After a trip to Copenhagen, Instructable user carkat saw that a lot of people used cargo bikes (with a cargo area in the front) to transport their kids around. He couldn’t afford to buy such a bike, so he cannibalized a couple of junkers, some square steel tubing, and some some sort of what looks like laminated wood (he doesn’t say), and built a nice three-wheel cargo bike. [Thanks, Shawn!]
