I had a numb left buttock & lower back for 6 months after LEL17 (on recumbent) and a bit of tingling for a few days after PBP15, so nothing’s perfect. Granted I’d have paid good money for a numb backside after PBP11 (on a steel road bike) but in all fairness it’s the only long ride I’ve had any saddle soreness on. I am a bit fat too.
I always had slightly buzzy hands when I rode purely “normal” bikes. But now I mix it roughly 50/50 I have no problems.
I struggle more than a few feet no handed but both my recumbents (Metabike & HPV Spirit) handle as well one handed as two handed. I think LMT rides a slightly less conventional recumbent (front wheel drive with a moving bottom bracket?), steering, no handed, with your feet is not something most two wheelers can do (I could do it on my, now dead, trike).
Truth be told, if I didn’t have a knackered left shoulder, I would probably ditch the Metabike. It’s not quite as much fun, unless it’s going downhill. I’d love a new trike though.
