Aima Big Sur Sport

Everything you love about the original Big Sur is back and in the Aima Big Sur Sport! 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, it also delivers the same level of power, comfort, and smoothness of its bigger brother.
