"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.

Unfortunately the CPSC warning is too vague to know if this is people pushing the device past its documented limits or the device failing within the standard limits.

The difference is that when most things fail (something that will happen), they do not result in instant deceleration. When your iPhone experiences a power failure it usually just doesn't turn back on. If a car experiences a power failure the brakes still work. Even if the brakes DO fail, you can still at least try to come to a safe stop—and it's possible you can.

When the power fails on a OneWheel there is almost no possibility of a safe stop. You are getting launched.

Yes, agree with you both - probability * severity. The severity is high (unless you know how to run off the board - that lowers the severity quite a bit). The probability is unfortunately unknown.

It's possible that the board just fails for any number of reasons.

I had a Boosted Board fail on me once. No idea why. It just powered off randomly while I was riding. Wasn't going downhill, wasn't full battery, wasn't a depleted battery. It was a bit scary to suddenly feel the power go out, but I was able to safely come to a stop. I was probably going about 15 MPH. I never figured out what happened. It turned right back on. This was the first time the board gave me pause. I kept riding for a few months until I did actually get hurt—100% on my own stupidity. I tried to go over some train tracks while leaning too much on the front trucks and was going fast, but not quite fast enough to cruise over them, and the wheels properly got stuck in the tracks, so I got to experience the fun of flying. Fortunately I was not critical injured, just extreme bruising. Helmet 100% saved my life though.

This is the same kind of thing that can happen with a OneWheel—only no user error is needed for it to happen, merely a power failure. OneWheel either needs an integrated solution that allows you to roll out in the event of a power failure, or some kind of redundancy to ensure the probability of a power failure is effectively zero. Anything less leads to (preventable) death.

Sure, anything can fail.

For these kind of "catastrophic failures" I think the important thing is the probability of the event.

I am not aware of evidence showing a Onewheel can fail at an unacceptable rate.

Have you ever had the power fail?

rainsurf · 3 years ago

I assume you mean the board fully power off while riding?

If yes, then no.

It is possible to overload the motor by going over the maximum speed or going uphill by at too high of a speed but in that case the board will not actually power off.

The only way the board may turn off is if is fully charged and you immediately ride it downhill (regenerative breaking). To protect the battery from overcharging the board it will turn off in that case but the app will warn you before that happens and for newer boards they have implemented the ability to charge to less than 100% if that is how you start your route.

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 Onewheel has implemented are completely adequate (primarily pushback).

I think the big problem is people not wearing safety gear and/or maxing out the board (speed specifically) too early.

This is a cool project, but I would more concerned that replying to spammers confirms you are real and that could result in much more spam. So is the net increase in pain your own?
