Thrown off after nosedive with no pushback warning (nose dive, nose-dive)

  • I was thrown 1 month 1/2 ago. It was in a classic mode, trying to cross a small pavement, I was not going really fast. I was on concrete so I just dislocated my elbow... I am still recovering. Does anyone have a solution for this ? From what I read, there is no safe mode, and it is NOT a speed issue.

  • As was said on this forum already many times:

    Everybody gets thrown off in their early days.
    A lot of people complain that it was caused by a malfunction of the OW.
    But after gaining some experience it magically doens't happen again (or people admit they were getting cocky when it happened)

  • @Polle What you are saying is pretty accurate.

    In the beginning I got thrown of a few times and blamed on the OW, haha
    Its just the matter of getting used to it and master it.

    After that you will most likely not fall of for random reasons.

  • @kbern I will respectfully echo the past 2 posts. As I tend to do, I pushed the limits and crashed badly due to my own cockiness and over confidence. On a snowboard, it's not usually a big deal. On a OW, the stakes and the pain are much higher. Now that I know my own limits (the OW's limits are probably much higher), I'm able to cruise, enjoy the ride and so far, no random falls or "malfunctions" since.

  • @tomtnt when I watch your dump, it looks like you were trying to accelerate at the same time your board went through a slight depression in the sand causing the nose to dive further.

  • I have had a couple of similar experiences to the ones others have reported:
    classic mode, moderate speed (~5mph), comfortably cruising/carving and then....straight over the falls, trying to run it out, meet the pavement, quick shoulder roll, assess the damage.

    I have done enough board sports for long enough to know when I am pushing it too hard (yep, got a few of those boo boo's too) and when something else is going on. The frustrating part is that its hard to recreate this.

    But, I am working on a theory that I would love feedback on if you have had this issue. Also, I think this idea would explain why this tends to be more of a noob issue. This has only happened to me when traveling at a slow-ish speed (one that a noob would tend to be going). I think what is happening is that, at that speed, hitting a rock, bump, etc is creating just enough deceleration to tip me forward off of the board but that there is not enough forward momentum for the OWs gyros/motor to kick in and accelerate out of it. I think this would explain why as you progress in riding, this tends not to happen (because we tend to ride with just a little more speed). Others agree/disagree?

    PS, before you jump on the "it will get better with practice" bandwagon, I am a comfortable OW rider on many terrains (pavement, fire road, single track, beach, etc) and surface types (mud, wet leaves, hard pack, gravel, wet pavement, etc)...I get it.

  • @ted you mention speed, but too low of speed actually can cause the board to shut off easier since at low speed both sensors need to be pressed to keep the board active while at faster speeds you can lean on one sensor or the other and the board will stay activated.

    I think the fact that the board is mechanical complicates this issue. My wife tried to snowboard but gave up after many many falls. Since snowboards are not mechanical of course the rider is at fault even though the difference between success and failure can be the difference between leaning a little this way vs not and you smack on the ground. Similarly I've found that ow is highly susceptible to falling if you lean forward too much or maybe shift your feet too much. If you are the person doing this it's hard to understand what you are doing wrong but the fact that it is mechanical opens the opportunity to assume the board could be at fault when if it wasn't you would know it was you. The only evidence I have to prove this issue comes down to experience is that the vast majority of riders have experienced being thrown and not understanding why but after much experience it rarely happens even with the same board. What changed? If you are an experienced ow rider and it is still happening to you then I suggest you contact support because maybe you have some rare defective board that shuts down while the sensors are pressed and without the nose touching down.

    If you look at my post history you see I'm not trying to tow some company line. I've just been riding for 7-8 months and this is what I think I've learned.

  • @Franky I think we are saying the same thing. My point is that this issue is not a mechanical problem but a result of the limits of the torque/acceleration of the OW at low speeds (not a sensor issue which would be triggered only at very slow speeds: <0.5mph).

    Both sensors only need to be activated below 0.5 mph which is way below the speed at which I have experienced going over the front. However, when I have pitched forward, I can find a specific reason for the deceleration (rock, bump, etc.). I think that as I hit those, my weight pitched forward (Newton' first law) just past a critical point at which the OW torque/acceleration caught up with me.

  • @Franky if you accelerate too fast, You will nosedive. You will not feel a pushback cause you are pushing through it too fast. The cpu thinks really fast, but it's not a super processor. Just feel the accelerometer build speed gradually not immediately.

  • I nosedived 4 times during my usual commute today.

    I wasn't doing anything crazy -- just riding straight in extreme mode (about 8 - 10 mph) on perfectly smooth pavement. However, i did feel less pushback than normal which made the board feel a little unstable.

    After each nosedive, the board completely turned off. When I turned it back on, it flashed normally (no errors). Strangely, when I checked the OneWheel app, it had been set back to classic mode.

    I contacted support, and I'm sending the board back to FM tomorrow. I will post an update if I find out what the problem was.

  • @danny I can see how Classic mode would do that, since it maxes out at a much lower speed. So if the board had somehow been put into that mode on accident (I think there's some series of pushes of the power button that can do that, if I'm not mistaken), you could have those issues.

  • @thegreck It could have been by accident, or somebody could have done it as a prank because the app doesn't have any security yet :(

  • @thegreck I thought the same thing too. I noticed that it was in classic mode after the 3rd fall, and set it into extreme mode immediately before I started riding. After the 4th nosedive, the board turned off again and was back in classic mode.

    Even if it did somehow switch to classic mode while I was riding, it should still give me pushback at 8 mph.

  • @danny That's scary. Yeah seems like a malfunction.

  • Wanna share with you about my tail dive(not sure it's the good word)...It happens sometimes(less now with experience) only on my backside turn :disappointed:
    Sensor Foot pressure and placement seems to be very important :smirk:

  • @fabuz glad you were able to run it out! What is shown in that video is not what happens to most people with a nose dive and needs it's own analysis.

    A nose dive happens when your center of gravity is either mostly balanced or towards the nose and you either come off the sensor or touch the nose down trying to go too fast.

    A tail dive happens when your center of gravity is mostly on the tail and you come off or let pressure off the sensor such as might happen if you touch the tail down and lift up or shift your nose foot.

    I have tail dived several times when riding off road down a steep incline with some big in ground rocks. When approaching a rock I'd try to slowdown quickly ending in a tail slide, pressure coming off sensor, wheel locking up, and board shooting out from under me as I fall backwards. After I did that a couple times I started taking this hill much slower to maintain control which worked well.

  • I've had the OW for a few months, love the thing, but there is definitely something going on with nosedives in extreme mode. I've had it happen and ate San Francisco Asphalt more then once, at least three times. Same deal with what has been described on this thread - extreme mode, 50+% power, usually flat, then out of no-where the front hits and I go flying.

    OW devs: We should have the ability to record all the readings (accel, speed, etc) as sort of a flight recorder of data. I'm sure a lot of us would even send it to OW to analyze. There is something going on here, and if you'd just give us the tools - SDK? - we could figure out what's going on from the data.

  • @fabuz I may be wrong, but after watching the video, it looks like you had a pretty heavy pushback and your tail touch and you foot came off sensor all in a second. I've had my tail touch a few times. I found it helpful to practice in a controlled area recovering from a tail touch.

  • @TonyGDTLA when do tailtouches occur? whenever you get a heavy pushback? or how were you able to practice them? :D

  • @chabis sometimes the pushback pushes and without thinking your center of gravity could shift back. And if you lean back in too fast it the tail will touch. I would practice on grass (helmet and stuff) accelerate fast then hard break. Tail will touch and drag. But stay balance and try to recover.
