Built for riders who want to go anywhere, the Big Sur is a 26" × 4" fat-tire all-terrain eBike powered by a 750W Bafang rear hub motor with a torque sensor that matches the motor output to your actual pedaling effort — no guessing, no lag. A 48V 15Ah LG M50LT 21700 battery provides 30–60 miles of range, and the full UL2849 certification means it's among the safest eBikes available. Large 203mm brake rotors, an 80mm suspension fork, a 52T crankset for stability at speed, and a custom AIMA Comfort XL seat make it built for real all-day riding.
