I’ve been searching around with no answer to be found, if there is a good summary please direct me to it.
I wish to understand how do I use ERPM to speed limit my top speed on my mountain board. I know it has to so with soft ERPM limit, gear ratio and tire diameter. Rather than just playing around with the values until I get the speed I want, is there a formula I can use?
I used this calculator. You have to play around to get it, but all the info is there. Just change # of cells up and down until the speed is what you need. You can then see the rpm at which will be what you need to set for that speed.
Good info. I calculated my top speed to be around 45Kph.
It also calculated 49728 ERPM on a 7 pair pole (I am using a 14T SK3 aerodrive so this is correct). If I limit ERPM to about 25000 should I expect the speed to be halved?
