Meet the Sada Bike: an elegant bike that folds down to the size of an umbrella. The bicycle still has standard dimensions but can be moved around easily. The wheels have no spokes while the packaging container can be used as a backpack. The bicycle can be folded quickly.
The bike has a system that anchors the wheels using a small frame and a quick clamping device. You can’t buy the Sada bike yet, but it does show promise.
