I remember those rolling on the front wheel. In fact an older friend had one, you pulled a lever to lift the motor off the wheel. I also remember it being very problematic if your front tire went flat!I recall was a BSA Cyclemaster too and a few other manufactures had similar ideas. I do recall one which sat on a carrier over the wheel and had a pulley rubbing on the tyre
Good looking bike!

Wasn't there a French engine mounted over the front wheel called a Solex?The BSA suits dithered, as suits are prone to do, but late in 1951 decided to get into the motorized bicycle business, telling the boys at the New Hudson factory on Coventry Road in Birmingham to get cracking. In May of 1953 the company presented the BSA Winged Wheel to the public. It was a nifty little device, really, even if a bit rudimentary, a tiny engine with clutch and gears that fit into the middle of a bicycle wheel, and selling for a quarter the price of the Bantam; all you needed was your own bicycle. Apparently, rear bicycle wheels were all pretty much the same, and this Winged Wheel could be fit onto any number of bicycles
