  1. I thought I'd update this. I was able to get it to be level most of the time, but only with the adjustment set to -5.0. It was rideable but I still wasn't happy with it having to be set all the way to -5.0 just to be level. And some days it would reset back to leaning forward again for no apparent reason and I'd have to fiddle with it to get it level again. I ended up selling it for quite a low price and I explained the problem to the new owner. It was a fun machine but I didn't use it much after I got my second EUC. My thanks goes to Jojo for trying to help me via PM.
  2. It's currently sitting upright, almost perfectly level, but not quite. And I was able to ride it normally, without my toes pointing down, but I have the adjustment set to -5.0 in order to get it like this. If I set it to default it's leaning too far forward. I don't know why some days it leans farther forward upon power up than other days. I wondered if it was interference affecting the gyro. The room I keep it in and have been powering it on in has a lot of electric gear, solar panel charge controllers, large lead acid batteries and audio equipment. But this seems unlikely to me. When the issue presents itself and I turn it off and take it outside and power it on, the problem is still there. Equally, on days when it's not leaning as far forward and can be corrected in the app, it stays good no matter where I power it on.
  3. It's not in go cart mode, no. The problem started by itself. One day I turned it on and there it was. It stayed that way for several weeks. Oddly, another time I turned it on it was not leaning as far forward. With the level set to tilt back at -5.0 (the max it will allow) it was almost level and comfortably ride-able. Then some weeks later it went back to leaning too far forward, even with the adjustment set to -5.0. Last night I turned it on and it was again not quite as far forward. So it switches between 'so far forward that even compensating with -5.0 will not level it out', and 'still forward but not so much that the compensation tool can't level it'. I have dismantled the device and checked that the main board and all other parts are secure. And I have tried the upside-down reset trick many times with no effect on anything at all. I appreciate any help anyone can give as I have not found a single mention of this issue online. Ninebot/Segway customer service simply do not respond.
  4. Thanks for sharing your experience. I don't think we are experiencing the same problem, though. My wheels are not slipping at the axles. It's just that my Minipro tilts forward when resting. Like in this image: If it was just the axles slipping under load the Segway's gyro would still be able to keep the device level when standing by itself because the gyro would detect that it wasn't level and tell the motors to turn until it was level. Mine leans forward all the time. It can still be ridden (but my feet are pointing down all the time) and it accelerates and brakes with great strength as normal and nothing slips, but it thinks the foot pads are parallel to the ground when they are not.
  5. I see the following trick being suggested for all sorts of issues: 1.Turn the Segway minipro/mini upside down 2.Hold the power button in. 3.The wheels perform alternating 1/4 turns and the lights flash 4.Power off. What does this actually do? On my minipro it does nothing. It does not re-calibrate the balance sensor. It does not perform a factory reset. So what is really going on when this procedure is performed?
  6. It looks like I'm the only one then. Just to update, I never did find a solution. I used the adjustment tool in the app to lean it back to -5.0 which got it closer to level and rideable, but not quite level and far from ideal. I have now given up and have listed it in the for sale section. If anyone wants a spare battery that's low mileage (the highest watt hour version) or other parts it may interest you.
  7. I powered on my Minipro today to find that it leans forward at an extreme angle, all the time. It seems to think it’s level. I tried the posture recalibration but that only calibrates the steering, so was no help. And I tried the ‘power on while inverted’ trick and it had no effect. I vaguely remember the early IOS app offered a tilt re-calibration tool which is no longer present. When I add steering input the vehicle levels out, but when going straight it rapidly resumes a fully tilted forward attitude and is unrideable. Has anyone had this issue or am I the lucky first person to discover it?
  8. I know I'm late to this thread but I wanted to welcome Jimmy to the EUC community. I have been watching your OW vids for about 6 months - Slydog's too. And I enjoy them. It's great to see you try out the EUC life. I rode electric skateboards for about a decade, from the early days when they were lead acid powered, heavy beasts that broke down every few months, to later lithium powered sleek machines. I worked with one of the leading electric skateboard brands for a few years. I was there when the first carbon fibre boards were being developed with batteries built into the decks - such exciting times. Then I discovered the joy of self balancing vehicles. And yet oddly, the One Wheel never appealed to me at all. Only when I found your vids and Sly's vids last year did I begin to see them as something that might actually be a lot of fun and something that might give me a more realistic 'snowboard on land' experience than the electric longboards. Before seeing those vids I thought One Wheels were kinda silly and didn't realise they had such a dedicated following. I think I just didn't understand the concept properly and so I ignored them. Now I would consider buying one some day if they refine them a bit and maybe make them a bit lighter and more compact. Like a Pint with more power and range. However, I am seeing them cut out more often than EUCs and that makes me nervous (as if I wasn't nervous enough doing 30kph on an EUC already). Maybe it's just my perception but I feel like I have seen a lot more over-lean cut-outs on the OWs than on the EUCs. In my mind, mechanically speaking it makes sense as with feet out that far from the motor's axis of rotation there is more leverage, so the motor has to work a lot harder to keep you up when you put some serious weight on the edge of the board. On an EUC you're directly above the axis of rotation. I absolutely love the feeling of riding my EUC - when I carve, it feels a bit like skiing without effort. But when I watch you and Sly carving around I feel like that would feel even more fun - like snowboarding (which I find a lot more fun than skiing). Also, I imagine it feels a bit like riding a hoverboard ('Back to the future' style) and may fulfil my fantasy of that. I haven't read the whole thread but I imagine you got a few "EUCs are better than OneWheels" comments, which on an EUC forum is to be expected. You know, like the iPhone versus Android thing. I am thinking personally, having one of each would be the ideal setup. EUCs for range, portability, easier to physically carry or trolley around in places where we can't ride them) and perhaps a bit less likely to cut out. Then the One Wheel for a greater thrill of riding (for those who like snowboarding and longboarding). I'm sorry to know that Sly hurt himself. I fear the same thing happening to me some day. The way he rides through busy traffic is a thrill to watch but I worry for him and fear he'll get some permanent injuries or worse. It's not so much his skill I worry about (as he is good at this!) but the technology cutting out and getting him killed. He takes a lot of risks out on the road with busses and cars all around him. I think at his age he doesn't have the wisdom to see how dangerous that is on a self balancing device that can cut out without warning and throw him under a moving SUV. When I was his age I was popping wheelies on superbikes, racing dirtbikes and landing 12 foot power kiting jumps. But I learned that bones can break and some of them can hurt for the rest of your life. When I think of all the risks I took when I was in my early 20s it's almost a fluke that I'm still alive and able to walk. Now I take much fewer risks. I have been saying on this forum since 2017 that we need better failsafe technology in these machines so we can start to (almost) rule out the possibility of software bugs or electrical failures ending our lives without warning.
