The bike with solar wheels
Sun's rays charge batteries for 500-watt motor.
At first glance, this bike may look more like a fashion statement than an environmental one. But its wheels, which resemble spinners adorning the tires of some inner-city SUVs, are actually circular solar panels soaking up energy from the sun's rays.
The "E-V Sunny Bicycle," which claims to be "the first all solar electric bike," generates enough natural power to charge the batteries that run a 500-watt motor attached to the front wheel with a top speed of 19 miles per hour, according to OhGizmo.
The price of this 75-pound bike is fairly steep at $1,290, but there's also a kit to convert a conventional bike for $795. And if a wild mood strikes, you can even shut off the motor and pedal the old-fashioned way.
