So here's the thing. The last bike I bought, I definitely needed and wanted. Well, I didn't actually need it in the true sense of the word, as by that time I already owned four other bikes, but I did 'need' it to fill a gap in my stable.
It occurred to me cycling back from a childcare errand this evening that I don't think I really need any more bikes. There are a couple that I sort of want (a recumbent trike and a Tern GSD, for example), but I don't need them and I'm not going to try very hard to persuade Mrs G to loosen the domestic purse strings.
I've got a folding bike for the train, a sensible commuting bike with disc brakes and hub gears and a dynamo*,a cheapish road bike that lives mainly on the turbo trainer but can be an emergency commuter, an Elephant Bike for carrying stuff and a fancy bike that gets ridden occasionally and cleaned meticulously.
Is it there a value for n where the number of bikes one wants tends to n rather than n+1? When will you run out of the need to buy more bikes?
(*actually all five of my bikes have dynamos on them)
