Cupertino has 2 major streets: De Anza Blvd., which runs North-South, and Stevens Creek Blvd., which runs East-West. The intersection of these two streets is in the center of Cupertino, and most of the businesses and shopping centers in the city are located in the area.
Highways 85 and 280 cross through Cupertino. These provide excellent access to the western cities in the South Bay, and to downtown San Jose respectively.
Public transportation in Cupertino, as is the case for much of Silicon Valley, is very poor due to the low population density and demographics of the region.
Traffic is not much of an issue and major streets come with bike lanes, so biking is relatively safe.