  9. I do love a nice, minimalistic e-bike. That's a particularly nice example of one. I converted a mountain bike and a street cruiser to electric a few years ago. But they were far from being 'throw them in the back of the car beside the groceries' devices. Yes, the tiny size and weight of EUCs make them so practical, considering how far they can take us, and how quickly. I have not yet had a fall. I guess I have been lucky, after riding these self balancing things for 2 years as my most often used form of transport in my locale. My EUC has enabled me to cut down how often I use the car quite dramatically in the warmer months. But damn, one battery failure, mosfet failure or software bug could put me in a wheelchair for the rest of my life. There must be a way to prevent this. I remain hopeful that one of us, or someone much smarter can think up a solution within 5 years. I feel like I'm on a ticking time bomb when I ride at any speed greater than a light jog. I see plenty of people on this forum wreck themselves and I'm hoping not to add to the statistics. Now that I have upgraded my wheel to 30kph and often ride at around 25kph, I know a cut out is going to hurt a lot and may leave me unable to do a lot of important things I need to do.
  10. That's one of them. There was another where we discussed having a little wheel in front. I think I photoshopped a concept. If I find that thread I'll link it.
  11. A year ago, or maybe longer, I started a thread in which we discussed redundancy ideas, ie. mechanical or electrical devices that could keep us upright in the event of a power system failure. Nothing really practical was determined. Today I see EUCs are being built to be increasingly larger, increasingly faster and to have much more range. Many of you ride on public roads in and out of traffic. But I still don't see any evidence that the face-plant risk has been addressed by way of a failsafe mechanism. We are still at the mercy of the onboard computer, batteries and electrical components on every ride, trusting and hoping that one of the scores of components won't fail. I think in time, every wheel will eventually fail and cut out unexpectedly. I enjoyed a decade of electric skateboard riding without an electrical failure causing me injury because 4 wheels provide exceptional protection in the event of a power failure and the board just comes to a stop. EUCs are so much more enjoyable, comfortable and practical as a mode of transport for me. But the constant fear of it cutting out makes me feel that in a few years I will probably retire from EUCs before I acquire some permanent injuries or death when the power system fails, unless the safety can be improved in that time. I know some of you work in the EUC business and some of you are engineers that work in somewhat related fields. The OneWheel has a couple of options that help slightly in the event of a cut-out, such as 'Fangs' or additional wheels/sliders out in front that at least give the rider a chance to stay upright when the power goes, until they can jump off safely. Is there any progress being made at finding a fail safe solution for EUCs?
  12. I agree with much of what you wrote. No matter what vehicle, tool, device we are talking about, there are always a minority of stupid people that will use it inappropriately and hurt themselves. This does not mean we should ban EUCs, cars and butter knives. It doesn't mean we should not look for ways to improve our wheels or get the most out of them by doing things like removing software performance limitations after careful analysis and testing. Alcohol kills and hurts a shocking number of people every day and is guaranteed to damage the human body with every sip and yet it is not banned. If we look at the statistics and understand just how destructive it is, it would make more sense for alcohol to be banned before EUCs. If we look at how many people ride EUCS and what percentage of them have died as a result, it is very low (perhaps 0%). If we look at what percentage of them have had their health, relationships or lives irreparably damaged by EUCs it is also very low. Alcohol is good for social settings for those who cannot enjoy life without having their central nervous systems chemically supressed, but it's a carcinogen, it damages human tissue, is addictive, increases road accidents, violence, depression, aggression, career damage, relationship problems etc. But we are free to guzzle it by the litre and let society deal with the destruction. The UK and other countries moving towards banning this kind of personal transport, including electric kick scooters, skateboards and such things is such an odd decision that could only come from politicians and civilians who have little understanding or experience of this mode of transport. The data contradicts this decision. Sadly, many things that are banned in society are banned by the same clueless people.
  13. Have you seen any examples of this issue you are concerned about? If you have, please share as the more data we have on this the better. I haven't yet heard of any crashes caused by this speed hack. I have put a lot of kilometers on mine since the mod and I'm happy to report no incidents, bugs or failures so far. If you live in London, from my understanding EUCs are already pretty much banned there anyway.
