Now this is downright weird. The SidewaysBike's rider sits either sidesaddle or facing toward the front, manipulating controllers that steer the front and back wheels independently. It looks a lot more maneuverable than a conventional bicycle, but we're not sure if it's stable enough to ride alongside the road in traffic.
This strange bike was invented by Michael Killian, who also created the Sideways Scooter. There's no indication whether either will be commercially available anytime soon.
