WASHINGTON (BRAIN) — Pedego is recalling about 400 electric Fat Tire Trikes because the aluminum frame can develop a hairline fracture near a weld, causing the tubes to separate and posing fall and laceration hazards.The brand has received 16 reports of frame breakage, including one where a rider’s leg was lacerated. The Fat Tire Trike has a rectangular label on the downtube near the front of the frame with the word “Pedego” printed. The product was sold in matte black.

Well, in this instance fat tire bike is the name of the bike itself.
But mostly from personal experience it massively improves the ride and feel of a
bike. Mine has fat 20" tires and the ride is smoth and can deal with bumps and rough terrain with ease all while feeling roughly the same as asphalt.
