Banshees are the best bikes i've ever riden. I ride mine in my field, on logging trails, Skitter Trails, woods (i blaze my own trails), and of course the dunes. If you're planning on slower, mud and water type trails, go with some kind of four stroke. I'm not saying that banshees suck in the mud, but you have to keep them fairly high revved and can't lug around in 3rd gear. As far as power goes, these things have the most (as far as i've found). They are great for dunes and trails alike. Go to Cycle Trader for good prices.
