AIMA Big Sur Sport 20″ Ebike

Everything you love about the original Big Sur is back! Now sporting 20" x 4" fat tires, Big Sur Sport is smaller and lighter, but it's just as fun and performant as Big Sur 26", if not more so! This bike retains the original's class 2/3 rating (20mph and 28mph top speed using the throttle and PAS respectively), as well as its safety features, including big 203mm brake rotors, LG 21700 battery cells, and a full UL2849 certification. Equipped standard with the AIMA Comfort XL seat and an MIK rear rack, Big Sur Sport delivers the same level of power, comfort, and smoothness of its bigger brother.

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Rather than relying on an outdated cadence sensor to detect your movement, our torque sensor is able to instantly feel how hard you're pedaling at any given time and instruct the motor to match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.
