What a fantastic post, and more than expert advice, exactly what I was looking for, so thank you OP for posting it!
I had a nasty accident four years ago, and have been left with arthritis in both feet and a bad shoulder.
Needless to say, since then, riding (and losing weight) has helped, however I suffer with my shoulder on long rides, and my feet really suffer in bad weather (I ride all year around).
I thought I'd have a gander in here, and I'm glad I did, as I've been considering a 'bent for a while.
The advice about storage was the one I was considering myself, and I'm glad it's been put bluntly. As I've not long moved back home, and storage is limited, we don't have a garage or anything, and with my DF I can leave it easily in one room, walk it through the house before/after rides and it's all sorted, whereas the 'bent, I wouldn't be able to do it, especially as we have steps leading up to the front door.
Shame really, but will be looking out to try a 'bent at some point. One can only dream I get a garage with my next house.
