Welcome to the forum and what the heck! Stalling on a steep hill. That could be dangerous. Hopefully that was a break in glitch and nothing more. Sounds like you were riding in some beautiful country.Two rides on my 2021 DCT
1. 3-days in the mountains of northern NM and southern CO
2. 1-day just outside of Salida CO
Love the bike so far, other than the issue of it stalling on steep hill - ouch!
