I have a design for a gravity bike I would like to build as an experiment, I would like to ask some questions about the turning abilities of fixed wheels with no pivotal steering.

Firstly, I know that any kind of slow manoeuvrability would be highly compromised by having no steering available other than the steering gained from leaning the bike to one side.

I'm wondering what kind of problems I may face in the finished article with no means of steering?

I intend to work out the possible turning circle of the bike once I've calculated wheel/ frame geometry but would very much appreciate an outside view of the concept.

If anyone knows of a device where this kind of set up is employed please do let me know!

Thanks in advance.
