When a bike this fun comes along, you jump on it. Trek's Marlin 6 makes entry level fast and fun with a playful aluminum frame and size-appropriate wheels. Up front, the suspension fork gives you 100mm of travel, it laughs at trail obstacles and keeps you out of trouble. Then, add the 24-speed Shimano drivetrain, a host of reliable Bontrager parts and powerful Tektro hydraulic disc brakes and you're in for years of riding. You may want to call in sick tomorrow, the trail is calling.
