Are you missing work because of the broken arm? If so, that probably hurts worse than the bone. Looks like a clean break, and they got it good and straight. Will the screws and plate have to come back out, or will it stay. When the cast comes off, work that wrist a lot. If you don't, you'll loose some movement.
Is the bike insured? What are you up to in repairs.
Man, that was bad timing, that temporary sign fixture thing. Could have been a whole lot worse. I don't commute, or ride "big" roads on the bike. Vastly out gunned.
