👉 Motorcycle frame in the context of Underbone

An underbone is a type of motorcycle that uses structural tube framing with an overlay of plastic or non-structural body panels and contrasts with monocoque or unibody designs where pressed steel serves both as the vehicle's structure and bodywork. Outside Asia, the term underbone is commonly misunderstood to refer to any lightweight motorcycle that uses the construction type, known colloquially as step-throughs, mopeds or scooters (see Scooter (motorcycle)).

An underbone motorcycle may share its fuel tank position and tube framing, along with fitted bodywork and splash guards with a scooter while the wheel dimensions, engine layouts, and power transmission are similar with conventional motorcycles.

Motorcycle frame in the context of Moped

A moped (/ˈmoʊ.pɛd/ MOH-ped) is a type of small and inexpensive motorcycle, generally having a less stringent licensing requirement than full motorcycles or automobiles. Historically, the term exclusively meant a motorcycle with bicycle pedals. Mopeds typically travel only slightly faster than bicycles on public roads.

Traditional mopeds are distinguishable by their pedals, similar to a bicycle. Some mopeds have a step-through frame design, while others have motorcycle frame designs, including a backbone and a raised fuel tank, mounted directly between the saddle and the head tube. Some resemble motorized bicycles, similar to modern ebikes. Most are similar to a regular motorcycle but with pedals and a crankset that may be used with or instead of motor drive. Although mopeds usually have two wheels, some jurisdictions classify low-powered three- or four-wheeled vehicles (including ATVs and go-karts) as a moped.
