Motorized Bicycle

The historic photos represented here showcase the 1904 Marsh motorized bicycle. Marsh was one of the early motorcycle manufacturers on the east coast, starting in 1899. The business was located in Brockton, Massachusetts, where the Marsh brothers built motorized bicycles and manufactured their own engines. In the photo you can see that there are a few added embellishment to the motorized bicycle including a handle bar mounted horn and what appears to be a tire pump located on the frame.

The motorized bicycle had a single cylinder with an intake valve which opened by suction created when the piston was on its downward stroke (called an "atmospheric intake valve") and a mechanically actuated side exhaust valve. The spark plug was fired by a "total loss" ignition system. This meant that there was no generator to recharge the battery. It had to be recharged by an external source. The original production engines produced less than two horsepower, but later models offered six horsepower which powered the cycle to nearly 60 miles per hour. The overall dry weight of the cycle was about 150 pounds.

By 1905, the Marsh brothers had teamed up with Charles Metz and company changed it name to Marsh & Metz. Even though it helped to pioneer the 90-degree V-twin engine, by 1913 the company closed its doors."
