Ok. But then unless you're hand making the bikes out of wood you scavenged from fallen trees and don't use rubber tires, neither are bikes.
Like many pro cycling articles this one is one sided and assumes there is one solution to our environmental problems. Sure, we need people to cycle more, but we also need electric cars, changes in how and where we live, changes in what we eat, etc.
Probably the fastest way to impact all of this is internalizing the cost of carbon into all of our activities.. ie a big fat carbon tax.
