Dirk, Kyle, Luka, and Jeffrey "rip it up" at Boulder Indoor Cycling on Sep 23rd, 2009

Dirk, Jeffrey, and Kyle watched the "Big Boy" cyclists zip around the Velodrome

Gaylen thought it was pretty nifty too

Getting warmed up on the River Run

They then moved to the Velodrome track

Then it was time to do the obstacle course - Kyle was Mr. Bonzai!

Luka was a bit more hesitant at first, but picked it up fast

Jeffrey went for it also!

The four kids and four bikes barely fit in the minivan

That evening, Kyle went for a Mohawk look ... which would look RAD next time he's on the bike!
