Via @dezainnet, video of designer Ron Arad’s Two Nuns bicycle with wheels made of sprung steel loops instead of spokes and rims (that’s Arad on the bike).

“To account for the added flexibility in the materials, Arad’s sprung wheels of steel are in fact a little bit larger than the average bike wheel, says Marcus Hearst [he’s the other rider in the video], director of the design department at Arad’s studio. But it’s this yield that gives the wheels a slight cushion and makes the wheels work in a practical way.” More at Co. Design.
