johnrobholmes said:So I'm going to work on making alloy nipples this week, hold me to it guys! Should drop considerable weight. I'll also eyeball making a jig to drill or mill rims into lighter specimens. That should be an "easy" 300 to 500 grams per rim. I wouldn't mind dropping a few pounds of rotational weight on my next bike either.
chunder123 said:whats size rim is best for an 8kw 83v motor either 19" or 21"? 19" motorcycle rim is 24" with tire and 21" rim is 26" 3/4" 68cm with tire. what is the best front mtb wheel size to use with these motor cycle rear wheel rims? either 24 or 26" would a 27.5" front mtb wheel work better than 26" from the 68cm rear wheel
Rix said:Yah, the 17mc rim with the 3.00-17 sr241 is my favorite off road only combo with a 24mtb on the front. Lots of mechanical advantage with that rear tire. Climbs well. The 18x1.4 rims running either the 3.00-18 VRM021 or SR241 is the best of all worlds. Looks closer in size to a 24MTB, smaller than a 19, which gives a little mechanical advantage. I like this size so much, that I have purchased 6 18x1.4 rims which I am running on my Fighter and next several builds.

was about to write in to ask exactly this question, but youv pretty much already answered it for me there.
im considering getting a large shipment of moto rims and would love any input as what the best all round size would be.
i like the 18" as an allrounder too, but getting tyres that size seems to be much harder in Aus for some reason. its all either 19 or 17.
getting tyres from o.s. is crazy pricey on post, so i want to avoid.
i was going to go with 19x1.4 cause they look like a 24mtb, and have a little advantage over the 26 size.. also better approach angle than the 17" which might look a little starange too..
any more input greatly appreciated.

If choosing 2 ply tire, 1.4" wide rims, your custom nipples and hopefully lightweight alloy spokes the overall weight savings can easily be around 2 kilos +. And with all of that weight savings being farthest away from the hub it should really have an impact on handling.
Maybe that weight saving would even be noticeable for hubmotors?

Alloy, Ti and carbon spokes have all been tried but rarely with much success. If you want a lighter spoked wheel, stick with stainless steel but go thinner diameter to save weight and butted to gain strength from the cold forging process used to slim down the spoke's midsection.

I should charge more because of how long they take to machine, but at the same time I don't think $2 each would be an attractive price for people.
They sized up to have an 8mm socket drive on the back. Now to decide on 5mm or 1/4" spoke wrench size. What say yall, if the body allows for 1/4"?
