6.2 State-of-charge indicator
The state-of-charge (SOC) indicator on the command module
displays the percentage of charge remaining in the battery whilst
you are using your A2B. When the battery is below 20% it should
be charged as soon as possible.
The motor controller and battery management system (BMS) are
designed to turn off the power to the motor when the voltage of the
battery drops to a predetermined point. This is to protect the battery
from the harmful effect of over-discharge.
The display also shows the battery voltage. This allows you to keep
track of the health oft he battery. See Section 6.4.6.
Never attempt to use remaining power once the BMS has
switched off the battery. You will damage your battery. When the
power turns off due to a low battery, plug the battery into the
charger supplied with your A2B Kuo+ to recharge the battery. It will
take 5-6 hours to fully recharge a completely discharged battery.
See Sections 7.2 & 7.3.

6.3 Gears and shifting
Your A2B Kuo+ has a 7-speed Shimano gear set controlled by a
trigger shifter on the right hand side of the handlebar. To shift gears,
pedal at a steady pace and click through the gears until you find
the gear most comfortable for you and the current conditions. To
downshift, to make pedalling easier (when encountering a hill), click
the lower thumb trigger to select a lower gear. This will down-shift
your A2B Kuo+, but will also make you pedal faster to achieve any
given speed.
To ride faster (on a flat section or a downhill), click the upper thumb
trigger to select a higher gear. This action will up-shift your A2B
Kuo+, allowing you to pedal more slowly for a given speed, but with
more effort required.
ALWAYS pedal forward at a steady pace when shifting gears.
The gears operate independently of the motor. To maximise the
range that you can ride with electric assistance, and to give yourself
a pleasant aerobic workout, maximise use of the gears to assist the
motor. The VPAC torque sensor uses a combination of pedal and
motor power to achieve your desired speed. Using the trigger
shifter, adjust the gear setting to find a gear that makes pedalling
comfortable whilst assisting the motor.
Consult your doctor before undertaking any form of physical
exercise and for guidance regarding aerobic workouts.
