| Videos+: Technologies and inspiration in action | Guy builds omni-directional ball-wheeled bike
Do you remember last September when we featured YouTube maker James Bruton and his funky, self-built Mecanum wheel screw bike? Well, Bruton has been busy; this time around he has designed and created an equally wacky omni-directional ball-wheeled bike. He says he used 3D printing for much of the build and five ODrive brushless motors to keep the balls spinning. Really fun to see him work it all out. Riding the bike brings a whole new meaning to drifting. [Credit: Screenshot courtesy of James Bruton YouTube channel]
