Half of our set up (don't have a pic of my son's bike.) He rides his bike and my daughter rides the trail-a-bike - they're 7 and 3 respectively.
It's a '92 Bridgestone XO-2. I bought it from a local BF member who had taken very good care of it. He had it set up for touring for his wife. I put the moustache bars back on, replaced the saddle with this Brooks, replaced the clipless pedals with platforms and Powergrips and put the baskets on. I chose the baskets because they were a steal on CL. I love how much I can shove in them but I am thinking I'd like something I can take on and off easier. For the commute I have a bag with clothes and such, my briefcase with laptop, and a kids bag for daycare. Since we just started commuting I've decided if by August we're still going at it, I'll invest in some nice panniers.
