I bought a Giant Escape City today and I love it, but it feels so much smaller then my 26' Schwinn Admiral. On my Schwinn I always kept the seat way high so that I had a good leg extension and my knee was just slightly bent at the down turn. They sized me with a machine to get proper measurements. When I first got on my bike the saddle seemed too low and my legs were really bent but the guy said that that is where it should be. When I got home I raised the saddle anyways because I didn't feel like my legs should be that bent. My question is how bent should my legs be?
