DEFENDER S 2.0/Hunter X6

DEFENDER-S 2.0 — Dual-Motor Full-Suspension Fat-Tire E-Bike Built for challenging terrain and all-season exploration, the DEFENDER-S 2.0 combines dual-motor traction, responsive torque-sensing assist, and a four-bar full-suspension frame. Two 750W hub motors provide confident all-wheel-drive support, while the 48V 15Ah battery supplies the energy needed for demanding rides. Wide 26" × 4.0" fat tires, hydraulic disc brakes, and a Shimano 9-speed drivetrain help you stay in control across hills, loose surfaces, and uneven trails. Dual-Motor All-Wheel Drive A 750W hub motor at each wheel provides a combined rated motor output of 1,500W. Power is delivered to both the front and rear wheels, improving traction and giving you additional support when climbing or riding over loose terrain. Natural Torque-Sensing Assist The torque sensor responds to how hard you pedal and adjusts motor assistance accordingly. Pedal lightly for gentle support or apply more pressure when you need additional power, creating a smoother and more intuitive riding experience. Four-Bar Full Suspension The four-bar suspension design helps isolate bumps and maintain better wheel contact over uneven terrain. A suspension fork at the front and an air shock at the rear work together to improve comfort, stability, and control. 48V 15Ah Battery The 48V 15Ah battery uses high-capacity 21700 cells and is designed to support the demands of the dual-motor system. Estimated Range: Up to 40 miles / 64 km per charge 26" × 4.0" Fat-Tire Stability Wide fat tires provide a larger contact area for enhanced grip and stability. They help the bike maintain control across gravel, dirt, sand, snow, and other loose or uneven surfaces. Smooth 9-Speed Shifting The Shimano 9-speed drivetrain gives you a practical range of gears for climbing, cruising, and adapting to changing terrain. The handlebar-mounted shifter makes gear changes quick and convenient. Confident Hydraulic Braking Front and rear hydraulic disc brakes are paired with large 203mm rotors for controlled stopping performance. Integrated motor cut-off sensors immediately interrupt motor assistance when either brake lever is engaged. Clear, Connected Controls The handlebar-mounted display provides convenient access to pedal-assist and speed settings. Bluetooth functionality supports compatible connected features, while the integrated front light and horn add everyday convenience.
