Description
🚨 PLEASE GET SELECT A ROTOR SIZE OF 40MM LARGER THAN YOUR CURRENT ROTOR FOR OPTIMAL FITTING 🚨 What’s Included: * 1 × Pre-Bled Ultra Bee Rear Hydraulic Brake Assembly * 1 × Custom CNC-Machined Mounting Bracket * 1 × Upgraded 220mm or 240mm Heavy-Duty Rotor * All Required Installation Hardware The Ultra Bee Brake system is engineered specifically for e-bikes, including models like Super73, Macfox, and Ridstar. This pre-bled rear brake kit features a moto-grade design that enhances braking power for higher speeds and heavier loads. It is recommended to select a rotor approximately 40mm larger than the stock size for optimal performance. Please note: Some Macfox models — including the Macfox X2 and Macfox X7 — may require replacing the stock brake post with a standard 180mm post mount adapter. These are inexpensive and widely available at your local bike shop or online (search "180mm post mount brake adapter" on Amazon or similar).
