The Red Bug, later marketed as the Auto Red Bug were a vintage era cyclecar automobile manufactured by the Automotive Electric Service Corp. of North Bergen, New Jersey from 1924 to 1930.

Manufactured in Lafayette, Indiana, by the American Motor Vehicle Company, from 1916 to 1919, A. O. Smith sold the rights to Briggs & Stratton who marketed the cyclecar as The Briggs & Stratton Flyer.

When the supply of gasoline engines ran low, a 12 volt electric version was produced.

The electric version was built with four wheels, with one rear wheel driven by a Northeast electric motor, the same motor used for starting on contemporary Dodge Brothers automobiles.

Priced at $150 (equivalent to $2,667 in 2023) from 1924, the small automobiles sold mostly as a novelty for the wealthy, but also for transportation within resorts and at amusement parks.
