This Eurobike, also called the Yike Bike, was just released a week ago today. It weights a mere 9.8 kilograms and folds down small enough to fit in a backpack. It has a powerful 1.2 kW electric motor, a controller that replaces the chain/pedal and all that goes with it. It is the first bike to hit the market that has electronic anti-skid brakes. It also has lights, indicators, and brake lights! It's top speed is 20km/h and is intended for city rides of up to 9km. Major downside, is the $4860 price tag!
