I've lashed together a fixie and enjoy it. Not something I'll ride all the time but I think I like it enough to have a 'proper' one.
I'll be getting it through our company bike to work scheme. I've not used it before but think it had to be through Halfords but not limited to their retail range. Also there's a limit of £700 which I don't think can be topped up.
So what's out there.
