6. Humber – 1902


With a strong reputation for manufacturing bicycles the Humber company broke into the motorcycle manufacturing business following a brief foray into powered tricycles. Using successfully proven patents from the tricycles, Humbers entered the market using the engine as a stressed member where the front downtube normally would reside. This design circumvented the Werner’s patent of engine placement and is one of, if not the first, motorcycle to use the engine as a stressed member of the frame.
