This page lists notable bicycle brands and manufacturing companies past and present. For bicycle parts, see List of bicycle part manufacturing companies.
Many bicycle brands do not manufacture their own product, but rather import and re-brand bikes manufactured by others (e.g., Nishiki), sometimes designing the bike, specifying the equipment, and providing quality control. There are also brands that have, at different times, been manufacturers as well as re-branders: a company with manufacturing capability may market models made by other (overseas) factories, while simultaneously manufacturing bicycles in-house, for example, high-end models.
Only brands or manufacturers that are notable as a bicycle brand should be included. If no page exists for the company or brand, then the page to be linked to should be created first or a reference provided as to its notability or the entry will probably be removed.
