  1. You don't need the KS app to ride; unless you need a recalibration then why bother using it? As for speed wobbles and riding fast with others, it's my recommendation that you simply need more quality hours with your wheel. Quality hours does not mean cruising on the street with 90 degree turns, but instead a decidedly more challenging environment. Find a park path or even a parking lot that you can fake a path, and use it like a tiny go kart path, and go round and round many times. Many many times, where you'll come back to the same spots within a short period of time. Within 20 minutes to two hours you'll get some idea of how you would like your wheel to handle, and now you can play with your tire pressure so it handles better. Then, when you're comfortable, do the second thing with a rougher path, dirt or gravel perhaps, with roots and jumps. Perhaps cobblestone. 400 km is a lot if they are quality KMS, but, conversely, if you're cruising on the flats with no turns, it's not a lot. Those traffic cones or poles you see...they are placed there for you to slalom around as fast as you can, as often as you can, forwards and backwards.

    Can everyone learn to ride an EUC?

    There's too few points of contact to make riding the seatless EUC particularly easy, but the seated EUC with a handlebar which allows you to "paddle" your feet on the ground should allow you to learn sweat-free, without the drama of constantly stooping to pick up the wheel. In my opinion, EUC manufacturers would do well to add the seat and the handlebar as training aids, because the steep learning curve of EUC comes from mounting the wheel and also relearning to use your legs instead instead of your arms to steer.
  3. I think just moving the magnets out towards the rim of the wheel would make the torque equal to a 14 incher, however there might be a trade-off in torque at speed. Maybe @meepmeepmayer can help more on this one, but from reading his torque versus speed faceplant graph, I think by having the magnets close to the center yields a higher top speed before the torque collapses to zero. I may be reading his graph wrong, and the top speed is independent of how close the magnets are to the rim of the wheel.
  4. eScooters seem to last about a month. https://mashable.com/article/escooter-lifespan-shared-new-models/ They can make them far more durable for normal usage but that doesn't address the vandalism problem. For the vandalism problem, may I suggest a simple solution: make all eScooters cost $500, place cameras and a rent a cop nearby, and when the eScooter gets vandalized, prosecute the few hundred felons in each city as felons. They'll get the message, and those that do not will be in jail causing no more problems.
  5. No one ever on the existence of this forum has had problems going from a 14 incher to an 18 incher, because an 18 incher isn't a wheel people crash on unless there's a mechanical failure. However... 100% of people who own both a 14 and an 18 incher crash on their 14 incher after being on their 18 incher. Correlation is not causality, but in this case it is. The 18 incher makes you crash your 14 incher. Everyone raise your hand (the one with roadrash), if you've crashed your 14 incher within minutes of stepping off your 18 incher. It's gonna happen...

    Beware the stroad!

    Last Thursday my girlfriend borrowed my car and then was peripherally involved in a four car wreck on a stroad. Basically, while she was stopped and about to make a left hand turn from a street into a stroad, two drivers perpendicular (on the stroad) collided with each nearly head on, with one vehicle spinning into the car stopped to her right, which then minorly hit my car and punched a fist size hole in my car's front right 1/4 panel. I think the speed limit there is 50 or 55 mph, but of course no one drives that slow. The end result was three totaled cars, and all three drivers plus one passenger all getting ambulance rides, as the forces involved was just tremendous. I'll see if I can pull the video out of my dashcam later today and post them on YouTube. From the pictures, a new Toyota Camry, a Chevy Impala, and a new BMW M5 were destroyed or heavily damaged, and the medical damage had to be quite expensive. Impala -$15,000 BMW - $40,000 Camry - $30,000 Three ambulance rides at $2,000 apiece, with emergency medical at $5,000 is about $26,000. That's the way too low to be true estimate... This is probably a $100,000 crash, at the very least. The stroad is a road design that takes what should be a minor fender bender and turns it into an expensive disaster.

    EUC tire management

    Do you have a big screen TV in your living room? You can put YouTube wheel changing instructions on your TV, and the big screen helps a lot with the details that you'll need, plus sitting in a couch with a wheel in front of you is comfortable. You'll need two sets of tire irons. Not one. Two. Four levers total. Dump the new tire in the hottest water you can find, for 15 minutes at least, so the small 16 inch tire can flow easily onto the rim. I was very surprised to find how hard it was to lever EUC tires onto their rims, bicycle and motorcycle tires are far easier.

    Gotway Nikola EUC.NYC Post-Demo Impressions

    Are the components of the Nikola better than any previous Gotway? That is, even if the wheel is unimpressive to the riders here, is the Nikola a more reliable and safer wheel? If so, then most riders here would be better off buying the Nikola over previous generation wheels, simply because a new more reliable wheel invalidates previous generation wheels, if it doesn't blow up and has more reliable power.

    Uniscoot - have you heard about it?

    YouTube's most annoying reviewer recommended it. He called the range "legit". Presumably, legit is short for legitimate for the cool suburban class.
  10. The Ninebots don't have trolleys whereas the V10 has a trolley. You can carry the IPS i5 wheel (rolley-less) and I shall trolley the very heavy V10, and we can then have a 5k footrace. Would you like to bet on yourself for money on this race?
  11. The smaller brother of the E is the S1/S2, which I think it one of the most beautiful feels due to its sleekness. Everything on the S1 has been removed, including padding, and so it's not a very practical wheel. If you're a small girl then I do not think any of the Ninebots work for you except perhaps the highly unreliable Z10, because even the small S1 is quite heavy; you need a trolley. I'd suggest just the V10, failing that the V8 OR the V5.

    Falling on Z10

    If you take the depth of a pneumatic tire (wheel rim to tire crown), and halve it, that's approximately the biggest bump you can take without doing anything special. You can straight-leg bumps that size all day long, although you might have speed wobbles if you hit the bump off kilter. Bigger bumps than that require suspension, which might just be your knees allowing the wheel to move upward. You may simply choose to straight leg everything while avoiding all bumps (which is how I usually ride).
  13. I think having flat-bottomed rubber sneakers with ankle coverage is the most important factor. Something like the Converse All Stars. If you can get the most agility possible during a crash, then that buys you time, and time buys you options. With time you can choose to slide, or roll, or even try to hop enough times to not even fall. Perversely, protective equipment makes it more likely you'll hit the ground, through less agility and through risk compensation (you use the extra safety margin to go faster). However, if you're treating your 18 incher as a 26 mph scooter, then you have no choice; full-face helmet, gloves, and all that jazz.
  14. While it might have been a pothole, it might also have been a small twig or stick. The KS14S has fender coverage that, in my opinion, is far too low and is prone to being fouled (a great argument for tires with minimal tread). It doesn't take much to completely jam the wheel, but the very act of crashing unjams the wheel.

    The perfect EUC?

    I have just two suggestions, one is realistic while the other might not be. --Make the wheel extremely reliable, as not with redundancy but simply with the most reliable components. --Three layers of security. 1. Hardware lock the wheel with a chain, 2. software lock the wheel with a loud alarm if moved, 3. GPS track the wheel.
