Interesting development!
2013 -
BILL A1618A eBike Assembly Bill
BILL A5058 Duplicate? eBike Assembly Bill
Bill S390 Senate eBike BILL

Strange is the duplicate Assembly Bill of nearly identical structure!
Sad ... is that each Bill has a single, lonely sponsor!

Wait! ... miracle of miracles!
There is yet another eBike Bill ... effectively.
BILL A6659: Defines the term power-assisted bicycle
Same as the other eBike BILLS except ... it also allows gas motors (up to 48cc).

Someone is making a concession to the oil industry?
Who is the lacky sucking at the teat of the oil industry ... lets look!

OMG! While any other eBike Bill has 1 lonely sponsor, the gas bike (Smog Hog) Bill has sponsors falling all over each other, trying to claim credit (garner oil donations?).
"A6659-2013: Sponsor: Oaks / Multi-sponsor(s): Ceretto, Corwin, Crouch, McLaughlin, Montesano / Co-sponsor(s): Barclay, Walter "

Definition of Power-assisted bicycle -
"S 102-C. POWER-ASSISTED BICYCLE. A BICYCLE WITH TWO OR THREE WHEELS
WHICH HAS A SADDLE AND FULLY OPERATIVE PEDALS FOR HUMAN PROPULSION AND
ALSO HAS AN ELECTRIC OR INTERNAL COMBUSTION MOTOR. THE POWER-ASSISTED
BICYCLE'S MOTOR SHALL: HAVE A POWER OUTPUT OF NOT MORE THAN ONE THOUSAND
WATTS OR HAVE A PISTON DISPLACEMENT OF NOT MORE THAN FORTY-EIGHT CUBIC
CENTIMETERS; BE INCAPABLE OF PROPELLING THE DEVICE AT A SPEED OF MORE
THAN TWENTY MILES PER HOUR ON LEVEL GROUND; AND BE INCAPABLE OF FURTHER
INCREASING THE SPEED OF THE DEVICE WHEN HUMAN POWER IS USED TO PROPEL
THE DEVICE AT OR MORE THAN TWENTY MILES PER HOUR."

Please notice this limits motor engine size to 48cc, fairly common for 2 stroke engines.
However, this excludes the more efficient, less polluting, better fuel economy, 49cc 4 stroke engines!

On purpose?
Some "conspiracy" to limit fuel economy?
Trying to make sure oil consumption isn't reduced too much???
