it's a Huffy men's bike, 26'' wheels. It seems pretty sturdy. (if it isn't it WAS only $10 at Good Will and has about $70 of new brakes etc on it... My seat's a nice narrow one with a cut-out that suits my girlie parts pretty well... I was thinking all I'd really have to do is lower the seat (the handle bars are as low as they go) before trying to do the hoppy stuff. I'm basically just working on getting over roots and rocks in the trail, maybe some minor curb-hopping, too... not much of the WILD stuff I saw on that site you suggested, though those video clips are really awesome =) Thanks for all your help =)
