The ultimate embodiment of San Francisco's DIY spirit, local resident Nick Normuth custom-built a bunch of bikes, studied up on the city and started a cycling tour. The adventure begins in an adorable headquarters in SoMa, and branches out to the Mission, the Castro, Golden Gate Park and beyond, depending on which tour you've signed up for.

There's a general tour, a food and murals one, and a Golden Gate Bridge crossing add-on. Nick leads every tour personally, and his deep knowledge and effervescent delivery make them truly outstanding. The bikes are in mint condition and come with helmets. Snacks and water are available for a small fee.
