I'm into old bicycles and saw several bikes before, old bikes, with local city plates. I heard from owners that bicycles are registered before in city/municipal halls much like the tricycles we have now.

Im just wondering if any of you guys know if there are cities/towns that still do these? Maybe we just don't know.

My intent actually is to get my project bike a local plate. I'm building a touring mini velo and the plate completes the look of the project bike

Also if you know of custom plate maker who can do the size of motorcycle plates, that will be really helpful. Thanks!
