I, personally, also found out that pedal forward bikes absolutely KILL my arthritic knees. My Puma Nevis made me have to move the seat more forward than I thought I would have needed to, as it's somewhat pedal forward. It totally KILLED my knees. I still have it, as it's always been one of my all-time favs. I need a new shifter, and she'll be back on the road again.
Show me your cruiser.
