There are a lot of reasons to like Bicycle Coffee. The company roasts its own beans — sourced from sustainable farms — and delivers them by bike. Plus, its Oakland location plays Nineties music videos on a small television all day long. But Bicycle’s most lovable characteristic is its practice of giving away free coffee all day every Friday. Although the financial effectiveness of this business model isn’t totally clear, the place seems to be busy every day of the week — especially on Fridays — and customers always seem pleased. In any case, being given a free cup of cold brew on a sunny day feels so good that it could turn your whole week around — it’s like a compliment from a stranger or free bridge admission from the driver in front of you. It has the potential to restore your faith in humanity. And on top of offering free refreshment, the cafe also has 4th Hand bike mechanics on location every Friday during the summer. They’ll tune your bike for only $25.
