You want to help the environment by bike commuting, but your workplace is just a little too far to pedal?  Schwinn Bikes may have the solution.  Their 2007 World GSE bike model combines a conventional hybrid bike with an electric motor.  While the electric drivetrain adds about 10 lbs. to the bicycle, it provides enough power to go up to 60 miles on a single charge.  Once you get to your employer, you simply remove the battery pack from the rear rack and charge while you work.  The suggested retail price is $1699.99.
