This video is 3 minutes, shows a bike being built, and some horsing around at the 21st Ave. Bicycle shop in Portland, OR.

Description from Vimeo:

Not a promotional video. Just a fun family video to show you what to expect if you spend 3 minutes down at 21st Avenue Bicycles. Besides seeing sweet commuter bikes getting built-up you'll also get some high-fives and maybe even a sighting of missing brother Atlin. Sweet, full-on promotional styled videos coming soon! Enjoy!
