EN71 Toys Bicycle VS Balance Bike

EN71 detail.
Toy bicycle:
Two-wheeled vehicle, with or without stabilisers, with a maximum saddle height of 435 mm or less and which is propelled solely by the muscular energy of the person on that vehicle, in particular by means of pedals, and which has either a free-wheeling mechanism or a fixed drive.

Free-wheeling mechanism:
Transmission in which the drive mechanism is disengaged from the driven shaft when the driven shaft rotates faster than the drive mechanism
NOTE An example of the use of a free-wheeling mechanism is a bicycle which is going downhill without the pedals moving. Without a free-wheeling mechanism the rear wheel would drive the pedals around.
Free Wheel Mechanism 
The definition clarifies that to have a free-wheeling mechanism, the vehicle must have a driven shaft. A balance bike does not have a driven shaft in the same manner as we mean on a bicycle.
