Rize RX/Pro Nylon internal gear?

[Bubba zanetti]

In riding my RX, I find it to be quite quiet. I have noticed others complaining of noise. Does the recent versions of the 620 used in Rize had steel or nylon gear? And is my quiet motor the result of being the nylon version?

The latest Ultra's, known as a M620's, all use steel gears. The early G510's, which are identical to the newer Ultra's to my understanding, came out several years ago, and had a nylon gear for the first part of it's production run, then it went to metal.

Thanks. Gears must be well machined as I can barely hear the motor over the tire noise.
I guess I will have to attach clothespins and baseball cards for some genuine street Cred.
