Standard [WITHDRAWN] 2015-01
ISO 4210-2 specifies safety and performance requirements for the design, assembly, and testing of bicycles and sub-assemblies having saddle height as given in Table 1, and lays down guidelines for manufacturer´s instructions on the use and care of such bicycles. This document applies to young adult bicycles with maximum saddle height of 635 mm or more and less than 750 mm, city and trekking bicycles, mountain bicycles, and racing bicycles that have a maximum saddle height of 635 mm or more including folding bicycles. This document does not apply to specialized types of bicycle, such as delivery bicycles for traders, recumbent bicycles, tandems and bicycles designed and equipped for use in severe applications such as sanctioned competition events, stunting, or aerobatic manoeuvres. For bicycles with a maximum saddle height of 435 mm or less, see ISO 8124-1, and with a maximum saddle height of more than 435 mm and less than 635 mm, see ISO 8098. This International Standard has been developed in response to demand throughout the world, and the aim has been to ensure that bicycles manufactured in compliance with this 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, demanding high quality throughout, and consideration of safety aspects from the design stage onwards. The scope has been limited to safety considerations and has specifically avoided standardization of components. If the bicycle is to be used on public roads, national regulations apply and the bicycle can be equipped with a lightning system. Statement of WG 9 regarding the test methods for the braking performance: For the purpose of improvement of repeatability and reproducibility, and considering the applicability to all types of bicycle and the size and influence of the operator, the machine test method reflects today´s state of the art and is preferred to the track test method. Unless there is evidence of improvement of the test track method in the future, make this method informative for the next revision. Users of this International Standard are invited to provide their feedback to the ISO/TC 149/SC 1. The body responsible for this standard is NA 112-06-01 AA "Fahrräder für allgemeine und sportliche Benutzung" ("Cycles for common and athletic use") at DIN.
