— Dune Dawgz Racing
Add a second rear brake caliper to your Ridstar with the Dune Dawgz Dual Caliper Mount.
Designed to replace the original single-caliper mounting bracket, this heavy-duty mount is designed for use with a 220/240 mm rear brake rotor and allows you to run two Ultra Bee brake calipers—keeping your existing hand-operated rear brake while adding a second caliper for a foot-operated brake setup.
Constructed from ¼-inch steel, this mount replaces the original aluminum bracket and provides mounting positions for both calipers.
Features
Dual-Caliper Setup: Accommodates two Ultra Bee rear brake calipers.
Hand + Foot Brake Configuration: Keep your existing hand brake and add a separately operated foot brake.
220/240 mm Rotor Compatibility: Designed for use with a 220/240 mm rear brake rotor.
¼-Inch Steel Construction: Built from solid steel plate.
Direct Bracket Replacement: Replaces the existing single-caliper mounting bracket.
Additional E-Bike Compatibility
The DDR Dual-Caliper Brake Mount features 51 mm center-to-center frame mounting-hole spacing, consistent with the International Standard (IS) disc brake mounting pattern used on many e-bikes.
In addition to Ridstar applications, similar rear brake mounting configurations are found across models sold by Super73, Macfox, Freego, Zooz, YVY, and other manufacturers.
Fitment on additional makes and models has not yet been verified by DDR. Compatibility depends on the exact frame mounting configuration, 220/240 mm rotor size and positioning, brake calipers, and available clearance.
If you own another brand of e-bike and are interested in this mount, please contact us with your bike's make, model, year, and photographs of your existing rear brake mounting bracket so we can help assess potential fitment.
Finish Options & Custom Powder Coating
Make it yours! Go raw, keep it classic in black, or add a splash of color to match your ride! Choose the finish that fits your style.
Raw Steel – Make It Your Own! Want to customize it yourself? Your mount will ship unfinished, giving you a blank canvas to paint, powder coat, or create your own one-of-a-kind look.
Black Enamel – Keep It Classic! Can't go wrong with black! Your mount comes finished with a durable black enamel paint coating for a clean, sleek look that's ready for your build. A great option for riders who want a finished bracket without the added cost of powder coating.
Custom Powder Coating – Stand Out! Want something that really pops? Give your mount a personalized powder-coated finish to complement your bike! Whether you're matching your frame, adding an accent color, or going for something completely different, make your ride uniquely yours!
Please Note: Custom powder-coated colors may require an additional 7–10 days of processing time before shipment. Raw steel is shipped uncoated and should be protected from moisture to prevent rust. Painted finishes may scratch or chip during installation or use.
What's Included
Please Note: This listing is for the caliper mounting bracket only. Brake calipers, foot brake pedal, master cylinder, hydraulic lines, and additional brake components are sold separately. Installation requires compatible brake components.
Fitment Notice: Please be aware that manufacturing tolerances and quality control can vary among e-bike manufacturers. As a result, slight differences in fitment may occur from bike to bike, even between identical makes and models. Minor adjustments may be necessary during installation. Always verify proper fitment and alignment before use.*
