I just realized us EUC riders are super heroes to anyone not riding. We are. We truly are. We show the world anything is possible. We look like we defy the laws of gravity, and in a way we do, always in a controlled fall longer than any sky diver. I think what brings me the most joy is seeing the faces of people smile and not so much the riding. Keep riding.. Thank you Marty.
It was an amazing experience running into your group of unicycle riders on top of MT Wilson. It was the highlight of our trip to southern California. You are truly an inspiration to riders of all ages. You’re a rock star!
Hi Laura. I enjoyed talking with you, and I love your enthusiasm 👍 There are a bunch of riders in Phoenix so if you and your husband ever get the urge ... 😄
It can't be understated your contribution to euc sports those manufacturers should reward you financially and you should be on the box of each product consultant expertise thanks from all of us
Great share Marty. Thanks . Ugh! Now I have to go repurchase a Commander. I sold mine because of the overheat issue. I tried everything but I/we couldn’t find a solution.
wow!! awsome man!!, I have one of these bad boys(commander). struggling with high temperature same as you do. that`s a brilliant design of you!!! so cool! It reached 70 degrees centigrade when I climbed a mountain on a sunny day. I think 73 degrees is top limited and allows you to ride it, after that the pedal just warps to forbid you to stand on it.
@@SteryleBandNC Hopefully you used the same size or bigger holes. I know someone who drilled smaller holes and it wasn't as effective. Good luck, and if you remember let me know how it goes.
@@ElectricUnicycles we made 3/4 holes like in your video as close to the same spots. Tested today in 88F and it was consistent hovering around 60-65C. It usually just keeps climbing but not now. I was accelerating harder than normal and could see the temp going down at speed. 👏👏
good idea Marty, what you think putting on small piece of door screen permanently so water or dust ingress will be reduce by alot i think? instead of putting on caps.
@@krain8458 Nice. Always great to get feedback on my mods. Thanks. As long as the Commander stays moving it's now cool running for me. If you're climbing something steep and not moving very fast it can still get hot.
From my testing experience (here and with different wheels), ANY kind of filter placed in front of ventilation holes reduces the airflow by 90+%, killing any benefit. Filter material will only work if you have powerful fans forcing the air through the material.
@@ElectricUnicycles putting a fan in there could be possible. I'm thinking putting a filter in there instead of the plugs. 10 or 20% more air flow when dusty or raining might help compared to 0%.
@@ElectricUnicycles overall its a great diy hack for a serious problem. I'll pry never have a chance to ride a commander, but it would be the first thing I do!
I have another idea of cooling modification but it's more complicated. You can see it in this video ua-cam.com/video/wLunwaJg05E/v-deo.html but it's not only about cooling there are also some other modifications. You can use subtitles if you don't understand that language.
I am not certain about the location the veteran sherman measures the temp but it goes right into the red during these 103degree F days. I wonder if 130 is something to be concerned about?
That's a temperature not to worry about. When you see the temp's going north of 65° your wheel is starting to run hot. If it climbs about 70° you know you're in tough conditions and that it'll probably be getting hotter so maybe let it rest for ~5-minutes. I'd feel comfortable riding all day long at any temp up to ~65°
thank you fo rsharing experience. Are you plan sherman max solo overheat hill again? Is max realy more powerfull if have same magnets numbers and size like vanila sherman? What is you opinion becasue comander must be arealy more torque and efortless for ride compared to sherman max
The Sherman Max was already ridden up Overheat Hill (I have a video) with zero problems. I recommend the Sherman Max over the Commander UNLESS range is more important. The Commander has more range than any wheel currently in production.
now the question is if you do really cool the mosfets, or just the temperature sensor, which is mounted on top of the PCB? because if last, you don't only cheat the graphs, but also make your riding very dangerous, mosfets get hot and go undetected, then blow... I think you need more research here...
People have mentioned this for years. It's a non-issue IMO. The temp sensor has physical contact with the board which means heat transfer to the sensor is much greater that any affect from increased air flow in the control board chamber.
I'm waiting on some hydrophobic cloth to do this mod. If I knew where the temperature sensor was, I might cover it up and see what happens. Does anyone know what the temperature sensor looks like?

