I enjoy all types of biking, and I enjoy building, maintaining and fixing bikes.
Most of my experience biking is in the world of mountain biking, specifically trail riding but I also love downhill, enduro, and xc mountain biking. I have a little bit of experience rode biking from several years ago, but I never owned a road bike until a few months ago. It just goes to show you don't have to buy into the product to participate in the activity ;)
I enjoy BMX but I have shifted my focus away from that and towards mountain biking. But you can still catch me on a 1993 Dyno 10 feet in the air every once in a while.
