29、orewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a tec
30、hnical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters o
31、f electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document
32、 was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such p

38、re that bicycles manufactured in compliance with this International Standard 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
39、 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.For the purposes of improving repeatability and reproducibility and co
40、nsidering the applicability to all types of bicycle and the size and influence of the operator, the machine test method reflects todays 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, this method will be made
41、informative for the next revision. Users of this International Standard are invited to provide their feedback to ISO/TC 149/SC 1.vi ISO 2015 All rights reservedBS EN ISO 4210-2:2015Cycles Safety requirements for bicycles Part 2: Requirements for city and trekking, young adult, mountain and racing bi
42、cycles1 ScopeThis part of ISO 4210 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 manufacturers instructions on the use and care of such bicycles.This part of IS
43、O 4210 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 (see Table 1 and Figure 1).This part of ISO 4210
44、 does not apply to specialized types of bicycle, such as delivery bicycles, recumbent bicycles, tandems, BMX bicycles, and bicycles designed and equipped for use in severe applications such as sanctioned competition events, stunting, or aerobatic manoeuvres.NOTE For bicycles with a maximum saddle he
45、ight 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.Table 1 Maximum saddle height Dimensions in millimetresBicycle typeCity and trekking bicyclesYoung adult bicycles Mountain bicyclesRacing bicyclesMaximum saddle height635 o
