My first post here and currently not a CB owner. I have owned 7 different recumbents including one FWD which was a Reynolds Zbone which was not an MBB. Haven't had a recumbent for a few years now. Looking at the QX100 or a used Quest. On my previous bikes I used seat back bags. The last bag was for the Lightning P38 but I don't have that bag or any seat bag anymore. I generally like to use the bag for storage and especially for carrying a water bladder inside. Any suggestions for bags would be appreciated. Another question is related to seat comfort in general. The seats I liked the best were the Bacchetta Euromesh and the carbon fiber seat that came on the Zbone.
