1999 - 2005 Hungarian Solex S 3800 USA

 

1999-2005 Hungarian Solex S 3800

 

1999-2005 Hungarian Solex S 3800 General Information:

 

 The original Velosolex company was purchased in 1974 by Renault, then one month later by Motobecane which became MBK, and then closed up in November of 1988. The machinery used to manufacture the S 3800 model was eventually purchased in 1993 by Gathy Kiss and Georges Safar and relocated to Hungary, where S 3800s were manufactured until 2005 using leftover French parts and new parts made in Hungary at the Impex and Cyklopress factories. By 2005, several of the larger chains of machinery had become worn and were scrapped.

 Today, about 80% of the machinery is still in operation manufacturing parts in Hungary, but no complete S 3800s have been made since 2005-06.

 Hungarian Solex S 3800s were sold in the USA by VeloCruz in Utah from 1999 until 2005. They were available in both Standard and Deluxe versions, the Deluxe version having stainless steel fenders.
