Ok I am 5'11'' and about 240lbs. I hate mountain bikes and would like to stay away from those if I can. So I would like some ideas that would fit my need. Such as riding around on street/dirt and taking it off some ramps/jumps every now and then. A price range of max $300.00 would be nice or even some suggestion of material I should look for and size I should look for.

Thanks for any help.
