Many NYC Tesla riders who are dying for more speed will disagree with you. Plus IMHO, the 3" wide wheels in the 16" Nikola and 18" MSX feel relatively the same to me, just like the 2.5" wide 16" V10F and 18" KS18L/XL feel relatively the same. 3 1 Quote Link to comment Share on other sites More sharing options...

I agree somewhat on the V10F/18XL front, but I don’t think the physics of riding into a pothole (or other dangerous obstacle) care how wide the tire is. Surviving one is helped by a fast acting firmware, powerful wheel, and a large diameter tire. The tire diameter is of course not the only thing to consider, but when going past 30mph I think it is crucial. Quote Link to comment Share on other sites More sharing options...

Surviving one is helped by a fast acting firmware, powerful wheel, and a large diameter tire. At those sizes, 2" increase in tire diameter is not nearly as important as a 2" difference in tire width, and I've hit potholes plenty on all manner of sizes of EUC here in NYC. This is why I sold all of my 2.125" thin EUCs and will never buy/ride one again so long as I live in this swiss cheese paved city. 30 minutes ago, mrelwood said: The tire diameter is of course not the only thing to consider, but when going past 30mph I think it is crucial. I respectfully disagree, wheel weight (ie. the wheel being heavy) is much more important IMHO. I went literally flying into a parked bus from hitting a bump at near max speed on the 37 lb MCM5, because it was too lightweight and too fast, a very bad combo looking back. If the wheel had more weight, it would have landed faster so I could have braked or maneuvered away in time. This is also partly why I believe the MSX/Nikola & V10F/KS18L pairs feel & ride so similar, because of the tire dimension combined with similar overall weights.

Not correct. Objects of different mass fall at the same rate in a vacuum. In air, the one with the lowest air resistance falls faster. 1 1 Quote Link to comment Share on other sites More sharing options...

Er, this is not some kind of math problem, the heavier wheel doesn't lift as high off the ground either as the lighter wheel. 1 2 Quote Link to comment Share on other sites More sharing options...

But I fail to see how it helps with a vertical obstacle, other than having slightly more air volume to be compressed. As replied by @Jon Stern, the weight of the wheel does not affect it’s vertical acceleration. But a light wheel with the same tire pressure will probably be bouncier, and could indeed get more air time. And: 51 minutes ago, houseofjob said: and too fast This seems to be the reason you crashed, but it has got nothing to do with tire diameter comparisons. I was happy to notice that the 16S handles in a much more stable manner on various rough conditions after switching to 2.5”. But I was talking about a simple vertical obstacle, which I believe is the main reason for the wheel to get stuck in a pothole. I have no doubts that the difference in handling between Nikola and MSX is small on a flat surface. But riding up tall curbs, or large roots, rocks and potholes is notably different on any 16” vs any 18” wheel, there’s no way around that.

But I fail to see how it helps with a vertical obstacle, other than having slightly more air volume to be compressed. In my experience, it's about the stability of the landing. No one ever rides into a pothole on purpose, it's by accident. The wider tire gives you a better chance of righting the ship when you land in the incongruous pothole dimensions, instead of falling. Of course, if you can dramatically increase the diameter to shrink the depth of the pothole in comparison (ala 22" Monster) that is a big help as well, but just 2" bigger? Not as big a difference there that I would take over widening the tire IMHO. 16 minutes ago, mrelwood said: As replied by @Jon Stern, the weight of the wheel does not affect it’s vertical acceleration.

And: No, they're not being dropped from the same height in isolation like in some math problem: it's the total trajectory. The heavier wheel does not get as much lift off the ground and thus does not travel in the air longer than the lighter one.

Popular Post Shinra Posted May 16, 2019 Popular Post Share Posted May 16, 2019 Got the Gotway Nikola yesterday, what a difference with the Inmotion V8, my first wheel. Huge vehicle and tire. It's like you sit in a Mercedes, and before in a Toyota. Gonna put the tire pressure to 37 - 38 psi today, like with the Inmotion V8. You can put the music really loud, I have a JBL Extreme bluetooth speaker, the speaker in the Gotway Nikola goes louder, but not as clear. Good enough though. Very happy with the purchase so far. 3 4 Quote Link to comment Share on other sites More sharing options...
Shinra Posted May 17, 2019 Share Posted May 17, 2019 How can you easily see how much battery life you still have? There's no indicator on it like on the Inmotion V8. I watch the volt screen. Do you always have to open the application to see the battery percentage? Quote Link to comment Share on other sites More sharing options...

Use the voltmeter i realised many prior don’t know how to read the voltage on their wheels and rely on percentage. Coming from an escooter background in singapore, we always look at voltage instead of percentage. For the nikola, it’s a 72V system(not 84V, that’s just max charge). a 72V system is a 20S(20 series) system full voltage would be: 20x4.2v=84.0V cut off is 20x3.0v=60v in essence, you have 24V to play with 1 2 Quote Link to comment Share on other sites More sharing options...
Popular Post Garrie Lim Posted May 19, 2019 Popular Post Share Posted May 19, 2019 (edited) Gotway msx and nikola: 20S 72V system Gotway msx (100v), monster: 24S 88V system A typical 18650 cell has a max charge of 4.2V and a safe cut off of 3.0V Joining cells in series increases voltage, but capacity doesn’t change Joining cells in parallel increase capacity, but does not increase voltage Nikola: 20S6P config total of 120 cells 20 cells joined in series, which is then multiplied by 6 of these blocks. A panasonic GA cell is 3.45ah 6P:20.7ah so the nikola is more accurately a 72V 20.7ah 1449wh wheel thats if u use the traditional nominal charge(average) of 3.6V per cell 3.6v x20 =72v however for marketing purposes, to make everything seem “more”, manufacturers overstate the specs and round up the final number using the “newer” 3.7v nominal charge as a starting point, 20x3.7=74 74vx20.7ah 74vx21ah=1554wh ~1600wh thats how the magical 1600 value Comes about.

Ivan Zemlyachenko Posted May 21, 2019 Share Posted May 21, 2019 Hi everyone! Question for Nikola owners: have you encountered any problems with front light? In my case during the night rides it sometimes turns the light off, then in a second light turns back on and the wheel plays the activation sound. It doesn't affect the ride itself, but definetely doesn't seem to be normal behaviour. 1 Quote Link to comment Share on other sites More sharing options...
