Maybe that’s true but the sense I got from the linked articles was just that they are cheap bikes sold at supermarkets. In that context, they are advocating that you should spend 250£ on a bike, with parent suggesting that these 70£ bikes be banned. Why should we ban shitty bikes that poor people can afford? Why should we ban “fake mountain bikes”? Certainly if they are actually dangerous, but there’s existing consumer law to handle that case. (Also, I laughed when the authors wondered “if it’s such a rare flaw why do we see it all the time?” Like you’re a bike repair shop, pal. Of course you see the ones that are busted. That doesn’t tell you much about the rate of failure.)
