The S19 Pro.
I ran the 1.88 update a couple hours before going for a ride, the battery was somewhere at 80% when I left my house.
Most of the ride prior to the cutout was on a slight down hill, but as soon as the road started going up hill and I leaned to maintain speed (15ish mph), the wheel completely lost power.
I didn’t accelerate much at all, just to keep up with my girlfriend on her scooter which is not anything powerful. So it’s not like I overpowered the FETs.
This wheel has been my favorite so far, never had any issues with it, always kept it clean and well maintained, I’m not an aggressive rider so I never pushed it to the limit, just puttered around town with my gf.
I got this wheel specifically because the 50s cells and smart BMS, I previously had a v12HT and got rid of it after hearing about all the cutout issues with it. I wanted to upgrade to a wheel with a higher safety margin, joke’s on me tho…
Later that night I got a notification from the KS app stating that people should not install 1.88 and instead update to 1.90 which is just a v1.85 roll-back.
