Better Nosedive Warning



  • After riding a bit with the beeper I do not think an audible beep sound is right way to do it. The beeper would really only beep when first setting off and going up hills. The beep was also very annoying. It never beeped at speed, anything greater 10mph, push back does a really good job keeping you safe. If there was ground detection sensor, then that could keep the nose of the board from touch the ground by "pushing back" and give you some tilt bias. So push back before the nose hits from a range sensor. The ToF range sensor is pretty good at that. On level ground the board does a great job, but no always up hill. Elevate gives it a tilt bias nose high but isn't good on level ground. I go up a couple hills on my commute but don't bother to stop and change setting. Plus this little guy makes the boar look ugly so I rode with it a few times to see what it was like then put it back on the "has been" project shelf.



  • This has all been suggested many time before. I'll probably sound like a broken record but I don't care: riding technique and foot position are sufficient to avoid most nosedives, rather than trying to make the board smarter (which actually adds software complexity that makes the board less awesome).

    1. Set your feet farther back, so your front foot's heel is closer by the wheel, and your rear foot is almost at the back edge.
    2. Go more slowly up hills
    3. do a half-hop aka "get light" when you go over a pothole or a large bump

    I used to nosedive all the time, I used to blame the board and it's design. Then I started doing these 3 things ^^^ and realized I'd be fine.



  • @skyman88 The beep wouldn't occur as the nose dove, it would occur at maybe 90-95% power output, and would also not require as much power usage because it wouldn't need to physically lift the rider back while the motor is already under stress at near max speeds. An option for it would be great in the app for new riders to learn the board's limits. It could be turned off for those who don't want it on. Personally I'd love this feature.



  • @skyman88

    I think the technology should slow it self down in balance, Simply shutting off is weak. I would have preferred an audible signal that increased with frequency and volume before shutting down. It would be like driving your car past the empty signal - Sure some people are going to really push it and run out of gas - other ( Most) will slow down before failure



  • @readysetawesome
    This is great advice for nose dives - and really works. Thank you and keep posting this because it is works ! The Wish list items is for a better "shutdown" system. This nose dive is when the Onewheel shuts off at 10- 15 mhp - and rider nose dives !



  • Although I agree that there should be a better warning, as when pushback occurs it leaves some play room where those of us concerned like to ride, the "fixes" that are being proposed don't make sense from a physics standpoint. The best fix would be a stronger motor; I want my onewheel to go 50 mph but I'm nuts (half joking). As it stand now, the device simulates pushback by decreasing the threshold dip on the X-axis on whatever side you are leaning, all the while, it is trying to maintain that speed, or if you continue to lean it is then trying to give you that speed in order to keep the board level. 99% of the time the nosedive occurs because of the latter scenario; the board simply does not have enough power to give you in order to maintain that balance. If you cannot understand that the machine giving you momentum in whichever direction to counter the weight/lean you are placing on the board, then you do not understand how this board works.



  • I don't know what the fix is, but I stopped riding the onewheel after nosediving 3 times when I took it to burning man. I've never ridden it before or since. The first time it nose dived I ran it out ok. The second time it nose dived I judo rolled out, slightly painful. The third time I slammed my wrist, hip and shred my knee. This was all on dirt, had it happened on concrete I would have ended up in a hospital. When I have time I'll learn the basics slow with kneepads, gloves and helmet and learn how to bail with it on dirt. I doubt I'd ever ride it on the street, maybe in the suburbs, not the city. We'll see, maybe these things can be improved.



  • @craigmo said in Better Nosedive Warning:

    I've never ridden it before or since.

    Sorry for your pains but, and don't take this in the wrong way, this one sentence will sum up why you nosedived; there is no fix for what occurred other than you take the time to learn the board and respect it the way you should any other boardsport.



  • +1 for an audible warning please - maybe adjustable via app.

    I’ve put a few hundred street and trail miles on mine and thought I knew how to ride but just recently had my first nosedive going down a mild hill maybe 12mph 30% battery and it just launched me off onto asphalt without any pushback warning. I’ve gotten pushback before around 16mph but not even sure - maybe drop a notification on pushback so I know for sure it’s been triggered to learn what it feels like.

    I guess leaning too far forward could have done it but didn’t seem like I was and there was no pushback warning - paranoid of this reoccurring as it was a painful crash gonna take months to really recover.

    Afraid such a warning feature basically involves having testers try to crash maybe need an articulating crash dummy on a dynamo.



  • @Aaron
    On an XR? 30% battery seems to be the threshold for performance decreasing on them.

    I'd love to hear that audible beep while in the air...



  • Pad up people. Without a nosedive warning this is your best bet.

    I recently had my first overcurrent shutdown while navigating tree roots on a downhill trail. That is essentially an instantaneous condition - there is no way for the board to pre-warn because when too may amps of regen power hit, the board has to shut down to protect the batteries.

    I didn't actually fall down but with pads everywhere I would have been good to go. No software testing required to verify pads are great: they can be the difference between just getting right back up and going to the hospital.



  • @readysetawesome I'm curious to hear about the overcharging shutdown with OW's because it seems actually like a quite common thing. Does going down a relatively big hill charger your OW up quickly? There's quite a steep hill about 200ft long near my house, and I use it to get to a bike trail. When I get my OW I don't want to go down the hill knowing that it could shut off depending on how close to 100% I am.



  • @zapp I think I read somewhere that you should go up a hill a ways or find some other way to burn off some juice and to not hit a downhill with more than 95% charge.



  • @skyman88 yes it’s an XR and it was the first time I had ridden it with battery lower than 45%



  • @zapp I don't think overcurrent shutdown is common - and to be clear what I was describing "overcurrent" can happen no mattery what % your battery has remaining. It is different from "full battery shutdown" or pushback.

    But to your question, going downhill can only regenerate, best case, maybe 10-15% of the power expended going up the same hill. If you live on a hill you can solve this by backtracking a little, it really doesn't take much. I live on a moderate hill and I never get the full battery pushback, my driveway has a short steep incline that helps me shave some voltage off before I go down the block and begin my descent.



  • I would like to see a push notification if push back has been activated, like when wheel slip is detected. Can easily be added to the app good way for new riders to learn if they are hitting pushback and know the signs. could be switched on or off in the app as well.



  • @dustingamble have you tried reaching top speed using this device? I nosedive once I hit 14.7mph.
