Before the Brompton evangelists pile in, I would say that the points that the writer brings up are valid, but then he knew about them before he bought the bike didn't he? The Brompton is a pretty unique contraption, the point of its existence is the ability to fold small enough to fit on a bus or train with strict limits as luggage, yet give a tolerable riding experience. I find the ride perfectly fine, but I've had small wheelers before. As such, the vast majority of owners are not necessarily dyed in the wool cyclists. We might scoff at his inability to fix a puncture, or to realise that gearing can be changed, or even that Brompton offer variations in gear ratios off the shelf. As with cars, you could buy a less nickable folder. Folding bikes seem to be less interesting to thieves, unless they have "Brompton" written on them. Even 20" folders have a variation in ride quality between brands. I was lucky in my last folder, the Viking Safari, that it rode surprisingly well for a cheap bike, and I've had other folders that didn't ride so well. The price for that peace of mind is that it doesn't fold or carry so well, so if you get into conflict getting a Brompton into a cafe or shop, good luck with the alternative. Even the Brompton is a hefty lump to carry about. If you're not an average size, getting something that folds that is strong enough if you are extra large, or that is light enough to carry if you're small, poses extra problems. If you live somewhere that has a transport service with a more relaxed view on folding bikes eg anything with 20" wheels or less is OK, you can get by with an alternative to a Brompton. If you just need a bike that you can get into a car, there is loads of choice. Often though, finding a folder that suits your needs is the luck of the draw. The Brompton is the nuclear option if you need certainty that you will be able to get it on public transport with no quibbles. And despite what the writer of the article says, it's perfectly rideable just as a bike if you go somewhere that doesn't need you to fold it, even though I have other bikes better suited to particular purposes.
