Kent's Pacemaker

The Kent's Pacemaker was a veteran era American automobile manufactured only in 1900.

History
Offered by the Colonial company of Boston, it was a steam car which had one wheel in front for steering, and three rear wheels. The center of these drove; the others, an outer pair, could be raised to allow the machine to "coast like a bicycle". The vehicle was named after A. W. Kent, who was its designer.
