Its all-terrain tread is designed for the higher speeds and loads an electric drivetrain adds.Fitment is the easy part here: 20×4.0 is the standard size on most folding and compact fat e-bikes. Editorial analysis of buyer reviews suggests owners of common folding e-bike models report straightforward mounting, though fat-tire beads are always stiffer than road tires, so bring tire levers and patience.**Flaws but not dealbreakers.** The aggressive all-terrain tread hums more on pavement than a street-oriented pattern, and it’s sold only in the 20×4.0 size, so 26-inch wheel owners are out of luck.Riding a 26-inch fat e-bike instead?
