26" Fat-Tire 48V/52V 1500W Rear Hub Motor Kit

26" Fat-Tire 48V/52V 1500W Rear Hub Motor Kit

Complete 26 × 4.0" fat-bike rear hub kit: 1500W gearless motor on a 26 × 3" double-wall rim, 18-MOSFET 40A controller, LCD and twist throttle.

1500W brushless gearless rear hub, laced to a 26 × 3" double-wall rim for 4.0" tires
Two frame widths: 170 mm or 190 mm rear spacing
Freewheel or cassette version
48V/52V 18-MOSFET controller, 40A max current
LCD, twist throttle, brake levers, cruise switch and PAS sensor in the box

Fat bikes have wide rear ends that standard hub kits do not fit. This kit is built specifically for them, with a motor axle for 170 mm or 190 mm spacing and a wide 26 × 3” rim ready for 4-inch tires.

It ships as a complete system — motor wheel, controller, display and controls — so a dealer can convert a beach or snow bike without sourcing parts separately.
