Build or replace a compatible rear-drive system with this complete 48V 1000W brushless hub motor wheel assembly and steel rear swingarm. The package combines a 12-inch rear motor wheel with an 80/100-12 off-road tire, reinforced swingarm, hydraulic hand-brake assembly, and mounting components for custom motorcycle and off-road vehicle projects. The rear hub motor is rated at 48V 1000W and features approximately 55-60Nm of torque. It has a rated current of 28A, maximum current of 42A, 10-pole magnet construction, and a 120° Hall sensor angle. Rated speed is approximately 655 ±25 RPM with a 1:5 gear reduction ratio. These specifications are intended for compatible rear-drive applications requiring strong low-speed output. The 12-inch rear wheel is fitted with an 80/100-12 off-road tire and includes a rear disc brake interface. The motor assembly uses a 175mm axle length and plug-in phase wiring. Motor wiring must be installed on the LEFT side. Confirm your original wiring arrangement and axle dimensions before installation. The included rear swingarm is constructed from welded steel with reinforced side structures and measures approximately 440mm / 17.3 inches overall. It is designed around compatible 10-12 inch rear wheel configurations and provides mounting locations for the rear wheel, suspension components, brake system, and related hardware. 1 × 48V 1000W rear brushless hub motor wheel. 1 × 80/100-12 off-road tire and 12-inch wheel assembly. 1 × Steel rear swingarm. 1 × Hydraulic hand-brake assembly. 2 × 6001 bearings. 1 × Oil/hydraulic brake mounting bracket.
