Adjust the derailleur
Adjust the Fine-tuning nut or screw when the derailleur makes some abnormal sound.
The way to adjust the brake of the e-bike is the same as adjusting the bike. The most important thing is
effective braking and no blockage after braking and make sure the brake and the power brake function
are work well. Friction between road and tyre is reduced when raining, so besides concentration every
rider should brake gently in advance to keep away from danger. The following several advices are for
your reference when the brake doesn't work well or meets the handlebar when braking. Every screw
and nut should be tightened properly to make sure the wheel running flexible with no resistance.
Brakes
The brake-shoes which are fixed on the V-brake and Roller-brake wear out in time causing gap
widening between the brake-shoes and the rim flank. This is indicated by the increase of the leeway of
the brake lever.
The left brake lever controls the rear brake and the right brake lever controls the front brake.
You can modify by adjusting the brake-system through following steps: Simply turn the adjusting screw
on the brake lever until the gap between the brake-shoes and the rim flank averages about 1.5-2 mm.
Adjust the brakes correctly by tightening or loosening the crosshead screws on the side of the brake
arms, until the brake-shoes are centered to the rim. Through tightening of the screw, will the spring be
prestressed and the brake-shoe moved away from the rim.
