velgrem

Velgrem is a Norwegian term used in some technical writings to refer to a wheel-related belt-drive arrangement. The word is a compound of velg (rim) and rem (belt). In practice, velgrem does not denote a single universal configuration; rather, it appears in historical or niche contexts to describe belt-driven wheel assemblies where a belt transmits motion to a wheel rim or to a wheel-mounted pulley. The usage is not standardized and the term is not common in contemporary automotive or bicycle engineering.

The etymology reflects its component words: velg meaning rim and rem meaning belt or strap. In Norwegian manuals from the early to mid-20th century, velgrem occasionally appears alongside other belt-drive terminology, sometimes treated as synonymous with belt-driven rims or rim-mounted drives.

Historically, belt-drive systems on bicycles and small machines used a belt to connect a power source to a wheel or to rotate the wheel via a rim interface; in most modern contexts these systems have been supplanted by chain drives or direct-drive configurations. Consequently, velgrem is now chiefly of historical or philological interest, appearing in technical glossaries, older catalogs, or descriptive texts rather than active engineering practice.

In current usage, engineers prefer more precise terms such as belt drive, pulley drive, rim-driven motor, or hub motor, depending on the exact mechanism. Velgrem may still be encountered in linguistic discussions or regional manuals that preserve older Norwegian terminology.
