Great video. Now you can do this for all new wheels that you sell 👍
I think we will start making this a habit with our new repair centre and extra space
Agree! Would love to see a T4 teardown.
Very thorough and informative! I hope you can get Albert to lead more teardown videos.
I wish EUC companies would make tire changes easier.
yah, why not mounting connectors in place witgout going to controller box. Thats more actual on OG or Max Sherman, as there is plenty of room
Huh. To be honest I expected things to be a bit better up close. More silicone, proper hex bolts, etc. Overall its definitely a good wheel, and for $3200 from aliexpress id say its worth it. But for 4200 I think its sub standard.
Keep in mind, this is a pre-production model. Veteran is taking our feedback before going into production.
With that price tag waterproofing should be a number 1 priority.
Pedals seem a bit gimmicky , but who knows , might turn out to be a winner.
More testing needed 😊
Thank you for doing this very informative video , I vote for giving the people what they want, YO!
Really appreciate you doing the tear downs, especially with someone as knowledgeable as Albert, as it gives us all a better understanding of where our money is going and shows the commitment to transparency. It also allows for a stronger relationship between consumers and the manufacturers, and that is a relationship that benefits everyone.
For me to buy this wheel at that price, I want much better waterproofing with proper quality gaskets around the motherboard and easier tire change. All else looks promising but holding out for more testing. Thanks guys, very informative! Also, I noticed Lucas dyed his mustache in the last video, no way it grew that much in a few days… nice try.
HAHAHAHHAHAHA!!!
outstanding, glad you guys are doing these breakdowns.
Thanks Zen!
i built an ebike about 15 years ago when everything was DIY. I was never really fond on direct drive hub motors because of how they shaved down the axle flat with the wire coming out of it and bolting it onto a bicycle frame hoping for the best. That was all you had back then. Looking at this, it looks like those days are long gone. Four big bolts directly onto the axle, doesn't look like a mickey mouse job some dude put together while drunk. I like it
The people is happy :-) thank you 😊
Picky customers are the ones that help make good products.
Dude this video gave me life. I love this channel. Thank you for giving us info on this wheel. So sick!!!
Thanks Trevor! We appreciate you watching!
These guys know their stuff!
Albert knows his stuff. Me on the other hand…. 😂
Наконец то!
Нормально сделанный вал и Нормальные подшипники!👍
Albert was very excellent. There are many issues that are concerning with the wheel and I don't see them redesigning to fix them.
The Sherman S will pair well with my Master Pro!
All the screws should be hex. Veteran definitely should make accessing the tire easier.
Albert, good job explaining. Good tear down
Great tear down. Love that you did it so I don't have to, I know what to expect... 👊
If you have to do all this just for a flat tire this will sadly be a dealbreaker for me, I hope they come up with a easier way to change the tire.
Great breakdown. Thanks for showing us!
Hope companies will take notice if you continue to open up new wheels and improvements will be made knowing this. Thank you!
Hey Eevee’s, I’m new to EUC. With the high price tag of these EUC its concerning seeing plastic zip ties inside the motors especially when you hear issues with the motors failing. I’m sure there’s a better way of securing the motor wires. Plastic zip ties will eventually get brittle and shatter.
Thanks guys ✌️
Very informative.
The structure is fascinating.
Many parts hanging off other parts, that will be putting a lot of stress on certain bolt points. Also areas already worn from friction, and there were metal flakes from the screw removal.
Hopefully Leaperkim will address the issues in this prototype and nail the final version.
It's by far the most expensive 100v wheel and every part should reflect that in the quality.
(I'm sure that Leaperkim has a plaque on the wall that reads 'Remember the Abrams...'
Great job on the teardown, looking forward for your stress test video.
Thank you for bringing detailed information to me who is planning New Sherman. This video definitely needs to be checked by many riders.🙂❤️
Looks like a maintenance free suspension. Exactly what I'm looking for! Thanks for this tear down
Such a well done breakdown. Great work guys. Thank you.
Thanks for watching!
Great informative video. Lighting in the new shop looks great.
