I have flown into SFO with a bike lots of times.
Unless you have a hard case with wheels, it is tough to schlep around your bike and all the gear.
Assembling in the airport is tricky because of space and, sometimes, grumpy security.
If you have the $$$, a taxi to wherever you are going is easiest - but super expensive.
If you are getting in in mid-afternoon - unless it is a weekend -
By the time you clear customs it will be rush hour.
Bikes are not allowed on BART (Bay Area Rapid Transit) during rush hour.
Otherwise, BART is great since the station is next to the international terminal.
I always try to stay awake until sundown when I fly Europe to N. America.
It's the best way to get my body into the new time zone.
Have you heard about the hostel at Golden Gate National Recreation Area?http://norcalhostels.org/marin
It's across Golden Gate Bridge and would require some riding -
But you could watch the sun set into the Pacific from the cliffs.
It's about an hour ride back to the ferry terminal - Baylink - to Vallejo.
The 11:30 ferry from Pier 41 gives you morning time in San Fran -
then you have 6-plus riding hours after arriving in Vallejo.http://www.baylinkferry.com/
(If you do take BART - get off at Embarcadero and ride the Bay Trail across Golden Gate Bridge.)
PS - I stand corrected - didn't know about SFO's bike assembly stations. Soooo San Fran & nice.
How long have they had them?
