Ultimate Pre-Bled Super 73/Ridstar q20/Macfox Ultra Bee Rear Brake Kit (Ships Next Business Day)

Ultimate Super73 / Ridstar Q20 Ultra Bee Rear Brake Kit

Upgrade your ride with a powerful, complete rear braking solution designed for Super73 and Ridstar Q20 builds. This kit combines the proven stopping power of the Ultra Bee rear hydraulic brake with a precision CNC-machined mounting bracket and an upgraded oversized rotor for improved braking performance, control, and reliability.

Whether you’re replacing a stock setup or upgrading for better stopping power, this kit includes everything needed for installation and performance you can trust.

E-Bike Compatibility & Fitment

Our Ultra Bee Brake Kit works with a wide range of popular e-bike platforms, including Super73, Macfox, Ridstar, Zooz, Freego, and other bikes with similar brake configurations.

Compatible models include Super73 ZX, RX, and S2; Macfox X1, X1S, X2, and X7; Ridstar Q20, Q20 Pro, and E26; and Zooz Ultra Urban / UU models, along with many comparable e-bikes.

To simplify installation, the kit comes with a rear brake conversion mount that adapts the factory rear brake mounting location to the Ultra Bee setup. This allows for a clean, straightforward bolt-on installation without the need for major modifications.

Important Note for Macfox Owners

Certain Macfox models, particularly the X2 and X7, may need an additional adapter for proper fitment. Depending on your bike’s factory brake setup, the original brake post may need to be replaced with a standard 180mm post-mount brake adapter.

These adapters are inexpensive and easy to find at most bicycle shops or through online retailers. When shopping online, search for “180mm post mount brake adapter.”

For convenience, we also recommend a compatible option available on Amazon.
