Mike from Norfolk in the UK here.
I have just picked up my first folding bike secondhand and I love it - I have permanent smile when riding it (maybe because it is so small and I'm over 6ft!!) I have had many comments as people love how compact it is.
It's a Ridgeback Compact (I think from about 2004)
Does anyone else have any more info? It has 14" wheels and an aluminium frame.
