For front wheel installations the distance between the front fork dropouts should be approximately 95-100mm. The fit should be very tight. Sometimes a small layer of paint may have to be removed just from the inside surfaces to fit the hub motor wheel.
Rear wheel kits 135mm approx. dropouts. For wider rear dropouts (Fat bikes and other customs) visit our website.
This dropout clearance is standard for most bikes. If your front fork dropouts are very close to being the right measurements, usually some minor persuasion is all that is required to achieve the fit, the tighter the better.
If you own a 20” folding bike with narrower front forks (80mm clearance instead of 100mm) you will have to visit our website for information on the correct kit.
