The Evel Knievel Canyon Sky Cycle was issued in 1974 and continued in production untill 1977.
There were a couple variations made, one had a blue paint on part of the body and was later replaced with blue stickers. The rubber bumper on the front came in white on early issues and black on later issues. White is very rare.This toy was and still is a very popular product. Sets with the box are valued between $300-$500 in good to excellent condition.
There was also a version issued in Germany.
