Hi Catrin

Sorry to hear of your dilemma.

If you've got a bit of time on your hands at some point, my friend Helen's blog may be of interest. Due to a problem with one arm so that she can't put weight on it, she cycles (extensively!) on a series of recumbent trike. She doesn't talk much about her health problem on her blog, but you can get a feel for all the types of riding she does, here in the UK and in Germany, with the trikes.

All the best
