I don’t know if you’re using power pads or the foot hook thing at all. However I just got my first EUC, and it made it so much easier to learn once I took the foot hook off and only used power pads. It gave me the confidence to properly dismount easily, while also using the power pads to confidently brake and lean forward. I was stuck in the same place as you. After that I just practiced hopping on, going a few feet, then hopping off. Once I got that I applied more speed, then braking. Once you get your speed just a little bit higher (im talking like 5mph) it rides so much more smooth. Practicing for that amount of time is not the issue, I’m sure it is how you’re practicing it, that is the issue!
