The YikeBike mini-farthing is a type of folding electric motorbike released on 2 September 2009 at Eurobike, going into production mid 2010. It weighs 11.2 kilograms (24.7 lb) and when folded, it is small enough to fit in a carry bag, so it can be transported in an urban bus. The YikeBike was invented by Grant Ryan and designed by a team in New Zealand over 5 years.[1]

Characteristics[edit]

The YikeBike looks like a mini version of a penny farthing (mini-farthing). The YikeBike folds to 6×23.6×23.6 inches (150×600×600 millimetres) and weighs 24.6 lb (11.2 kilograms), so it can be carried around.

The vehicle has no chain, pedals, gear box, mechanical brake, cables or levers. These functions are provided by a 0.2 kW (0.27 hp) electric motor and controller. The YikeBike has regenerative electronic anti-skid brakes. There are also built-in lights, indicators and horn for safety.
