I'm just under 6-0 and I test drove a Large Bad Boy Ultimate this year before purchasing the F3 for the same money and at the same size. I have a 32 inseam. I would think at your height, an XL would be a better fit. JMHO I found the BBU to have a very stiff ride even with the Head Tube Shock. Look closely at the frame spacing front and rear and you will see that you cannot add a very wide tire at least not in the 700c series. I found for the same money the F3 had better specs and for my money and application...a better ride.
