In February of 1891 Frank Weston of Bangor Maine, a long time wheelmen, patented the Weston Fork Cyclometer for safety bicycles. The Weston was mounted on the left front fork. It could be used on a solid, cushion, or pneumatic tire safety bicycle. This cyclometer was used for a 30 inch front wheel, the common size for the time. Weston's company was short lived (2 years) and went out of business in July of 1894.
