Hah! I was about to suggest Seattle... 
How about the south end of the East Bay area? Fremont, Hayward, Dublin, Niles?
(San Francisco-ish, easy bike and BART access to the universe, not so expensive, flatter)
ETA: I know where you can get a recently remodeled 2-bed townhouse with fenced private patio a couple miles from two BART stations (one north, one south) with bike routes to each. For rent or for sale. Easy bike distance to Coyote Hills park on the Bay, along a MUT.
