as there was nothing to compete in the UK market at the time.

Dr Ehrlich worked throughout his life to improve engine performance. In 1948 he built a three-cylinder motorcycle engine that was banned from racing circuits as "too powerful".

Ehrlich's experience with early two-stroke designs led to work on the 'Environmental Engine' that had variable compression and variable capacity to improve emission and fuel consumption.
