Matt52 - Thanks again for the in-depth info. The point about the cassette is a good one and I will certainly be wary of it. The bike is looking a strong contended.

Fear&Trembling - The Jetstream XP is available in the UK and (just) within budget. I am considering it as the suspension will make one bone-shaking route to the station a comfortable and regular option. How much larger a folded package is it? Ideally I'd prefer a hub gearing - cleanliness and maintenance only.

Adlopa - Not for the tube but okay for the train? The Jetstream P8 is also high on the list and yes, the company does support Cycle Scheme

Thanks folks - test rides this weekend.
