Seeking geared unicycle prototype demonstrater/collaborator for startup company.

This reads like the reincarnation of dakoroman with some slight improvement in language skills. I don’t think the OP has any grasp of the engineering requirements or materials limitations for a project like this. Regardless of any claims that this is not somehow personal, the OP responds with accusations of personal attacks rather than with any discussion about technical details of the project.

We have all seen this before.
