U.S. CPSC Statement on the danger of OWs
-
@onedangt The day FM announces more safety I guarantee it comes with less range.
Edit: and/or less top speed lol.
-
@onedangt said in U.S. CPSC Statement on the danger of OWs:
Anyway, if you can figure out a way to slow down the motor on a one wheeled device without tossing the rider off the front, you should immediately contact FM for a job! :)
lol... last time i 'helped' them, i got sassed, mocked, n ultimately cast aside... think they regret it yet?
-
@onedangt this is incorrect. its a two-body problem. in fact i already mentioned how to tackle this elsewhere. surprisingly low engagement in there btw? lots of 'we thought of that' n 'u cant because'... hows the vesc workin b!!?
alright. ill clariify. these are not novel problems. none of them.
if you have a motor in one machine, and a motor in another, and both of those motors operate under the same principles, you can effectively map any possible outcome of one system to a similar outcome on the other.
means i can infer with almost zero intimate knowledge of the hardware itself beyond its global parameters that one motor controller software can EMULATE another given the same capability.
all one has to do is start mapping variables. 1=3, 7=8, 3=12... u can eventually map every possible combination and literally graph it!
in other words, as onewheel motor control algorithm has a particular 'shape' that differs when compared to a very different application like a condenser motor control algorithm.
in other words, when vesc.mann started 'mapping' controller variables manually, one by one, he was simply tracing out the shape of a onewheel motor controller....
well done mr. vesc.mann... hannes. id offer him a mountain view but he has his own.

I think we've moved on from the issue being primarily the nosedive as a whole since there now appears to be some credibility a fault that hasn't been addressed is resulting in a particular type of nosedive. Subject to actual specifics being made we're kinda left waiting now. Thanks @OneDanGT for sharing that reddit post here. @biell get's a gold star too ;)
Since the warning mentioned all models it's hard to assume what this is since each have had a handful of edge case failures but none have a singular and repeated point of failure that I'm at least aware of especially during the time scale that was mentioned in the initial statement.
Guess we'll have sit tight till then
Truth be told since the CPSC seems to have clarified it's not looking to ban the product but also mentioned it's actually pretty hard for them to do so this may actually work out favourable for FM. I mean how many extra people do you think now know this "totally dangerous" electric skateboard exist and now just want one anyway.
-
@lia I agree, I don't think they would/could totally ban the OW. What I worry about is if other parts of the gov ban riding them in public places such as park paths and even public streets and sidewalks. If they can only be ridden on private property, that would kill off my rides completely! Keeping my fingers crossed the CPSC letter doesn't have TOO much influence.
GT-S > GT > Pint X > XR > +
-
@onedangt That would suck, not that it'd stop people riding them anyway ;)
-
@onedangt it's something ppl should have been focused on frankly. perhaps some representation . if i started a pac (political action committee - a 501c) who would fund it? they dont run on cheese platters lol
-
@blkdout The VESC concensus seems to be forming around 18s2p to 20s2p vs 15s3p (CBXR) so I think most people are with you about more power and less range.
-
I think it's their service model and perhaps their marketing.
Service model arguably makes people less inclined to repair their boards in a timely or reasonable manner.
That may be why they are only now selling fasteners, supposedly with "more to come" as they recently said.
Perhaps the CPSC wanted them to issue a voluntary recall so users whom may feel they were 'duped' into purchasing one can be made whole.
Just a year ago, they'd gladly tell you to cough up the cash rather than sell you a motor. Now they might have to!
-
I don't have time to listen to the discussion but FM has released a video (podcast) of Kyle and Jack discussing this. Embedded below for anyone that wants to listen.
Reddit has already discussed this and picked out some notable points so if you want a TLDR here's a link to that thread. -
So I listened to it, had a dull task to do at work so left this playing. Some key points and timestamps.
- 3:13 FM claim the CPSC hasn't actually specified to them what issue they take with the board other than suggesting the board can just eject the rider. FM has responded saying they cannot replicate issues outside just exceeding the boards potential.
- 4:18 Kyle believes the CPSC do infact take issue with nosediving and not a particular failure of the product, just the physics behind it.
- 8:12 Re-iterated, it seems the CPSC have not identified or at least shared with FM a component or flaw with any of the Onewheel models that they can fix or recall lending credibility to the suggestion the issue is still with just nosediving in general.
- 9:12 Kyle criticises the CPSC for not actually evaluating the product to find a particular point of failure. Instead they have only used reports and incidents to conclude there is a problem.
- 13:52 Kyle confirms there was a back and forth with the CPSC before the publication.
At this point a good chunk of this is mostly discussion on the letters and the importance of safety gear before getting back to the main topic. Not much that adds more to the discussion outside of what has already been said such as how other devices are more dangerous and seemingly have not been publicly called out by the CPSC.
-
43:10 Kyle confirms as to their knowledge this is not related to the GT footpad or the recall.
-
43:35 FM worked with the CPSC to perform the GT footpad recall and explains that the recall was delayed due to them actually working with the CPSC to make sure they did it right.
-
49:12 A flat footpad for the GT is released and mentioned here.
-
50:23 They also... FINALLY sell the hub bolts and some other tire changing hardware.
-

apparently they 'had' to redesign the fasteners... sure!
machine screws were ass-backwards before them.XR's got what plants crave!
-
@notsure Yeah that one was odd to me, that said if I can finally get these things from local Onewheel authorised retailers now rather than paying international shipping then I'm happy...
* grumbles in having paid big money on stupid bolts. *
-
@lia I watch all their videos on 2x speed. Slow talking Californians don't even hit NYC speeds on 2x.
-
@lia Another key point, was that GT Custom Shaping was close, and people at FM are using it. Kyle seems to insinuate that all this CPSC stuff is slowing down the release of that feature. Not sure I believe him.
Which brings me to my takeaway from this video and the emails from the CPSC representative a couple days ago. Does anyone else feel like Mom and Dad are getting a divorce, the judge is asking us to choose who to live with, and your not sure who (if not both) of them are gaslighting you about the other?
-
not sure if everyone has seen this or not, but it's pretty interesting to see FM's perspective on all this. i had to laugh that Kyle says at the beginning, "I kinda think we destroyed boredom a little too hard, haha -- i could use a little boredom right now."
