I have been riding a Bikefriday with a 350 kit retrofitted and have been thinking about moving it to my Greenspeed Magnum tadpole trike. I would then get a bionx d500 to put on my old Surly Karate Monkey. I am 6'5" and around 240lbs and I am concerned about the difference in torque/power when climbing. Would the extra size in wheel size and power have about the same feel/effect as the smaller wheel with less power? If the trade off is not about equal, then I would be looking for a long distance touring bike solution that was integrated to the bike, like Kalkhoff. I would appreciate input on such bikes that are big enough for me and a load for touring with credit card (no tent or sleeping bag or cook ware). Btw, I love my Bikefriday with the bionx setup. I have put 2000 miles on it since august15, 2015.
