Extreme Bull Commander Cooling Mod Test

[@Michalkonin]

Such tests should be done by the manufacturer before releasing the wheel. It's great that you showed eucworld data while driving. Great movies

[@busybody1474]

Before euc riders, we had PC gamers who ran into the same exact issue, PC boards running extremely hot.. more specifically, the CPU.. one of the most popular mods to this day, is liquid cooling to replace inefficient fans..

[@HaZtile]

Maybe you should try to detach not only the headlight but also the speakers? It can increase the airflow.

[@KeithWhiteBuildsandCreations]

The control board is in a sealed box so unless you can flow fresh air across it it's gonna be hot one that will fail over time.

[@Cr125stin]

I hope they get this figured out. Thanks for the video as always! I’m going out for a ride after this video

[@bigbear7567]

Great video!

[@christams8863]

They really need a larger and better engineered surface area to collect more air in and funnel it to the motherboard. Having some exhaust fans, at the other end, blowing out hot air from the inside would help, too! The fans would create a small negative pressure gradient to draw more air in.

[@FinnBjerke]

Nive video mate. Im waiting for S20 and loving my Sherman and V11.... Thx for many good thoughtfull reviews.

[@Gebeleizis.]

Hello Marty. The fact that the rear part with the speakers was still there shouldn't make that much of a difference. You were going at a decent speed, enough to harvest a big amount of air and pressurize/push it along the tunnel and finally spit it out through the already modified exhaust. And your own MP24 experience proved it. By doing your on the field mod, I think you've discovered an engineering issue: that of poor thermal conductivity between the hot and the cold part of the system. In other words, if more airflow didn't get the system rid of more heat, means the airflow didn't have access to that heat. The heat is kinda trapped inside due to whatever design/engineering error, the are many possibilities. It's only a logical assumption, I haven't seen their design. But I might be right, and if so, EB need to do their homework ASAP. Thank you for your work and keep it going 👍

[@SwitchUpYt]

Would love to see you stick a custom heatsink in one of these Begode wheels.

[@russellzauner]

small bit of 3D printed intake ductwork and a small fan for those slow steep ones. Heck, you could use a PC liquid cooling system with two exchangers and as long as the airflow is good then your heatsink will do WONDERFULLY. Make sure to block where mud can get in so you can keep things chill - mud kills airflow and heatsink won't do much otherwise - gotta force the air to flow over something in an enclosure that was made to shed air, water, etc elements. If drilling a few holes and putting an intake on it might work, then I bet people would buy that as an aftermarket kit or I'd at least throw the plans up on thingverse to print such. If worse come to worse you could remove the heat from the cooling system with a Peltier/TG/TE chiller. Maybe airflow is enough but remember how many people had to rebuild their XBOX360 to put the right thermal management, as opposed to what it shipped with, in a product they *knew* was gonna get hot already.

[@scottsum1319]

Just a thought but how about aftrmkt fan (or dual fans using high CFM fans eg. Noctua) mod. "Wheelerspro" did a vid on this mod plus a few other waterproof mods on the M24pro (or maybe RS I forgot). The Noctua fans he used blew a lot more CFM with the bonus of being much quieter as well. I think the aftrmkt fan/s with some rear (or perhaps side inlets for bernoulli's effect) should help lots. Ofcos these are things GW shoulda done but it's GW afterall. It would be much better if GW puts out some disclaimers for its buyers to do mods if they lived/ride in hot temps. Again its GW so if we wanna ride their wheels, there's always gonna be more work involved. Great for tinkerers but not so much for most of us.

[@7belair]

Burning hot wheel. :) It's not summertime, one can expect more problems for summer. As you put it - Gw does not put any real thought into this. I think whatever the "surgery" you or any rider must undertake to make this wheel run cool proves the point. Not commercially ready yet.

[@BlackLabelExpat]

I get the feeling a lot of gotways testing just involves flat streets

[@ElectricUnicycles]

Yep :-)

[@monocyc]

I get the feeling that a lot of testing does not involve gotways XD

[@mikeintampa250]

Hi Marty, that Mount Baldy ride is a little hairy, I always worry about you standing in the road. Good attempt to cool it off and great suggestions.

[@roghaj]

The time shift thing makes it look like Zen video. check it out at 16 minutes. :P

[@roccatagon]

opening only front cap is not enough, because back panel is still closed. So this air tunnel cant work properly. Remove also back panel and try again.

[@ElectricUnicycles]

See the referenced video where I implemented the Gotway fix of adding holes in the back

[@my_euc_journey1977]

In the South, you have cooling challenges, up North its waterproofing issues. The perfect wheel is yet to come.

[@gorankirhner]

I am in the phase of deciding which wheel to buy and this one was a part of my shortlist. After this overheating this wheel falls on the list pretty much. Thanks Marty for this job this means a lot to me.

[@SwitchUpYt]

There’s only one list: Kingsong S20. It’s next level compared to anything right now..

[@davewood1982]

depends where you live also, don't forget marty lives in a super hot climate

[@gorankirhner]

@@davewood1982 I live in Eastern Europe and during the summer the temperatures go around 38C degrees, and that can be a problem.