Excellent teardown!
And very informative.
Albert is very knowledgeable about these things.....and explains things so well!
Eevee's videos will undoubtedly make sales soar! And I am glad the manufacturer is listening to you!
You tore it down...now tear it up! Looking forward to Monday's video. Thx!
Loving the content!
Thank you for this teardown. Hopefully Leaperkim will release a more efficient video to get to the tire. Looking forward to the V13 teardown (if there will be one)
Good job, thanks.
If they give it even an IPX4 rating this will be perfect.
👍🏻-Thumbs up for leading the industry.
Congrats on 5K!!
👏 👏 👏 Thanks for this 😊😊😊
Could you please ask LeaperKim about the two shocks working independently and potentially twisting or warping the chassis over time? This was a concern that Wrong Way brought forward in his video. Thanks
Fantastic video looks solid with a few minor tweaks required
GREAT video, you guys and wrooooooooooooooongway and Marty are really giving the community a ton of good info. Thank you, Thank you Thank you. btw: I love Canada.
Awesome video thanks guys ! My only concern is the battery wire connecting the packs together at the bottom. I wish they could find a way to relocate that wire towards the top end up by controller vs down where rocks could potentially hit
Good job on this
Cool design and time will tell if it will last. This is a preproduction wheel so the sealing could be different in production version. I like that they want they own way.
Its just Crazy to buy at that price 🤯
That tire change looks like a painnnnnn.
Great review guys. Thank you. Overall looks promising. Do wish EUC's would work on better/real gaskets. Drives me nuts on my other wheels...Begode, Kingsong, Veteran all.
Minor issues to improve,really... Still I hope they really do listen to you, guys.Good job, this effort you made showing the tear down is most desirable. Now, do you think getting rid of Sherman's legendary bars will hold up on this new device? This new wonder seems to be a little naked without them so to bear the brunt of further agression...And they added a real strong block sensation of stability I truly wish I won't miss in the model S. Not to mention rigidity and protection for this awesome new beast...!
Looks like a very beautiful horse who dumps a bit.🤣 thankx guys keep sending them feedback
Thanks for the transparency after this video i def wont be getting one no water proofing and using xt60 connectors bad pcb board placement no gaskets etc etc .... Come on Kawasaki,Honda or Suzuki get on to making EUC they would do well :)
Honestly, for that price I expected better quality. There was quite a bit of wear inside even though it has been used only for a couple days.
The water isolation is not great either and it's hard to change tire.
The pedal design isnt well thought either. And no smart BMS neither.
The front handle which was metal in Sherman seems plastic... Which would easily break in case of a crash.
Keep in mind, this is a pre-production model. Veteran is taking our feedback and making changes before going into production.
You want something to break to absorb the energy of a crash. Plastic parts that stick out are smart. They will be cheap and easy to replace.
It’s metal where it needs to be. So far so good.
@@darkstar4494 No, you don't want anything to break. Build a hard shell to take the blunt and outer rubber to absorb the shocks. Build a PVC plates for the battery packs and rubberized the outer shell.
@@eevees
Well, I hope so, but Im skeptical if they really will do work on it.
They might, they might not (hopeful not the later). But even so, it is possible that we get a "fixed" wheel only six months later.
I really hope they fix those problems, because imo compared to other EUCs or the max right now it shouldn't be 4100+ usd.
@@BigBoss-gb4cx I can’t think of a better teardown on any other new wheel. No major concerns. We just pointed out any possible negative we could find. Personally, the teardown has got me more excited about the reliability of the Sherman-S.
The fake bolts on the side remind me of the "off road" on the Abrams. I enjoyed the video it was quite informative the quality I wish was a bit better though for the price we are paying.
Great look at the wheel.
I am looking to get out of computer servicing, I really enjoyed working on my own wheels, let me know if you looking for a tech in the TO/GTA area. I can fix just about anything.
Cheers
So what were those siliconed cables in side the hub/motor? Also what goo if any would you use when reassembling the hub? Super informative video btw, thankl🙏🏻
Looks high quality. The cables behind the pedals are a little concerning, though.
