After seeing both vids, I still kinda like the look/concept, but even i with my armchair engineering lack of qualifications can see the multitude of ramifications and complications it creates..
The size of the 'bump' in the rd that caused the 'noise/ skateboard wheel pin failure' in vid #1 was comically nominal - If i had been a) a backer, and b) received a bike, chances are it wouldn't have made it to the end of the rd on its initial run ( btw im 3rd house in..) .
Shame tho - I still Kinda like it
If any made it to the UK i bet they end up on the walls of hipster barbers..
