Leaperkim Sherman L || Quick Look

[@mo_euc]

This wheel is a great step forward for long range high performance wheels. Please ask Leaperkim to make a smaller wheel, smaller than the Patton so we can enjoy the amazing quality in a smaller form factor.

[@grb1969]

For the love of God, YES!

[@Vesataeuc]

I'm looking for exactly the oposite. I want them to make a touring wheel 151v with 6000wh battery for long rids.

[@EclecticWizard6]

[@SlowJoe76]

I really Enjoy your detailed reviews.!!! THANKS!!

[@donj5532]

Good start. Nice Wheel. Thank you. ... I may be alone in this ... but ... I would like to see a 100-Volt version of this wheel. 4000-Watt-Hours divided by 100-Volts yields 40-Amp-Hours of Battery. Amp-Hours is where the range is at. ... I ride a Sherman-S. 100-Volts is enough for 95+% of riding situations. Most of us that ride are "not" racers, you-tubers, or big-time jumpers. Most of us just ride for the joy of riding. 100-Volts will get that done nicely and I would be glad for the extra 11% range increase over my Sherman-S as I routinely ride 55-to-60-miles at a time.

[@Dogo.R]

higher voltages are more efficent not less

[@94e88]

You can't divide the 4000Wh by the peak charge of 100.8v, the nominal voltage is used in capacity calculations. The 100v wheels are 86.4 volt nominal(24 series pack, 3.6V*24=86.4V), meaning the 4000Wh would come down to 46Ah, which is not possible with the 5Ah cells the industry uses. A 45Ah pack could be made, but it is hard to design a pack of this kind as it contains an odd number of parallel cells(45Ah/5AH=9 cells). 3600Wh pack is as close as you can get which is a 8 parallel (5Ah*8=40AH, 40Ah*86.4V=3456wh or 3600Wh when using china numbers).

[@UpcomingJedi]

I feel the same way but they are in it for stealing sales from the competition. Its just good business. Watch begode come out with a 170v wheel next month. All of a sudden, EVERYBODY has a Begode.

[@BlaineRush-b8h]

You have no idea how batteries work

[@boblatkey7160]

Well a battery either is listed in watt-hours, or it has amp hours based on its operating voltage and they are exactly the same thing! 😂😂😂😂😂 i've heard this line of reasoning before though, not sure where people are getting their mathematics all screwed up. I've been in the battery industry for 27 years now. So a lithium ion battery that operates at 100 V and has a capacity of 20 amp hours is the same thing as saying you have a battery that is 2000 W hours of capacity. They are the same thing.

[@Happyantix112]

Working without a hall sensor isn't a "feature" its safety and should be standard on all wheels. Hall sensor failures are rare but still a good piece of mind.

[@bookmark2846]

Looks to be a great wheel. Sad to see that it does not feature adjustable pedal height but at least it looks like the pedals are the same as the Lynx which would mean you can use the same aftermarket pedals for both as well as the lowering bracket. I'd rather have a tubed tire because tubeless requires higher tire pressure and high PSI requires more skill to manage wobbles.

[@boblatkey7160]

Dude I think you got it backwards. Tubeless tires absolutely do not require higher pressure. You could go under 20 psi and not have any issues at all as long as you're not hitting jumps or curbs. Running tubeless tires on my mountain bike on Rocky chunky stuff I run them at about 15 psi. On my Lynx I don't like high-pressure so I run at about 22 psi.

[@bookmark2846]

@@boblatkey7160 That was what I told. That is great that you can ride on 22psi! I've wanted to lower the pressure on my Lynx below recommended but was concerned about the the tire unseating. I'm assuming you are using tubeless on the Lynx as well. If you don't mind me asking, how much do you weigh?

[@boblatkey7160]

@@bookmark2846 you will have no issues running at that pressure just be careful if you're hitting jumps or sharp curbs for example. I'm 165 pounds. Have fun out there!

[@c4ristopher]

Looks like the wheel I've been waiting for. My longest trip I'd like to do is about 80 miles round trip and I think this would be able to let me do it, even as a heavier rider.

[@WillofNewZealand]

Thanks for saying rim diameter 14 inch, many countries measure tyres that way.

