[edit] Characteristics
The YikeBike looks like a mini version of a penny farthing (mini-farthing). The YikeBike folds to 6 x 23.6 x 23.6 inches (150 x 600 x 600 millimetres) and weighs 22 pounds (9.8 kilograms), so it can be carried around.
The vehicle has no chain pedal, gear box, mechanical brake, cables or levers. These functions are provided by a 1.2 kW electric motor and controller. The YikeBike has electronic anti-skid brakes. There are also built-in lights, indicators and brake lights for safety.
It is not believed to be street-legal anywhere in the world.[2]
