I need some help from all the parents out there. What kind of bikes do your kids ride?

My twins started on Strider balance bikes when they were 18 months old, and now at 4.5 are completely rocking their 12" Huffys. Some of you might have seen them at Sylvan and Scott County. Now they've grown enough to warrant the move to 16", and I want to get them something a lot better than a 30 lb hunk of junky steel. They don't put chromoly on the kids bikes that I've seen. I want good materials, hand brakes, and a freewheeling rear hub.

I've seen the Little Shredders posted here a while back, those are a bit of overkill for me. Islabikes (www.islabikes.co.uk) in the UK makes exactly what I have in mind, but they don't ship to the US. Spawn cycles in Canada (www.spawncycles.com) also gets it right, but two bikes plus shipping will be almost $800. I'm crazy, but not that crazy.

Any other suggestions from the collective wisdom of FORC?
