A few years ago, this weekend in 1965, I crashed one of these by running into the back of a parked van in nasty wet weather...
I was only a few yards from home, and my goggles were very misty from the rain, and I just didn't see the van until it was too late! I got chucked over the handlebars, and finished up on the other side of the road, very much unconscious, and as a chum who lived opposite exclaimed later, looked a bit 'deadish'!
In fact, it was only a spell of concussion, plus bashed up knees, which funnily enough only tore a tiny bit of trouser on one side, but it turned out that the kneecap had chipped, and a few stitches later in St Helen's Hospital in Hastings, I settled in for the statutory ten days recovery!
What was odd, was that with a chum we had been right across Belgium only a few weeks before, and the only mishap then, was going over a pothole near Brussels, and the handlebar cover shot up in the air, breaking the screw which held it all together!
The scooter was a write off, but dad persuaded the engineers at the farms where he worked to straighten it all up, and with a new frame (£5.0.0), I rebuilt the whole thing, and used it for ages! It used to go like the clappers, and was a great little scooter, but like all things, it had to go, and was last seen dumped in a hedge not far away...
