Love Quicklys. Was given one years back that had been sawn in half. The owner intended to make a folding bike but got no further than the cutting up bit. Sorted it, had it sprayed in the maintenance depot where I worked. Bought the odd spare from a bloke who advertised in 'Motorcycle Sport' at the time.
Marvellous little jigger that came into its own during a series of railway strikes. The roads were hopelessly clogged but there was always room for the Quickly to squeze through. My commute time wasn't affected at all.
Finally sold it to finance my first decent lathe. Sold it to an Irishman who was delighted to get it. It was a sentimental purchase as a Quickly was his first bike. I tried to apologise about the rather pathetic brakes but he just beamed in delight and exclaimed "Thats roight, thats roight. (Irish accent) They were so awful on mine I planted it in the back of a Belfast bus!" It was the first (only) time I've ever found bad brakes to be a major selling point.
Yes, I do like Quicklys.
