Yes, they are 9g... and they are motorcycle spokes (UCP, not stainless steel), as far as I can tell regular bicycles use 15g-13g spokes. JRH has 12g spoke but I think you would need a washer in the cromotor flange.
8 G / 4mm
9 G / 3.5mm
10 G / 3.2mm
11 G / 2.9mm
12 G / 2.6mm
13 G / 2.3mm
14 G / 2.0mm
15 G /1.8mm

What I meant was that there has been a trend just recently of using these moped rims and mbike tires; they look totally badass and I'm having trouble enjoying the look of kenda flames or holle rollers the same way. There is no doubt these are safer, maybe cheaper, but heavier and won't fit every frame; bike tires have been getting a bad rap as we push these things faster, but what Luke does with his 3-400 pound "bike"+rider weight on the track is not comparable to many other peoples situation. If you are running a hub motor on the street as a commuter I would be upgrading to get the stronger rim, not the stronger rubber, but that's just me; I have found the rim to be the week point in my hard tail builds, with a DS bike I wouldn't even be worried. Is there ANYONE besides Luke that can really say they raced their ebike to the point that the side walls of their tires failed? I will take my hat off to them as well, for I am in awe.

Here is a little wheelset that we put together for a fella in Canada. Thanks for the build, it is a nice wheelset you have coming!
17" moped rims and Gazelle tires. Should be a blast!

Just wait to you see what I have my friend fabricating for my exhibition of acceleration bike.
This is what I have now
Rides nice, corners great and that swing arm is extended 8 inches. Problem is I can barely run any phase amps into the motor at 125V because it doesn't matter how far I lean over the handle bars, it will loop me off on a hard launch. New version is most likely going to be 16" or 20" longer with a different shock mount so I can use a longer shock with a stiffer spring I already own vs this very nice 140mm Cane Creek Cloud 9 air shock so I can go hunting just about anything from a dead stop to about 50 mph Should be scary fun.

I was planing to only use a 180mm rear disc with Hope 6Ti caliper but it is too wide.
