Southern California Buddy Board

I'm heading down to Southern California (santa cruz/LA/San Diego) in late January/Early feb, looking for somewhere I can rent a Bike for a week and ride most days. I've been checking out some options, but looking to get advice on longer term rentals and trails to hit, somewhere where I could rent for a week and ride every day. I live in a fairly hilly part of Ontario, lots of bush riding, single track, no real mountains though.

Any advice much appreciated,
