Hi I am thinking about getting a Trek Bruiser 2. i am 5 foot 5" and about 130lbs. What size frame should I get. I was also wondering if it could handle our local freeride park. There are some ladders and drops and stuff and I want to go there but I want to make sure my bike can handle it. Here's the site for it. http://www.nemtb.com/MTBPark.html
