Nearly Killed a Child

  • Sorry about your clearly defective board, best of luck getting a solid repair. But let me share some long-term experience to emphasize how rare this is: I have 3 onewheels and none has ever become a self-driving missile/deathtrap. I ride with a group of 20+ people every Friday and I've never seen it there either. This is rare, I assure you. I'm not saying that means your experience was safe or fun, I'm not saying nobody else has had this experience ever. But it's also false to say that the machine's design is flawed and dangerous when it has properly functioning sensors. I've seen the proof over several thousands of miles of riding.

  • @Achamian let me know if you change your mind, I can easily fix that issue so it never happens again.

  • @readysetawesome

    I wanted so much to be the guy with your experience. I can shred the ow on the beach. Until the runaway incident my one wheel had been a pure joy. I bought my ow thirty minutes after my first ride on the beach. I didn't even leave the beach the first time i tried it. I sat in my truck and ordered it over the phone. Additionally, had just linked up with a crew and started group riding. I loved the thing.

    I don't know how rare the runaway issue is i just know it happened to me and it was not satisfactory. I am a real safety oriented guy when it comes to other people. I run a swimming program for third grade students, i teach surfing lessons in the summer. I'm a lifeguard instructor. The safety of others is something that i prioritize. If there's just a tiny chance that my one wheel may run away at the rate, velocity and distance that i saw mine then i simply don't want it anymore.

    You can play the statistical game all you want with other peoples lives but i don't want to. I have to be honest with you that it's my direct experience with nearly harming a little kid that led me to this conclusion. I wouldn't wish my experience on anyone. I would really have liked to have been the guy on here telling your story but I'm not.

  • @jeffmccosker

    How can i make sure it doesn't happen again! On your video the guy jumps because he has to bail. Ive considered that if i do a different technique it still doesn't mean i may not have to jump again someday just because of bad terrain. How could you make sure it would never happen again when you just provided a video lesson on how easily it happens

  • @Achamian replace your front footpad. The sensor is malfunctioning. Rare, but it happens.

  • I wouldn't worry about selling someone a defective, dangerous board. It's only the footpad that is defective, and that is a $150 fix. They have been known to malfunction due to water damage, so if you have ridden exclusively on the beach, that is the likely cause. It doesn't have to have been submerged, Onewheels are often not very water resistant at all. It doesn't help that Future Motion has often posted videos of people riding in conditions that void the warranty. While it is fun to ride on the beach, salt water and electronics do not mix.

    The heel lift is also key. Don't step off until the motor has disengaged.

  • @IanJohnson

    Fair enough. I so want to be brought back into the ow party. I have definitely ridden in wetish sand. Not exclusively but I always ride barefoot and my feet sometimes get caked when i portage around bad areas so i figured that might be a problem but one of the guys i ride with has 900 miles on his and never had this problem. Same conditions. If I'm going to fix the foot sensors and get going again is there a further way to safeguard against this issue? Like a way to further increase the water resistance of the deck? The only place i want to ride it is the beach but i have to make sure this can't happen to me again.

  • @Achamian put a leash on it.

  • @nateraso not sure if you’re joking—but that sounds like it could be a good idea. Similar to surf and boogie board leashes. Could result in an uncomfortable pull to the rider if the onewheel starts ghost riding, but if the leash is short enough, it should prevent the board from reaching too high a relative speed to the rider’s body.
    Could certainly cause injury to the rider, but will prevent bystanders from getting hurt. Which I suppose is the lesser of two evils since we’re choosing to ride and the people around us don’t have the same choice.

    A deadman’s leash could be an interesting concept, too. So the board flies off, but the leash is meant to detach with enough force. When doing so, the detatched leash pulls an element that was completing the circuit between the power cells and the motor. This would be a mechanical backup fail-safe solution to the primary software solution that is the deadman’s switch in the front pad that should send a signal to the board to stop.

    This leash/key would also be able to prevent people from riding off with your board as it won’t run without the leash inserted (though I don’t see someone riding off as a primary form of theft—if someone wants your board, they’ll just pick it up and take it)

    Something to still be solved for; a leash could get hung up on something while riding causing another set of concerns/risks. You wouldn’t want to inadvertently cut all power to the board at speed because your leash got hung up and pulled on something. But there is something interesting in this concept. 🤔

  • @eckit I was serious. The key idea is great! Like a wave runner. I was thinking a non coiled leash drilled through the top of your fender. If you get a runaway and bail the motion should cause the board to go sideways and stop.

