The Defender S is a full-suspension fat-tire e-bike built for comfortable rides on mixed terrain. It combines twin Bafang motors, a dual-battery design option, and long-range capability with practical components like hydraulic disc brakes, a thumb throttle, and a color display.
Benefits
Ride farther between charges — longer range options keep you on the trail or commute without frequent recharging.
Confident handling across surfaces — fat tires and full suspension absorb bumps and improve stability.
Smoother, safer stops — hydraulic disc brakes with motor cut-off sensors reduce stopping distance and improve control.
Simple control and visibility — thumb throttle and a clear color display make adjustments quick and easy while riding.
Easy setup and maintenance — includes manual and tools so you can get riding sooner.
