Hermitt,

Your employer should be doing their bit for the environment! Shame on them!

By "flexy" I meant that the handlebars didn't feel very solid when lightly pulling on them and when cornering I could feel the frame flex slightly, but that could be down to my weight (around 105kg). The more expensive Dahons are supposedly more rigid (better quality components I guess), particularly the Mu P8. I won't know for sure until I try one.

The Mu XL mentioned by someone else in this thread looks good, though I'm not a great fan of hub gears since I crashed a bike when the hub gears failed/slipped.

Try the Speed D7 for yourself at a dealer - if they're not willing to let you have a test-ride then give them a miss. You should be able to try out a bike for a few hours on varied roads, taking in a few upward hills.