Too bad kingsong didn't consult with a suspension company like Sherman did, 👍 total professionally done...
Now if we can get a suspension company design a mono arm suspension for an euc.... Easy access to the tire/motor...
All the more reason to have a tubeless tire...
GOAT WHEEL!!!
Nice
So far I like it more than Challenger - I really hate Challenger's design where battery is glued into the side panels, so if you wanna replace the side panels you have to replace the battery as well (this is nuts)
Well it's going to require a little work, but nothing like some of the other wheels currently out. A few tweaks and they could have a killer wheel.
Thanks for this video.
Since you've performed it on a preproduction model, you said a lot of things weren't final.
The wheel has been out for a while now, could you comment on the changes that were made for production?
Great question. To our surprise, they didn’t change anything.
Do the bearing have gear in them?
Looks like the shocks should be connected on the top as well. When you turn, you're going to be putting flex on it, and the top keeps it together, so you are making a big leverage spot. Looks good tho . I may just be over thinking it
Introduction complete.. Teardown complete... time for a speed and range test.
Speed test is happening today. Range test will come later.
Very interesting video.
I'm actually concerned about the friction between the lower part of suspension attached to the motor and the inner shell. Another person already reported the same problem.
I think it come from a suspension bending and the U form not being as stable as it should be.
What do you think ? Will it be problematic after 5000km? 10000?
Thanks
So no smart BMS and no quick tire change. The v13 seems to be the better wheel so far other than range.
Don't hold your breath, V13's suspension is mediocre that it was not even made it on the bullet points of their presentation.
Time will tell
Good point Wen a BMS needs to be standard practice on these. I wouldn't be concerned about tire change time taking the tire off and putting another on blows enough I would be less concerned about getting to it imo
🔥🔥🔥
With this new connector is it just power going into the control board? No bms communication ? 😰
19:55 Does that rubber seal really prevent water from getting into the motor? It looks quite loose.
What's the brand on that workbench?
I have a slight knock in my Suspension some play. Where should I start lol
Most of it looks good but the exposed wires at the bottom underneath the foot plates like wtf?!
Can you please imagine yourself changing a tyre on that? Because I can't... 😉
Nice. Looks like a finished product, and not like a bunch of stuff picked from whatever was laying in a garage and held together with duct tape
What is the purpose of rear lasers? I thought it was on front-as a visual speed warning to the rider.... and Is the kickstand better than the MasPro? You can literally do hand stand on the wheel (Vee did it)
Complicated tire change doesn't bother me (yes there're many screws but they're just screws, everything seems to come apart easily)
But this custom pedal mount does bother me a lot. I like standardised things.
What battery cells does it have?
What are the lasers for? I assume they are somehow functional and not just a sexy feature. Are the head and tail lights still easily replaceable like the OG Sherman's?
Seems like just better visability at night. They project red lines on the ground in a v shape behind you.
Good video I enjoy teardowns great stuff. I see my s22 box in the back lol. Like your new repair shop, you look busy.
is that the right way round?
Is the front handle bolt on? Can it be easily replaced? It looks like it will get snapped off in first crash.
Very easily replaced but we requested that they beef it up before going into production
The main thing that concerns me is the overall structure. Why not have a rigid suspension bridge instead of a convoluted structure connected with bolts? As far as plastic is concerned, if this was made of the polymer found in glocks I’d have now worries about it b
I need to change tube on my Sherman S --- going thru all these operations just to change tire or tube is ridiculous.
Wow, super complicated, i almost got an engineering degree after watching the video!
🤘🤙🧡
Only the teardown tells the full story of the build quality of the product. Be skepitcal of all the flashiness of its appearance.
I came to see the new shock system, but nothing shown. Why?
There’s not too much to it. We went over it a bit in our last video. It’s beefy and the best suspension system I’ve seen to date
would anybody please tell me where to buy a battery pack for a Sherman S ?
parts.eevees.com/search?q=Sherman+battery
8:25 fiberglass board would be much better instead plastic on battery side plates
someone said these have gyroscope that balances you sideways 🤔
Can anyone please send the wheel bearing size for the sherman s. Seems I need to replace it early got the bad batch.
