Deckhand or similar for RadRunner?

[Bosus]

Loving the RadRunner we just bought. I already had a Juiced CCS for commuting, but this is a great supplement - simple, fun and inexpensive. I took my son for a ride this morning, and while he was comfortable sitting behind me, I wish there was a handle for him similar to the Deckhand for the RadWagon. Has anyone seen anything that might work?

So here's what I worked out: a threadless handlebar stem mounts to the seatpost with a little beer can shimming, so now my kids have something to hold. The tassles... let's just leave it at I love my children.

I need to add an handlebar to my RadRunner too. Do you mind sharing where you found the one you're showing on the picture?
