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.

 
Ride Further with Confidence. Enjoy up to 75 miles* on a single charge thanks to the upgraded 48V 20Ah battery — that’s 33% more range than our 1st Gen.

Quieter, More Efficient Power. Compared to our already whisper-quiet first-generation motor, the new 750W version cuts noise by another 10dB while improving energy conversion—delivering the same quick, powerful acceleration with even greater efficiency.

Effortless, Natural Pedal Assist. The torque sensor instantly reads your pedaling and adjusts motor output for seamless, natural assistance every time you ride.

Never Miss a Turn... or a Call. The larger 4.0” display keeps stats clear at a glance, with FindMy and Bluetooth connection so you can mirror navigation, calls, and messages from your phone through app.

Built Like a Tank. A reinforced frame stands up to rough terrain and daily use, delivering long-term reliability in any riding environment.

Confident Braking Power. 203mm hydraulic disc brakes provide strong, consistent stopping ability—even on steep hills or in wet conditions.
