sentences:  Although road and track versions of the recumbents were built in small numbers between 1933 and 1945, as well as, in 1935, a simplified version called the "Velorizontal", and record-breaking continued in non-UCI categories, the Recumbent impetus was lost after the war, the last Mochet model being the 1940 version of the "Vélorizontal".Around 35 Mochet recumbents survive (2011) in museums and private collections.Re-discovery of the Mochet concept in California in the late 1970s led to the subsequent development of recumbent cycles that took place in the US in the 1980s.
