Both the City and the University share the same bicycle license program but there are differences in enforcement. Licenses can be obtained at TAPS office, and at the Farmers Market on the second Saturday of the month. Licenses cost $12, last two years, then renewals are $6 (for an extra 2 years). At one point you could renew at local bike shops, but that is no more.

From the TAPS Code:
Chapter 6 Bicycle Registration-Licenses Section 6.01. Licensing of Bicycles Required. All bicycles used, stored, parked or operated on the University except UCDMC shall be licensed with a valid California bicycle license. Every bicycle must display a valid state-issued sticker imprinted "California Bicycle License" including a unique registration number and a valid state-issued renewal sticker imprinted "California License Renewal" and "Date of Expiration Dec. 31, 20XX" indicating a current registration and including a unique registration number. In this chapter "bicycle" also refers to a motorized electric bicycle. Authority to create bicycle regulations on the University is pursuant to Section 21113(f) of the California Vehicle Code. Proof of ownership may be required to register and license a bicycle. Section 6.02. Impounding of Unlicensed Bicycles. The Police Department and Transportation and Parking Services are authorized to impound unlicensed bicycles or bicycles with expired licenses and remove them to an area designated for storage. Bicycles so impounded may be recovered only upon proof of ownership and after required fees are paid. No bicycle shall be released unless it is licensed in accordance with Section 6.01. Unclaimed bicycles, which have been impounded because they were unlicensed or impounded for violation of parking regulations set forth in this Code, shall be held for a minimum of 90 days at which time the owners shall be presumed to have relinquished their legal title. Such bicycles shall be sold at public auction without reserve. The same disposition shall be applied to bicycles which remain unclaimed after storage with the Police Department or Transportation and Parking Services and to stolen bicycles which have been recovered by the Police Department if said bicycles remain unclaimed for a period of 90 days. Notices will be sent as soon as practicable whenever possible to the owners of all bicycles removed to a storage area. Section 6.03. Displaying Of Bicycle Licenses. Bicycle licenses and renewal stickers shall be displayed on the front of the seat tube of the bicycle frame consistent with the guidelines outlined in the California Vehicle Code.

Although the majority of Californians live in areas where California bicycle licenses are offered or even mandated by local authorities, participation in these programs is not widespread across the State — CALIFORNIA BLUEPRINT FOR BICYCLING AND WALKING section IV.C
2009-07-31 20:28:01 When I tried getting my bike licensed at Freewheeler recently, they said that the forms they had left were for renewals. There was also implication that they may not issue either once the renewal forms are gone, so I'd call first before heading over. I went from Ken's to here, then eventually to TAPS before finally getting the license. —KevinChin
