  1. Found this information on extinguishers, which I thought was good to know: https://steadfastfire.com/how-to-extinguish-a-lithium-ion-battery-fire Here's an extract: "Lithium-ion battery fires are extinguished using Class B fire extinguishers. This means that in the event that a device using lithium-ion batteries catches fire, a standard Class ABC or BC dry chemical fire extinguisher can be used to put it out. Class B classification is given for flammable liquid fires. These batteries contain liquid electrolytes and fit best in B fire classification." Great link, it's the spec
  2. Here's my list, with regards to minimizing the risk of fire: Always keep the wheel inside, never in a shed or garage where humidity and the cold are the enemy; Charge by the entrance so I can throw the unit outside quickly if required/possible (I'm at street level, lucky for me). Another benefit is that it sits there vertically on a mat to collect the rain/snow; Fire extinguisher closeby; Additional smoke alarm in the entrance; After the ride, turn the wheel off and wait an hour before charging, especially if it's colder/hotter outside. That will let the battery c
  3. Really cool initiative, thank you! We can clearly see which manufacturer needs to improve the most, nice to see a clear summary in which this stands out. Both types are pretty bad. I'd like to avoid a battery fire as much as a burnt control board, or any other type of control board failure while I'm on the wheel! And I'm not talking about extreme testing like Marty's Overheat Hill runs, just regular use. A board failure (even without burning) leading to a cutoff while I'm riding at 50 km/h is far from insignificant. I could argue that board failures could lead to serious inj
  4. Yes. Had a new Mten3 myself in that container, which I cancelled and got a refund for, as I didn't want to take a chance. Had just received a brand new Nikola 100v just last week (my first Gotway and 3rd wheel after a V10F and a Sherman), and I went into a full 9.5 on the Richter scale panic attack over it! I was monitoring this thread as it first appeared 15 minutes after getting the email from eWheels. So wild. According to the theory, it was a Gotway RS 19" that burned since it was left on. Very amateurish if that's the case. I'm sure they've blamed the intern, but what about their che
  5. Mine didn't reset the ride counter. Did that manually by holding down the top left button before each ride. And the settings sometimes switched to miles by themselves (I use kilometers). I'm at firmware version 4.29 (1053).
  6. Been there. Montréal is not as rainy as northern Europe, but we do get rain (intensely so at times). And snow. And freezing rain (1998!). And slush. And dust. I had the same painful deliberation only recently. I've also been really concerned about hollow motors and their apparent weeknesses and vulnerabilities. I understand the rational behind making the axle and the pedal hangers sturdier (although it seems the 16X is very strong in that regard *without* a hollow motor, so there are other engineering solutions). The new wheels from 2020 were all pretty enticing, I almost went for the V11
  7. There we go! I had setup EUC World to automatically record tours. As soon as I swiped over to the tour screen and stopped it, these options re-enabled themselves. Thx! I will play with these settings this week to try to get a more accurate battery level reading. That's great, thanks again Seba! One thing that I absolutely prefer about EUC World is that there's a companion client for Wear OS watches. Bought one for Google Maps on the road (and keeping the phone in my pocket), but EUC World's speed display on the watch was a nice surprise. If these two issues can be resolved, a
  8. But it does. Practice lowering your head in a millisecond so you can avoid low branches that will only be visible at the last minute! 😱😁
  9. Really cool list of suggestions!! Power pads do more than help in jumping. I don't do jumps (yet?), and I hesitated when getting the Sherman in installing the ones that came with it. At first they felt weird and in the way of my legs, but I adjusted pretty quickly. They especially help in accelerating and braking (with the two vertical "bars" of padding), and that also helps to feel more locked-in to the wheel. For me they are a physical reminder to bend the knees forward by the same amount of flex on each side. Sometimes I would ride by "resting" the knees on the forward padding,
  10. Merci, et merci Mike! I've been wanting to confirm this info, created a thread to find out ("Nikola 100v minimum voltage"). It's my third wheel, and third EUC maker. Both Inmotion and Veteran were kind enough to put a nice battery level indicator (and Veteran even put the 75.6v minimum in their manual), but the Nikola was a mystery in that regard surprisingly. And the different apps reported pretty inconsistent values. The first thing I do with a new wheel is build a spreadsheet to estimate the total range. With the ride distance and battery level/voltage difference between start and f
  11. That's what I said, we're in the realm of quantum physics! Shrödinger's Battery Level Theorem 🤣 While we're on the topic of EUC World, something puzzles me. In the General Settings, the first battery option is "Battery level averaging", checked off by default. My 96.5v / 95% display was with it checked off. If I check it (with the Nikola turned on), the other options don't enable, they stay blacked out. This is different than with my Sherman where they would be enabled by checking the first option, allowing to choose a different algorithm (as well as set the minimum voltage per cell i.e
  12. Exactly. Voltage itself will vary a bit whether you are riding or stopped, it's quantum physics after all 😉 Similarly, in a car I prefer to know the percentage of fuel in the tank rather than the absolute value of liters left (and calculate it in my head from the tank capacity). And most newer cars can display an estimate of range remaining. Ah! Now I understand why the Veteran people didn't build the Sherman with an easy way to update the firmware. It's fine, I value performance and safety over ease-of-use. Such a fascinating scene, the EUC ecosystem.
  13. Ideally each rider would be able to choose his/her own preference. With my Sherman, I used the distance indicator (seriously). Once I knew what the total range was (an estimate too but pretty reliable nonetheless), I went with the ride distance on the display, which I always reset to 0 when leaving. I knew that 120 km was the range, so if I was at 80 km I knew I was good for another 40. Bottom line that's what I need to know. The voltage is fine, once you know how to convert it to percentage. I try to never go below 20%, so at 60% I know it's time to turn back. On my V10F (my first wheel)
  14. Thanks for confirming it! Now we know why the Veteran people left Gotway: "we'll make a wheel with BOTH a battery percentage indicator AND voltage"! 😁 Agreed. In theory this could actually be done with a firmware update, could even be a setting in the Gotway app: show percentage or voltage on the side display. By the way, is there a way to update the firmware through the app or EUC World? Haven't seen anything related to that. I don't even see the firmware version in EUC World, strange. Not that I have a problem I'm hoping to fix through a firmware update, but I'm curious.
