Last year's BK Bike Jumble. Photo by Flickr's Dancing Weapon of Mass Destruction.

We’ve got flea markets coming out our ears here, so what’s one more, especially one that can get you an affordable, new-to-you set of wheels? This Saturday is the biannual Brooklyn Bike Jumble at Old Stone Park, where vendors and collectors set up tables and sell all sorts of things, much like your regular flea market — except everything is focused on the bike-avore: small parts, frames and forks, clothing, wheels, energy food and bikes themselves. You could even land a ride for cheap: Recycle-A-Bicycle techs will be giving free estimates. So if you’re trying to sell, they’ll give you an appraisal so you can price fairly; if you’re looking to buy, they’ll inspect and diagnose any problems so you can figure out if you’re getting ripped off. There’s also an outdoor dance party from 4-7 and then an outdoor screening of bicycle-related animation and shorts from 7-9.

Brooklyn Bike Jumble, Saturday, 10am-4pm, Old Stone Park, Fifth Avenue at 3rd Street, Park Slope.

Dancers from the Cynthia King Studio and their vegan slippers (and a sheep).

We’re actually being told to “be there or be square” for the Greenwood Playground Spring Flea Market and Tag Sale on Saturday, and we’re inclined to believe it. This is no ordinary flea the Friends of Greenwood Playground have put together, but a MEGA-Flea, with live music, live dance from the Cynthia King Studio, discounts for local restaurants, prizes, a book-swap and even worm-composting lessons from the Botanic Garden. And, oh yeah, probably a ton of stuff to buy from the vendors selling “treasures, joyous junk, and everything in between!” All this, from 9 to 5 at the playground. We’ll be seeing all you non-squares there.
