With equal-sized wheels, this was the prototype of the modern-day bicycle.
John Kemp Starley, a nephew of James Starley, the man who built the Ariel in 1870 and subsequently designed a number of safety bicycles, built the Rover with equal-sized wheels. This bicycle improved the performance of racing ordinaries which had reached their limit in the quest for speed in 1884. The saddle, handlebars, and crank axle were well balanced and logically placed, and this established the shape of the bicycle as we know it today. Two or three years thereafter, the bicycle's components such as the frame material, tires, variable speed gears, saddle, and chain were rapidly made practical.
