The safety organisation VeiligheidNL estimates that 5,000 fatbike riders are treated in A&E [ i.e Accident & Emergency] departments each year, on the basis of a recent sample of hospitals. “And we also see that especially these young people aged from 12 to 15 have the most accidents,” said the spokesperson Tom de Beus.
Now Amsterdam’s head of transport, Melanie van der Horst, has said “unorthodox measures” are needed and has announced that she will ban these heavy electric bikes from city parks, starting in the Vondelpark. Like the city of Enschede, which is also drawing up a city centre ban, she is acting on a stream of requests “begging me to ban the fatbikes”.



There isn’t much to figure out. Treat them as what they are: Small motorcycles, and as a consequence, require a license, insurance, mandate helmets, ban them from roadways reserved for non-motorised traffic, and enforce minimal technical standards.
I disagree, I think they have other properties than small motorcycles. Motorcycles drive faster than 30-45 kph, are more expensive to buy and maintain, and they’re noisy, whereas electric bikes are noise-free.
Requiring an insurance and license makes them needlessly expensive - in China, neither is required, except for wearing a helmet. (on paper, they require license & insurance, but police doesn’t enforce this).
