Designer Paul Kweton has built the “Ring-O-Star” bicycle cup holder for those cyclists too antsy to actually sit at the coffee shop and drink their orange-mocha-frappachino. It uses a silicone ring and attaches to the end of your handlebar with an expanding bolt.
That road bar one looks like a knee-bang accident just waiting to happen, but the riser bar addition could provide a nice hot, messy treat for any motorist that tries to buzz by too closely. Even better, you could attach it to the “Arm Against Harm.” It seems Wired, Gizmodo and DesignBoom all think this is a really bad idea…and we concur. I doubt it’ll ever show up in your local bike shop.
