Cargo Bikes

mdizzle, the 8 Freights are designed by Mike Burrows. I've briefly (although not over a longer distance) ridden one owned by bikefix and quite liked it. He used to custom-make them. Don't know if he still does.

He does - or at least he was went I went to see him a couple of weeks back. Might not be ideal for transporting kids around, but they do work well for lugging hefty amounts around.
