In case you have fully unscrewed "A" and the lever travel is still excessive,
you will have to adjust the space between the pads and the disc.

PEDALLING POWER
The bike is equipped with a set of electric/pedalling power system. The motor will help you a lot.
The electric power system is working according to the speed of your pedalling.
The faster you are pedalling, the stronger the electric power will be within its limit speed of 25km/h; if you're
not pedalling, the motor will stop.
When the motor starts to work, the power supply will enhance, and the bicycle can start more quickly.
