The 1914 Twombly Cyclecar: Almost a Toy


I have always had a love of machinery: wheels connecting to rods, pulleys connected to shafts, engines connected to wheels.

Cars: The Most Popular Boy's Toys Ever Invented

Three hundred and fifty years ago, the first steam-powered vehicle was given to the Chinese Emperor as a gift, supposedly as a toy.

Approximately two hundred and fourteen years later Karl Benz introduced the Benz Patent Motorwagen, powered by petrol: the internal Combustion engine.

Today, cars are still the ultimate boy's toy. Hobbyists research the evolution of a classic vintage vehicle and take pride in owning it and showing it. And taking it for a drive to the local car show on a weekend.

Here's a wonderful toy: the 1914 Twombly Cyclecar, small and lightweight and (originally) inexpensive, a dead end in the evolution of modern transport but the perfect pastime for those who love engines.


1914 Twombly Cyclecar

Above you see one of three known remaining 1914 Twombly Cyclecars, owned by Mervyn and Margaret Kroll-Brisbane. It was built by the Driggs-Seabury Ordinance Corporation in Pennsylvania.

What Was a Cyclecar?

Cyclecars were inexpensive automobiles, made in the early 1900s, seemingly a cross between a car and a motorcycle.

A number of auto makers manufactured these unique vehicles to address the needs of buyers who were looking for a means of transportation lower in cost than conventional automobiles. Additionally, registration taxes were based on vehicle weight and engine displacement. Lighter in weight and with smaller, less powerful engines, Cyclecars were less costly to buy and taxed at a lower rate.

The concept was that this type of vehicle offered the promise of mobility for everyone. "Speeds up to 50 miles per hour." The tandem two-seater configuration and engine type gave the impression that the vehicle was actually a hybrid type of motorcycle-automobile combination. Cyclecars of various manufacture were all powered by either a single-cylinder engine, a V-Twin enginer, a four-cylinder engine or a motorcycle engine.


A typical cyclecar, such as one type manufactured by the Pennsylvania firm of Driggs-Seabury Ordinance from 1913 to 1915, had two seats in tandem displacement and an underslung body.


Cyclecars enjoyed limited popularity for a time and were even entered in races restricted to these vehicles. During the brief heyday of the cyclecars, they were manufactured in many countries such as Austria, Belgium, Canada, Czechoslovakia, Germany, Italy, Sweden, Spain, France and England. In fact, the most prolific producers of cyclecars were English.


The End of the Cyclecar

The demise of the cyclecar was hastened by the Ford Motor Company’s Model T. Ford advertised the Model T’s advantages over the cyclecar one of which was the Ford being sold at a price very near to the cyclecar. Additionally, the Model T offered superior comfort and roadability. By the early 1920s, the cyclecar was but a curious memory.
