Any speed over 20 will make the state change the law for these motorized bicycles to be required to have a DL, register and have a license plate, insurance. etc. Anybody voting on a speed over 20 is nuts. Your not gonna get a law saying u can go over 20 without having to have a DL. Thats totally impossible. Remember they are considered bikes, therefore a bike shouldn't go over 20 in a bike lane...66cc is considered a motorcycle. Those u will never get allowed to be ridden in the bike lane without a DL, registration, motorcycle indorsement.
