Each rim (even of "same" outer diameter) will be different for it's ERD, some of them by quite a bit depending on actual construction, so you'll need to know the rim specifics from it's manufacturer or seller or have it there to measure it to be sure of getting the right spoke lengths for it.Currently have this motor laced in a 24" rim. Don't want to have to unlace to make measurements to use in Grin spoke calculator before ordering rim and spokes because this is a daily use bike. Anyone running this motor in a regular 20" rim. If so, which rim and what length/gauge spokes are you using. Thx.
For the motor itself, there are posts in this thread that give measurements, such as this one
you can use this link to the archived version
and use the searchbox just above the first post to search just this thread for keywords, if you'd like to see other posts that may have this info. (depends on what words they used as to what terms to use to find them; "flange" found the one above).
