AIMA BIG SUR ELECTRIC BICYCLE

remarkably comfortable and smooth riding experience

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 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.

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. Choose between several different themes to see your speed, battery life, pedal assist level, and much more.

26” x 4” Fat Tire

Big Sur's puncture-resistant 26" x 4" tires can handle almost any terrain, giving you the confidence you need to push your riding limits off-road.

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.

Walk Assist

Walk your bike alongside you, up a hill, or anywhere you need to with Walk Assist, which allows the bike to maintain a constant ~2-3mph based on your walking speed.

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.
