You hold it with your right hand and your left hand in your back pocket you gotta put it on a 45ﾟ angle where 2 different color shoes cough as you're doing it it'll all work out at the end.Lol great video brother. Peace and Happy Riding Always
I am on 56 and an iPhone so I will have to hold fast. I am going to check my voltage to see what my reading is. All very interesting stuff. Thanks for the video
I watched your video and found the upgrade tool when I pressed the button to upgrade. It was both worry and expectation. Fortunately, the smooth upgrade from 1055 to 1058. The driving experience improved the problem of turning pedal forward, the turning power was more obvious, and the acceleration torque was enhanced; Thank you very much for sharing the video about updating the firmware through the app
@@ElectricUnicycles Can you share some of the riding experience after the update to 1.0.58; among them, there is a little concern, whether there is a higher average temperature of the car due to this version difference (high temperature)
HEY from hoover Alabama. ive had my sherman for about 2 weeks and im just know getting the hang of it. i am currently on bed rest because ive crashed so many times. you just made it look so easy, but it is NO joke getting to learn to ride this thing...
Adjusting voltage I propose to: 1. Charge full like you said 2. Meassure battery voltage with exact multimeter on batteries. 3. Adjust according to that (real value) Why? Im pretty sure used wheels wont reach actual 100.8, maybe not even new ones. I heard there should be a diode on the charge port (though I doubt it as my wheel loads my charger capacitors after shutting off, have a built in display) so need to meassure directly on batt pack connector CAREFULLY not to short of course.
You are absolutely correct. Just way too much effort IMO. Assuming 100.8-volts is close enough for me, considering that when you are riding at those low voltages you are only going a few miles per hour.
I wonder if it actually affects operation... Or if it's just read out. For sure i don't think it will affect BMS and balancing, but who knows it might affect the "charging shutoff stage"and in that case it is VERY IMPORTANT to have the right voltage, though i doubt it as it could be a risk (fire and all that). On the other hand BMS will keep leaking so result would be that it never shuts off if adjusted wrong...naaah won't happen as then it wouldn't shut of as batteries degrade
yup, exactly. No reason to calibrate by guessing, total waste of time. My chargers only put out 100.5v . If I were to simply guess and adjust to 100.8v it would be inaccurate, therby missing the point entirely. I doubt the user adjustments for voltage have ANYTHING to do with the values the bms relies on.
Worked on my version 1. It was updated via a chip and then eventually ota. Battery reported was off by 1.5v, verified thru testing at the pack. I havent really noticed much difference aside from that.
Hi Marty, does updating the firmware change the flashing lights from blue to red? Also, when you were doing the no load test it sounded like your bearings were rough. Excellent information though and thanks 👌
@@jansvoboda9778 I'm so happy that it helped you "up" your firmware. And that .58 is a great upgrade. I'll try changing the way the app works by asking for location permissions instead of the old android manifest way, will add a splash screen and i will host the firmware & changelog files to a secure webserver instead of a squid based home server in China.
@@LefterisEl on S20 FE 5g app crash help lock screen to portrait mode ,becasue when app switch modes crash. Disable autorotation fix this to full stable state. 😍
Does the voltage calibration transfer to the voltage that the wheel reports to the app (EUC World) as well? That is, does the app also report the recalibrated voltage? Thanks!
Apparently you aren't aware that 95% of Sherman owners never see 100.8-volts. It's not due to a bad battery or shoddy software. It's called low-quality A/D converters not instrument-grade A/D converters. That's the purpose of the new calibration function, as explained in the video.
The update worked great for me. Wasn't sure it was worth the risk, but that voltage adjustment convinced me to give it a try. Found that the wheel feels a lot more nimble under 1.0.58 than it did under 1.0.56 (V1 version with original rim), and motor control feels a lot smoother. When riding seated it was vibrating forward and back at certain speeds, now it's just as smooth as butter.
thx fo info. Maybee update just reset calibration and this fix ride feel? When you make last calibration before you remember? Is better or same pedal dip (angle cahnge) behavior in long turns? What mode you ride hard medium soft? Becasue on soft mode i have 1.0.56 and V2(red butons) i have problem make fast turn pedal dip down and i no have mental power keep stay on pedal with this dip. This is why i prefer medium mode PA+1 (pedal aligment). You feel on 1.0.58 this dip in soft mode too? @ElectricUnicycles say i think same. This app is internal leak from person who have waranty problem and distributor send him app to "Fix" EUC. But buyer make app public "leaked" i dont expect funcion like mileage wipe in end user app but i like is here. Big thumb up for Veteran to acept this and keep download link worked. 👍🏻
@@jansvoboda9778 Feels like more than just calibration, it's now almost as nimble as my Nikola+! I ride in hard mode always. There's still a slight pedal dip (56 was already an improvement over my original V1 version, forgot which it was, and 58 is better still).
@@supercurioTube My Nikola also has the same symptoms, for years. Except for the noise it hasn't been an issue. Doesn't seem to affect the range either. And strangely, I kind of like the rhythmic sound.
hello. i am just getting into this community and learning what i can about EUCs. Your videos are very enjoyable and informative. Thank you. So did you paint your red sherman or buy it like that?
@@ElectricUnicycles sorry, I think I didnt explained properly. I reference to 19:17. Is there any advantage of not having the pedals parallel to the ground?
Adding some tilt can assist in braking and acceleration. If you have the pedals tilted slightly backwards it can be easier to accelerate. And when I'm descending a long (miles) trail I will often add a 2-degree forward tilt with reduces the amount of effort required to continually brake while descending
Who does firmware to get tilt back to go more than 50kph? There must be a fix? A old z10 can be moded to 58kph. I want to buy sherman but not if the tilt back is slower than old z10. Someone must know how to fix sherman. Who?
Tilt-back on Gotway and Veteran wheels can not be enabled for high-speeds. Most people who ride Gotway and Veteran wheels turn the tilt-back function off. Then you can go as fast as the wheel allows (~80kph for the Sherman).
@@ElectricUnicycles uniphsyco went 88kph on sherman. Wrong way cut out at 84kph. Old sherman went 58.2kph with tilt back. And as voltage drops tilts back. Mr wrong Way demos it well. Until it tilted him back to a stand still. No cut out. 190kph is top setting. but the firmware should Allow acceleration toward 190kph unless voltage drops then tilts back. Thats how it should work.
I love the Mten3 next to Mighty Sherman, very appropriate. The 2 wheels everyone should have. Marty thx for all the good tech help over the years.

