The Narrak S129 is a folding fat-tire electric bike with a 750W rear hub motor (1,100W peak), a 48V 13Ah battery and 4-inch tires. It folds for car, truck or RV transport and carries up to 280 lb on a step-thru or over frame with a front suspension fork. It runs four modes, including throttle and walk assist, and tops out around 28 mph. Against city folders it trades light weight for off-road traction and power; against full-size fat bikes it trades stability for portability.
