After a failed dismount, my onewheel took off!!

  • Holy smokes!! So two days in and I suck at dismounting. In fact the only times I've fallen now have been getting off. Tonight I decide to try the night aspect and see the lights (INCREDIBLE) and I go to get off, and I lose my balance as I'm stopping. I'm basically stopped and I fall back and to my left (towards the foot sensor side) and I fall on my butt and the board takes off like full speed GO. Actually put skip/skid marks in the tire from it bouncing and shooting off. Thank goodness for a light fence to stop it. It travelled about 15 feet full throttle before it stopped. Almost like the foot sensor didn't know I was off? Scared the snot out of me. Still love it ;) xoxo

  • Sorry to hear about the failed dismount, I am 2 weeks in as well. I have found the best practice for dismounting is to find an area to roll a few feet stop, balance for several seconds, roll a bit and repeat several times. As your confidence builds with your sustained balanced stops, rotating your toe off the sensor will allow you to slowly and controlled set down of the rear skid plate. I was out in public last night with more curious people than usual with lots of questions. My practice definitely payed off as it allowed me to stop and balance and chat or seamlessly dismount for longer stops. We rolled to dinner last evening, wife and daughter on their Solowheels and had a blast image.jpg

  • @Docblock has it right. I don't get off anymore till my board stops. I will keep lifting my foot till the thing stops on me then I dismount. Its challenging but after a few near mishaps I am much better at it now.

  • I've never had the board continue more than a second after falling off. I think the latest firmware does not cut power as quickly as v1 firmware when sensor pressure is lost which probably helps a lot. But this sounds like a pressure pad glitch since the firmware would have shut the board down quickly if it new there wasn't pressure on the pad.

  • you're not the first to have this happen; it really worries me

    mine got hot in the sun while i was out playing volleyball and the glue under the grip tape heated up

    when i rode it and hopped off to dismount it shot off and only stopped when it hit a tree

    i adjusted the grip tape and it hasn't had the same problem since, still scares me everytime i dismount i think it'll be the time it shoots off again

  • I recommend doing a controlled dismount: rotate your front foot off the sensor while staying balanced. Wait for the board to shut down, then ease your back foot to the ground. I have never had an issue with that process, despite significantly rotated grip tape and leaving the board out in the direct sun for hours.

  • The instructions talk about gently lifting the foot off, I hadn't thought of rotating the foot and will definitely try it. Thanks for the advice!

    My last failed dismount (due to being caught off guard going down hill) caused some pain, but more for reason of mixing up which was the control foot. To the Future Motion wizards readin this - high contrast, please!

  • Another suggestion - always, always, always place your front foot on the sensor. That way it becomes muscle memory as to which foot controls the sensor.

  • @lynnpreston ..what you suggest seems so obvious, the writing on the board, it's orientation as it stands, the fact that you need the control pad to put the thing in motion... are all giveaways. But until the muscle memory is there, the chance that you mistake which foot to take off puts new riders at risk. This is the same as car drivers mixing up pedals - which apparently in the US alone leads to 16000 "preventable crashes" a year!

  • @loleg - Agreed. However, I have conversed with several new users who ask if it matters which foot they place on the sensor. My emphatic answer is of course "yes".

    Related - I wonder how many crashes are caused by people switching from manual transmissions to automatics. Whenever I drive my wife's car (automatic), I invariably start hunting for the clutch with my left foot and accidentally jab the brake - throwing everyone forward into their seatbelt :blush:

  • @NuclearDeLorean I had this same problem! In fact it was doing this all the time after it started. I was getting used to jumping off and grabbing the board at the same time so that it didn't get away. I then started rolling my foot on the sensor up on its side, and the board would shut off after a second without issues. I still wanted it to shut off like its supposed too. I was worried that if I fell off, it would leave me, and maybe take off into traffic, or worse in a lake. Once I peeled back the grip tape over the sensor, I repositioned it and ran some pan head screws through the tape and nylon strips, it hasn't done it since. If you are interested I can post a pic of the repair.

  • So much better now. First, I always have my front foot on the sensor. Always. Goofy is away from the sensor. My board hasn't done the takeoff-!freedom!-move since that day, but I always think of it. Scared the $#!+ out of me.

    My dismounts have gotten better! Instead of twisting my foot off the sensor, after rolling to a slow stop I shift my balance more to my non-sensor foot. I then lift the heel of my sensor foot so 70% of my foot is off the sensor. I wait the one second for the board to shut down and it rocks to standby.

    I'm getting better by the day.

  • @NuclearDeLorean yep took a little bit to get the dismount down but after you get it you are good to go. Still sometimes on rare occasions I'll try lifting my foot off and it won't shut down but I'll be losing my balance. Best thing to do is get balance back and then try again.

