Popular Post ir_fuel Posted August 4, 2019 Popular Post Share Posted August 4, 2019 4 hours ago, Asphalt said: @Darrell Wesh Looks like you’re right about wind resistance being a minor factor. This article suggest you only need a 9.8-degree forward lean to compensate for 90kph wind. So basically the limiting factor is fear of getting bounced off the wheel at high speed. I wonder if bindings are going to start becoming a thing for speed demons? There is the "falling over" aspect, but there also is simply the fact that the wheel will have to work a lot harder to push through that wind resistance. You can't simply state that double the voltage = double the speed because the wheel can spin twice as fast. 4 hours ago, wheelr said: This got me wondering, what is the 0-60mph equivalent for EUCs?

I truly believe that the current tech it's at its peak with it being 100% down to the riders movement to control braking and absorb shocks etc.. even the 100V probably no one is actually using full speed but merely for a test in a video.. there's a point where it just becomes totally impractical with wind resistance, stopping time, lack of any suspension.. unless they plan on adding suspension and strapping your feet in, and disk brakes that come on automatically or something as well as a more powerful motor then we are already beyond any reasonable speed limit with 70.. but I can't imagine how crazy the wind resistance would be at 90 lmao half of your battery would be drained from just that Edited August 4, 2019 by Rywokast 2 Quote Link to comment Share on other sites More sharing options...

A 126V wheel would bump the usable cruise speed a nickel to the 35-40 range, not that it’s suggested or safe to do so. For reference, I consider all 31 MPH kingsong wheels 25 MPH cruising wheels. (need a 5 MPH buffer to sustain a given speed, plus kingsong wheels speed reporting tends to report 10% too fast). 3 Quote Link to comment Share on other sites More sharing options...

KS is cautious in that regard and whatever the top speed thats listed is a safe cruising speed.. 25 mph is only slightly higher than the cruising speed i constantly do on my ks16s, as i have for two years i always ride the beeper on ks and inmotion wheels.. gotway i set a safe buffer for myself and just keep it in mind.. i know its always better to have speed and not need it of course, but there comes a point where its redundant, and i think 100V is that threshold where we need to look at other possible benefits to a >100V system as speed is no longer a deciding factor.. but with that you also get other risks associated with it, as well as diminishing returns where price is concerned.. 100V models are already quite a bit more pricey than 84V.. imagine what 126V would be?? you would need some massive benefits that do not include the unreasonably high speed limit to justify that purchase if you ask me 1 1 Quote Link to comment Share on other sites More sharing options...

Gotway wheels appear to be closer to GPS. They said they are changing the distance their app is showing to closer to gps because users want that. But it reports from wheel rotations and should be more accurate than gps, if the calculation is done right. I’ve not seen the speed being massively wrong but haven’t done exact testing yet. Distance will always be shorter on gps since it measures straight line when you are slaloming. Anyway, no reason to leave safety margins on Kingsongs, they already have it. They could go much faster, the limit is not based on the wheel power but on their idea of safety. I agree with @Rywokast on diminishing returns. At some point more speed doesn’t bring any more enjoyment if one is not using those extra mph. Not that more top speed is a negative thing as long as there are no costs to it. But usually there are costs, price or feature. For those who don’t utilize the extra mph the cost is waisted. So if there are no other benefits than top speed from 126v system, it’s not interesting to most riders. 4 2 Quote Link to comment Share on other sites More sharing options...

Like Nikola 84v to 100v, and now a 126v... haha that is their standard practice.. for me i bought the 2100 wh 84V when the 100V was already out obv, i dont want the 100V nor the 126V the 84 is more than enough for me and the extra added cost would be for nothing.. plus with the 100V you get less battery even though youre paying more.. i dont know what the price of the 126 is going to be but i suspect quite a bit more than the price increase from 84 to 100, but at least you should be able to get the same battery capacity as 84.. these are mostly specialty wheels and although 100V is becoming a bit more popular now 84V is still the standard and will retain more of its value if you ask me, so theyre not really getting screwed i mean people have been riding nikolas for what five months now, in the world of EUC's thats not a ridiculously short period 1 1 Quote Link to comment Share on other sites More sharing options...

I would agree if they would release a new model every 3 months, but going from 84 to 100V isn't that much of a game changer. I don't think anyone here would sell their 84V wheel and get a 100V one.

Who wants to ride that fast? I wonder what other reasons than speed made them do this. Interesting! Getting the voltage up gives one proportional higher top speed with the same motor, as @esaj wrote. But driving at the same speed with the same burden will "burn" the same power as this motor driven with 100V or 84V (if they still can take this "operating point"). The 126 just increases the area of torque over speed == usable "operation points". As at low speeds all 3 version are strong enough to melt and unsolder their wires going to the motor this "increase" won't change to much. Just at higher speed one has more reserve power. As the wheels are already quite fast and powerfull one could go the other way and take a different motor to reach with the 126V setup the same max speed as with the 84V version. This would lead to 84/126 = 66% current needed for the same torque output. Leading to 0.66*0.66=0.44% power dissipation for the mosfets/wires and connectors. ... one would then just have 30 cells in series instead of 20... I don't know if i'd really like that - could increase the chance to get bad/aged cells ... At least some kind of cell voltage surveillance should be implemented by then... 1 3 Quote Link to comment Share on other sites More sharing options...

It's kind of like complaining that there are too many choices for toothpaste - makes it so difficult to choose. Yes, a valid complaint sometimes.

Hopefully the upcoming weekend I'll finally be able to test them side-by-side to determine any quantitative differences (torque, etc.). For me it's the bigger battery. I can ride the Plus hard and still get absolutely amazing range. That's why it's so much nicer for me. 1 1 Quote Link to comment Share on other sites More sharing options...

I said that I prefer the Nikola Plus. Just so happens that the Plus is a 100-volt wheel. When I get the 126-volt Nikola, assuming that it's 1600wh, I'll finally be able to do a apples-to-apples comparison between the 84v and 126v versions of the same wheel. Maybe we'll discover that the higher voltage wheels actually get better gas mileage. Finally, I do plan on some direct comparison between the 100v and 84v Nikola's to see if I can tell a difference in torque, acceleration, etc. Then I might be able to say 100-volts is better in every aspect (except cost) 2 Quote Link to comment Share on other sites More sharing options...