Thanks for those nice words 👊
Let us know when you make the “plastic bonnet” for the top Marty I would love to see it! Thanks again for this mod idea I’m excited to try it
Running cool is always good. So simple. Great thanks for sharing.
Thanks for bringing the video to fruition, much appreciated.🙌🙌
Gotta love that the wheel costs 4000$ and you are expected to make your own butt plugs!
Such ingenious ideas Marty, I like the one with the tape on the tube.
I really appreciate that you share your experiences with us! 👍😀
Thank you so much for this video. I am been trying to figure out how to deal with the overheating.
Always bringing great mods Marty. That's amazing you dropped the temps that much. Great job
Great share Marty. Thanks . Ugh! Now I have to go repurchase a Commander. I sold mine because of the overheat issue. I tried everything but I/we couldn’t find a solution.
🙂
Nice, Thank you! Love your kreative thinking!
Could probably design a 3D printed TPU "plug" to replace your duct tape
Marty you teased me so much I finished before the mod was actually revealed. :)
LOL

Thanks. Hope you can get yours to run cooler too.
I hope the Veteran people take a hint from this video and come up with a better, more permanent cooling system.
Or even ExtremeBull, the makers…
Good job marty
Great stuff Marty👍
Hopefully EB will learn something from this.
Soon will need DIY coolant lines, small radiator in front, with impeller pump connected to external fan
Did you drill the holes while the wheel was fully assembled?
No, I removed the top panel so I had the access that I needed. I didn't have to disconnect any of the cables though.
@@ElectricUnicycles TY! Another rider helped me drill the holes after a group ride today. Just need to tape it. Hope it does as well for me.
@@SteryleBandNC Hopefully you used the same size or bigger holes. I know someone who drilled smaller holes and it wasn't as effective. Good luck, and if you remember let me know how it goes.

@@SteryleBandNC thanks for letting me and everyone else know that you had a positive result and it was worthwhile 👊
Very cool
Just wait for the 3D printing community to make a clean covers that are waterproof
Like to have access to this wheel to design
good idea Marty,
what you think putting on small piece of door screen permanently so water or dust ingress will be reduce by alot i think?
instead of putting on caps.
ANY restrictions to the air flow will render this mod mute
Nicely done 👍
Once i'll receive mine i'll send you some 3d printed stuff 👍😁
Going to try this! Thank you!
Great video, thank you! I plan on doing this mod ASAP. I got mine up to 135F today, what temperature should we be cautious of? TIA
75° Celsius
I completed the mod and wow! Two in the front each one inch and three in the back 2 that are 1/2 inch and one center at one inch. Thank you again!
@@krain8458 and it did lower the temperature for you, hopefully?
@@ElectricUnicycles It sure did!! Same path... Before, 135 degrees, after 104 degrees. Very grateful!
@@krain8458 Nice. Always great to get feedback on my mods. Thanks.
As long as the Commander stays moving it's now cool running for me. If you're climbing something steep and not moving very fast it can still get hot.
Great work!! Thanks brother!!🙏
I wonder if a chain saw or lawn mower air filter would fit inside the front?

Get the EX20 the High speed version, I'd like to hear your take on it.
Send me one or the cash to buy one :-)
@@ElectricUnicycles Lol I still gotta buy one myself! ; ). I was interested in the InMotion V12 HT unitl Wrongway had a cut out on it
Did you just drill blind or did you remove the top cover ? I’m just worried about wires being in the area behind we’re I’m drilling
I absolutely did remove the cover so I could see where I was drilling. I did not disconnect any of the cabling though.
@@ElectricUnicycles thanks 😊
