Production1899–1901
Recorded originUnited Kingdom
ClassOpen motor tricycle
Earliest Brown Brothers three-wheeler from Great Eastern Street. Period-derived model tables group tricycle and quadricycle but their wheel counts make them distinct complete vehicles. No safe technical specification can be transferred from the surviving 2¼ HP Quadricycle.
