Popular Post DjPanJan Posted April 6, 2022 Popular Post Share Posted April 6, 2022 @bkw @dangasaur Thank you and others for feedback. I live in Beskydy mountains area is realy hilly area canot comparable to New York ETC. PSI i recomended 28Psi 24-28 if you have kenda knobby tire. Is great mix confort stability and nimblenes. 16x is great mountainclimber i agree i own one. Mystery is MAX new motor have biger magnets or is just same magnets and increased power via Firmware or board electronic setup for biger curent this is what i want know before buy. Vanila sherman have power too but inclines is weakpoint specialy slow speed inclining. When rider take momentum vanila sherman have good results inclining. Nothing bad sherman is city cruiser by default and fact range with my 110+kg weight i can reach 100km distance normaly (max speed i have limited to 42km/h(26miles)) 4 Quote Link to comment Share on other sites More sharing options...

I lived in Bielsko-Biała Poland for a year which I believe is in the same mountain range. I'll try to make a point to do some long hills and let you know. The only thing I have to compare to is my V11 though. 2 Quote Link to comment Share on other sites More sharing options...

Pargame Posted April 6, 2022 Share Posted April 6, 2022 Hello, I am French and I use google translate. I ordered a shermax which should arrive next July. in france no one has a shermax suddenly I was wondering if one of you can given are felt, why so little enthusiasm for this wheel? for the moment we have no review but I wonder what is worth compared to the original. for info I canceled my pre-order of the S20 for this shermax, I hope I made the right choice 👍 looking forward to reading you US friends 2 Quote Link to comment Share on other sites More sharing options...
Popular Post littlebigmac Posted April 7, 2022 Popular Post Share Posted April 7, 2022 135 miles on my Max since Saturday, and I’ve got to say, this wheel is amazing! Absolutely limitless power when accelerating, uphill, downhill, braking, you name it! I’ve readjusted my Grizzla pads several times to get them in the perfect spots and they are definitely the best pads I’ve tried (compared to Clark pads and the stock Sherman pads). The Grizzlas allow for a much higher degree of control and stability because of how much support they provide against my legs when accelerating or braking hard, or while carving aggressively. With the stock Sherman pads I felt much less stable and my overall sense of control and maneuverability was significantly reduced. I’ve experimented with all three ride modes before settling on “soft”, which seems to allow for more effortless acceleration and braking, at the expense of instantaneous responsiveness (if that makes sense). I know the merits of each ride mode have been debated at length, and honestly it just comes down to personal preference but this is what works best for me. I’ve also settled on a pedal tilt angle of -2, which makes acceleration a bit easier and reduces foot/leg fatigue during longer rides (at least for me). I haven’t ridden the OG Sherman but I feel like the Max has plenty of torque even at slow speeds and up steep hills as well as plenty of headroom for quick acceleration even when cruising in the 35-40 mph range (40 being the fastest I’ve been willing to go for the time being). And finally, I rescind my earlier concerns about pedal dipping. Yes, the pedals do change angles after performing tight turns. But my muscle memory has already adapted to the point where I don’t even notice anymore and there’s no impact on ride quality. The more I ride and get comfortable with this wheel, the better it gets! While I still haven’t reached the level of familiarity and effortlessness I felt on the 16x, I’ve definitely gotten used to the weight and can feel the maneuverability gap between the two wheels closing as I get more comfortable throwing the weight around and pushing it into tighter turns. 10 Quote Link to comment Share on other sites More sharing options...

Rawnei Posted April 8, 2022 Share Posted April 8, 2022 Interesting, seems the motor is the same more or less, just thicker cables and software tuning that gives it the upgraded torque. 1 Quote Link to comment Share on other sites More sharing options...
meepmeepmayer Posted April 8, 2022 Share Posted April 8, 2022 (edited) The board looks neat. No crooked capacitors as usual, all nice and orderly. The Gorilla tape on the batteries and the so-so motor cable are things that could probably be implemented a bit nicer.

We would need to count the windings and measure magnets to be sure that it's the same. Small changes in both of those will yield real differences. Would be easier if LK just told us the specs of both motors. Quote Link to comment Share on other sites More sharing options...

Rawnei Posted April 9, 2022 Share Posted April 9, 2022 I wonder how the "low RPM over-current protection" works on the Max, what is the behavior and in which scenarios will it trigger? Will it just cut-off, will there be beeps to warn you before that happens? Quote Link to comment Share on other sites More sharing options...

