Why balance side to side when you can work the forward-back?

In an effort to improve the flexibility of cycling on a regular bike, Michael Killian has invented a bicycle with a distinct twist, quite literally. The sideways bike allows the cyclist to travel sideways rather than straightforward with a more flexible and dynamic approach. All that is required by the cyclist is to convert the traditional left to right balance, to a more complicated front to back balance. All well in theory, but this change is more difficult to adapt to than one would think.
