Bikes and moving walk ways.

I was rocking the baby off to sleep and had an odd thought.

People have been thinking about  moving walk ways since the paris exhibition in 1898? The problem is getting people on and off. If you keep a constant speed then the speed you run at is walking pace, any faster and you have to run to get on. Other systems change speed so you get faster in the middle but then you get people getting closer to each other when the system slows down and then people trip over each other at the end. 

I realised that with a bike and a very narrow ( 30cm, 3000mm, 1 ft) wide moving walk way you could run bikes but not people. Unlike people if the bike is running slower then the moving walk way then the wheels would run backwards slightly until you where accelerated to the running speed. 

Finally and most importantly you can use momentum on a bike   

If your going along at say 30mph on a bike then run on to static ground (say the belt ends) then the bike's momentum will continue on.This is something pedestrians don't have. This gives two advantages firstly you can just end your moving walkway at high speed and not really worry about people bunching up - the momentum will carry them away just give space to widen out the path.

Secondly if you have 10m segments then if a segment stops ( needs repair) then the cyclist will just continue with momentum decaying until the next segment starts. 

So with this you can run a system with stations at intervals. Where cyclists just run onto a side path then pull on to an open area to peel off. No changes of speed should make the moving walkway simpler. 

I have seen short moving walkways for cyclists in Holland to go up small hills. I'm thinking here of something much longer ( 1-10miles/Km) and potentially much faster. Going up hill is really good, but the ability to make a long high speed 'super cycleway' backbone. A cycle equivalent of a motorway is what intrigues me. 

I wonder how much energy it takes to run a moving walkway? Is this better and more safe than being pulled by a ski-lift like rope? We don't have assistants on escalators/moving walkways could this be extended to cyclists? The trump system appears to need no attendants this is also in the ground.
