Best 20-inch folding fat tire bikes under $350

Top pick: SYX MOTO 20" Fat Tire Electric Bike — it's the only one here that ticks all three boxes on paper: a foldable 6061 aluminum frame, true 20" x 4.0 fat tires, and a 350W Bafang motor with a lockout suspension fork. Bafang is a known motor brand, which matters more than anything else at this price.

Who the others suit:

• UPlee GS5 — if you want the lowest spend and a folding e-bike; its listing is thin on specs, so confirm tire width before buying.
• GOTRAX F5 — a step-through folder rated to 300 lb with a claimed 60-mile range; best if easy mounting matters.
• Aostirmotor A20 — a 500W, 25 mph folder with a 36V 13Ah battery; the pick if you'll stretch the budget for more power.
• Ambifirner / Harmie 20" fat tire mountain bikes — non-electric fat-tire 20-inchers; fine for pedal-only riding, but they don't fold.

Skip the VIVI Gopina: it isn't a fat-tire 20" bike.
