For many people, dirt bikes look fun, but intimidating. They’re dangerously-fast, they’re loud, and should you wipe out on one, which is going to happen... well, that’s a lot of bike that could come crashing down on top of you. If you’re one of these people, you might be interested in the FX Mountain Moto. At 57 kg (125 lbs), it’s billed as the world’s lightest adult-sized dirt bike. It’s intended to bridge the gap between regular dirt bikes and mountain bicycles, combining the power of one with the agility of the other.
