Mountain pass cycling milestones are signposts that provide cyclists with information about their current position with regard to the summit of the mountain pass. They always provide information for cyclists going uphill. Sometimes the signs are two-sided, thereby providing information also for cyclists going downhill.

Cycling infrastructure is all infrastructure cyclists are allowed to use. Bikeways include bike paths, bike lanes, cycle tracks, rail trails and, where permitted, sidewalks. Roads used by motorists are also cycling infrastructure, except where cyclists are barred such as many freeways/motorways. It includes amenities such as bike racks for parking, shelters, service centers and specialized traffic signs and signals. The more cycling infrastructure, the more people get about by bicycle.
