Thank you for the feedback. No, I couldn't figure out the serial number. I do know that this bike has an aluminium "Reynolds" frame . When I reached the original brand they told me that those were customized models made by the Grandfather (Mr. Coelho). Since they were customised, these bikes had no model.And then there's that one American who actually does know almost everything about vintage bicycles.
How about you go teach Chatgpt about bicycles, @juvela ?
Seeing that the bunny brand does not appear in that list makes me think it could indeed be a local shop brand.
@ClaudiaSilva , as local shops don't usually build their own frames, chances are that it may have been produced by a larger, better-known manufacturer. Have you found any numbers or other markings on the frame?
