For bicycles included in this section, in addition to the safety requirements in Section 1 further requirements shall apply as specified below.
The maximum saddle height and average weight limits are based on anthropometric data (average weight and length of legs according to age). For these bicycles, the following requirements shall apply:
no quick-release devices of any type shall be used,
toe straps and toe clips shall not be fitted,
the force of front brakes shall be limited to prevent loss of control of the bicycle due to blocking wheels,
it shall be possible to fit or remove stabilisers without releasing the fixing of the rear wheel axle,
bicycles for young children shall not pose a danger of entrapment in any possible position of the seat,
bicycles for young children shall be equipped with at least two independent braking systems, one on the front and one on the rear.
On mountain bicycles, all safety components shall be designed to withstand all forces that are higher during normal use than on other types of bicycles (e.g. vibration and knocks caused by rough roads, higher forces on the drive and steering components and brakes) and to withstand brake fading.
On racing bicycles, all safety components shall be designed to withstand all forces that are higher during normal use than on other types of bicycles (e.g. higher speed, higher force on the drive and steering components and brakes).
