Using these brake levers is easy. Just connect them to your cable brakes on your Bafang BBS01B, BBS02B, or BBSHD e - bike. When you need to stop, simply squeeze the levers gently to slow down or come to a full stop. Remember, these levers are only for cable brakes, so don't try to use them with hydraulic brakes. To keep them in good condition, regularly check the cables for any signs of wear or damage. Clean the levers with a soft cloth every now and then to remove dirt and grime. If you notice any issues with the braking performance, it's best to have them checked by a professional.
