When did mountain biking get so uptight? As we see it, fun is a right, not a privilege. And no matter where or when you're riding, it should always be at the heart of each pedal stroke. So whether you're on singletrack, sand, or snow, your bike should perform with this in mind. Naturally, this is where our Fatboy mountain bike comes in. Itâs built for good times, and most likely, itâs the one bike missing in your quiver. But with tire clearance for up to five inches, a lightweight M4 aluminium frame, snappy handling, and rack mounts that make it adventure-ready, the real question is, "what's taken you so long?"
