Have any of you guys who are way above the 200 lbs threshold (say 300 + lbs) figured out how to get truly comfortable on a bike to the point where you can ride for hours? I weigh 400 lbs and I can't image ever being comfortable given the range of saddles, pedals and grips. I can only manage 2-3 miles before I'm in so much pain that I have to stop riding. I've tried different saddles, different grips and about a thousand different set-ups for fit, yet I still can't find a point where I could sit on a bike for even 10 miles, much less 20-50 miles.
The main culprits are severe pain in my feet and burning in my perineum/genital area. I've tried different shoes (always flat pedals) and a split saddle, but neither helped.
I'd love to hear some people here's experiences in getting comfortable on a bike.
