Fat Tyre Ultra Bee Brakes - Rear Brakes

Ultra Bee Brake Upgrade Kit for Super73, Ridstar, Macfox, Fatboy, DiroDi Etc.

Upgrade your stopping power with a serious brake setup built for riders who want more control, more confidence, and a much stronger feel than standard factory brakes.

These Ultra Bee brakes are a popular upgrade for Super73-style and e-moto-style bikes, especially for heavier builds, faster setups, and riders who want better braking response on the road, trails, or daily rides. Whether you ride a Super73, Ridstar, Macfox, Fatboy, DiroDi, or a similar electric bike, this upgrade gives your bike a more powerful and reliable braking feel.

Factory brakes can feel weak once you start adding speed, weight, bigger batteries, upgraded controllers, passengers, or off-road riding. This brake upgrade is designed to give you improved bite, smoother control, and stronger stopping performance when you need it most.

Key Features

• Stronger braking performance compared to many stock e-bike brake setups
• Better control and confidence at higher speeds
• Ideal for upgraded or heavier e-bike builds
• Great for Super73, Ridstar, Macfox, Fatboy, DiroDi and similar frames
• More aggressive brake feel for street, trail and everyday riding

Why Upgrade?

If your stock brakes feel soft, underpowered, or sketchy when riding faster, this is one of the most important upgrades you can make. Better brakes don’t just improve performance, they make the whole bike feel safer, sharper and more controlled.

Perfect for riders who have upgraded their power system, ride in traffic, carry extra weight, or simply want a brake setup that feels more capable than the standard factory option.
