>>1983641Well, in Sweden there's an actual monopoly by Monark-Screscent.
You can get "a" 16-20" folding bike off the shelf, may be a 1700 € Brompton, may be ~500 € anonymous brand or some mega hipster electric assist cough up 4000 € kind of deal. 24" with hinged frame is hardware store tier but those are hardly portable.
This is what I mentioned before, surely a common configuration Europe-wide? Sadly I have no Idea how the price would have compared to a 3 speed.
