220mm Heavy Duty 2.3mm Floating Brake Rotor Kit

The EDBA 220mm Heavy-Duty Floating Brake Rotor Kit is an essential braking upgrade for electric dirt bike riders installing high-power controllers or 72V battery upgrades — providing the additional thermal mass needed to handle the increased deceleration loads that stock 180mm rotors cannot manage reliably. At 2.3mm thickness (27% thicker than standard 1.8mm bicycle rotors), these laser-cut stainless steel rotors resist thermal warping under sustained braking and dissipate heat 40% faster than thin rotors, ensuring consistent brake performance on long Australian downhill descents. The floating rotor design allows the steel rotor ring to expand freely under heat without transferring warping stress to the aluminium carrier. CNC aluminium caliper adapter brackets provide precise caliper alignment with both stock and aftermarket calipers. Available in a two-rotor front and rear kit configuration. A must-have upgrade alongside any electric dirt bike power or battery upgrade. Available from Electric Dirt Bike Australia.
