I would say like everything, we get used to it, and it becomes less fun. I started EUC riding in 2016 with a Firewheel F528 that fried in two weeks, but I already got the virus that headed me into years of joy, heading from 20kph EUCs to top 75kph EUCs. It has been my main mean of transportation until I got to 2021, where I switched back to bicycle for most of my city rides. I did ride some of the newer EUCs, Master, Sherman S..but not the very last ones as nobody around me invested in those. I still have a V12 that I ride about once a month with a friend, I use it sometimes to get to places, its always at least half charged. I get nostalgia from the beginning when I felt like I was flying on EUCs, with a sens of freedom like nothing else. Its become more of a and backup vehicle, that sits there looking at a past golden era. It is still a pleasure to ride, but nothing like before, I wouldn't get ride of my last EUC, but I've ridden less than 2k km in the past 2 years, while I have a total of more than 50k km of riding, giving you an idea of what I'm talking about. I still enjoy reading, watching others talk about new EUCs and adventures that I will never do again, I guess its just...life ?

Hello guys, Correct me if I'm wrong, but except from the NYC Kingsong S20 fire, no EUC with the 21700 LGM50LT where involved in a fire. It seems there is a confusion with the LGM50T used in the older V11, old RS, S18, Nikola 100V, MSP, first batch EX, first batch Monster PRO. To my knowledge, it is only the older LGM50T that were involved in most EUC fires reported. Of course it doesn't meen they are fireproof (no Li-ion cells are) but they seem to be safer than the older LGM50T cells, the datasheet seems to say that the LGM50LT are safer than the Samsung 50E for example. Regarding the datasheets, the LGM50T are rated at 7.3A max discharge at optimal temparature, while the LGM50LT are rated at 14.4A which is basically double. https://www.dnkpower.com/wp-content/uploads/2019/02/LG-INR21700-M50-Datasheet.pdf Maybe @Chriull @Marty Backe @mrelwood could confirm ?

Hi guys, My experience is the following : I used my V8 for more than 3 years and more than 14 000km, charged to full everyo 3 times at least. I had a sort of charge monitor where I could see voltage and amperage, I could definitely see something happening after the led turned green, like 0.09A until it fell under 0.06A which could be just the bluetooth and motherboard consumption. The voltage was always at 84.6V (there has always been a slight issue with the voltage on the app) it almost didn't move, I guess that regarding the number of cycles at least 350, if there were no cell balancing, there should be some sort of issue don't you think ? Regarding my V12, it "only" has a little over 2100km, battery packs at the beginning showed 100.3V (pack 1) and 100.2V (pack 2), now both show 100.2V. I still use a little device to monito what is happening, and with the begode 3A charger it stays at 0.2A for some time then dropps and shuts off under I would say 0.1A to 0.00A, I would say it does seem to show some sort of top passive balancing ? Like @mrelwood said I don't see a reason why Inmotion would be the only company out of all contenders, to not have passive cell balancing. It would likely mean that Inmotion EUCs would die earlier or burst into flames more often, which doesn't seem to be the case. From what I saw on the PCB of the BMS of the V8 and V12, there seems to be bleeding resistors that should be there for passive balancing. It is still a pitty that no EUC company (exept for Ninebot) has active cell balancing, but regarding recent EUCs going over 40k+ km with the same battery (e.g the V11 with 48k+ km for the Inmotion challenge) , I would say that passive cell balancing does work for riders who are aware of the "top balancing" thing, though it should definitely be indicated in big in the instruction manual !

Hello guys, I've recently contacted Inmotion about charging with other chargers than the stock 2.3A charger, because mine is fried. Inmotion told me its best not to use any other charger than stock, I know if seems a little dumb but what are your thoughts about that ? I would like to charge it with a 5A charger instead of the stock charger if possible all the time (it would mean a full charge in 3.5h), do you think Inmotion is just over cautious or are they right in saying not to use anything other than than the stock charger ? Is the stock charger any different from an original 3A "Begode" charger exept from the voltage, form factor and being fanless ? Thank you

Hello @DjPanJan thank you for your reply ! I tested a sherman V1 it doesn't have this issue. When the motor is not engaged, if I freespin the motor there is almost no vibration, its when the motor is on however if I make it freespin it doesnt make any noise or vibration, only when I'm riding on it. The tire is perfectly aligned and its the street tire so its probably not coming from there. I'm wondering if its not just the motor that is like that with its imperfection.

