This European Standard specifies safety and performance requirements for the design, assembly and testing of BMX bicycles and sub-assemblies intended for use in any type of location such as roads and/or tracks and/or ramps. It applies to specialised types of bicycle designed and equipped for activities such as acrobatic ground manoeuvres, stunting and aerobatic manoeuvres and lays down guidelines for instructions on the use and care of such BMX bicycles. It applies to BMX bicycles on which the saddle height can be adjusted to provide a minimum saddle height of 435 mm or more. It applies to: category 1, BMX designed for a rider mass of 45 kg or less; category 2, BMX designed for a rider mass more than 45 kg. It does not apply to BMX bicycles for use in sanctioned competition events. No requirements on lighting set, reflectors and warning devices are specified in this European Standard due to the existence of several different national regulations applicable in the European countries.