Go with the SKF 6208 2RS
@@eevees Thank you so much for that! 🙂
Albert is megachad
pls guys lets push Linea and the peeps from leaperkim to make sherman S next batch higher voltage looks like the wheel is just dope.
as a sherman rider myself my only issue with the S is why stil 100V....... not getting higher voltage??????????
PLEASE LEAPERKIM MAKE THE S 134V... I wish they would give it more battery aswell but hey making the perfect wheel would be counterproductive just pls GIVE SHERMAN S HIGHER VOLTAGEEEEEEEEEEEEE and i will buy it
Good job Albert. More of his input please . Nice to see that gimmick taillight is just a plug in and easily replaced. Disappointing to see all those rub points that need to be clearanced. Philips screws anywhere on a wheel of this price point WTF? The trolley handle looks questionable. This looks ruff and unfinished definitely not a finished product
Correct. This is a pre-production version. Refinements will be made based on our feedback to Veteran for the production version.
What is the deal with everyone shipping knobby tires??
Do they even test these wheels themselves? Seems like a lot of points of negative you can see
Albert might be a Begode Spy 😂😂 jk.
I really think this wheel came with a underwhelming motor for its price considering other wheels.
Abrams on sale for $2621 CAD and it has a 3500W motor.
Sherman Max $3744 CAD and it has 2800W motor.
V12HT on sale for $2172 CAD and it has 2800W.
KS22 on sale for $2471 CAD with 3300W motor.
Master $3220 CAD with 3500W motor.
SHERMAN S( $3994preorder)$4497 CAD for 3000W motor???? idk man. Id wait for the next version with a more powerful motor. other then that tho, it seems like the ultimate wheel. perfect size wheel, perfect battery size, great looking suspension that's not clanky, over all seems great besides the small motor for over $4k.
You look like great expert. How much power has Abrams’ mainboard? Or Sherman Max one? KS22? How much power you got if connected 100 kW motor to V12HT mainboard?
@@maximlapshaev
I have no clue, i didnt say anything about mainboards. I know how many watts the motors are though lol.
@@HumbolSkitso motor power is zero without the mainboard. In fact it’s one device - the motor and the board. If there is not enough torque, that’s mainboard’s current limit as usual. If there is not enough speed, that is concerning Kv and battery voltage. IRL motor power of EUC means almost nothing. Torque and free spin speed mean much more. What’s more we don’t measure the torque, we just feel if it’s enough or not. We can measure speed and do that. We never say like “yesterday I made 5 kW on my Abrams”. We cannot measure it and compare to each other, completely useless number.
@@maximlapshaev
Ok i see your point. So in theory we could keep our same wheels and just upgrade our mainboards? And the result could be more performance with increases in speed and torque? I feel like the motors Wattage has to become a limiting factor at some point right? I wish i knew more about electronics, sadly i only know whats advertised. So in my head, 3500watts beats 3000W.
@@HumbolSkitso now you’re making some progress in understanding that stuff 😉 one motor can have more power if used with 100 volts battery and mainboard than with 84 volts gear. All known things about the Sherman S motor are: equal numbers of slots and poles to the original Shermans’ motor. So, the only thing that differs - is mainboard. They could use slightly more wires in phase windings, but there is really small room for improvements if basic configuration is the same. We can mark an electric motor as one with bigger power if we just improve its cooling. You can see how side covers of the new motor look like. They can deliver a bit more heat outside the motor with their edges in comparison with old ones. So we have almost the same motor with new mainboard with higher phase current limit. And new number of kilowatts. Testers say that the torque is great. Ok, I can see bigger phase current from mosfets to the motor in that statements. To the same old motor, you know🙂
like a good-cop, bad-cop routine... one guy trumps how good the wheel is followed by the other guy who says, well not really.
To me it’s a turd rolled in glitter
👍🏼
Well done boys but shame about the wheel... Too convoluted over engineered better luck next time
