At just 54 lbs, the Key West is AIMA's lightest model — designed for riders who want an eBike they can actually throw around. A 500W Bafang motor with a torque sensor delivers smooth, responsive assist up to 28 MPH on pedal assist, and the BAFANG C010 TFT 4.0" display brings navigation, call/text alerts, and integrated turn signals to every ride. The 27.5" × 2.1" tires and rigid fork keep things nimble, while Tektro 203mm hydraulic disc brakes keep you in control. Perfect for beach rides, neighborhood cruising, and daily commutes.
