Best fat-tire electric bikes for adults

Top pick: Aipas M2 Pro Xterrain — it's the one bike here that's both a true fat-tire machine and rated for 36+ mph, so 30 mph is cruising rather than a stretch. A 1,800W motor with a throttle, strong owner ratings, and it's the best value of the fast bikes.

Who the others suit:

• Aipas M1 Pro Xterrain ST — same family, full suspension and a step-through frame; easier to mount and softer on rough ground, but slower.
• Kingbull Hunter 2.0S — fat tires, steel frame, hydraulic brakes and excellent ratings; a solid trail-first choice if you don't need 30 mph.
• Hiboy P6 / Kepler 52V — the Kepler has the longest range and a big peak motor; the P6 is the lighter, simpler fat-tire commuter.
• FREESKY 4000W — huge power and battery for the money, but it's not a fat-tire build.
• Coswheel R19 — genuinely fast, but not fat-tired and poorly rated.

If 30 mph is non-negotiable, the M2 Pro is the only one I'd buy.
