500W 48V Ebike Rear Hub Motor 85N·m 4.0" Fat Tire 170-175mm Dropouts

• 【500W 48V OEM-Grade Power】​ This brushless rear hub motor delivers a balanced 500W output on a standard 48V system—ideal for commuting, neighborhood rides, and light trail use. As a direct OEM-style replacement, it restores factory-level acceleration without drawing excessive amps, keeping your existing 48V battery efficient and cool.
• 【85 N·m Rated Torque】​ Engineered with 85 N·m of rated torque, this fat-tire hub climbs moderate hills and carries daily cargo smoothly. Unlike worn stock motors that feel sluggish under load, it brings back responsive throttle response—perfect for riders under 220 lbs on paved or packed surfaces.
• 【Built for 4.0" Fat Tires】​ Precision-matched to 4.0-inch wide fat-tire e-bikes with a 170–175mm rear dropout (O.L.D). Not a universal part—manufactured to factory specs so it drops into your existing rim and spokes. Verify your frame spacing before ordering; this is a fitment-specific component, not a one-size mod.
• 【Left-Side Cable / Disc Brake Ready】​ Comes with left-side cable exit (standard 9-pin L915 connector) for disc-brake fat bike frames. Need right-side exit? We also stock 910C/910 black connector versions—message us with your old motor photo to confirm fit. Plug-and-play for most 48V controllers.
• 【1-Year Warranty, Motor Only】​ Package includes 1x rear hub motor + cable. Rim, spokes, controller, and battery not included. Backed by 12-month support with dimension verification help. A cost-effective way to fix motor aging, bearing noise, or power loss—without buying a whole new wheel.
