Not that a banana seat is going to be comfortable as it looks like a PITA as it sits. But, lower it, adjust the handlebar to the rear where you can set back in the seat and, no doubt, balance/center that Kenda might help. [maybe]
What is it that makes it the most uncomfortable bike you have ridden? Sitting to far back, bars to high, to much stretched out, forward pedals? I'm just curious. I don't own a banana seat bike so you got me thinking of the ergonomics of them. Allways thought they look comfortable, was just not my thing.
I changed the seat and adjusted some stuff like the bars and wheel and sissy bar, and it rides ALOT better (my ass was just too boney for the solo polo) this bike is now for sale however because of my prewar obsession
I had a 26" Speedster built up as a big Stingray. My bony 45 year old butt can't take the banana seat.
Swapped the stock "S" seat on, and all was well.
Now I ride a 53 Panther with Stingray bars and original style seat.
Banana seats are good for ten year old butts.
I have considered trying out the one company who makes the thicker padded adult butt freindly banana seats, though. They even have slightly longer ones that look more proportional on a 26" bike.
I had one I couldn't get seated, so I took it to the local bike shop where they had a Park Tool PTS - 1 Tire Seater. The guy grabbed hold of the tire and yanked, and it popped into place. It took about two seconds, but he had probably had some practice.
