Transport ministry inspectors have warned nine different internet companies offering illegal fast fat bikes on the Dutch market that they face fines of €15,000 if they continue to do so.

The inspectors said at the end of last year that fines would follow if companies continued to sell bikes that have not been approved for use on Dutch roads. 

The fines focus on e-bikes with thick tyres and pedals, and which are capable of travelling at speeds of over 25 kph. 

“This is about traffic safety,” said Karin Visser, the inspectorate’s monitoring chief. “Lots of young fat bike users don’t realise that they are classed as a moped, not an electric bike. And that means a driving licence, number plate, helmet and insurance are compulsory.” 

The users themselves can also be fined up to €1,400 for not meeting road safety requirements. 

Fifteen of the sellers warned by the inspectors last year have withdrawn their products from sale.
