Check the Dropout
Dropout width: Check the width of your bike's rear dropouts where the wheel attaches to the frame.Bafang rear hub motor wheels typically require a dropout width of 135mm, 138mm or 142mm, depending on the specific model. Measure the distance between the inner surfaces of the dropouts to confirm if it matches the required width.
