PORTLAND, Ore.  People who pedal to work each day have long sought a kind of commuter equality: a federal tax break for biking similar to those given for parking or riding public transit. Last week, after years of rejection, the credit suddenly became law.

Scheduled to take effect in January, the credit was among a range of energy and tax provisions quickly added to the $700 billion financial rescue.

Yet here in the district of the congressman who first pushed for the bicycle bill, Representative Earl Blumenauer, a Democrat who wears a bicycle lapel pin and founded the Congressional Bike Caucus, no party is being planned.

“Who wants to celebrate?” said Jonathan Maus, who edits a blog that promotes cycling here in Portland. “Because I think a lot of people agree with how Blumenauer voted.”
