It appears that some unknown hater has begun cutting the brake lines on some of Seattle's shared bikes. Spin (the orange one) sent out an e-mail to users today that says the company has "received reports of brake lines being cut on Spin bikes in the downtown Seattle area."
Soon after, the Seattle Department of Transportation tweeted about it.
We’re getting reports that some #seattlebikeshare bikes have had brakes vandalized. We’re working w/the companies to notify users, but in the meantime, please be sure to test your bike share brakes before you hop on. More info soon!

I've reached out to the bike-share companies for more info and will update this post if/when they respond. But check those brake lines before your ride, folks. And don't forget to wear your helmet.
