That, in turn, led him on to designing a new frame that was one of the best made in the business. It could be fitted with one of several engines, often modified, such as AMC, BSA or Triumph.

In 1970 and 1971, a trio of these very reputable motorcycles, 504cc Cheney Triumphs, ran as the British team in the ISDT (International Six Days Trial). Replicas were built, but production was short-lived due to a shortage of engines.
A take-over by Ken Heanes resulted in the Heanes BSA Thumper, and Eric Cheney moved on to making frame kits for Japanese and European engine units.
