From the early start Triumph gained popularity quick. They proved on many occasions that their machines could be ridden long distance reliably. In 1915 Triumph produces the 550 cc Model "H" Roadster. The bike was nicknamed "The Trusty Triumph" because 30,000 of them rolled off the assembly line to supply allied forces during world war 1. The bikes no longer had pedals and they were fitted with a kick start lever and solid footrests.
