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”.

    Yes, right.

    But: A bike helmet won’t help you much if you have a collision at 50 km/h. If you go at moped / light motorcycle speed, you need a motorcycle helmet, too.

      Yeah, obviously you need different helmets for different speeds. But the comment I responded to was worded like you wouldn’t need a helmet on bicycles at all.

        In principle, this is correct. But the need for a helmet increases massively with speed.

        Consider the end speed of free fall when falling a certain height - or the inverse, height in meters versus speed in kilometer per hour. It is:

        10 km/h   ..... 0.39 meter
        20 km/h   ..... 1.57 meter
        30 km/h   ..... 3.54 meter
        40 km/h   ..... 6.29 meter
        50 km/h   ..... 9.83 meter
        

        Would you jump from ten meters height into a concrete surface? Few people would, because it is almost certain that you die. But the frame pillar of a car is equally hard as such a surface.

        Another data point: In the center of Copenhagen, not so many people use a helmet, but the speed is typically between 10 and 15 km/h - so many bikes there ! - and the number of serious accidents is very low. The contrary is the case for Germany.

        And just to make a point: Using a helmet is always safer.

          So? Nobody is arguing about this but you. Again, my point is not about speeds or certain types of helmets. I just said you should wear a helmrt on bikes FFS!
