Features
Hub Motor and Battery
There's few places you can't go with Big Sur Sport, thanks to its powerful 750W (nominal) rear hub motor by Bafang paired with a 48V 15Ah high-capacity battery.
Torque Sensor
Rather than relying on an outdated cadence sensor to detect your movement, our torque sensor is able to instantly feel how hard you're pedaling at any given time and instruct the motor to match your performance, improving safety and efficiency.
Full Color Backlit LCD Display
Everything you need is right in front of you at all times, including your current speed, battery remaining, distance traveled, and much more.
20” x 4” Fat Tires
20” x 4’’ tires enable you to traverse any terrain with ease while retaining the nimble feeling of a 20" tire. It's the best of both worlds!
Suspension Fork
Offering 80mm of travel and adjustable preload & lockout functionality, our suspension fork provides a smooth and comfortable ride feel throughout a wide variety of riding conditions.
Fender & Rear Rack
Fenders come pre-installed to ensure you'll be able to tackle all sorts of weather conditions. Plus, an included MIK HD rear rack means there's no limit to what you can take with you.
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! Our mid-mounted controller cavity allows for streamlined assembly and repair, while also bolstering the controller's heat dissipation capabilities, improving the bike's performance and safety.

Customer Reviews
After I got a new bike Aima Big Sur Sport. from E-Bike Premier 18247 Parthenia St Northridge, CA 91325, I wanted to take a moment to express my gratitude for the exceptional customer service I received from Aima Big Sur. When I had a question about my new electric bike, the Aima support team went above and beyond to help me. They answered me right away and gave me their name, the one I was dealing with. I also had questions about setting up the screen and the Aima support team put me in touch with the main manager of JW . JW manager he contacted me and he promised me and did everything that I was interested in and had any questions I am very grateful to him for that. They were prompt, professional, and incredibly helpful, making sure I had all the information I needed to get the most out of my bike. They are very honest with clients if they promised they did everything.
It’s clear that Aima Big Sur truly cares about its customers, and their commitment to providing excellent support is greatly appreciated. Thanks to their outstanding service, I feel even more confident in my purchase and am thoroughly enjoying my bike. Keep up the great work, and I look forward to recommending your bikes to others!
Was looking for a step through bike now that I’m getting a bit older and stumbled upon the Aima bikes at a local dealer. Absolutely loved the quality, components, and the test ride. I was torn between the Santa Monica and the Big Sur Sport so I ended up buying both. Took our first 20 mile ride with my wife on the Santa Monica and me on the Big Sur Sport. The wife was in PAS 2 and I was in PAS 1. Flat ground and both riding the same speed. When we got home the Santa Monica had 65% battery left and the Big Sur Sport only had 43% remaining. I was a bit disappointed in that since the Web Site claims that both bike get up to 60 miles range ( I understand many variables involved). Other than the poor range of the Big Sur Sport, these are quality bikes.
Just got the Sport for my 5’3” wife during the Black Friday sale. She loves the bike but felt like the throttle was a little too intense and jumpy. The dealer did a firmware update that reduced the throttle intensity by 30%…much better. She also felt like she was reaching for the handlebars even though I rolled them back and moved her seat forward. So, I reversed the stem and remounted the handlebars which moved the handlebars back a few inches….perfect…happy wife. Great bike, much smoother torque converter than my Mokwheel…I’m jealous!
After conducting numerous grueling test rides, I arrived at the conclusion that the AIMA brand truly stands out as an exceptional choice for a big Sur sport e-bike. Having ridden it for a month now, I can confidently say that I adore every moment spent on it. In eco mode, I consistently achieve an impressive range of at least 60 miles on a full charge, making it perfect for my long rides. Along the way, I've received countless compliments from passersby, which only adds to the thrill of the experience.
Bought about a month ago. Very well made and rides so smooth. My first e-bike and glad I bit the bullet. So much fun and easy to ride.
