AIMA Big Sur All-Terrain E-Bike in White

Season:2024

Brand:Aima

Code:BigSurWhite

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.

❇️❇️❇️❇️❇️ 09/29/2024 - C. - Best bike ever

We have the black one and the white one. These bikes are beasts. We love riding and enjoying life. I love how it is well built. It feels very sturdy. They are big bikes. We have the 26”. Love how it rides and handles. Very comfortable. Just wish it would go 28 mph with the throttle.

❇️❇️❇️❇️ 09/20/2024 -Matt P - Love my Big Sur

I purchased in May and have ridden 900 miles. It would be more but I got creamed by a car that had ran a stop sign. Broke 4 ribs and my clavicle. I just got back on it after 35 days. The thing is built like a tank. Aside from a broken light, some cometic scrapes and scratches it seems to be no worse for the wear. I seems that my dealer is having a hard time getting parts however. Parts for the light have been on order for almost a month.

I’ve had my Big Sur for about a month now. It has taken me about that long to get it setup the way I prefer. I added a nice suspension seat post, handlebar riser, and handlebar extender to bring them closer to me. I love the feel of the bike, but I wish I could adjust the torque sensor so it’s harder to pedal. In order to get my heart rate up, I have to turn off the PA, then turn it back on. I wish there was an adjustment to lessen the ease of the PA. I’d also like to see signals added to the bike. The headlight seems to be a common issue. It doesn’t tighten, and it’s really big and bulky. A smaller, more powerful light would be better.

I tried riding my other bike, which is a cadence-sensored bike. It is hard going back to that smaller frame with Les’s suspensions. However, I burn more calories on that bike. I was hoping the torque sensor would require me to work harder and burn more calories.


❇️❇️❇️❇️❇️ - 04/09/2024 - Scott Reynolds - New Big Sur Owner

I bought the 26” Big Sur for myself and bought my wife another brand e-bike and she’s already wanting to take mine away. For a large and heavy bike the Big Sur rides and shifts smoothly. We rode 20 miles this weekend and are looking forward to getting back out soon. I love the big seat, fat tires, and the speed of the bike is awesome. It’s possible that I trade my wife’s bike in for another Big Sur. Great job AIMA!

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 own 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.
