  2. Ok, tested idling for about 15 minutes to raise the temperature to 65°C, which produced an audible alert (continuous periodic single beep), continued on to 71°C. On this early version of firmware, 1.07, you can continue to rock-back & forth without any extreme tilt-back, but as soon as you move in a forward direction, the 15° pedal incline is engaged. Tried downloading the updated firmware, however, the new 'beta' App can't connect to the backend server.

  3. You are the one who has direct contact with KS China and since you don't know, that kind of scares me. This is how I think SHOULD be: E.g. a clear procedure for control board temperature 1. 50C - the fan turns on; 2. 70C - sound warning; 3. 75C - soft tiltback; 4. 80C - hard tiltback. If we do not have similar procedure written in the factory instructions that means IMO two things: 1. Mere omission due to immature company marketing; 2. Keeping procedures intentionally in the "fog" in order always to have an option to avoid responsibility and blame t

  4. @bego1969, that is exactly the point and why BMS issues come up so much in this forum. To summerise what has been discussed in detail many times: In an electric vehicle other than a self balancing device the BMS has four distinct functions all of which are designed to protect the battery. 1) the BMS monitors each battery cell and ensures that all are held at the same voltage during charging (called "balancing"). 2) the BMS prevents any cell going above the maximum voltage (typically 4.2v for Lithium Ion & Lithium Polymer cells) 3) the BMS prevents excessive curren

  5. @Addwyn, what rotten luck, sorry to hear about the fall. Did KS France have any insights to offer—they've been using their early serial numbers for more than a month now? I've also reached out to Tina to see if there's been any internal theories about possible causes of the cut-out. Finally received our first KS16" this week & have been testing it out over the past couple days. The temperature here in Miami is well above 90°F (>+32°C) even after 8 miles stays below 50°C. I'm going to try recreating the over-heating condition to test that the behaviour is identical to the other mod

  8. @SlowMo, Yes, it could ! But as my wheel works absolutely normally otherwise and therefore there is no visible sign to permit to distinguish a defective mainboard from a well working mainboard, the problem would remain exactly the same for all of you : You can not know if you also have a "defective mainboard" or not ! So the risk stay present ... Personally I think your assumption is something like "please, make my wish to be the reality" That would be great if that was so simple. But I'm not concince that this is the reality.

  11. This could be a single issue of a defective mainboard and not the design in general. There is always some defective units in a batch. That is why there is always some warranty available to buyers. The bad thing is @Addwyn is the unlucky one. Wishing you a speedy recovery @Addwyn and hope that Kingsong make good tems with you.

  12. @Gunthor, You'r totally right. It's impossible for me to reopen the KS16 with one hand ! (and it's not easy to type with only one hand neither) @Henrik Olsen, In page 2 of this topic @Gunthor said that " The fan turns on at 50°C ". So, even with two operating hands, how to know if the fan is working well when needed ? In my opinion, a fan failure would not be a satisfactory explanation because in the case of a control board's overheat, whatever its cause, fan failure or not, the wheel should follow a safe emergency-slowdown protocol up to a total softstop... A fan failure could inde

  14. My wife bought a KS16 two weeks ago. After a short trip with a ? mark in her face we took it with us on a trip to France (Sundgau/ Alsace/ Elsass in the area around Ferrette. On the first day I rode it two km/ the second day all the time and it felt powerful. The motor/ MOSFET sound was harmonic. Maybe the shell amplifies a bit the sound. o the pros: it's very agile it's strong with 680 Wh well prepared. no problem to handle a heavy weight man with a back pack looks very well designed the cushion prevents bad feeling, but anyway via normal riding you've

  15. You do realize adjustable tilt back has been around already for awhile right? King song and Gotway both offer this along with level calibration and adjustable beep settings. This whole thing seems to come down to a lack of product research before buying, which I think OP now realizes. IPS is not a bad product, but for more demanding and particular customers (hey, I'm one of those too- I get it!) it doesn't make much sense to buy a wheel with no options.

  18. I just took my KS16 for an 11km ride, with some 1km long inclines... The incline was done with speeds between 22-24kph and I did not seem to change the temperature more than 1C... the wheel started out at 26C on leveled out around 47C... I'm +90kg and the ambient temp is around 18-20C... so far I can't make it overheat...

  21. It would be nice to see an option to pair the tilt-back function with the final alarm to serve as a precaution should the alarm buzzer fail or the rider can no longer hear it. The final alarm is variable, it depends on the battery level, therefore setting the tilt-back to a fixed speed won't be as reliable.

  24. I'm of the same mind as @Jeffrey Scott Will. It's my opinion that black as the primary color with any other color, save for maybe white, will make a design look cheap. And red accents can certainly be overpowering if not used conservatively in just the right places and with the just right shade. As such, I don't much like red as an accent color, but I do I think that red, black, and white can look very stylish together, with designs like this: Here they have red is the primary color with white as a secondary color that gives the red a breath of fresh air. The black is reserved as an

  27. My Firewheel turns the power on when the power-pins are NOT shorted, so it still uses a latching button, but even in case the button would come unconnected during riding, it doesn't turn off the power. At first I thought that was weird (kinda like the opposite of what you'd expect), but I get that it's a safety issue. On the other hand, I think my generic (cannot check now, as it has been on loan with my father-in-law since last summer) has a simple latching push-button, that could cut the power if it became unlatched during riding. The problem is that the braking power has

  33. There's simply no comparison. Hoverboards are terrible. Not even fit to lick the boots of the original Segway. Despite having an 'ok' top speed, you never see anyone doing anything more than a crawl on them because the tiny wheels combined with the wide perpendicular stance and the sudden turn mechanism means instant wipeout if you ever try and get some speed going for anything other than a really flat, really straight a to b movement. I almost feel they insult the original Segway, which was and still is a wonderful machine and great fun on euro tours etc. There's still a place for

English speakers will mainly use earth to refer to something grounded to mains power. While they will sometimes use ground to reference anything connected to the negative terminal of a battery.

First he complains that @Jason McNeil didn't state that this wheel didn't have Bluetooth (he didn't state that it didn't have lights and didn't have speakers either, why didn't he also "assume" they should have been there?). When not having Bluetooth that it was not advertised as not having wasn't enough then, suddenly, it doesn't ride like a Solowheel either. Well, as far as I understand, every wheel rides differently, how many times have you seen reviews make statements like: "after

Side note, I let it continue after charger LED (kingsong) went green, it took at least 2 hours to fully balance all cells best I can see. For best care I think a balance charge about every 15 charges or so is good. There is also a dongle to plot graph, but have not got around to understand it yet. UKJ Thanks H 16!
