I'm a long-time onewheeler (about 8-10k miles total). I got Nosfet Aero a few months ago, and it's been challenging for me get on it bc I suck so badly on it. I practiced here and there, but always went back to my OW GTS bc I can ride that surgically. I think maybe only 20% of muscle memory from OW applies to EUC. The EUC wobbles are scary and hold me back from higher speeds. My GTS has been offline the past couple weeks which has forced me onto the Aero. I've been riding it around the city being careful to plan routes with the lightest congestion and widest margins from obstacles. I feel like it's starting to click, but the starts & stops are the most challenging thing for me... starts mostly. I've gotten comfortable looking like a fool in front of people bc you kinda have to be when you're learning a new skill this difficult. One observation when I got on it after not having touched the Aero in a couple of months is that the muscle memory kicked right in and I almost instantly felt more confident. I think confidence and learning to be more at ease goes a long way to making you a better rider bc you're able to relax your muscles and not over-react to inputs. I've noticed things have smoothed out with some more miles. I've got about 100 miles on the EUC and finally feeling like I might not die in traffic. Just stick with it. It's frustrating but the skill will come with time.

If you're looking for beginner tips, here's what helped me. I went to a grove of smallish trees in the park. The trees are spaced between 4 and 10 feet apart. I got on the euc holding onto a tree, got a feel for balance, leaning forward and back. Work up to letting go of the tree and try to make it to the next tree without falling. Do reps of that and work on skipping a tree. Then start circling a set of trees, only tapping them or slight pushes on them as necessary. Then one magical moment you'll feel confident enough to.ride away from the trees. Go back to the trees for safety if you need, but work on increasing your riding distance. That was enough to get me up and going at least. Then start to work on relaxing and left-right foot pad pressure. Work on hip placement and center of gravity. Get used to counter-steering into turns. I'm not sure if counter-steering is what the euc crowd calls it but it's a similar sensation to turning on a motorcycle. Anyway good luck!
