The Dutch government plans to make helmets mandatory for minors riding electric bikes, following increasing complaints about disturbances linked to so-called “fatbike terror” caused by groups of youths.
The decision, announced on Thursday by outgoing Infrastructure Minister Robert Tieman, is part of a proposal he hopes to pass through parliament by the end of 2026.
Fatbikes, a type of high-powered electric bicycle with the appearance of a moped, have become notorious for being illegally modified to exceed their 25 km/hr speed limit, sometimes reaching speeds over 40 km/hr. These changes have led to dangerous situations and even fatal accidents.
The measure comes as the Netherlands grapples with political turmoil. After the departure of key political parties, Prime Minister Dick Schoof's administration now holds only 32 out of 150 seats in the Dutch House of Representatives. Despite its caretaker status, the government has pushed forward with new policies, such as the crackdown on fatbike-related issues.
Dutch media have extensively reported on what they describe as “fatbike terror.” Groups of young people, often riding illegally tuned bikes, have been accused of harassing local residents, prompting widespread concern.
The rising popularity of fatbikes has come with significant safety risks. According to the safety organisation VeiligheidNL, 96 fatbike riders visited emergency departments within just one week last year due to accidents. Nearly half of those injured were between the ages of 12 and 15. By comparison, 480 people were hospitalised in the same period because of accidents on other types of electric bicycles. Most victims involved in these incidents were not wearing helmets.
By introducing the helmet mandate for minors, Dutch lawmakers hope to reduce injuries and fatalities associated with these bikes. The decision has been met with some relief by emergency responders, who have long voiced concerns over the safety hazards posed by the growing use—and misuse—of fatbikes.
