Bound was a British automotive brand established in 1920 by the Bound Brothers in Southampton. The company specialized in the production of a unique single-seater cyclecar, which was notable for its narrow design, measuring only 26 inches (660 mm) in width. This compact vehicle was powered by a 3.5 hp Precision engine and utilized a friction transmission system, reflecting the innovative engineering of the time.

The Bound cyclecar represented a niche segment of the automotive market during the early 20th century, catering to enthusiasts seeking lightweight and efficient vehicles. However, details regarding the brand's production timeline and subsequent developments remain limited.
