Product Description

The EUNORAU DEFENDER S 2.0 is a dual-motor, full-suspension fat-tire electric bike built for riders who move between pavement and less predictable ground. A 750W hub motor at each wheel delivers 1,500W of combined rated power and all-wheel-drive traction, so both wheels keep driving when the surface turns loose, soft, or uneven. The bottom-bracket torque sensor reads how hard you pedal and matches assistance to your effort, giving gentler support under light pressure and more power when you push harder.

A 6061 aluminum four-bar frame pairs a 75mm-travel front fork with an adjustable air rear shock to manage roots, ruts, and repeated impacts, while 26 x 4.0-inch fat tires spread a wide contact patch across gravel, sand, and snow. The 48V 17Ah removable battery supports up to 40 miles per charge, and Shimano CUES 9-speed shifting, 203mm hydraulic disc brakes with motor cut-off sensors, a color display with Bluetooth, and an integrated front light with horn round out the build.
