FUBi Bike is one of the most compact folding bikes on the market. The frame itself folds down to fit into a tennis racket bag. The greatest part is that when the bike is unfolded, it looks like a normal bike and not a compact oddity with tiny wheels. It can be folded with the wheels connected or detached for an even smaller footprint. FUBi is also configurable with three different wheel sizes; the narrow road rim, the city/gravel rim, and the mountain rim. This allows the bike to function in a number of environments. FUBi comes in three sizes: 25″, 26″ and 28″. FUBi ships in May for £1,499, but you can order one through their Kickstarter campaign HERE for £989, shipping April 2014.