[@gorankirhner]

@@SwitchUpYt Nice wheel, but let's wait and see the first batch...

[@patrickmckowen2999]

Great test👍

[@theanimalplanet7031]

Who wouldn't be upset that they have to heavily mod this $4000 wheel to control the potential overheating and useless light. Its laughable at this point that they still failed on the heat management. The only pro, Gotway do it right is having a big battery and HT. Thanks for the tests.

[@utbyjohan]

They could use waterproof netting in the vents too, then there wouldnt be an moisture issue at all, waterpoof netting as many shoes got in the soles for airflow

[@eucssplyce1229]

I put a fan on top of mother board just have to test. I made spacers under fan to give more air flow. Video on my page

[@BunnyslippersEUC]

The sadness in Marty's voice is real. Hopefully the Hero will be the saviour at 4000 dollar. Or 3000...still dropping?

[@ElectricUnicycles]

LOL

[@russellzauner]

When they leaked the Hero is using similar suspension to the S18 it turned in to a *real* hard sell very quickly - I'm not rich and I'm lucky I can even buy one, so I went with the S20. Even if there ends up being a difference only in preference later, it immediately forced a "last generation" vibe onto the market. But for my needs (I gave up my road bike after getting hit the second time, and I'm selling my built out RM250 to help fund this) suspension travel and ground clearance are paramount - I'm riding trails in Oregon and getting a ride to the drop zones/camp. :-) This will free up several cubic feet of space in my camping trailer where the dirtbike(s) used to be carried.

[@ElectricUnicycles]

@@russellzauner I bought the S20. Hoping it's going to be a great wheel. I love my S18 so if the S20 is only bigger that'll be great, but it's looking to be much more.

[@BunnyslippersEUC]

@@ElectricUnicycles My money is also on the S20. But I also want the Abrams. The cooling on the Abrams is ridiculous.

[@alexelmagnifico]

Hey Marty! I think your solution did not contemplate how to expel the extra airflow OUT of the wheel. I reckon that if your had opened a similar sized gap on the rear side of the wheel, it would've done the trick! 😀

[@ElectricUnicycles]

Based on similar tests with my Monster Pro, the "exhaust" isn't as important. But I'm sure it would help.

[@romiansobieszczanski-paszt4238]

@@ElectricUnicycles What video camera do you use ? Thanks for the asnwer

@@romiansobieszczanski-paszt4238 Links in the Description. Insta360 X

[@MitchG]

If they tuned the speed controller software different they could make the motor run cooler

[@Gebeleizis.]

Generally, the apps indicate the controller temperature, not the motor temperature. That's the point of factory and Marty modifying the area near the controller.

[@busybody1474]

Considering the cost of this unit, Begode really dropped the ball on this issue.. a massive heatsink will certainly conduct heat very efficiently, but the heat still needs to be removed from the shell.. A liquid cooling system will effectively pump the heat to a radiator exposed to the outside air rushing by, same as liquid cooled engines which have by and large replaced air-cooled engines, for good reason.

[@nyceuc2660]

👍👍

[@Papalou1234]

the centrifugal fan have alot more airflow that is what Sherman have!! i say if they put 2 centrifugal fans i be surprise to see the temperature!

[@rerkey]

is the temperature measure correctly? When starting, wheel temperature is 47C.Bit strange when air temperature is 18C? how the wheel gain 30C at the start?

[@ElectricUnicycles]

Because where I "started" was 20-miles and 4000-feet of climbing from where I parked my car.

[@rerkey]

@@ElectricUnicycles Marty great input in EUC community as always.

[@fubar4fpv]

the mod Gateway is doing 🤦‍♂️ wow what quality these euc's have

[@outerheaven2k7]

Really disappointed to hear about the heat...might have to think about my preorder a bit

[@ElectricUnicycles]

It does depend on your riding conditions. If you don't live where it gets very hot and you don't climb lots of hills it'll be okay

[@masterblasterofdisaster]

Please Veteran, release Sherman with HT motor and 400 extra wh and end this misery.

[@coldpanda]

I wanted the commander until all of your videos lol. Thank you for the valuable testing and videos for us to see. What a crappy company.

[@GGnext.crazycro]

You increased the intake, but didn't increase the outtake. There is the air flow bottleneck.

[@ElectricUnicycles]

On my Monster Pro I added a large intake and outtake air scoop. When I closed the outtake scoop it only got warmer by a couple of degrees. But yeah, A LOT more air needs to get into and out of this wheel to cool it down. I'll do more when I get my personal copy of the wheel.

[@Gebeleizis.]

@@ElectricUnicycles just take one of the headlights out and put a funnel in that hole. It will harvest a massive amount of air and inject it into the wheel 😀

[@DaleClark1000]

Added air in won't help much unless you add air out.

[@ElectricUnicycles]

Not based on similar tests with my Monster Pro

[@adamGeuc]

Do NOT buy this wheel, if the manufacture cant figure out cooling which is easily measurable, what else you will be TESTING for them while putting you life on the line.

[@posyp3k]

Hot wheel(s) ;]

[@Ronin_Ryder]

Disappointing. Oh well ...
