What a lovely month for riding bikes it has been. Cyclesomatic 2011 wraps up this week. Here’s what’s going down.

Wednesday, Oct. 26, bike to City Hall with Councilman Scott Griggs. Meet at Oddfellow’s at 7 a.m., and the group will ride across the bridge to Union Station at 7:30 a.m.

Oak Cliff Bicycle Co. offers a free bike maintenance class Wednesday at 7:30 p.m. Learn how to change a flat tire and some basics of bicycle maintenance.

Saturday, Oct. 29, is the last day of Cyclesomatic, and there is a cyclocross race at Rosemont Elementary School. Cyclocross is a cross between a road bike race, a mountain bike race and idiotarod. It starts at 10 a.m., and this one has a Halloween theme, so they’re calling it “Spooky Cross.” There are free races for children and first-timers at 1:15 p.m. Show up to race or just to jeer the competitors. It’s a good time.