    I love this idea. I can run after someone carrying my 25lb OneWheel, but I can't catch them if they're riding it! This takes the "key" idea from the other thread one step further. :)

  • @eckit - the first time a bystander gets injured by a runaway board, I think FM is going to have to implement a deadman's leash, or shut down. I think the fact that it also enhances security, so that a thief can't do anything with the board unless they also have the key (which should be attached to your person), is a wonderful bonus.

    I wonder why this wasn't the default design - like @nateraso says, physical-electrical-circuit-interruption deadman leash/key-switches are standard on Waverunners.

  • It does not have to be a physical leash (like a plug or cable), proximity (rfid, magnetic etc) might work better as there is nothing to get tangled up. Say an ankle bracelet or something attached to your shoe.
    The downside is yet another electronic component that might break.

    The most important question then is if such a product would appear, what would be the proper OneWheel fashion response?
    Diamond skull ankle bracelet? Rfid implant in foot? ("OneWheel 4 lyfe!1")


  • I'm pretty sure O/W will never (on the advise of their attorneys) admit any fault of theirs or their board's. Hey, for all they know you could have made up the whole story. I believe it, but since there was no harm, no foul, I think you're over reacting. BTW, I like the leash idea. Even a key switch. I use a bike lock on mine. A friend packs (legally) always. He says a thief might be able to outrun him but they ain't going to outrun a .38 slug - LOL.

  • @speedracer

    I would call shooting someone in the back for a used ow over reacting but whatever

    I learned the heel lift stop. It's for sure the sensor. I'm pointing my toe up like a friggin ballerina and 1/4 of the time the motor wont disengage. I've also been perfecting kicking it on it's side if I'm forced to jump because of the sensor thing. I'm going to try to replace the sensor myself. It looks simple i don't see the point now in sending it off. At this point I've bitched and moaned so much about this to future motion I'm afraid I'll never see my ow again if i send it off.

    I'm thinking about a small surf leash attached to my calf. It would suck in the case of a running bail but i think could pretty safely eliminate my fears of accidental runaway. It feels like the beach has some extra danger with the runaway issue because of the distances the ow can build before smacking an obstacle plus wet sand

    I decided I'm going to keep riding. Thanks for talking me down everyone i was pissed when it happened. I still am. The incident itself was ridiculous. Everyone who owns a ow should want a solution to the runaway issue and everyone should be made well aware of it. I was not aware of how real it could be until it ranaway from me. Now that will awlays my primary consideration when i ride.

  • @jonas - I thought about RFID/proximity type stuff (like a keyfob, for newer cars with pushbutton ignition) - it's just that I'm not sure I trust that to always interact immediately the way it should (or, not to ever accidentally lose connection when you are in motion), when an old-school physical interruption of the electrical circuit is basically foolproof.

    Think about the deadman switch on a lawnmower - never fails, that thing shuts off immediately if you don't hold it.

    Think about connecting a speaker to your phone with a cable, vs. Bluetooth - Bluetooth is better than it was, and it usually works the first or second time now, but a hard-cable connection ALWAYS works, every time, immediately, the first time, and never drops out.

    I spent a few nights when I got my OW just practicing dismounting because it's very important... you were on a beach, try riding in a city. Need to have confidence in staying stationary and dismounting.

    On trails or when you need to bail quick (well, or anytime), you can also slow down and then remove your whole front foot at once and step down with your rear foot. Jeff called this the "no-comply" method above. This is how I keep my board from rolling when I need to bail quickly on trails. If the sensor was stuck it would try to drive the board into your rear foot... which is still better than taking off.

    Glad you've gotten back on the OW. I also ride with a large group and have two boards myself and have never had a sensor issue. Do you leave the OW in a hot car?

  • @skyman88

    No, i think the problem was i was riding backwards. I've mastered the no comply method. Since the runaway incident I've had a few times now where i lift my foot but it won't register and a bail where it did drive back into my leg. ive stopped beach riding alltogether. My one wheel is very well cared for and never been left in a hot car. Shop vac cleaning after every use. The start button and charging port are always covered with duct tape. I hope it's just the sensor and not a larger issue. I'd really hate to go through that again. I've only had to bail a couple of times since the day of horror but my breath catches every time. Ive gotten really good at kicking on it's side as i bail. Even when it began to drive back into my leg on the previously mentioned bail i was able to quickly kick it on it's side to mitigate the danger