Wheels normally have an overcurrent protection at some ?200A? phase current (120 in earlier days) - this works by just shutting the mosfets off prematurely during a pem duty cycle once this current is reached. Once this limit is reached it can be heard by the "metallic, creaking" noise.o For low speed protection there should be some additional protection in place to prevent components overheating. Like just either a lower phase current limit or some "softer mode" with less max current. in a perfect world could be some power dissipation simulation in firmware regulating the allowable current.... ps.: Could be that for starting/very low speeds and "normal" driving different motor driving algorithms are needed and the low speed algorithm just has some lower current limit...

Ultimately will it prevent boards from burning under heavy stress? Like on OG Sherman, I'm thinking long steep climbs. Quote Link to comment Share on other sites More sharing options...

Forwardnbak Posted April 9, 2022 Share Posted April 9, 2022 Pretty bad leaving dealers without support though, makes it tough for the whole game. Hopefully just a covid flow on with low or poor staffing Quote Link to comment Share on other sites More sharing options...
Chriull Posted April 9, 2022 Share Posted April 9, 2022 47 minutes ago, Rawnei said: Ultimately will it prevent boards from burning under heavy stress? Likely from short time peaks. Looking at the teardown pics the battery wires are still soldered directly beside the blank capacitor legs. There were pictores of veteran boards burned with a big black hole exactly around this area... Why are the capacitors in a thick heatshrink - to secure them from free moving unsoldered wires with melting insulations? The thick heatshrink hinders the capacitors from getting rid of excess heat! The battery wires need to be attached with screws and secured with thermal sleeves... 47 minutes ago, Rawnei said: Like on OG Sherman, I'm thinking long steep climbs. The thermal pad for the mosfets shown in teardown looks quite thick - as @EcoDrift mentioned people plan replacimg it with al oxid ceramics. As this thermal pad could be the weak link overheating the mosfets on longer steep climbs. He states also that main power bus for the mosfets is not reinforced (some wheels motherboards have thick copper wires for this!) - could be a weak link, too. As there are, afai guess no 1 hour ago, Chriull said: power dissipation simulation in firmware regulating the allowable current.... manufacturers with their firmware limits can either make them a bit too conservative, letting the wheels survive (more) but riders complaining about lack of torque/performance or they choose less limits with some more wheels fried at longer high burdens...

Tawpie Posted April 10, 2022 Share Posted April 10, 2022 He says it happens when it's being ridden too and is trying to get it replaced by eWheels, they gave him a 30% chance that it was a firmware issue. Resolution with eWheels is still in process. I'm guessing they don't have replacements on hand ATM though. 1 Quote Link to comment Share on other sites More sharing options...

I also have the Max with about 21 miles -- I haven't rode it much since last week due to work and rain, rain, rain rain rain raaaiiinnnnnnn. I'm riding my 16X around doing food deliveries, which is great, but it'd be really awesome with more range on the Max. Before I do that though, I'd like to get used to the Max. I want to give more reviews here in the future 3 Quote Link to comment Share on other sites More sharing options...
Popular Post BKW Posted April 11, 2022 Popular Post Share Posted April 11, 2022 (edited) I put another 45 miles on the Max today. As my second impression, it is different than the first. I didn't touch the PSI this time. This wheel actually feels pretty darn nimble. I have zero issues turning it. I went in an empty lot and just spun in some circles, etc., and I'm tempted to say it is, or almost is, as nimble as the 16X -- whether that is possible or not, it feels pretty comparable in maneuverability. As last time, zero issues with torque and hills. I felt no bogging down going both fast and slow; I hear no creaking/grinding of the motor on the hills. I put the tilt back to 173.9(?)mph, which means basically "unlimited" mph before tilt, and I set the alarm at 36mph on the Sherman (I am not using any apps). I was literally riding on the road with cars passing up cars. This thing is fast with headroom to spare. It didn't feel like it was touching any speed ceiling and I was slowed only by Manhattan congestion, pedestrians and road rules. Unlike last time, my confidence is much higher on it and I am going in and out of traffic like I do on my 16X. Not sure the fastest speed I went, but it had to be close to or higher than 36mph as I was riding with traffic and passing up cars as well. Acceleration is great on this thing too. Even though I've only rode two different wheels before, I honestly think even an experienced rider with many wheels under their belt wouldn't have much negative to say about this wheel. If I find any negatives with this wheel I will be honest, but the only "negative" might be the weight? Not really a negative to me though. After 45 miles only 2 bars down of the 8 bars total, and I was riding pretty hard this time. Edited April 11, 2022 by bkw 2 2 Quote Link to comment Share on other sites More sharing options...
Pargame Posted April 11, 2022 Share Posted April 11, 2022 thank you for your return, I was wondering about the maneuverability, it comforts me in the choice I made of my order 👌 I was thinking about the V12HT so I was frustrated not to see any feedback on the shermax 😆 Quote Link to comment Share on other sites More sharing options...
