About the Rotors
Note: All the above rotors can be used on your BeeCool ebikes as all BeeCool ebikes are equipped with 180mm rotors. Theoretically, all 180mm rotors can be used on our ebikes; the only difference is their different outlook design.

1) Bike rotors are consumables, so when your rotors are bent, broken, or worn out, you need to replace them immediately. 
2) Do maintain your ebikes regularly to find out the worn-out parts and replace them in time.
