A chopper is a type of custom motorcycle which emerged in the US state of California in the late 1950s. A chopper employs radically modified steering angles and lengthened forks for a stretched-out appearance. They can be built from an original motorcycle which is modified ("chopped") or built from scratch. Some of the characteristic features of choppers are long front ends with extended forks often coupled with an increased rake angle, hardtail frames, very tall "ape hanger" or very short "drag" handlebars, lengthened or stretched frames, and larger than stock front wheels. The "sissy bar", a set of tubes that connect the rear fender with the frame, and which are often extended several feet high, is a signature feature on many choppers.

A fatbike is an off-road bicycle with oversized tires, typically 3.8 in (97 mm) or larger and rims 2.16 in (55 mm) or wider, designed for low ground pressure to allow riding on soft, unstable terrain, such as snow, sand, bogs and mud. Fatbikes are built around frames with wide forks and stays to accommodate the wide rims required to fit these tires. The wide tires can be used with inflation pressures as low as 340 hPa; 0.34 bar (5 psi) to allow for a smooth ride over rough obstacles. A rating of 550–690 hPa; 0.55–0.69 bar (8–10 psi) is suitable for the majority of riders. Fatbikes were invented for use in snow and sand, but are capable of traversing diverse terrain types including snow, sand, desert, bogs, mud, pavement, or traditional mountain biking trails. The sport is sometimes referred to as fatbiking or fat-tire biking.
