Do segways have a similar problem or is the vehicle large enough that it can always counter balance your weight?

All self-balancing vehicles have the same failure mode -- that you can exceed their ability to catch you by leaning too far forwards.

The Segway benefits from having a big pole it can jab the rider with to make them learn back. But it's entirely possible to nosedive one if you try hard enough.

One issue I've noticed with these new forms of electric wheeled transport (longboard, transverse and longitudinal one-wheelers) is that the people riding them often don't come from a sports background. They aren't "safe" devices exactly - it takes skill to pilot them, and when things inevitably go awry, it takes good reflexes to avoid damage. Novices to action sports often throw their arms out to catch themselves whe…

Knowing how to fall is such an incredibly important life skill, it's baffling to watch people who never learned it. As a ski instructor, you could instantly tell from their first fall the kids who would get it and stick with it from the ones who would be sitting in the lodge pouting after an hour.

I know how to fall (intellectually). How do I translate that into the real world? I took a nasty fall on my MTB this summer, broke my shoulder. Everything was instinctual and a blur. Can we somehow retrain our innate responses?

I strongly disagree with this recall. I own a Onewheel (XR) and have ridden nearly ~1,000 miles on it in a variety of conditions. I've only had one incident and it was entirely my fault (riding at night without proper lights and hit a pothole). The Onewheel definitely has a learning curve. Like most things in life if you are patient in learning it and respect the limits it is entirely safe. I think the safeguards One…

"I have never had a problem therefore there is no problem"

If you actually read the complaint you will see several product safety issues (such as sudden stops) that cannot be solved by wearing a helmet or learning to ride.

My children's grandfather is very good at sports and balancing and has been riding onewheels for as long as they've been around. My kids learned from him quite a while ago. Couple of years ago they each got a Pint from grandmother as a gift.

They always wear helmets but we had a hard time getting them to wear wrist guards, that is, until one of my kids pushed it to the limit downhill in a park, rode over the pebble, wiped out and broke his wrist. His app said he hit 17mph. Since then, there hasn't been a ride without helmet and wrist-guards and they ride around quite a bit, to a store, around the city, to the park, just for the hell of it.

Breaking his wrist sucked for him but was a great teaching moment for the rest of his life, to wear right equipment for the job.

They always comment on people tooling around without helmets on those wheels or scooters. We as parents have a small success right here.

onewheels suffer from a problem known as nosediving in which the board shuts off when it can't supply enough power to support the rider, as the board is self balancing this is a problem intrinsic to the board's form factor. The board works in a similar fashion to balancing something like an umbrella on your hand, as the rider leans forward it creates an imbalance that requires the board to accelerate in order to keep…

Isn't this similar to what ultimately shut Segway down? People were falling nose first on those too.

One issue with the skateboard style of e-wheel is that your feet are perpendicular to the direction of motion. This means when the wheel quits or you hit a big bump you will have to turn 90deg before you can run. The unicycle style where your feet are parallel to the direction of travel is much easier to "run-out" if the motor quits. The unicycle style also allows a larger wheel and larger batteries. I think reason t…

Didn’t you basically train yourself on how to run out on an EUC while learning? I know I did.

Also the EUC feels so ridiculous that wearing protective gear seems normal.

Earlier quoted context omitted.

Bug is a bit of a misnomer, it’s a constraint by the laws of physics due to the board having only a single wheel. If the board is being pushed beyond operating capacity, there is no graceful way to slow it down without the rider cooperating. If the rider never cooperates and the motor overheats, that’s when you see a nosedive.

then FutureMotion must equip all onewheels with safety wheels on both sides. Also called as Fangs bumper wheels. physics is no excuse for lousy engineering from FutureMotion and complete disregard of life threatening diving condition!

But then it’s a fivewheel! /s

- "you could instantly tell from their first fall" Mind elaborating what it is you see?

>Mind elaborating what it is you see?

A lot of people just fall. Like a sack of potatoes. Their inner ear senses a point of no return, and they just let gravity take over from there.

Other people sense the fall, and react, but they are still just trying to stop the fall from happening, so they break their wrists on impact.

But usually anyone with any kind of athletic experience or decent kinematic awareness understands that the fall is happening and the point is to direct it. The elbows tuck, the neck lowers, and they guard the body while directing the inevitable fall.

As with every other skill, practice.

Judo and skiing taught me how to fall. It's easier if you start young because you have less distance to fall.

I bailed at 8mph on an electric longboard and broke my elbow, severely sprained my shoulder and wrist. I even lost some rotation and dexterity in my hand. It's one of those my arm is never going to be the same type injuries. I was 40 but skated and bmxed into my mid-20s and still felt pretty comfortable with my abilities on the ground (gave up on ramps long ago). I knew this was a risk given the speeds and even got a…

Is there something more inherent that makes an electric unicycles more dangerous, other than they make them go ridiculous speeds?

I would have thought the larger wheel on an EUC made it more stable and the higher power makes it not have to nosedive. I kind of prefer e-bikes because they are well… normal.
