Get a powered micro-lite or a small plane. You've had enough bikes. I bet it would be impossible to get licence and registration though.
I was at the local grass airport and peered into a hanger doorway. There was a perfect old fashioned prop-powered small fighter, dark green with the red chinese star on it. The pilot said it was chinese made, very sound, very efficient and very cheap. I always regret I didn't look further into it. Maybe after all your experience in cheap china bikes you could lead the way in this for us ...? It was a Nanchang CJ6As just in case you take me seriously and decide to get one.
