Whatever happened to www.eucspeedguardian.com?

Remember these?

You install a little dongle inside the EUC and then this thing onto your helmet and you got a visual warning rather than the beep which are already an outdated means of reporting back 80% power draw with such wind and noise at those speeds 60+mph.

Are they still available or have someone else made something similar, or am I just completely old and outdated because all the cool kids already use something far better?

They only supported up to 100v wheels IIRC + EUC World/DarknessBot PWM alarms over bluetooth happened killing the need for dongles and gadgets.

There's a lot of drama around the original creator, involving a lot of individuals who purchased, but never received the items they paid for. Said original creator also no longer makes them and doesn't support modern wheels.

In light of that, there are a few of us that developed our own versions, so they are floating out there if you want them. A lot of people have gone to bluetooth as it is a viable alternative, but there are drawbacks. The first drawback is that all app based alarms require calibration and constant checks to ensure they stay calibrated (not too big of a deal generally). The bigger issue is that bluetooth protocols are not very fast, and the delay between the wheel transmitting data to your phone and then your phone relaying those alarms to a headset can be too slow that you may exceed the wheel's limits before the alarms kick in. Some of the first generation of 134v wheels were notorious for really bad bluetooth delays/ very slow polling rates. 

The speed guardian, on the other hand, offers a completely independent alarm system. It's actually a very dumb system that just relays a signal to a receiver whenever the transmitter is triggered. In this case, the transmitter goes off whenever the wheel's beeper goes off so it's both a pro and a con in that it will relay beeps very quickly, but it's also bad in that it relays every beep it gets. Doesn't matter if it's a pwm beep or a headlight activation beep or a low battery beep, all of them will trip the relay. That's not to say that the speed guardian is 100% reliable either. If the wheel never beeps, the transmitter and relay never beep either, so this will not save you from sudden cutouts (nothing will)

Here's the best part though, since the SG runs on its own frequency and doesn't clog the bluetooth channel, you can run a bluetooth device and a SG to get the benefits of both. That's what I do

Thank you so much for that in-depth explanation, I greatly appreciate it! Maybe SG is completely useless nowadays... I just remember barely being able to hear my 80% beeps on the RS19, and that was soooo scary, and my top speed @ 80% beeps was 69kmph (43mph). I imagine wind speeds at 60 mph makes it even more impossible to hear, even if it's a larger, louder piezo. 

Maybe I'm wrong, and they largely improved the piezo positioning and loudness, to the point where you can hear the alarm at 60mph with a full helmet on? 
There is just no way in hell I'm hitting 60 mph without being able to hear an alarm, that's beyond terrifying, so I figure I may need something like a homemade SG in the future?

Can anyone elaborate as to whether or not you can hear the beeps at 60mph, with a full helmet? In any case I think having 2 warning mechanisms to be preferred: 1. the regular piezo 2. Homemade SG for visual beeps.  

Who still makes these, and are there any 151-168V models in circulation?

In my opinion, there is no stock piezo on any wheel that is sufficient above 40mph. LeaperKim probably has the loudest stock buzzer, but even that cannot be heard above 40. Personally, I would say that if someone plans on spending time above 40mph, they need to be running some sort of additional safety alarm. Whether that is just bluetooth or just a SG, it doesn't really matter, but they should be running something extra, anything really. 

For my own built SG, I run 3 systems off of the unit (piezo, vibration, and LED indicator). I do not find the vibration very noticeable, but I can always hear the unit and see the LED. Even at 60, I can still hear the SG through my fully enclosed helmet, especially since I have the SG mounted right next to my ear. 

As far as I am aware, there's currently only two people that build these things. One is Trung (Squallheart on telegram), and the other is me. You'll eventually be able to purchase my version from Roger EUC's website (under construction), but my version(s) are capable of supporting all begode/extreme bull wheels, and I think I am the only one that has support for leaper kim, but I have only done testing on the lynx (untested on patton, sherman s, etc so not 100% sure it will work).

Thank you so much dude! Every bit of information I needed

I'll certainly pick up one of your SG's once it's available on the website, and one of his roger chargers too. Great initiative of you to keep this much needed technology alive and evolving! You should probably come up with a different name to separate yourself from the questionable history of the original SG. 
I think the product you are making has a LOT of space to grow in the market, considering how many people ride above 40mph. This could be the next charge doctor or Roger charger, in the sense that it'll see wide adoption and become universally known. I wish you the best on this business venture of yours, I'll certainly support you!

If a wheel has PWM based tiltback, would this feature be good enough on its own in your opinion?

I only made this thread because I want to avoid that. I'm aware it exists, but I don't like tilt-back and consider it dangerous for my riding style. But if you're just a casual rider it should be fine, however I have read about a few people finding the tilt-back too smooth and incremental that they don't notice until it's tilting quite a bit.

That's going to vary from rider to rider. I personally don't like tilt back and find it to be unsettling especially when you have to put a lot of lean into getting upwards of 55+. For me, getting yelled at by an alarm through bluetooth or SG is a more cut and dry message than subtle tilt back. It's all personal preference though.
