Brake Levers or Hydraulic Brake Sensor
The kit will work with or without the brake sensors plugged in. The Bafang kit does not come with brake sensors, you can select the brake levers option made for standard cable actuated brakes. You also have the option of getting magnet sensors which allows you to adapt your existing brakes.
Confirm The Measurement
Before choosing a kit, a simple measurement is a must to avoid returns due to improper sizing and to give the customer a better understanding of the product size.
Chain Wheel Size For Free
Varstrom offers 5 kinds of chainring, Accolmile 36T chain wheel without guard and Bafang chainring with guard (44/46/48/52T). But what do they mean? This is an old question about Power or Speed. The less teeth chain wheel you use, the more power your bike will get from the motor. If you often ride on flat road and want higher speed, choose 52 teeth chainring.
