interesting-
I wonder if I can post pictures yet;
I think I've got a peach of a twenty, as it happens
(unless I'm in a complete fantasy world about what it is!)
In fact; perhaps I am- as my one doesn't fold! I was lead to believe at one point this might have been a 'Gemini 20'
It doesn't have these crazy tyres on any more; this is a legacy pic from the day I got it a couple of years ago...
