Is this "Pushback"?

That's just crazy! I would be shitting my pants while riding :anguished:

I'm so glad someone else said what I was thinking.

That shoebox mechanism is ingenious @Wayne, But it also highlights a pretty conspicuous absence: why can't the one wheel application record your ride speed statistics for you and then show it afterwards in a little graph? Right now I'm using third-party applications meant for bicycling but it's silly to have to do that when the one wheel is always tracking the speed anyway. @Julian, whaddya say? :)

Took a big dive yesterday. Got pretty bruised up. Trying to figure out what happened. I've been getting pretty good and comfortable on the OW and finally switched to Extreme. Was cruising around for a couple miles, thought I had the hang of this thing when, BAM it seems like the thing just stopped. Felt as if the nose of the board just angled right into the ground and down I went. Had 50% battery left, probably at or near max speed, don't remember any pushback. It seems like a glitch. If not, the only logical thing I could think of was that my foot came off the pad but I was cruising doing large sweeping turns. Not enough to release the pad. Has anyone else experienced a sudden stop, glitch or whatever that caused an endo? Lost confidence in the boards electronics now.
The spill looks a lot like the one at the end of this video https://www.youtube.com/watch?v=bT8uX0Ek08c . He's probably in classic and new at it but what did he do wrong? Look like his board just nose dives right into the dirt too.

[TechMSS]

That's a really interesting find, @Jens: From the video, I have no idea why that spill happened. It looks like the board just stopped balancing...

I have found the only time my board nose dives is when my foot is off the sensor. Being always cognizant of that, my incidents have exponentially decreased.

[DocBlock]

If you notice in the video, he lifts the front part of his foot off the sensor right before the board nosedives

[Jens]

Yeah, I looked for that. I see his toe lift but the ball of his foot looks to be planted pretty solid on the Sensor pad. It can't be that easy it disconnect. I found that getting my foot off the pad for dismount was one of the harder things for me to master. I hope your right in any event but I'm not convinced totally yet. Just wanted to see if anyone else had experienced what seemed to be a glitch leading to a dive.

[TechMSS]

Not yet but I'm still in Classic... Have had the board a week, and only got confident enough to experience pushback for the first time today. Was thinking about switching to Extreme, but I may hold off...

@TechMSS Extreme isn't really all that extreme, it is just a bit faster. Find an area you are comfortable riding in, put on your helmet and hop on. Extreme 1.0 used to be EXTREME with extremely snappy, aggressive response. But the latest firmware has smoothed it out, really not a huge difference from classic.

@Jens

To me he had to lift his foot up enough for both sensors to fail otherwise there's no reason for it to happen.

If you've been riding around in Classic no issue, just switched to Extreme mode, did you get too deep into it against the push back? Were you on a hill perhaps? Are you on the latest firmware? Extreme I think babysits you far less basically letting you make your own mistakes. You want to lean more, okay, it'll let you.

There's a good definition and video of how the sensors work below:

https://www.youtube.com/watch?v=BSRbAf7obNQ
The two pads act independently. The board will only engage at level (from a stop) if you are pressuring both pads. However, once you are riding you can come off of one or the other as long as you are traveling at speed. This was designed to allow for riders to life their toe or heel slightly when digging into a deep turn. Once you slow down below about 0.5 mph with one pad pressured the board will disengage. Essentially there is a speed threshold where one pad engaged deactivates the board.

Agreed. Extreme is a very smooth transition from Classic once you feel comfortable. Whether you go fast in extreme or not, the board just feels more fun, and actually a little easier to control.

Thanks for your insight and opinions.
Barring an electronic glitch, which seems unlikely now, the only thing I can think I did wrong was push past into what ever little push back there is in Extreme mode. But what happens in Extreme when you have hit the speed limit? I didn't feel push back, the nose just dove into the pavement. Is it possible that if I was at max speed and I was still leaning forward into it that the board just wouldn't go faster to keep me up and over I went? It seemed too easy for that to happen, if thats what went down. I like Extreme but with out push back I need some warning, audible or pulsating from the motor you can feel in your feet, that I'm at the limit and if I lean forward any more the board won't keep up to keep me up.
Thoughts, experiences?

Looks to me like the video was taken early this year...maybe around CES? At that time they were still on an earlier firmware that I think was cutting power whenever one of the two foot sensors lost pressure regardless of speed. Sounds like a lot of people were initially losing power suddenly because of this which caused more injuries at the time than we are seeing with the current firmware. I know those early backers became more cautious and defensive due to the worry power could shut off accidentally due to lifting off the pressure pads.

Personally I started with firmware 3000 and I've been able to ride all heel or all toe in turns without losing power from the start so I think this issue has been fixed. Safety is now really good and my only concern when riding are potholes or big sidewalk bumps.

I've experienced my first pushback, two others pushbacks at a pretty fast speed, and remedied the problem after contacting customer service. Two days ago I ate it pretty bad (fractured my wrist) because I wasn't able to control the pushback, I did lean back but it won't slow down. Now, how would you (I) know if you're leaning back (enough) or not? I am not discourage to get back on, but I'd like to hear some experience rider to shed some light or at least a video demonstrating the remedy. Thanks in advance.

@CleverMonk Best advice is to never lean, either forward or back. Learn to keep your center of gravity (your body) directly over the wheel and keep your body weight pretty equally distributed across both sides of the wheel. Speeding up should be done just by tilting the board using your legs, not by leaning forward (which leads to bad things).

One way I recently started thinking about it is this: Always be prepared to brake. Meaning, if you're leaning too far in either direction, you won't have the balance needed to instantly tilt the board in the opposite direction if necessary. And if this is the case, you're doing it wrong. Practice suddenly braking while riding until you can do it whenever you need to.

If you experience pushback, just stay calm and level the board (not by leaning back, just by leveling it with your feet) and wait for the board to slow down on its own. Concentrate more on just keeping balanced and steering. If you're properly balanced, the speed shouldn't be an issue. If it is, you shouldn't have been going that fast in the first place, because you're not ready.

Ride slow until you're good enough, then speed up a little at a time. I've been riding 5 months and I only just recently rode it past the point of pushback a couple of weeks ago. I rode slowly through an empty parking lot every day for 3 weeks, practicing stopping, turning, and dismounting & mounting before I started trying to ride faster. It's worth it, trust me.

(And yes, @MichaelW, I did write a long explanation again.)

@CleverMonk
@thegreck told you everything.
And you may listen the board too.Here is an old video I made (I have to do a new and better one about pushback/top speed):
https://youtu.be/2n3jU9-TwV8
Hope the video sound will help you
Plus:a good exemple on how you can avoid nosedive playing with your feets at 3sec. here:

Ok it's fast but you can watch an rewatch in slowmo ;)
Good Luck dude!

@thegreck @fabuz Great advice as usual!
