
actuates the rear brake and the left brake lever
actuates the front brake. Applying brakes too hard can
lock up a wheel, which could cause you to lose control
and fall.
Remember that there are power cut-off switch es
embedded into the brake levers. When you apply the
brakes, power to the motor will turn OFF. Therefore, do
not hold the brake levers when you want the motor to
run.
9. Check out the handling and response of your A2B.
Familiarise yourself with how the suspension responds to
application of the brakes and shifts in rider weight.