  • Exactly. I try to stop and actually go back and forth first to center myself, then my dismount procedure. So far so good!

  • Just saw this. I've fallen off tons of times especially trying to do tricks like this and this never happened to me. board shoots off without rider

  • [sorry for the cross-post]

    Guys, this thread wasn't started about how to dismount smoothly. It was started by someone saying their board zooms off after a jump-off dismount. That is frickin' crazy dangerous, especially if one is riding in, say, San Francisco, where the board can shoot out in front of a car and cause an accident, hit a pedestrian, or just simply get run over. Knowing how to dismount smoothly (which I do) does not solve this problem because there might always be a time when one has to jump off, and having your board zoom off at top speed (from a standstill) is simply not cool.

    @NuclearDeLorean So, I have experienced the same issue as you, when the board continues to run after I jump off. This seems like a seriously dangerous design flaw. I have written onewheel, but wanted to post here as well for others to find this. I will post whatever resolution I get back from them.

    I’ve had my onewheel out a few times now. I’ve never had a problem with it when getting off of it… I normally get of smoothly by rotating my toe, but even if I jump off it with both feet, that works fine.

    Today, however, I was letting a bunch of friends at work try it (they all loved it, ob-v), they where all pretty much jumping off, and everything was fine at first. After about 45min of this, when people would jump off (from an absolute complete standstill), the board would start running off on its own, accelerating! It smashed under two cars this way, two separate times. Then I tried jumping of as a test, being careful to really jump with both feet at once, and it did the same thing (though that time it only rolled a bit and then stopped).

    This has never happened before, and I’m scared to ride it in San Francisco now because if I have to jump off I don’t want it zooming out into the middle of the street under a car!

    When I get off smoothly, but rotating my toe, everything works as usual, but that is NOT a solution, as I might need to jump off (especially dangerous if I have to jump off in a crowd or in traffic).

    My tape is not slipping at all, as the board has only ever seen two short days of use.

    I just installed software version 3034 this morning. I wonder if there's a bug in that? Though, keep in mind that this runaway board issue was not happening at the beginning of our outdoor session, it only started happening after a while.

  • @kbern - how long would you say the board was accelerating after contact was completely lost with the sensor pad?

    Firmware 3000 and above (AFAIK) has a built-in delay between sensor disengagement and board shutdown. This was added at the request of the early adopters to reduce the likelihood of a very brief sensor disengagement (e.g. hitting a bump) causing the board to shutdown and nosedive.

    Just conjecture here, but I'm wondering if in an uncontrolled dismount where the last "input" the board received was to accelerate in a direction due to angle, the board will continues responding to that last input during the built-in delay. This seems to explain why jumping off from completely level does not invoke the unexpected behavior, but jumping off while the board is at odd angles does.

    If that's the case, it's a sticky problem to solve. The sensor delay can be both good and bad.

  • @lynnpreston Thanks for the feedback. So, I don't recall the version I was previously on (though I'm pretty sure it was well over 3000), but remember... this was not happening at the beginning of the session (which had 3034 on it too).
    Also, we weren't always jumping off at an angle, sometimes it was straight off.
    The "memory" idea is a good one, but I just got home and tried it again in my garage... I got on the board, didn't ride at all, jumped off (being careful to jump with both feet) and it took off... not as far or as fast, about 3', but still.
    I can understand people not wanting a brief sensor disengagement... I was worried about that too if I where to readjust my foot or raise the pressure on my toe while riding, but this situation is pretty crazy. Plus, the board knows it's not perfectly straight anymore (with the smoothest of jump-offs, the board tilts back on the heelside), which the gyro could detect and, combined with no sensor pressure, it could decide that this might be a good time to shut off the board.

    Anyway, this all worked fine earlier in the session, so I'm feeling like it's just a bad sensor?

  • @kbern - Well there goes my idea :-) I defer to @Future-Motion on this one.

  • Yeah, this is a real problem that most have never experienced...especially people who received their boards at least a month ago or before. My reply above originally linked to a YouTube video showing this happen to Casey neistat. My reply is still above but my link was removed by support. What the video shows is not that extra second of engagement but rather the board almost stopped taking off without rider for many seconds before stopping.

    Since this has only happened by people who recently received boards it either has to be bad hardware or a firmware glitch in a tweaked version of 3000. I'm assuming future motion knows what it is and I'm guessing it's firmware because they are more optimistic now about production times and there are these new firmware updates which may just be setting everyone with a newer release back to 3000 before the bug started.

    One thing is for sure, I would not ride a board that has this issue around people, cars, or buildings until it is officially resolved by future motion.
