The attention city leaders have lavished on cycling raises a question that keeps popping up around the country: Who is paying for all this? And shouldn't cyclists be kicking in?

This year alone, Georgia, Oregon, Washington and Vermont considered taxing cyclists. But in other places, including Hawaii and Colorado Springs, Colo., bike registration laws have been in effect for decades.
