Westcoaster Mailster

The Westcoaster Mailster was a small three-wheeled vehicle used for mail delivery by the United States Post Office Department during the 1950s and 60s.

They could haul 500 pounds of mail, including large parcels, versus the 35-pound limit of a foot carrier, and once represented one-third of the delivery vehicles used by the Post Office.

Because of the population boom after World War II, the postal service needed a more efficient way to deliver mail, so in 1950 the city of Miami started to test three-wheeled scooters.

The two cylinder gasoline-powered vehicle had a safe top speed of 35 miles per hour and a 7.5 horsepower engine.

Mail carriers often complained of frequent breakdowns ranging from clutch failure to broken front axles.
