Old bike from Jan Breur. Jan Breur (Schiedam, 23 dec september 1951-Vlaardingen, 22 november 2010) was a Dutch road and track cyclist, who was a pro between 1974 and 1980. He was a specialist in the “stayer” discipline and he became third at the Dutch championship twice and once on the World Championship. That was in 1975 behind the German Dieter Kemper and the Dutchman Cees Stam. Teun Visser was a bicycle maker whose shop was located on the Hofdijk in Rotterdam the Netherlands. He later moved to oostplein 49, also in Rotterdam. Before he began his shop he was a mechanic at the legendary Televizier cycling team by Kees Pellenaars. Teun Visser built his frames not by his own but allegedly by White Ko. Most enigmatic Dutch frame builder Witte Ko, he seems to have made allot of fantastic frames that others sold under its own name. Via an article we found out that he is name is actually Jacobus de Jong from the infamous Jordaan area in Amsterdam the Netherlands. Like great brand from the Jordaan in that time is RIH Amsterdam. Which now moved on in the north-side of Amsterdam. A well known rider who rode with Teun Visser was rotterdammer Willem (Wim) Koopman. He was in the late 1960s (tandem) one of the best riders in that discipline. The shop is closed in these days and also there is not much to be founf about Teun Visser.
