I broke another spoke this morning so it will be time to rebuild this wheel as soon as I get some time. So I can start sourcing parts I'd appreciate any guidance on the following points:
* Spokes: 13 or 14g stainless steel, Sapim, DT Swiss etc?
* If using the original rim (had 12g spokes) I need washers under the heads?
* Washers should be used at the motor end to ensure the bend in the spoke is hard against the motor flange?
* What is stronger: The original double-wall narrow (23mm?) rim or a decent quality single wall rim in a wider size? I'm running 2.25" tyres if it makes any difference.
JRH is probably the best sorce of spokes. Being a fellow ebiker, he knows what we need.

See if he can get 13-14g single butted spokes. they will be stronger. If not, 14g are perfect for an Ebike. Sapim, DT Swiss and Phill Wood are what I use, I prefer DT Swiss.
Yes. It's either a #8 or a #10 brass washer available from Lowes. I forget which, but it's a perfect fit on 14g spoke nipples.
No..ish. A propperly built wheel should never put tension on the spoke head so the washer's are totaly un needed. But if you go with 14g and you're not an experianced wheel builder then the washers may help you get better results. This is one of those "
If you think you need it, then you do" situations. So get some. And if you end up not using them, don't sweat it.
that depends on the brand. I would vote for C, none of the above. get a good double wall wider rim from a reputable company. Alex, SunRingle, Mavic, Velocity, ect. 29mm to 39mm is good for most ebikes, but measure your frame to be sure it will fit.
