Requiem

I'm 6'2" and measuring my bike frame it looks to be 51.5cm or so. I'm sure this is pretty small for someone my size, but I don't really have alot of money to throw down on a newer bike at the moment. I'm just trying to make do with what I have. As I said, the only time I really feel any discomfort is when I'm riding taller on roads. Trails are pretty decent as for as comfort goes tho.

I guess what I should be asking is... what's the most cost effective and simple option to go with...
