I know everyone else is interested in the looks or the new voltage or the suspension or the adjustability of the thing but, as a Begode owner, I'm really interested by the battery monitoring. every bms has wires to the individual cells, it uses them for balancing. The s20 also has a mcu that reports them to the main unit, so we can see them on the app. Think Z10. 3 3 Quote Link to comment Share on other sites More sharing options...

What is the owner supposed to do? Replace the faulty battery? Un-solder/re-solder a battery replacement? The cell groups are numbered on the BMS circuit board. If one fails, one can either take it to an e-bike battery repair center or buy a new battery from KS. Replacing the cells is hardcore stuff, the ones that can do it themselves safely do not need to ask for guidance. But the big winner here is that with individual monitoring the user can react before the battery fails. 5 1 Quote Link to comment Share on other sites More sharing options...

If it is reported early, just when the cell balance starts to get worse, some proper charge cycles to get cells back into balance can help to prevent the death of the cell, wich would occur if unbalance is not known to the user. But yes, if its too late, then all the end user can do is replace the battery pack. Just replacing cells or cell groups is too dangerous for an end user. There might be companies experienced in that, i don't know one, though. 1 1 Quote Link to comment Share on other sites More sharing options...

This for me is the best feature this wheel brings to the game, I am not fast or anything, I have an s18 with 4p setup, I was happy with it, now I want the s20 a bit irrelevant, but maybe interesting. This is my 4p s18, I weight 85kgr, and the other is the latest RS19HS, he weights about 70. The slope is over 35 degrees. I have a trail tire on, so it helps, but it is still interesting to see the ability of the s18 in action compared to a strong wheel. I really hope their next release will be the s18 with smart bms and 4p. https://streamable.com/yz5p8s https://streamable.com/l5vajq Edited February 16, 2022 by enaon 1 1 Quote Link to comment Share on other sites More sharing options...

I can definitely agree with the guys in regards to the suspension of the Hero. Towards the very end of the day and most had gone their separate ways, Lukas brought out the Hero. I took her for a spin and yes, the suspension is WAY too squishy for my taste. It would make for an excellent street wheel for places where streets are badly maintained. Performance wise it felt like your typical gotway/begode. I wouldn't go with the Hero for my type of riding. The S20 will definitely be my next wheel. Looks like Mike Leahy thought the same about the Hero's suspension and that's after he pumped it up to max. "It feels Funny" To me it felt like Jello, weird I know. https://www.youtube.com/embed/xywM07w-TjE?start=613 Edited February 17, 2022 by 5Cauac 2 Quote Link to comment Share on other sites More sharing options...

Couldn't tell if it was jumped/bonked up the stairs or was there a narrow ramp at the side. Ha! Not me, I'll wait until I can trash my own copy. And get better in the air (I'm not a jumper, fear still rules). That was a #revrides person, not sure who though (kind of dark). There's a ~40° slope that he hits, so it's sort of a bonk but it's not a curb... more of a ramp-ish thing. Where he hit it it's taller than the pedals, maybe a bit taller than the axel. As you get closer to the camera position (me) the rise gets taller and he did that a couple of times, but we were gathering for the group picture and sort of got in the way so he had to go where the ramp was a bit shorter. Edited February 17, 2022 by Tawpie fix guesstimate of slope angle, it's not as steep as I think it is... I think (not measured) 1 Quote Link to comment Share on other sites More sharing options...
I_Must_Bust Posted February 18, 2022 Share Posted February 18, 2022 Really liking what I'm seeing so far from the S20. But that weight will give me trouble going up and down the stairs to my apartment. I wish there was a <=60lb ~40mph 18inch wheel -- basically the RS but minus the explosions.

Do you know someone with a Sherman you can try carrying (similar experience)? It's different from carrying a wheel with one arm because you have two handles and you also use your leg as leverage so it's not so very bad.

Popular Post supercurio Posted February 18, 2022 Popular Post Share Posted February 18, 2022 (edited) SpeedyFeet review. Note that Ian had tiltback at ~20% battery, most likely because the standard app was used to update the firmware instead of Soft Tuner (as seen in the video) As a result it might not have updated the BMS firmware as required. Pending confirmation, the range test result and low battery behavior are essentially invalid and should be discarded. Furthermore, Raphaël from Bonheur sur Seine told me he was informed that the current chargers output only 124V instead of 126V (reason unknown: could speculate on that) This explains why Ian starts at 93% battery. Raphaël's S20 was not ridable until both mainboard and BMS were updated. Inconvenient, but it avoided invalid range figures to get published I suppose.Edit: Ian / SpeedyFeet tried SoftTuner but there was failures flashing the BMS firmware.

Popular Post Wolverine Posted February 18, 2022 Popular Post Share Posted February 18, 2022 Finally, we are starting to get in-depth reviews. By fixing some minor quality issues and with small changes, this euc can easily be the king of electric unicycles. Yes, I know many are upset with the S20 weight and maybe also the size of the machine, but let`s be honest, what Kingsong has achieved is quite impressive. 6 Quote Link to comment Share on other sites More sharing options...
