Sons of Science set their humorous ditty "Motherfucking Bike" to video. The result? This comedic amuse-bouche featuring a slew of San Francisco cyclist stereotypes. It could've been more pointed, sure, but it's delightful and won't bruise the chronically tender feelings of those who choose to ride two-wheeled machines of danger! Anyway, enjoy. more ›

Tonight, purple and lace, diamonds and pearls abound at the Castro, one-night only galleries pop-up along Fillmore Street, and bike partiers celebrate Pride for the second month in a row. more ›

As we mentioned earlier in the week, the San Francisco Bike Party rolls out its inaugural ride tonight. This ride meets at 7:30 p.m. at AT&T Park, starting at 8:00 and ending at Civic Center. Make sure to wear your helmet! (And Speed Stick. We kid! But not really, stinky-butt.) more ›

"We are celebrating San Francisco's freedom to once again make streets safer for everyone and look forward to real improvements on the streets in a matter of days," Renée Rivera, executive director of the San Francisco Bicycle Coalition, explained to Streetsblog. "This is the first time in San Francisco's history that this many bike lane projects are approved and ready to be striped. These long-awaited improvements will help growing numbers of people feel more confident, comfortable and safe when they bike to shop, to work and to play." more ›

SFMTA sent out this helpful flier to warn drivers about incorrectly situating their vehicles while waiting to enter the Arco gas station on Fell, a move that effectively blocks the bike lane and forces cyclists into high-speed traffic. more ›

Sunday Streets met with a Rock the Bike event at Ocean Beach on Sunday. Some sort of amplifier was attached to bikes, then said listening device was powered by the magic of pedal power. Many revelers from Sunday Streets (an event that's quickly turning into more of a cycling event, rather than a pedestrian-friendly one) stopped by to enjoy the music and dancing more ›

The benevolent souls over at Mission Mission came across this jarring, albeit all too common, story. It tells the tale of Jen, who, understanding that Mission Mission is the Dateline NBC of San Francisco, asked them for help. It seems that Jen and her boyfriend had this bike that "they both loved more than anything in the world," but it got stolen outside Safeway in March. Yesterday, however, it showed up for sale on Craigslist. (The ad has since been deleted.) Anyway, the comments section is fill with tips on how to check the DNA of your bike if you ever come find yourself in a similar situation. Jen, by the way, plans on getting her bike back. more ›

Late this morning at around 10:45 a.m., there was a bike-car accident at Fell and Masonic. According SFIst reader Alex, it "seems like a Range Rover hit a bicyclist at the intersection. The fact that this happened after the new signals is just horrid." more ›

After spending over $1 million to prove to a judge, one who ruled over two years ago that we cannot add any new bicycle infrastructure to city streets, San Francisco's massive Draft Environmental Impact Report (DEIR) for the Bicycle Plan has -- at last! -- been released. more ›

Free bicycle lights will be handed out at five service stations throughout San Francisco tonight. This is all a part of "Light Up the Night," a darkness awareness event, if you will, brought to you by SFMTA and the SF Bicycle Coalition. Since December is the darkest month of the year and bike commuters must deal with an earlier nightfall, volunteers will install front and back bicycle lights at Market Street at Duboce Avenue, Howard Street at 8th Street, Valencia Street at Cesar Chavez Street (St. Luke's Hospital), McAllister Street at Webster Street (Ella Hill Hutch Center), and Polk Street at California Street. Remember: it happens from 6 p.m. - 7 p.m. tonight. more ›

Thanks, Caltrans (or whoever), for replacing a smoothly paved bike lane with a bumpy, hand-packed nuisance. more ›

While it might be infinitely more reasonable to sleep for as long as possible on Labor Day, we plan instead to be standing at the corner of Union and Battery at 8:00 a.m. for the start of the Metromint Giro di San Francisco. more ›

We all had a great time piling on Muni last weekend, foaming and ranting about service to and from the park. But what was going on behind the scenes? We asked Muni how they strategized their service around Outside Lands. Here's what they had to say: more ›

Our neighbors to the south seem to be playing a hilarious practical joke on bicyclists here. Or is it like a guns-for-toys program, where you bring in timepieces and get a bicycle in return? Anyway, we lolled. more ›

Tire pressure has become a big deal in the presidential race, but since we commute by bicycle these days, we don't listen to NPR anymore and so we hadn't really heard about that. more ›

Tomorrow, on what will reportedly be a hot day, government officials and and local activists will ask you to bike to work to "promote pedal power." While your Editor won't be riding anywhere tomorrow, SFist Jonathan manages to pedal from San Francisco to Palo Alto almost every day, so one day out of the year won't kill you, will it? Just be sure to stay hydrated; swipe on your toughest deodorant; snap on that fug helmet of yours; and leave the indignant, self-righteous attitude at home. And have fun. more ›

If you're done with your pagan tree-worship holiday, head on over to MeTransCo's 511 Survey, and let them know just how bad they suck. 'Tis the season! You could win an iPod, as if you didn't already have four or five of them already. more ›

This was the scene the other day on everybody's favorite piece of landfill, San Francisco's Marina District. Larger version here Of course SUPER-visor Chris Daly took action to keep Segways off of our sidewalks about a half decade ago, but our law doesn't appear to stop folks from just driving around in bike lanes. (It doesn't seem to stop people from riding on sidewalks either, but oh well.) Anyway, you'll be seeing these things in... more ›

Blah blah blah soup kitchens blah blah fun-runs blah holiday schedules. All that stuff's fascinating, of course, but here's what we really want to know: Muni, where can we find all the hottest Xmas shopping deals? Aside from Dress Barn, of course. Fear not, shoppers, for Muni's assembled a guide to holiday buying, starting on the day after Thanksgiving and extending to late December. Thanks to the MTA, you are now fully prepared to buy gifts, no matter which Xmas you celebrate: the real one, the Jewish one, or the black one. more ›

Our ride home from the Caltrain station takes us through the strange, anarchy-prone intersection of Division, 10th, Brannan and Potrero streets. The other night, as we gasped for air while sprinting for the green light on our 40-Year-Old Virgin-style commuter bike, we had an unfortunate encounter with a bug. Bitter experience tells us that when a cyclist feels the splat of a gnat on the back of the throat, there is little to be done... more ›

We have incredibly exciting news about bus shelters! The city just reached an agreement with Clear Channel, your favorite company, to provide bus shelters and advertising and revenue. It's a complicated relationship, and totally boring -- like, alt-weekly-level boring -- but here's what it all means to you, the common man on the street: more ›
