Hill crushing beast!
I love this bike. I've ridden it a fair bit and though some gnarly trails and up some tough ascents. It just flies. Top speed flat and level of around 35, I'm 6'3" and 200lbs. If you're tall, buy a large.
I bought this for my wife, who is 5'8" and it's a great fit. She has a dehabilitating disease that saps her stamina. This bike has been a great equalizer. She can ride at my speed and climb up hills that she couldn't walk up.
It rides like a normal bike just a little heavy.
