Hard day to get through what with all of our minds focused on Boston. We're trying to get through it, too. Anyway, for those of you interested in making the move to two-wheeled transportation, the San Francisco Bike Coalition will host a "How to Bike in San Francisco" class.

To wit:

Learn the basics of bike commuting in an urban city and get rolling in time for Bike to Work Day on May 9th! In this one-hour workshop, we'll show you how to fix a flat and choose the right bike, clothes and accessories to make your ride easier. Then, we'll share expert safety tips and tricks and guide you to resources to help you plan your route, whether you're riding across town or across the bay.

Class goes from 6-7pm at the SF Bicycle Coalition HQ (833 Market St, 10th Floor).
