Important Fitment Notes

Some E-Bike models including some of the Macfox models require replacing the stock brake post with a standard 180mm post mount adapter for correct fitment onto the rotor.

If your e-bike encounters this issue, here is a link to purchase a proper fitting mount: https://www.amazon.com/dp/B08D9JRTGB?th=1

Ultra Bee Brakes require the brake disc that is ~40mm wider than the stock rotor. For example, if your current rotor measures 180mm in diameter (this is the most common stock rotor size) please select the 220mm rotor. Apply this method to your current rotor size to guarantee fitment.