[@familytvbox5218]

14" - is a RIM size... And it has nothing to do with the countries! Measurement by the rim is a motorcycle thing, but bicycle wheels are measured by the tire on the rim. As for euc - it is stupid to do the measurements by the size of the rim, as you can put different tires, that can be 1-2 inches smaller on an external radius, so the wheel will feel completely different. So, if you do your measurement on the rim - then Kingsong 18XL is the same size wheel as Lynx, Kingsong S22, Sherman S/L and so on, as they all have 14" rim radius...

[@WillofNewZealand]

@@familytvbox5218 I try only buy tyres such as a 14 inch rim has a 14 inch tyre. I'm not a fan of for example a 20 inch tyre that may measure 21 and go on a 10 inch rim. I buy 14 inch tyres for my 14 inch rims. I buy 80 90 17 tyres for my 17 inch rim. I won't buy other tyre measuring systems if possible.

[@darrenboone4239]

@@official.electricdreams alright, thanks 🙂any idea if this uses the exact same motor as the Lynx? I have heard that it's "better" than the lynx motor, but it wasn't confirmed either way. Can you provide some insight?

@@official.electricdreams has a larger rim been mentioned to compete with the master pro v13 rim size category ? I have a Lynx and will stick with my wheel. It’s so close to the Lynx. Sherman L and Lynx are Great wheels! So glad to see more compatible parts being used like pedals, headlights, and pedal hangers.

[@Redsun156]

Veteran Lynx still more faster and lighter than this specially if you’re using street tire on Lynx. Sherman L is bit more long range.

[@arevee9429]

Thank you, Jack. It would be nice not to need a decoder ring for changing the settings using the screen. An IOS app that had some functionality might help. I wouldn't buy this wheel because I don't need the extra range and the weight penalty that goes along with it. But the Lynx would be nice - even with the awful on-screen settings.

[@BigORider]

Dunno about the speed assist but they recently updated the app which lets you adjust the settings easily

[@coquirobinson3025]

I agree on what many are saying have Leaperkim build smaller wheel, but for me I like range, unfortuntely the issue is the price especially with no accessories. But this might be my one exception we will see.

[@UpcomingJedi]

I would add it to my "fleet" of airwheel x3 's. So far it looks like its the one I "need" simply for the great range and i can go faster than 10 mph. Funny how fast I reach tilt back now. I can see this having initial bugs so im happy to wait till youtube stars like Hsiang and Wraaahng wey! have tested them. The weight isnt all that bad if you can lift a comparable sack of concrete. In any case it looks like the perfect one for me.

[@COBARHORSE1]

Im very interested in this wheel. Ill probably wait for the second production run to make my purchase. I think i would prefer the street tire that came on my Sherman Max, or perhaps a shinko 244.

[@mightywind]

I would be interested to hear your thoughts, comparing the Sherman L to the Lynx. Isn't this basically a long-range Lynx? I've been planning on purchasing a Lynx soon, but now I'm wondering if I'd be happier with the L. 🤷‍♂️ How do you think the additional 14 lbs with effect its trail riding? I'm coming from a V12, so either wheel will be a huge step up in power, range and suspension. But how do you think the L will do off-road?

[@boblatkey7160]

I went from a V12 to a Lynx. The Lynx is an absolutely awesome wheel. And I get about 60 miles of range out of it but it still absolutely rips off road and it is a total blast. If you want to do trail riding and other off-road adventures I believe the Sherman L is going to be way too heavy. That wheel is going to be long distance road trips. although it will probably do fine off-road, I just think a wheel that weighs roughly 105 pounds is just too much for trail riding.

[@liamventer]

I wonder if the acceleration assist feature will also be added to the Lynx, Assuming it would only need a firmware update to add it to the Lynx.

[@boblatkey7160]

It's already been done! And I can notice the difference!

[@saxtalia]

Great review! question: when you say 40% more torque, do you mean than the Sherman S or the Lynx? Also, what is the top speed? On the Lynx the faster I am able to squeeze it before it starts beeping like a maniac is 90 km\h. So, how much can you get from this new Sherman L? Thank you

[@necavenue]

Why is this feature important? Does the hall sensor fail often in these wheels?

[@W_1_3_7]

I learned that the Lynx EUC can operate without hall sensors without cutting out. Could you provide insights into the principles or technologies that enable this functionality? I'm interested in understanding the general approach behind this capability.

