I've been cycling with my wife and 2 sons (3 & 5) for a while now. My wife and I ride a tandem and we pull the boys in a trailer. Well, they're getting older, bigger and restless and so we need a change. We think the ideal solution would be to get a trail-a-bike that can hold 2 kids. I don't think these are in production anymore, so was wondering if anyone had one they'd want to sell. Probably a long shot, but thought I'd give it a try.
I'd also appreciate any stories/pics from those who have either used such a bike or who have come up with another creative solution for bringing kids on a ride.
