We assume that, with this many crates full of bike parts, you could fix up loads of those rusty bikes tied outside your building, or else make one gigantic steampunk bike dinosaur monster machine. A Craigslister in East Williamsburg is giving away 35 milk crates of leftover parts from a community bike school, each containing a different type of part: brake levers, calipers, freewheels, derailleurs, etc. “Not every part is in good condition, but most of it is fine. Even the broken stuff can be scavenged for small parts,” the ad says.

Also, the crates are heavy, and you need to take all of them, so gather up your bike gang to help before you commit.
