34、hroughout Europe, and the aim has been to ensure that bicycles manufactured in compliance with it will be as safe as is practically possible. The tests have been designed to ensure the strength and durability of individual parts as well as of the bicycle as a whole, de- manding high quality througho
35、ut and consideration of safety aspects from the design stage onwards. The scope has been limited to safety considerations, and has specifically avoided standardisation of components. If the bicycle is used on public roads national regulations apply. No requirements on lighting equipment, reflectors
36、and warning devices are specified in this European Standard, due to the existence of several different national regulations applicable in the European Countries.

This European Standard applies to bicycles that have a maximum
38、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, tradesmans delivery bicycles, recumbent bicycles, tandems and bicycles designed and equipped for use in sanctioned competitive events.
