The bakfiets is an incredible machine. I was turned onto these bikes by Josh Muir of Francis Cycles. It is the ultimate for every day errands, grocery store trips, and hauling children around. It fits in the bike lane, it is nimble and quick, and is a pleasure to pedal. I am loving it and seriously think a car free society will rely on these puppies in addition to normal bicycles.
After trying a trailer, backpack, and rear seat, I think the bakfiets is the best way to transport children. Although there are some concerns...(see step 6 for some ideas on the safer ways of placing children in the box).
This instructable is all about how to design and build a bakfiets style cargo bike. The design tips apply to any bakfiets style cargo bike and there is no need to build it out of bamboo. I like the ride quality and uniqueness of bamboo. However, if I do it all over again I might use steel... Building a bakfiets is like building three normal bikes. The amount of epoxy and sanding seemed to add up. I think my next bike may be fillet brazed steel.
Here is the breakdown:
Cost: $600 (including components - mostly used)
Time Frame: 4 months

Epoxy: West Marine (I used West Systems but I think I should have tried this: http://www.entropyresins.com/products/super-sap-clr - half the price of West System 105)
Bamboo: local bamboo nursery

The art of building bamboo bikes has really come a long way. I have realized that my technique from 2008 is probably not worth emulating. I strongly recommend that you look at the Bamboo Bike Blog and other instructables for the next level of building with bamboo. I particularly like this instructable by kentdvm:
