Say hello to the SteamRoller Riding Contraption, one of the strangest pedal-powered vehicles you're likely to see this week. Essentially, it's a portable porch swing stuck between two giant wheels. As you pedal with a friend, you swing back and forth. It looks relaxing while also kind of terrifying, as I have no idea how you would steer this thing. But still, if given the opportunity I would ride this thing all over town.
