This bike is built to be beaten on. It takes whatever you give it. I am 6'5" 250 and went for the XL. I am so happy, I went for the disk edition, it gives you that extra stopping power.
When I am out riding along the lake (Chicago) and the path it to crowded (Irving park to Navy Pier), I have no problem jumping curbs, riding on the grass, dirt mound hopping and all out having a good time. While the guys with the skinny tires are stopping every 5 seconds, I am tearing it up!
You will be happy you got it.
