The test
35、s 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 s
36、tandardization of components.If the bicycle is to be used on public roads, national regulations apply.

The
44、 masses are given in Table 1.Drive the shaft at a speed not exceeding 100 min1for a total of 100 000 revolutions. If the pedals are provided with two tread surfaces, they shall be turned through 180 after 50 000 revolutions.Table 1 Masses on pedalBicycle typeCity and trekking bicyclesYoung adult bic
