I was planning to check but your post made me actually do it (it's really easy) : 49.9V on both rear packs and 50.1V on the two front packs, seems ok then...I'll adjust the app then.
Great wheel btw, I can now climb up and go down all the steep MTB trails in the nearby forest, which I couldn't do with my S18. I really like the tire, it's better than the CST 186 I have on the S18. No issues on asphalt (apart from the noise), great in muddy puddles...
No issues with the suspension out of the box, it's maybe a little stiff (adjustment knob completely loose, at 210 PSI for my 85kgs geared weight). I have the coil one recommended by Marty, one day it will be installed...as will the bearing caches (bearings seem quite well protected by the existing rubber seal, I added some marine grease on the seals, it picks up some debris now...)
Didn't get the kickstand in the box, hopefully my AliExpress seller (Road Knight Store) sends it over...
