Experts say souped-up e-bikes pose big risk for children aged from 12 to 15, who account for many A&E cases

On a busy lunchtime, thick-tyred electric bikes zoom through the leafy lanes of the Vondelpark in Amsterdam. But after a marked rise in accidents – particularly involving children – these vehicles the Dutch call “fatbikes” are to be banned in some parts of the Netherlands.

“It’s nonsense!” said Henk Hendrik Wolthers, 69, from the saddle of his wide-tyred, electric Mate bike. “I drive a car, I ride a motorbike, I’ve had a moped and now I ride a fatbike. This is the quickest means of transport in the city and you should be able to use it.”
