AIMA Big Sur Sport 20" Fat Tire 750 Watt Motor Electric Bike
The Big Sur Sport features everything that the original Big Sur 26" e-bike does, just into a smaller frame. With a smaller wheel, your balance and stability is closer to the ground, and those smaller tires make this bike very nimble and maneuverable. 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.
