I will never ride an EUC because of a design flaw due to physics: in order to slow down you must first accelerate.

The EUC works by tilting you forward to speed up, and tilting you backward to slowdown. So the control system has to always leave a margin in case you need to slow down or if max power is reduced. But if the battery dies faster than expected or you reach a steep downhill while already at top speed...too bad, nothing the system can do to keep you from faceplanting at max speed.

No thanks. Wheels are cheap, I'll take at least two.

>>But if the battery dies faster than expected or you reach a steep downhill while already at top speed...too bad, nothing the system can do to keep you from faceplanting at max speed.

riding at top speed EUC is very dangerous in itself, Inmotion I think can do 53 mph - thats fast even by car standards.

Riding top speed is surely recipe for certain death, any small pebble can faceplant you.

As long as you ride less than max speed (I never exceed 50% of max speed and never ride on <10% battery), there is enough of buffer for a wheel to behave just as you expect.

Pushing these limits is as dangerous as pushing speed limits on car.

you surely dont want to ride speed limit on your car, do you? (my car I think can do 190 mph, but I never reached even half of it)

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.

Disclaimer: I ride a substantial 4kW standing scooter with a real top speed of 100 kph / 60 mph.

Similarly to the unicycle stopping problem, panic stopping a Onewheel also doesn't seem possible without having room perpendicular to the direction of travel. I tried it in a demo arena but it didn't seem safe except for low speed travel on very large sidewalks* with space on all sides. Downtown streets seem too iffy to attempt, limiting its versatility. Unicycle-ish travel is great if you have the balance for and room to do it.

* Powered transportation generally shouldn't impede or compete with pedestrian traffic.

I've done it, they stop really fast if you're standing on the tail. I've ridden city streets, side walks, gravel paths, and on board walks. I've had to rapidly stop more then once.

If you're coming from a scooter, you're not going to be used to how much balance you're going to use. I currently ride a scooter around (a much less substantial then your own), and if I just stand on it and press the button it'll pretty much go up to top speed and cruise. Turns can be tricky at speed but it's over all a much safer. I pretty much could ride one in the street (bike lane) on unboxing.

One Wheel took me maybe 4ish hours of practice before I attempted a street, and 2 weeks before I was comfortable unlocking it's full speed. It's not an easy thing to ride but it's really fun in a way that the scooter just isn't.

I think this is the root of your misunderstanding. To speed up and slow down, you tilt yourself forward and backwards. This is actually a strength of the EUC's physics, as it means you're always perfectly balanced for any acceleration or braking, unlike a scooter or bike that can 'throw you over the handlebars'.

I highly recommend trying one, it's my regular commuter and extremely fun.

Did you ever try one though? Is a long term rider I have no idea what you're talking about.
