I just got my very first real bike and love it. I was only able to ride it for about 45-60 min before it got dark but I loved it. Man am I out of shape! My legs aren't really that tired but my I kinda took it a little to hard at first and hit my ass a few good times when I was going over a few mounts of dirt around my place . Hopefully my butt gets used to it.
Anyways it is a Gary Fisher Wahoo. I love it so far. Going riding with a friend of mine for 3 hours or so tomorrow .