Anyone else noticed beeps started sounding off earlier into the free spin after the firmware was installed?
My wheel won't connect to the app when I search for it. Trying to unlock speed and update the Sherman max
Hi Marty, does updating the firmware change the flashing lights from blue to red? Also, when you were doing the no load test it sounded like your bearings were rough. Excellent information though and thanks 👌
The light color is hardware, not firmware configured. You'll need to buy a new headlight if you want the red. Yeah, I may have some bearing issues.
Oh you didn't mention that I forked it into a complete English version of the app 😥
Sorry. I didn't talk too much about the app. I figured when people found the app they'd also find yours.

6:37 my Sherman always goes above 101. Usually to 101.2 V
Does the voltage calibration transfer to the voltage that the wheel reports to the app (EUC World) as well? That is, does the app also report the recalibrated voltage? Thanks!
There's only one voltage measurement and it's displayed on the LCD and in all apps that connect to the wheel.
My Sherman shows 100.8v when fully charged. If your Sherman isn't showing that, it's either due to a bad battery pack or shoddy software.
Apparently you aren't aware that 95% of Sherman owners never see 100.8-volts. It's not due to a bad battery or shoddy software. It's called low-quality A/D converters not instrument-grade A/D converters. That's the purpose of the new calibration function, as explained in the video.
Do one for the Begode wheels. (If you need instructions, let me know.)
When I get a black control board and need to update the firmware I'll probably create a video :-)
Should I calibrate on charger or after voltage dropping and levelling after disconnecting the charger?
After you charge and unplug the charger.
You plan make range test again with new firmware?
No

Hi, are the bearings ok at Sherman? When I listen to it, I don't think so ☹️
Could be, but it still feels great when I ride it.

Probably not so noticeable with wind noise.

So did you paint your red sherman or buy it like that?
See my Sherman Playlist. I reconstructed the "red" Sherman and painted it in the process.
What is the reason for tilting manually the wheel with some amount of degrees?
The wheel can't be balancing while the upgrade takes place
