Something like a velocipede
An elderly gentleman has invented a one-wheeled velocipede, which is quite a novelty. It does away with seat, pedals, brakes and all. There is a crank attached to the axle on each side of the wheel. You sit between the spokes and turn the crank with your hands. The rider goes round with the wheel, turning a somersault at each revolution. The sensation is therefore peculiar and the ride is much more exciting than on the ordinary velocipede. The objections to this style, is they can never be used by ladies. – The Velocipedist.
