I went looking for info on one-wheel vs unicycles, and both good reads I found mentioned there are physical "pushback" & auditory warnings ahead of time in unicycles in particular. I have yet to find a great description of pushback. One-wheels by compare have a "nose up" to warn you, but seem to lack the auditory warning for no apparent reason. https://radicalcommute.com/euc-vs-onewheel/

I did absolutely enjoy my time with some onewheels, but I did experience a "sideplant" on a climb when I likely exceeded either the torque of current limit when I absolutely never expected it (and got no warning either). Definitely not fun.

I never had issues when playing with it even at top speed and hitting an obstacle, as the extremely low platform and modest top velocity meant I could always recover by scrambling forward and propelling with the front feet. The real problem happens when not expecting it, like when I was slowly climbing, and even at zero speed the fall can be nasty. I never lowered my attention even for a split second on the onewheel after this.

I never had a chance to try an EUC, but due to how the legs are used for support, I can't see the same as a recover possibility. If the EUC fails, faceplant seems inevitable.

As for the "pushback", the effect on the onewheel is extremely noticeable and didn't feel the need for an additional auditory sound. The problem, as stated by OP, is that you can have failure modes where the motor stops supporting you before "pushback" (or even sound) kicks you in.

EUCs "tilt-back" and One-wheel's "nose up/pushback" is the same thing, but it's much easier for EUCs to do because of the smaller required momentum, thus you need less power margin to ride safely.
