Strutt Worksong folding bike
Invented by Mike Strutt, the Strutt Worksong folding bicycle is relatively rare since they were all handmade in England in small batches. The earliest model, the Mk. 1, had a bit more elaborate frame with more supporting tubes. While the bike was a full-size folder, it did use smaller 24" wheels.
