Bicycle standards (as at 2011) are:
EN 14764 for city and trekking bikes
EN 14766 for mountain bicycles
EN 14781 for racing bicycles
EN 14872 for luggage carriers
RN 14765 for bicycles for young children
"The Commission does this by means of its Decision of 29 November 2011 on the safety requirements to be met by European standards for bicycles, bicycles for young children, and luggage carriers for bicycles pursuant to Directive 2001/95/EC.
With this Decision, the European Commission has now set a very first set of requirements that bicycles have to comply with in order to be conform with the EU General Product Safety Directive 2001/95/EC that “lays down an obligation on producers to place only safe products on the market.”
In addition, CEN standards are designed to ensure a minimal level of product quality and to strengthen consumer protection legislation. They contain safety requirements for the most important bicycles components like brake systems, transmission systems, handlebars, stems, frames & front forks and saddles.
These standards apply in all 27 EU member states. However, in the majority of member states there is no legal obligation to comply with the standards, they remain voluntary standards.
In most member states, manufacturers are allowed to prove compliance with these standards through self-certification. However, CEN, the European Committee for Standardization, does recommend the use of a test lab that is specifically accredited to test according to the standards"
