Bryan and I recently finished this bike. We've showed it off (in other words, ridden it around) and a lot of people seem to really like it. The idea is to make a couple and hopefully people will replicate them to carry goods to and from the market or whatever else they need to carry (like a half a dozen kids to school).
I just bought a beat up BMX bike to build another type of cargo bike. It's going to be even sweeter.
