To compete in the USA, you'd need to at least match the standards of best dealers here. So no super cheap single wall rims. Black seems popular these days. 24" is pretty rare, so make that size a special order.

Agreed with Dogman; make the structure double-walled.

Spokes: 36 hole is most common for hub motors. I used Sapim Strong Single Butted on mine. Nipples were standard brass.

Width: Wider is better. Presently I have two types in use: Mavic ES 729 Disc, and the Kris Holm 24" MtB. After recent testing both IMO are flawed.
The Mavvic is 36mm wide and with a large 2.5" wide Hookworm tire mounted the rim appears to be "narrow", and allows for side-to-side tire deflection which can add instability to the ride under high load. In constract, the Kris Holm rim is wide enough, however in an effort to lighten the rim, they added holes which presents a new problem because the custom rim tape is too thin to prevent the sharp edges from cutting the tube. Therefore I would suggest making a wide rim and have the option to have holes or not.

Strength: There should be two classes offered; lightweight for bicycles electrified, and middle-weight DOT-rated for Moped-class/Light motorcycle.

Color: Black paint or polished Aluminum.

Braking style: Make them dual-use and be done with it; both disc and rim. The side wall will add crucial strength.

Construction: Welded is IMO better than pinned. Dimpled is preferred to reduce risk of inside-rim punctures.

Balance: We should be able to balance the wheel. For bicycles this presents a problem, though less so with higher-quality motorcycle rims and tires.

Rim Tape: Offer a solidly-constructed rim tape that is tough, durable, and waterproof. For my money neoprene rubber works pretty well if you can find it.

Get this sorted and iI will gladly demo for my next build 8)

Best regards, KF
