What happens when the electric motor on your coffee mill fails and you have several large orders to fill? Well if you are like Denver's Early Coffee Co. your Excelsior delivery motorcycle could make a fantastic replacement. In the winter of 1909 a boiler explosion at the Denver Gas & Electric Co. left the city without electricity, but the uncaffeinated hoards still demanded their morning cups filled. The single cylinder Excelsior Auto-Cycle, which ran continuously for 4 hour sessions was such a successful substitution that other local companies soon brought in their own delivery bikes to keep up with production.
