People telling you 56 is too small are correct. I'm 5'11" with a 32" inseam and I ride 56-58 cm bikes. I have one 18" bike that feels like a 57 cm bike. At 6'2" I'd think you'd be 2 sizes larger than me, 58-60 cm on the low end. I would advise AGAINST the 56 cm JTS even though I've had a prior version of the bike and did enjoy it.