Absolutely correct, mounting the new control board was not easy. I have disassembled a lot of EUCs (KS, Begode, Leaperkim, Ninebot, Inmotion, Firewheel) and its in my top 2 of the most complex EUCs (On the other hand I think it is pretty well engineered). I think that someone who never did it or who is not sure of what he is doing should have their resseller handle it as your life might be at stake. It would be interesting to know how many new control boards have failed just after mounting it and how many when riding afterwards. For now, the V12 rides perfectly fine but going fast gives you that adrenaline peak because of the possible failure of the board !

Hi guys ! After 1700km with no issues with the original motherboard, we did a board swap with the board with new mosfets. The mosfets arrived slightly bent, we fixed them on the heatsink with some standard thermal paste. It has been ridden about 60km no issues so far, we did try top speed, jumps, hard acceleration and climbing a 35° inclimb. It was on original firmware than came with batch 2 V12, no firmware update so far. It is still quite annoying that despite the new board, there still remains a fear of having this new board fail (reason why the swap happened in the firsst place)..

Hello, I have a Veteran Sherman V2 which produces a high frequency vibration from 15 to 27kph, also much stronger when accelerating but it doesnt do it at high speed or very low speed. I'm wondering is it just a motor default, or something that has to do with axle nuts ? I've checked all screws exept axle nuts but it doesnt do a knocking sound. Thank you for your help

Hello guys ! I juste tested out the Begode EX20S C38 and here are a few things I can say. For the background I have tested other suspension EUCs (V11, EX, S18). - The algorithm is very smooth, one of the best I have tried out on a Begode wheel - The motor doesn't grind at all, it doesn't make any noise its on pair with the Inmotion V12 motor which is really great - Boot up sounds are different from what I was used to on RS & Commander, I would say nicer - On the road, it rides smoothly and with half rebound setting its absorbs every road imperfection with ease - Offroad, it absorbs evert bumbs like nothing was there, it really makes the ride much less tiring than with a non suspension EUC - It is very heavy (49kg) and not easy to lift - It seems top heavy and therefore does not handle very well at low speeds with the stock offraod tire - At speed its very stable - It is the best seated EUC I have ever tried, I can break quite easily, accelerating needs some effort though - You are very high up the ground, higher than the EX, V11 and V12 from my experience - The front headlight is bright but doesn't shine far, it does not blind people though - The tailight would look great if it actually worked..its kinda dim but on the model I tested it only blinks in purple - Pads are ok, they are usable - It seems a little faster than the Commander HT in our testing - Its a shame that it doesn't have a display as there is tons of space in front of the EX20S - When it came, it didn't take the charge because of an issue with the charge board for some reason Overall, I really enjoyed this EUC, its really meant for long comfortable rides cruising mostly in straight lines, I would not pick this EUC for busy urban areas as its tiring to turn with it even though its totally possible. Its size was not shocking to me but its weight is really something else. It has a great behavior overall, still some Begode QC issues though I hope to test the Master soon to be able to compare it to the EX20S

Hello, So I sent an email to ECODRIFT for clarification. I asked them if the V12 (so not the V8S but it is the Inmotion flagship so I would guess other EUCs would not have balancing if the V12 doesn't) has active or passive balancing. They confirmed to me that there is no balancing... I also sent an email to EVE Energy CO who makes the V12 battery for confirmation but they haven't replied yet, as for Inmotion I have been unable to get in touch with them. This is quite confusing because we got different answers.

Hello, Current V12 batteries are manufactured by EVE Energy CO which seems to be a reputable company like Litech is. Question is @Cecily Inmotion can you confirm that this BMS has passive or active cell balancing ?

@WaulnutI deleted the inmotion app several times, checked on different accounts and verifying the scv each time to be the owner. I also cleared cache. I can change parameters through EUC World for some reason...haven't tried darknessbot I haven't got iOs.

Hello, I have an issue with my V12. I can change all the settings through the screen, I used to be able to connect to the V12 via the app but now it connects but it doesn't display speed, battery and I can't access the settings. Anyone having this issue or has a solution ? Thank you

Hello guys, I used a V12 with over 800km on it, I encountered some speed bumps even at high speed (+50kph) it never failed. I'm not sure whats happening with some V12 but it is concerning, I'll be careful now until we know for sure what the issue is. Control board firmware is 1.5.0.

Hey ! Weped SS (+75mph) and Veteran Sherman (+50mph), two top of the line PEVs
