Big Sur is a 26 x 4” fat tire all-terrain e-bike equipped with a powerful 750W Bafang rear hub motor. Big Sur can quickly get you up to 28mph while pedaling, or 20mph if you just want to use throttle. Integrated lights, extra-large 203mm brake rotors, LG 21700 battery cells, and a full UL 2849 certification make Big Sur one of the safest e-bikes on the market. Sporting a large 52T chainring and a custom AIMA Comfort XL Saddle, the Big Sur keeps you stable at speed and provides a remarkably comfortable and smooth riding experience. Hub Motor and Battery Powered by a 48V 15Ah battery using LG high-capacity cells, Big Sur's 750W Bafang rear hub motor has the juice to take you just about anywhere. Torque Sensor One of the latest e-bike innovations, a torque sensor sees how hard you pedal in real time and matches your input power using the motor. This leads to a safer and more intuitive ride, as well as conserving battery life. Full Color Backlit LCD Display View essential stats at any time with a bright and daylight-ready full color screen.

Suspension Fork With up to 80mm of travel and adjustable preload and lockout settings, our suspension fork eats up everything in your path, assisted by Big Sur's 4" wide tires. Fender & Rear Rack An MIK HD rear rack comes standard, allowing for endless customization possibilities. Plus, fenders come pre-installed to ensure you're protected from below while riding in any weather conditions. Flat Position Welding We've taken great care and utilized some of the newest aluminum welding techniques available on our frame, which comes with a lifetime warranty. These techniques allow the frame to maintain its structural rigidity while also appearing flat and smooth.

Controller Compartment Big Sur's controller is mounted right near the pedals, allowing for easy access during repairs and maintenance. Plus, this mounting style allows the controller to utilize the entire frame as a heat sink, greatly improving safety and performance under load.

Flat Position Welding We've applied one of the most advanced aluminum welding processes to our frame, an exclusive "flat position welding" technique. This allows the frame to maintain its strength and rigidity while also appearing smooth and flat. Walk Assist Gone are the days of pushing your bike around by hand. Our walk assist function allows the bike to maintain ~2-3mph (walking speed) as you push it alongside you, up a hill, or anywhere else. Controller Compartment Mid-drive? Not quite!