[@thetastefultoastie6077]

Have a look for "High Frequency Injection" The inductance of the motor coils vary with rotor position. You can inject/overlay an additional current waveform over the phase currents during normal operation to measure how the impedance is changing and from that determine the rotor position. There's more too it, but that's the gist of it, it's quite a rabbit hole. This added current waveform across the motor creates the buzzing sound at low RPM that you can hear in the video.

[@CBRoadster]

Can we vote for LK to make the top completely flat instead of slanted to the rear. It make seated riding much more difficult requiring an aftermarket wedge style seat. I vote the Kenda 262 to stay as an option.

[@grb1969]

{ tl;dr. Lamenting lack of a BMS upgrade for Sherman-S.} Introducing the Sherman-L, without first updating the Sherman-S is insulting to the existing customer base. How can we trust buying a newer version when the older version needs these same updates. I’ll gladly wait for the Sherman-S to be updated before I would consider the Sherman-L. Kingsong had to learn this lesson the hard way when they salvaged the S22 but did it insufficiently with both motherboard reliability and a still compromised roller-slider design. Glad to have waited, and still waiting for a wheel that’s designed to update and upgrade over its lifetime (of at least 10 years). Lynx is the closest we have to a wheel worthy of upgrade but the design is still not good enough for the price being asked. Otherwise, the Sherman-L is a good incremental evolution worthy of praise, maybe after a couple of years to see what happens. If Leaperkim doesn’t offer discounted (or free) BMS upgrades to the Sherman-S, how can we trust that the low-production count on the Sherman-L won’t result in a future of regret?

[@BlaineRush-b8h]

What are you smoking? This IS the upgrade to the Sherman S. What are you even asking them to do? To release a new BMS for the Sherman S, to sell as an individual part, where you then have to open your battery pack and unsolder wires to connect? Dangerous and difficult for the average person to do. Stupid comment

[@GenZyannd]

what's up with the Hall "sensor-less". I thought it allows you to safely come to a stop, but how are you able to ride still? I mean how does it know whether u r going forward or backward without the Hall sensor?

[@ryangross5446]

Leaperkim magic. Its all in the firmware, and obviously its not an easy thing to accomplish or inmotion would have done it ages ago since theyre so focused on safety. Its really impressive display of firmware knowledge and application

[@grb1969]

My simplistic understanding is that the Hall Sensor measures the positioning of the motor magnets so that current is applied at the optimal time. Without direct measurement, the approximate position can be determined be tracking the inductance and back-EMF in the firmware but this is not as accurate and results in lower performance (low torque). How exactly this is done I don’t know. I’m not an electronics nerd, so yes, it’s Magic to me too!

[@Onetazien]

"111 mile range" Seems more of a performance upgrade than more range over the S, slightly more range than a performance upgrade over the Lynx. I would probably get the same spec, lighter Lynx and carry the charger to extend my range indefinitely. Inmotion V14 is probably the best all around, performance wheel to get imo if the charger wasn't too massive to carry for extended range.

[@grb1969]

The RogerEUC charger seems like the perfect solution for extended range riding for the V14 and the Lynx. If I commuted 70+ miles each way, then definitely the Sherman-L would be the better choice.

[@Onetazien]

@@grb1969 70+ miles each way = 140+ miles both ways so you are averaging 5-10 mph on the Sherman L if possible until the battery dies which is poor for longevity. Carrying a charger is still the better option if you have the time.

[@tonynova4724]

Same

[@dnthmn117]

@@Onetazien similar thoughts for my use case. I carry the Roger Charger SC168 if I need extra range and the 88lb Lynx plus the 3 pound charger is less than a larger wheel. But I see this being great for consistent long range riders.

[@truthiscensored]

The Sherman L won't sell that good/many units. The vast majority of people is not about to but a $4,000 wheel every year and definitely not several $4,000 wheels in one year. The EUC community is very small. So the EUC makers are basically selling to the same small group of people every new wheel release and hope the people have a greed mentality to buy. People already have wheels to fit most their needs, they not going to keep spending $4000 on every new wheel

[@joshuajones6113]

I expect a lot of people who want more range out of their lynx or more torque out of their Sherman S will jump for this. That means good aftermarket prices on used wheels and only a small hit to those people looking to sidegrade. Personally I've been waiting for a wheel with these specs for awhile. Can't wait.
