  1. Life is unsafe, knowing the risks helps. Kart racing is probably around the same level of safe (also loads of fun!):
  2. Anybody notice the Airwheel pedals? (used on the Q and X series wheels) I think I might know where the guts came from....
  3. I ride motorcycles, sometimes I wear armored gear (in one instance a full-face helmet saved my life), usually I don't. Not wearing gear doesn't make driving a motorcycle any safer. I ride fast hoverboards, usually "slowly" and without gear (however, when riding "fast" I wear gear). When a sensor went bad at very slow speed and tore up my knee resulting in 9 months of rehab, wearing gear wouldn't have helped. Random failures happen in high-current electronics, ignoring that doesn't mean it won't happen. Wheels, though, unless I'm going slow I wear gear. Thanks to several of the member
  4. We're all naked under our clothing... I'm pretty sure @ShanesPlanet rides without underwear, something has to be giving him super-human speed and confidence. We should be more worried every year, EUCs keep being able to go faster/farther. The farther we ride the more chance of distraction (goats, in one member's video) and fatigue. Wearing gear is like having life insurance: You're still going to die, but the risk of catastrophic loss is minimized.
  5. The electronics in electric mobility devices (powered chairs) have a limited lifespan. They're made of quality components, not the cheapest bin parts in the Chinese electronics open market that day, yet they will fail. EUCs basically use a simplified version of those electronics with no error detection/correction code, and no backup circuitry, so if a sensor fails random things happen. (A mis-calibrated sensor resulted in tearing up my left knee and 9 months of rehab.) Electronics do fail. Electrolytic capacitors and heat sink compound dries out (there are people who re-cap amplifiers bef
  6. Scraptastic! The best use of two dollars and seventy-five cents I've ever seen. (And you're not even from India!)
  7. Why ask Tesla to make an EUC? You could just overpay for a Gotway--same thing.
  8. If you put a cigarette between his fingers...
  9. Has anyone performed routine maintenance on the air pistons? Can it be done? On motorcycle suspensions air pistons require a clean/lube annually to keep the seals from wearing out. There seem to be a lot of wear points on EUC suspensions, I'm wondering how this is all going to work out...
  10. Many of the products from China are declared as low-value "repair parts" to avoid taxation. As a note, if your $2,500 wheel is shipped as $50 of "repair parts" and they dump the cargo container so the ship doesn't sink during a storm, you can file a claim for loss ($50). Or say there's a container fire because a Gotway/Begoaty lights up and torches the container. You might recover $50 minus your expenses in doing so.
  11. Just discussed in the update thread: : No Apple plans in the immediate future.
  12. 5-star android review submitted Although I only use free features I have a mulit-year upgrade to support @Seba--it's that good of an app and I'm thankful for his sharing it and putting up with us.
  13. Every year new models come out that are noticeably better than last year's models. So if tradition holds, another 4 weeks (about shipping time for some of us) and the new wheels will be out! (Or because of trade agreements and COVID nothing innovative will appear until Fall, who knows...)
  14. It appears the cooling strips (stickers) might be best used as a two full sheets the same width & length as the battery pack, placed on each side of the welded battery pack, directly against the cells, and held in place by the PVC shrink wrap (blue plastic) placed over the cooling material. If a cell were to go critical the sheet would cool the cell and all cells immediately surrounding it in a similar manner as shown in the demonstration video. This cooling effect may stop the chemical reaction in the critical cell, though more importantly should stop surrounding cells from heating to the
  15. I believe the highest voltage well-tested board is 100V. There is a 150V board under development, but high voltage brings design issues along for the ride. With power usage being constant, current generates heat due to losses, voltage does not. However, as Bryan states, pushing components to their limits invites risk of failure, and he wants a larger safety factor.
  16. King Song: 14D/S Controller https://www.ewheels.com/product/king-song-14d-s-controller/ (i did not find one on eBay or AliExpress for the KS14D or the KS14S. you may try eBay in countries closer to you and be successful, possibly Russia where the wheel was popular)
  17. In 2017 Google moved from watch apps being bundled in the phone APK to stand-alone watch apps. As of March 10, 2021 Google no longer supports bundling. Watches need updates so they load apps on their own, or you have to side-load older apps onto the phone that have the watch "mini-app" packed with the phone app (your mileage may vary on this). This change happened because watches when they were introduced were more like external screens for phones rather than smart devices--more like a "remote control" for the phone. Google wanted "smart" watches to actually be "smart" and run independently of

  19. What about the powerCON TRUE1 TOP (True Outdoor Protection) for heavy-duty and harsh environment applications. 16 amps, 250 volts, come in both panel connector and plugs.
  20. Many here use AliExpress for parts, others use EUC/EScooter dealers. You will most likely want to check battery voltage with a meter while checking the fault lead (the third wire in the 3-wire plug) on each battery. If you can see that proper power goes to the main board, the fault condition is not triggered, and the board looks good, then check to make sure the power switch works properly; sometimes simple things can create large problems. The switch usually does not fail but it is easy to check. Maybe it is an easy problem to solve, I hope for you that is the case.
  21. Uh, sorry to hear that. May I offer you a tissue?
  22. Regarding your side note, Regarding that...it's hard to test CFM (as most people don't have the equipment to do so), so it can be "generously [over-]rated" without much consequence. It takes an ever increasing amount of power to move more air due to pressure differentials, so two 10 CFM fans probably won't move as much air as one 20 CFM fan as they don't have the fan blade surface area (resulting in increased fan body thickness) to build that pressure. When sourcing fans I don't look at "Rated CFM" as that's usually exaggerated (and your actual CFM depends on how the fan is u
  23. ^^^ That man will take every opportunity to talk about his saggy butt.... -- Why don't people in trailer parks invest in the stock market? Because their money is tied up in bonds.
  24. In the city things are close to your body and you are going "fast" quite easily (it is a relative perception). In the country there is not much around and you can go much faster even though it seems like you are going slow. (You will notice how fast you are going if you fall.) When going fast the electromagnets in the motor have to work much harder to change the magnetic field very quickly, and the fixed magnets pass by fast so there is not much reward for their effort. Electromagnets are inductors, so they naturally want to maintain state; changing state quickly requires a lot of effort.
