Two quick questions; I just rolled home a free Huffy CB. I wold like to use a Grubee Skyhawk motor but I see a disclaimer that they will not sell in Calif. The other choice is the Stinger SD motor that will sell in Calif. Can I use a gas motor in Calif I have done it before. Second question is If I can get a motor is there a disk brake front brake available that will fit to the Huff wheel? In my last build I did use the Stinger and am willing to use it again I am just asking about the Grubee.
