Big Wheel at Urban Assault RideIt’s Bike to Work Week, which means it’s the perfect time for you to dust off that two-wheeler and start pedaling (or feel a bit smug-er about already being a committed cyclist). For tips on converting to a cycle-based commute, check out our handy how-to or the entertaining Umbra video at the bottom of the post.

And for those of you with a more adventurous spirit, check out the Urban Assault Ride. Sponsored by New Belgium Brewery (makers of Fat Tire ale, natch), this bike-based scavenger hunt will send you all over the city in a race to complete a series of obstacle courses and other challenges before hitting the beer-tent after-party. There’s no limit to the creativity of these folks, with past events including bike jousting, big-wheel-ridin’, keg walks, limbo, and more.
