I have been wanting to do this type of bike since i was a kid...never realized there was so many people into it. My problem..im a big guy 6foot1 and 300lbs. Will a road bike hold me or should i just try to do a mtb? Or should i just give up on the idea. I have a new trek mtb but i want to keep it geared, but would love a single speed freewheel bike for the smooth bike paths i ride. I dont take my mtb off the smallest gears front and back most of the time anyway. Shoot me straight i know im not small, but i would love to have one and dont really want to wait untill i lose 60-70lbs(my goal weight) The asap part is i can get a nishiki for a good price. Thanks in advance.
