Stop with confidence. The Bair Bikes Disc Brake Rotor is a quality replacement disc brake rotor designed for electric bikes and compatible bicycles — delivering reliable, consistent stopping power ride after ride, even under the increased demands that e-bike speeds and weights place on your braking system.

Disc brake rotors are a critical safety component on any e-bike. Over time, rotors wear down, warp, or become contaminated — leading to reduced braking performance, squealing, and longer stopping distances. Replacing a worn rotor with a quality 180mm disc restores full braking confidence and keeps your e-bike performing safely on every ride, whether you're navigating busy streets, descending hills, or riding on mixed terrain along the Surf Coast.

The rotor size is commonly found on mountain bikes, hybrid bikes, and a wide range of electric bikes — offering a strong balance of powerful braking and heat dissipation for demanding riding conditions.

Key Features:

• 180mm diameter — compatible with a wide range of e-bikes, mountain bikes, and hybrid bikes
• 160mm diameter — compatible with a wide range of e-bikes, mountain bikes, and hybrid bikes
• High-quality steel construction for consistent, reliable braking performance
• Excellent heat dissipation to maintain braking power on long descents and demanding terrain
• Compatible with most standard disc brake callipers and hub mounting standards
• Corrosion resistant finish — built to handle coastal conditions, rain, and salt air
• Precise machining for smooth, quiet, and consistent pad contact
• Compatible with all Bair Bikes disc brake e-bike models

When Should I Replace My Brake Rotor? Replace your rotor if you notice any of the following — reduced braking power, squealing or grinding noises, visible warping or scoring on the rotor surface, or if the rotor has worn below the minimum thickness marked on the rotor edge. When in doubt, bring your e-bike in to the Bair Bikes team in Torquay for a brake check.

Best Paired With: For a complete brake service, pair with fresh brake pads compatible with your calliper type. A well-maintained braking system is the single most important safety feature on your e-bike — don't leave it to chance.

Who It's For: E-bike owners, mountain bikers, and hybrid cyclists who need a reliable quality replacement rotor to restore full braking performance and keep their ride safe on every outing.

Powerful, consistent, reliable — because stopping safely is non-negotiable on an e-bike.
