This step-through folding fat-tire electric bicycle is designed around comfort, utility, and everyday versatility. Its full-suspension system combines a hydraulic front fork with an adjustable rear air shock, while 20" × 4.0" Kenda fat tires help provide cushioning and traction across streets, beaches, and uneven paths.

A 750W sustained-output hub motor delivers up to 1400W peak power and works with a 720Wh removable battery for a stated maximum range of up to 90 miles. Torque-sensing pedal assist, hydraulic disc brakes, NFC start-up, integrated lighting, and a 440 lb total weight capacity round out its commuting and recreational capabilities.
