I'm not so sure Emiel. It's hard to tell from such little pictures but the basic principle looks the same and he's also inspired by Alan Maurer's trike. That one makes what I'd see as an error in placing the main beam above the crossbeam. If the main beam goes below then you get the centre of gravity lower in relation to the central pivot which equals less effort to get upright as he found. Again, with the tiny pictures, I can't see the crossbeam bearings very well but it looks like he's using acetal which is not going to help matters in getting upright either. This thing really needs proper bearings IMO so all your effort goes where you want it. Steering input can help in getting it back upright and I suspect acetal bearings are going to make that harder. Whilst one handlebar is enough to apply steering it's very limiting in leaning and un-leaning, having two for lift up / push down is absolutely vital IMO. I suspect he was always intending to add the other later in the build but we never got to see that. Lastly he's copied Alan's minor "design flaw" and has to pull the handlebar(s) back to resist braking or would do if he ever got it finished. It seems much better to push to resist seeing as you're sliding that way anyway. That was a great find Paul.
