YikeBike

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 kg 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.

Characteristics
The YikeBike looks like a mini version of a penny farthing (mini-farthing). The YikeBike folds to 6 * and weighs 24.6 lb, 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 electric motor and controller. The YikeBike has regenerative electronic anti-skid brakes. There are also built-in lights, indicators and horn for safety.
