Wiki:

"Fred Van Buren toured the world as a performer with his magic & illusion shows, performing with his wife Connie Greta as the magic illusion act Van Buren & Greta. A British born magician, Illusionist & showman who is also well known as a builder & magical inventor.

Possibly his most famous illusion in this genre is his fantastic vanish of a motorcycle and rider which has since been presented for the amazements of audiences all over the world. This idea came to Fred in 1976 during a summer season with Windsor Davies & Don Estelle at the Pavilion Theatre in Felixstowe.

now you see it...

The Magic Circle heard about the illusion and even before it was finished booked Fred to perform in their 1976 Christmas Show at the Collegiate Theatre in London.

The first televised performance of this new unique illusion was in a Magic Circle show at Caesar’s Palace Luton, in January 1977, a performance that created newspaper headlines. To lay people and magician alike the illusion is a baffling impossibility."
