The HulaBike is another hand built creation from the Bicycle Forest. Instead of a conventional drivetrain, the HulaBike uses an eccentrically laced rear wheel. Because the hub is offset from the centre of the rim, the bike can be propelled by hopping up and down with the right rhythm. You may not get far on the HulaBike, but you'll have fun trying. For a video of the HulaBike in action, check out the bottom of this page.
