  1. I am the ORIGINAL OP (Rider222), and yesterday, after all these years, my wife's BLACK minipro hit a small pot hole on the sidewalk, and her minipro twisted right, causing her body to twist, and she fell forward and got hurt. Luckily just bruises and scrapes. This minipro then kept spinning in circles, right. She was riding behind me so I didn't see it happen. I reset her minipro and then I took over and kept driving that unit over the same pot hole, and after a few tries, I was able to repeat that event; it threw me off forward and it kept spinning in place, exactly the same. This pot
  2. What you are describing is VERY different than the issues described in my original post. Your issue isn't the very rare intermittent exceeding dangerous issue I was having. Your unit is showing itself to not be functioning properly. Obviously something has broken on your unit; maybe the factory can help get your unit fixed
  3. Sounds like you have the opposite "left" veering variation, which is probably somehow highly related to my "right" veering problem. Or, is your left wheel actually locked up? Anyhow, I have no answers, my errant machine is still in pieces, retired. My new unit hasn't yet malfunctioned, but we aren't riding them as much lately either. Problem only happens when you least expect it. Wear HELMET and be safer.
  4. So in your case, did your Minipro always have noticeably odd issues, or, does it seem to be getting worse over time? Did your issues only become noticeable after a firmware upgrade? What I'm asking is if a "logical" change (programming) could be causing your issue, or, is some component is gradually (or instantly) failing. I feel MY Minipro probably always had this issue, firmware upgrades over time, didn't change anything. Again; MY "veering right" issue happened extremely rarely, and, possibly (see my original post) very early on. And, MY veering issue was ALWAYS extreme; instant 9
  5. When the problem happened to me, my gut feeling was that either it was an "edge case" algorithmic problem, or, more likely an actual physically bad component/connection/trace. When the unit has acted up, there was always a vibration/bump involved, but always your normal fairly common minimal bump. I typically ride (hundreds of hours of experience) over extremely bumpy off roading/dirt/gravel roads with no sign of any problem. So having this errant Minipro randomly veer right, while riding full speed on an otherwise common smooth sidewalk with the vibrations only being somewhat normal expans
  6. I'm glad other people are locating this thread, and discussing this issue. The first time the veering happened to me (per my OP above), I was going full speed straight on my hard dirt/gravel driveway. Something I had done hundreds of times previous to this accident, and many hundred times since. I had never even came close to losing control at any other time. Sure, off-roading, you always feel a bit of highly controllable slippage, corrections, etc. But from going to 99.999% of the time feeling safe being in complete control, to 0.001% of the time to absolute complete uncontrollable veerin
  7. I certainly kept wondering at first if the veering problem was caused by an edge case, sensor/algorithm issue, but as it only happened with that one Minipro unit (so far), and have not yet experienced with either of my other two Minipro's; I'm pretty sure that one errant Minipro was (or became) defective. I'm hyper sensitive to the issue, so if I ever feel that again (or any oddity no matter how small) I will not ignore it. I'm not talking of course about normal/odd algorithm concerning wheel slippage on unstable sand, or rocks.
  8. Please wear helmets. I guarantee you will NEVER have an accident; that is, until you do. I will never again ride any segway without a helmet. A good analogy to give you to relate concerning this veering issue: If you are driving your car down a road, or freeway, and instantly your steering wheel (and all controls) randomly disconnect, and your car makes an abrupt hard right turn... Very scary.
  9. What Zephyrzone is describing, is exactly how I would describe the issue. The difference, in my case, the issue was extremely intermittant, making it impossible for me to repeat/track down. In YOUR case, the problem is showing itself much more repeatable, so you might actually have a chance to locate the problem. It's a very eerie and gut wrenching feeling to have this otherwise stable unit, randomly veer out from under you. You can't ride what you can't trust.
  10. The solder joints look perfect. I'm very good at electronics, and have much experience with lead tracing, board inspections, etc. My concern is even if I re-solder, I just can't trust my life on that one, since I can't be certain problem got fixed. If I can't actually trace down the problem, then I can't consider it fixed. My gut feeling is there is problem of a glitch with the steering sensor circuit. I may eventually replace that whole circuit and try again. Also I've taken it apart so many times, I've broken a connector pin off the main board to the tail light assembly; that's when I
  11. I appreciate the reply and will of course look into it, but this doesn't "feel" right to me as being the problem. I often practice riding on just one foot, and then the other foot, so I know what exactly "normal" feels like. I'm basically an expert at riding on/off road (forward and backwards) so I know normal. Doesn't make sense to me that the foot sensors would cause an emergency/immediate 90deg veering to the right. As you can imagine, a random unplanned 90deg turn while cruising straight 10mph can only end up in disaster. Worse part is at such an abrupt turn while going fast, your b
  12. I've seen [only] one old thread kind of discussing this, without satisfaction, so thought I would start up a new thread, as I can't be the only one with this safety issue. Bought my white Mini-pro brand new about 6 months ago off Amazon. Actually bought two, the black Mini-pro isn't showing any signs of problems. After the first couple weeks of running the one in question, on dirt/gravel road of being 100% stable, while driving straight, the Minipro made a quick right turn (veering right) throwing me forward off, twisting me (right), landing on my back, banging my head, knocking me
