Kosynier is a family operation founded by brothers Marcin and Michael
Bielawski. We grew up in the forge, which has been in the family for over
100 years. Since childhood, we've been interested in historical motorcycles
and cars. We dream of producing Kosynier retro electric vehicles.
Bicycles are just the beginning.
