The funeral will be held Monday, December 28, 2009 at St. Justin Church in LEVALLOIS 14 H 30. LEVALLOIS Cemetery after the ceremonyErnest Csuka, as many of you know, was the last of the great French constructeurs. He took over from the legendary Alex Singer in 1964 and continued to build what many, myself included, felt were the finest bikes ever produced. Ernest started with Singer in 1944 and introduced numerous innovations over the years.
We assume that his son, Olivier, will continue production of Alex Singer bikes.
