The quadem thread and "outer disc brake on a delta quad" thread now lack photos due to photoimage and the inability to change the links
it was running on 20" wheels basically as it was a converted streetfox with a long rear end. The engines combined age was about 130yrs old which didnt help much .
it was a great laugh especially at xmas dressed as 2 santas .but I would not and never did use it for more than a few miles about 10 mles was the limit , we use the e-trikes all the time now as they work for us
