How can i check if i got "real" speed? If i use euc world which speed should be real one - gps or wheels? Quote Link to comment Share on other sites More sharing options...

Paul A Posted June 11, 2022 Share Posted June 11, 2022 Still need to ride a specific distance to determine which reading is correct. They both could be incorrect. Perhaps one lap of a 400 meter running track. 1 Quote Link to comment Share on other sites More sharing options...

Paul A Posted June 11, 2022 Share Posted June 11, 2022 How does the alarm determine when to sound the alert? The alarm might be using a speed measurement device/sensor/reader that is not accurate? Quote Link to comment Share on other sites More sharing options...

On the 18xl, one way is to check model reported, the new 18xl reports as 18LH on the bt info. Or maybe use EW's gps speedometer to check if you are at ~31mph or ~27 GPS when the wheel reports 31.

Paul A Posted June 11, 2022 Share Posted June 11, 2022 Don't odometers on cars work on the number of revolutions of the wheel? Though changing tyre size, or even the wearing down of the tread, might have an effect on the accuracy. Quote Link to comment Share on other sites More sharing options...

The new one is faster. Edited June 11, 2022 by enaon 1 Quote Link to comment Share on other sites More sharing options...

I guess "alarm" are triggered from euc speed not GPS. I figure GPS speed are the "more" accurate one. 16 minutes ago, Paul A said: How does the alarm determine when to sound the alert?

Thought using multiple aps, to see what speed they show, when euc triggers the alarm. 11 minutes ago, Paul A said: Don't odometers on cars work on the number of revolutions of the wheel?

Could you make a "new" tread to move this conversation over. So we can take this over somewhere else. Don't want to keep stealing this tread with my questions.. I'm sorry for being a naughty boy.

Tawpie Posted June 12, 2022 Share Posted June 12, 2022 (edited) 5 hours ago, EF95 said: Is there a way to tell if the v11 i get is from the newer line or previous line? If it were a KS I'd say that the date of manufacture shows up in the KS app (and EUCWorld) in the 'details' section. It might be there on IM wheels as well. The issues I've heard are: bad batteries, necessitated a firmware update to prevent fires. And missing screws. V11s from all batches have had what I consider more than their fair share of MOSFET failures, these typically happen fairly early on into the ownership if they're going to happen (ride with fear full gear for the first 500 km!). If the newest firmware is installed and it doesn't scream at you to please repair when you plug it into the charger, you should be over the battery hurdle. A quick (haha) disassembly will reveal missing hardware, or loose hardware. Personally, wheels are such a crap shoot these days that I wouldn't be any more worried about it than anything else. Which sucks, but it's kind of the way it is. Edited June 12, 2022 by Tawpie 1 Quote Link to comment Share on other sites More sharing options...
meepmeepmayer Posted June 12, 2022 Share Posted June 12, 2022 Side note on wheel speed vs. GPS speed: These are both valid speeds (or can both be wrong). The real track a wheel goes (with carving and weaving and whatnot) is always going to be a bit longer than whatever track, made from a series of straight line segments, a GPS measurement will produce. Have you ever seen how rough and inexact these GPS measurements are? Of course it's underreporting the speed then. Naturally, a wheel's alarm always goes by wheel speed (as measured by tire rotations), because that is the only information available to the wheel. Which one is your "real" speed is up to you to say. 1 Quote Link to comment Share on other sites More sharing options...

So if i have bigger diameter tire than "original", i would be correct to assume that that tire would go faster vs smaller diameter tire? If both where going same motor power "watts". Bigger tire = more speed, or is that wrong? Quote Link to comment Share on other sites More sharing options...
Paul A Posted June 12, 2022 Share Posted June 12, 2022 If: Original tyre has a circumference of 1 meter. Bigger replacement tyre has a circumference of 2 meters. Then with one revolution, the wheel thinks/states the rider has travelled 1 meter. The real distance travelled is 2 meters. Would take more power to rotate a bigger wheel one rotation. 2 Quote Link to comment Share on other sites More sharing options...

If both where going same motor power "watts". Bigger tire = more speed, or is that wrong? Yes. Speed = RPM times tire circumference, so the wheel gives you its speed depending on the tire size it expects. If the real tire is bigger, you're going faster in reality. You'll need more power to turn a bigger tire at the same RPM, though. So you can't go faster for free (wind resistance also doesn't care and grows with speed anyways). To get back on topic (maybe), everything with EUCs is somehow a mess. Even wearing down a tire is going to lower your real speed (a tiny bit) but not what the wheel tells you the speed is. We ride anyways, and 99.999% of the time everything is great 2 Quote Link to comment Share on other sites More sharing options...
Magman116 Posted August 5, 2022 Share Posted August 5, 2022 I know I was pushing it, but my new model KS 16X has been up to 33.7mph without cut-out and on a full charge with pedals tilting back. I have held at 28-30mph for about 3/4 mile without issues. I know other people have had cut-outs at lower speeds, but mine seems to be doing just fine. My 16X is at my Boss's house right now as he is in EUC training. Regardless of the wheel, you need to get to know your particular wheel even if it is the same model and series at another's.

And sooner or later you will kiss the ground. You will see. You can ride 5000miles like that and one day it will fail you. Each time you hit those 30mph it's like gambling - one day you will win.

I totally agree and have to be prepared every ride for the inevitable. I don't get on the 16X much anyway since I got my RS HS. No matter what, I always fully gear up before every ride, even the short ones. 1 Quote Link to comment Share on other sites More sharing options...

I just wear wrist guards and go under 20kph speeds. More like running speeds, simply enjoying slow ride. Quote Link to comment Share on other sites More sharing options...
Magman116 Posted August 5, 2022 Share Posted August 5, 2022 It is nice to have the freedom to choose to do what we feel is right for ourselves without having someone else's opinions forced on us. It is not my place to say what anyone should be using for personal safety, it is personal. Just because I wear all my gear doesn't mean everyone else should regardless of how I feel about it. It is a personal choice. I feel the same way about these wheels. Manufactures should allow the user to choose what they feel is safe for them even if it means they crash. Crashing is personal too based upon choices you make. We should have things like standard profiles for wheels to choose from, then the more advanced options where we can customize the performance/safety as we see fit. Gotway/Begode is the closest thing to that now, but still not really. It would be nice to an app/wheel that allows tuning of things like phase current, tilt-back, alarms, speed limits, PWM control and many many other things. I don't see that happening anytime soon. 1 Quote Link to comment Share on other sites More sharing options...
