This contraption, if you can make it out, is the brainchild of a young lad in West Lothian whose father is a customer of mine. The bit on the far right with the vertical pipe welded on is slipped over the seat post of a bike, the throttle is somehow fixed to the bike's handlebars and the engine and chain driven wheel stick out the back! The engine is then fired up and Bobs your uncle and off you go with the motorised wheel pushing you along! Heaven only knows how you steer the thing but he assures me he's had over 40mph out of it. I can only add, "rather him than me"!
