Sadly, no electric bikes are allowed on MidPen trails here in the south bay.
The MTB forums are filled with a bunch of e-bike hating bitches who will tell you otherwise, but they are allowed if, upon being asked by a LEO, you verbally state that you have impaired mobility, and that need seems credible (e.g, the LEO didn't just spot you landing a 6 foot drop off.) It's all in the midpen mobility device guidelines (same for EPRPD.)
