Amsterdam prepares to ‘ban the fatbikes’ amid rise in serious accidents
www.theguardian.com
Experts say souped-up e-bikes pose big risk for children aged from 12 to 15, who account for many A&E cases

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”.

    That was sadly exactly what I was expecting from the electric motorization of bicycles. It is a history that has repeated itself many times in the last 70 or 80 years since the first combustion engine mopeds.

    The fact is that the human-powered bike is at a sweet spot of efficiency and safety. Once you go faster, you need a helmet, a heavier frame, wider tyres, better brakes, wider lanes, protective clothing, protection against cold, a heavier motor for propelling all the extra weight, and so on. The energy input from you the human dwindles.

    It is not any more a bicycle.

      You need a helmet on purely muscle-powered bicycles, too. A helmet saved both mine and my father’s life in accidents that would not had happened were we not riding bikes that moment.
      A majority of bicycle accident fatalities could have been prevented with helmets.
      Wear helmets. There are cool models, too, don’t try that excuse.

        I lost a friend to head injury in a bike accident a month ago. (Hit by a car.)
        I don’t know what state I would be in now if I hadn’t been wearing a helmet the numerous times I’ve come off.
        Exposed rider of ANY vehicle using a road or a bike lane should wear a helmet. Like car seatbelts, this should be law.

        Oh man I got a concussion while wearing a bike helmet I probably would have died if I wasnt wearing it. And we were just kids makings jumps in the driveway…

        I vaguelly remember a study in Denmark (which has roughly 50/50 of people cycling with and without helmets) that showed that cyclists who wear helmets were more likely to have serious accidents than those who did not, though by a small percentage.

        There are several factors that are believed to be behind such an unexpected statistic:

        • Drivers actually act more dangerously around cyclists who seem better protected than around those who do not and the cyclists themselves are more reckless when they feel they’re better protected (the latter being a much broader and well known phenomenon)
        • The weight of the helmet, even though it’s quite low, will on a high speed collision pull the head more towards colliding with something than otherwise - in other words, if you fall the helmet actually unbalances your head and makes it more likely your head will hit the ground.
        • The human brain is much more resilient to linear shock than rotational shock - basically when something makes your head rotate the brain inside will also rotate though not instantly since it not part of the bone of your cranium, so it will instead get pulled to rotate and similarly when the head stops be pulled to stop rotating, all of which can cause tearing which can kill a person. Cycling helmets tend to make the head rotate on a collision.
        • Cycling helmets are only rated to protect from collisions up to (if I remember it correctly) 15km/h
        • Cycling helmets do not protect anything else than the head (which links back to the first point)

        Anyways, the point being that at the kind of speed and the environment that people cycle in when just commuting in a city, bicyle helmets can actually make it slightly more dangerous.

        Mind you, this doesn’t at all mean that in different situations - such as mountain biking or speed cycling - helmets aren’t a must.

        In places like The Netherlands pretty much nobody uses a helmet when just cycling in the city.
