Swiss manufacturers will this week launch the futurist eJalopy GreenWheel - a bike with a revolutionary electric motor and loaded with sensors, apps, and internet connections. Users can use wi-fi links to their smart phones to find their friends for them and then tap into GPS systems to find the best, quickest or most energy efficient route there. They can also monitor their own performance, pulse and calories burned up - and send out challenges by SMS from the 3,000 bike to see if anyone can beat their personal bests. And when the effort gets too much, riders can sit back and let the electric motor - built into the green coloured rear wheel hub - do all the work. MTB Cycletech designer Butch Gaudy and computer expert Michael Lin said: We wanted to make a quick, quiet and effortless bike that runs on a simple platform that would allow new functions and apps to be added.
