Butler Petrol cycle

According to Wikipedia, this vehicle was first shown at the Stanley Cycle show in London in 1884. A remarkably advanced device, powered by a water cooled 600cc flat twin four stroke engine with float-type carburetor and using a battery and coil ignition. Apparently it could manage 40 mpg but at speeds not much more than a walking speed. Powered vehicles were discouraged in Britain at the time by the Red Flag Act and the inventor broke the vehicle up in 1896.
