Roy Haynes was the interesting bloke behind ElecTraction, He designed a range of motors including the Cortina Mk2.
Whilst ElecTraction closed its doors after only a few years, he did manage to build and sell a few of the ElecTraction Rickshaws. There was one for sale on Facebook Marketplace only last year, condition was rather rough however.
