    V8 tire pressure

    As suggested by another forum member, I adjust the pressure to get the most neutral turning behavior of the wheel. For me it's somewhere between 35 and 40PSI, I believe closer to 35 than to 40. This fits quite precisely into the above linked appropriate pressures graph from ewheels.

    Red and Orange Battery lights on Glide 3

    Agreed that each bar marks (about) 20% capacity. To my experience going from 2 bars to a 1 bar yet seems to take a little bit longer than for the other bars.

    HELP! Strange noise in my V8

    I'd like to see a (first) picture of a bent or broken axle of a V8 or V10 before to make any premature conclusions.

    Software speed limit consequences?

    For riding into a wall my hunch is that it wouldn't matter anyways.

    Help me choose my first EUC

    Have unintentionally lifted a powered on EUC many times and many people that I have let try have done it despite my warnings (some literally 2 seconds after I told them not to). It's quite unintuitive to grasp that one should not lift it even for a short moment. We are all humans, while you must be super-human, clearly.

    Help me choose my first EUC

    Yes, as with most EUCs. It will turn off when it has reached its maximal (spinning) speed and it cannot be recommended (at all) to put it on the floor (or foot) before that has happened. If you are talented you may be able to slow it down by doing controlled forth-and-back swivels (I can only do it with one of my wheels and not quite reliably).

    Software speed limit consequences?

    15% more impact on your bones to crack in exchange to 7% of increased speed or saved time. At this speed, 15% is IMHO already pretty significant.

    Software speed limit consequences?

    What's the point to squeeze out 2km/h when you expect to fully ride into the tiltback anyway? The concern I have is neither motor problems nor overheat but riding closer to the torque limits and at higher speeds, which increases the likelihood and the severity of a crash.

    HELP! Strange noise in my V8

    Doesn't sound to me like a bearing problem. Indeed, first I would check whether the valve is touching something.
  10. The InMotion V10 is improved over the V8 in almost every aspect as described in this review, and I am excited to try out the wheel soon! Apart from the obvious (power, range,...) I highly appreciate the notably improved pedal ground clearance, the slim shape and the wider tire. Yet, two specification parameters have become notably worse. The weight went up by 7kg from 13.5kg to 20.6kg and the overall wheel size increased notably by 8.5cm in height and 7cm in length (the width increased by only 1cm, which is highly appreciated). (source) These specifications attract users towards the high-end range: those who went in the past for the Msuper instead of the V8. But will they also attract the "mass market", the millions of not-yet EUCers, those users who went for the V8 instead of the Msuper in the past? I have my doubts and I couldn't recommend it to the potential newcomers I know of. Personally, I may still buy the V10, but I am also desperately waiting for a wheel which supersedes the V8 in all its specifications, or at least doesn't fall behind. This is certainly much more challenging to develop (more power, more range, larger pedals, better light, a USB port, a wider tire and yet lighter and not larger), but this is where technological improvements should take us.
  11. The safety feature of tilt-back is that it strongly incentivizes the rider to slow down, because it is hard (up to impossible, depending on the angle) to keep the feet in the backwards tilt position which is necessary to maintain the speed under tilt-back (leveling the pedals will bring the wheel in front of the rider and thus inevitably initiate a slowdown). If you have changed the base angle such that the tilt-back angle is horizontal you have turned off the mechanism by which tilt-back makes riding the wheel safer. For your safety remains that the change in pedal tilt signals that the wheel has reached the limit speed. The strong incentive to slow down has disappeared. If you ride your wheel at tilt-back speed on level "with more control" you ride it in a constant over-speed situation. I am not quite convinced that this is what I could call uncompromised safety.
  12. To prevent falling left or right like in this clip, you have to turn/twist the wheel in the direction where you are falling. Just tilting the wheel to the side as you did is not enough. It should be very helpful to practice these swivel movements as described here

    Ninebot One Z8 Open-β Tester's FAQ (link)

    "a lot" means twice the current on a 40V system compared to an 80V system. Sure, you need to lessen resistance where it matters, but that isn't really rocket science. I am absolutely positive that Justin has heard about this problem and the solutions, even if he hadn't been talking about it 😀, though I actually hear him talking about it in this very vid at around 7:20.

    Ninebot One Z8 Open-β Tester's FAQ (link)

    I guess that is true all else being equal, which is not a very reasonable assumption to make for two systems designed to operate under two different base voltages. The "problem" remains that the e-motor engineer Justin Lemire-Elmore owning Grin Technologies tells us very elaborately that voltage has essentially nothing to do with e-motor performance. Is he wrong? https://youtu.be/IxB2j-egWcQ?t=5m33s

    Ninebot One Z8 Open-β Tester's FAQ (link)

    My hunch would be that this is because higher voltages do not give any decisive technical advantage, apart from the publicity buzz. The additional wire weight is probably rather insignificant overall.

    The future is not 30 mph EUCs

    Most people don't believe that. Surprising even "only" 30% of the below poll responders are of the (totally crazy ;-) opinion that EUCs which can be driven without license or insurance should have no legal speed limit. Some related topics:

    Uniwheel out of buisness ?

    BTW, what was the outcome of your test ride? I am seriously considering to check out the Uniwheel, but if e-roue can't organize a spare battery, I most likely will not buy it. To have at least one extra battery seems to be a must for this wheel.

    The future is not 30 mph EUCs

    This would ban EUCs from being legally operated on sidewalks in many countries. This would not be my favorite legislation spot. There is a good case to be made that EUCs mix better with pedestrians than bicycles do already due to the space requirements. I'd personally prefer to be banned from streets over being banned from sidewalks. Banning them from sidewalks would also significantly impede popularization, IMHO.

    New Design for Balancing Electric Unicycle

    Yes, though to a lesser extend as transportation device with speeds of more than 10km/h. I also like this application:

    how to stop pedal scraping????

    Isn't the real question why stop pedal scraping? I can't possibly see anything wrong with it. Scrape away, man.

    German Discussion Group

    Yeps, irgendwie inoffiziell legal. Nur in manchen Parks und auf U- oder S-Bahnsteigen wurde ich schon unmissverständlich gebeten abzusteigen.
  23. How much is safety worth to you? At least €2000 per year to me. How do I compute this? About 1h of safety training per week makes, putting a low hourly rate of €20, 52*€20 ≈ €1000 per year. Then, I lose about 8 min per day because my average speed is 20km/h instead of 25km/h, which is another 50 hours per year, so another €1000. I think it's worthwhile and has a higher return on investment then putting the money in material, but mileages vary.

    Braking/Stopping Practice

    They should have more power to brake than to accelerate, because the back EMV is a tension that works against the direction of spinning.
