There are a few public bike repair stations in Oakland. Some are basic (an outdoor pump) but some have everything you need to get you on your way. If you see any that are missing, add info here or create a page for it and tag it "public bike repair station" - it will then appear in the list below.
Maps of these stations are keep by the OpenStreetMap project.
The City has a bike committee, which helps coordinate and seek funding for installing facilities such as this. Private companies also may choose to install such stations, especially if encouraged by their employees.
