Great bike!  Now substitute an inflatable clear plastic pod for the wind screen for crash and weather protection.

And two rear wheels for most commuters, but that would take more train space too.  For the adventurous this is perfect.

Would mass production in china bring the price down to under 1000 bucks?

And arm pedaling power would be nice as well.  Compensating for the lower power of 'bent design.  Normal biking uses the whole body when you stand up and pedal.

Now if only it could be made safe and affordable.
