I used to BMX when I was a teenager and since then I've been into fixed gear bikes. Recently I decided I wanted to do some trails and dirt jumps with an old friend and I've been looking into bikes and obviously because of my history with BMX I keep gravitating towards dirt jumpers. I have narrowed it down but the one nagging question is gears or not. If I go single gear will I have trouble doing trails on a mountain or in the backwoods? I definitely want to get a decent starter and it seems like the bikes with DJ 2 forks and decent cranks are mostly single gear. I was also thinking about building up a pimp trailking but that would definitely be single gear. I like the steel reserve Haro 1.3 but thats single as well. The Mongoose Ritual dirt seems decent but the parts aren't that great but it does have a good frame and gears. I'm definitely into tricking and jumps but I'm not going pro or doing any pro ****. If anyone can help I'd appreciate it.
