Can’t see anything wrong with this idea:
Paris is set for a transport revolution this weekend when a fleet of 10,000 self-service bicycles hits the city, providing a cheap and fun alternative to the metro for Parisians and tourists alike. Pedal Power Revolution Hits Paris
Bicycles are in for a huge surge in demand. Cities could benefit greatly by reducing car and taxi usage with bicycles.
The only thing wrong I can see with this is the 50 lbs bikes! Yikes! My road racing machine was 19 lbs (sold it), and a mountain bike I built last year weighs about 27 or 28 lbs. A 50 lb bike is probably made from black pipe and concrete… But who’d want to steal such a contraption?
