To be honest, I wasn't sure about the whole gyros thing and thought that it was unneeded complexity, until I realised they were also using them for regenerative braking/power. Then I went ooooo...
If they are really smart with this, and if the gyros are up to the task, they could use them for ultra fast charging as well.
The gyroscope keeps the vehicle from falling over when stopped. Even without regenerative braking, thats pretty necessary complexity when you can't stick your foot out to add a third point of contact.
I'm thinking about some metal tubing welded a bit like a splayed out capital 'H', that is the width of the bike and hinged along the middle bar of the 'H', which you can push forward with your foot and has a spring on it. Attach rubber ends if you want to make it fancy.
