Hydraulic Brake Set for OUXI V8 / H9 E-Bikes with 160mm Rotors

OUXI V8 / H9 Brake Upgrade Hydraulic Brake Set for OUXI V8 & H9 with 160mm Rotors Dual-piston hydraulic brake upgrade with pre-filled mineral oil, aluminium levers and two 160mm rotors for compatible OUXI V8 and H9 fatbikes. Dual-Piston Hydraulic Calipers 160mm × 2 Disc Rotors Mineral Oil Pre-Filled System L + R Front / Rear Set V8 / H9 Target Models Hydraulic Upgrade More Controlled Braking with Less Lever Effort The dual-piston hydraulic calipers provide more progressive braking control than basic mechanical systems, while the pre-filled mineral-oil setup reduces installation preparation. Dual-Piston Caliper Hydraulic Pressure on Both Sides Dual-piston hydraulic calipers apply braking force more evenly across the rotor, helping deliver smoother modulation and stronger stopping control on heavier fat-tire e-bikes. Brake Lever & Hose Aluminium Levers, Pre-Filled Mineral Oil The system comes pre-filled with mineral oil and uses aluminium-alloy brake levers. The reference configuration uses left lever for the front brake and right lever for the rear. 160mm Rotor Set Two Rotors Included The package includes two 160mm disc rotors for front and rear use. Confirm your existing rotor diameter, caliper mount and adapter position before installation. Compatibility First Check Your V8 / H9 Version Before Ordering V8 2.0 / 3.0 and H9 platforms commonly share compatible hydraulic brake hardware, but OUXI generations differ. Do not order only by the model logo. 01 — Version Confirm V8 / H9 generation 02 — Rotor 160mm disc requirement 03 — Mount Caliper / adapter fit 04 — Hose Front & rear hose length 05 — Sensor Brake cut-off connector if fitted Model Compatibility Which OUXI Versions Use Hydraulic Brakes? OUXI brake configurations vary by market and generation. Use this as a reference, then verify your actual bike hardware. Model Typical Brake Setup Compatibility Note OUXI V8 1.0 Mechanical disc Upgrade requires careful fit check OUXI V8 2.0 / 3.0 Hydraulic on many versions Closest match to this replacement set OUXI H9 Hydraulic Verify rotor, hose and sensor details OUXI V8 4.0 / Pro Hydraulic Do not assume earlier V8 hardware is identical Installation Note Brake Installation Is a Safety-Critical Job After installation, confirm caliper alignment, rotor clearance, lever pressure, hose routing and fastener torque before riding. If hose shortening, bleeding or brake-sensor wiring is required, use a qualified bicycle technician.

Yes. The reference package includes one left/right hydraulic brake pair and two 160mm disc rotors. Is the system pre-filled? Yes. The reference brake set is pre-filled with mineral oil, although hose shortening or installation changes can still require bleeding. Will it fit every OUXI V8 or H9? No. Check model generation, rotor diameter, caliper mounting, hose length and any brake cut-off sensor connector before purchase. What brake pads does it use? The reference set uses resin-metal composite / semi-metallic style pads. Match pad shape to your caliper before ordering replacements.
