Big Sur 2.0 is a versatile fat-tire e-bike built for both daily commuting and off-road riding. Powered by a 750W Bafang rear hub motor and a refined 48V battery system, it delivers strong acceleration, dependable hill-climbing performance, and extended riding range. Its UL2849-certified electrical system, hydraulic disc brakes, front suspension, and 26" x 4" all-terrain tires provide confident handling and comfort across a variety of surfaces. Compared to the original model, the Big Sur 2.0 features upgraded ergonomics, smoother power delivery, and improved system integration for a more refined overall riding experience.
