sounds like you're looking at V.C. 406b, which is for electric bikes, and not 406a, which is for gas.
i know from first hand court time, and sitting on the side of the road getting a ticket-time, that we DO need all these things, and it's clearly stated in more than one section of the DMV website.
but if you've found something no one else knows about, i might just have to move to san marcos.
