I have made the decision to acquire a mountain bike. Looking for advice.

My goals are to get something that will work for both riding through state / national park and forest trails, as well as occasional trips to a local ski resort that operates downhill bike trails in the summer, using the ski lifts. I’m looking to do this for the leg workout, general having fun, and picking up babes.

Budget is up $2,500 for everything, including safety equipment. I already have gym shorts and flip flops that I use for my motorcycle, so won’t need those. I would also like to order online, from anywhere but REI.

Any suggestions?
