Electric penny-farthing for the 21st century

Released at EUROBIKE, the “YikeBike” by the Kiwi design team is a radical electric bicycle that just weighs 9.8 kilograms and folds to 67×56×12 cm to fit in a backpack.
Featuring a small powerful 1.2 kW electric motor and controller that replaces chain pedal, gear box, mechanical brake, cables or levers, the YikeBike is gonna be the first bicycle in the market with electronic anti-skid brakes.
Looking like a mini version of a penny farthing (mini-farthing), the vehicle also integrates lights, indicators and brake lights on a hard carbon light platform, ensuring the safety as well ease of the ride.
Intended for city journeys of up to 9km, the bike is capable of reaching the top speed of 20km/h, thanks to the high power brushless electric motor.
In short, the zero emission bi not only allows a safe and brisk ride on cramped city roads, but also lets the users play their part in sustaining the environment. The YikeBike costs $4860.
