This European Standard specifies safety and performance requirements for the design, assembly, and testing of bicycles and sub-assemblies intended for use on public roads, and lays down guide lines for instructions on the use and care of such bicycles.This European Standard applies to bicycles that have a maximum saddle height of 635 mm or more and that are in-tended for use on public roads.This standard does not apply to mountain bicycles and racing bicycles, tradesman's delivery bicycles, recumbent bicycles, tandems and bicycles designed and equipped for use in sanctioned competitive events.NOTE For bicycles with a maximum saddle height of 435 mm see EN 71 and with a maximum saddle height of more than 435 mm and less than 635 mm see EN 14765.
