I don't know what make my three-wheeler was, then three Raleighs (getting bigger in size each time). Then I acquired my brother's Puch.
Then a long gap and I started again with an Apollo, then my Revolution (still have the frame), my Brompton for commuting (still have), a Dawes frame built up with help from the cycling charity I volunteered with (still have), Elephant bike (given away) and now the Specialized e-bike.
