Big Sur is a 26 x 4” fat tire all-terrain e-bike, equipped with a powerful 750W Bafang rear hub motor. Big Sur is Class 2/3, meaning it'll take you up to 20mph using the throttle, and 28mph while pedaling, a torque sensor provides instant intuitive responsiveness. A specially-designed big headlight, extra-large 203mm brake rotors, LG 21700 battery cells, and a full UL2849 certification make Big Sur one of the safest e-bikes on the market. Sporting a bigger 52T crankset for stability at speed and a custom AIMA Comfort XL seat, Big Sur provides riders with a remarkably comfortable and smooth riding experience.
