Offtopic: new KS 16 incher next year! S16?

He's making a good point, this wheel has no shell! Just the suspension assembly and the battery pack boxes. Cool!

Damn @Jack King Songsaying all the right things on that livestream 126V is for more torque while keeping a high max speed. And the max speed could even be higher if KS didn't want the 70kph limit. $3300 MSRP at the moment.

Clear now, thanks! So this is a S18 on steroids with a lot of improvements, and a direct competitor to the Hero. NICE! (The name S20 seemed like it had a bigger tire/rim). I'd buy one already if it weren't for the price (and possibly torque considerations). Phew, tempting

King Song really did everything right with this wheel. Wow. (I just wish they would show real photos.) I'm confused about the tire size. The website says 2.75-14. Is that the same as all the "18 inch" wheels, or is this a bigger rim than the S18 etc?

I would say that this is ok. Reportedly, riding a Tesla (1000Wh) near full speed (50kph) from full to empty gives 20km range. So 45 km for 50kph average, starting at 94% (which is less than full, full would be something like 110% on paper as 100% is not at the full voltage) and going to 3X% (apparently), seems fair even for the huge Monster Pro battery. Wind resistance at high speed kills range like nothing. 50kph average and 78kph(!) max is fast. And he lost the range from not having charged to full and not riding down to the tiltback.

Pretty sure that's just a random spammer.

The trolley handle is in the front of the built in seat (built in seat!). It's definitely there.

The adjustable headlights are cool!

126V Can't wait to see how the board looks for that.

New manufacturer, exciting!!

I meant whether it is a completely independent company (never mind the suppliers might be the same) or if they maybe share production (e.g. same battery packs, assembled in the same place, something like that) if it was an amicable split.

@houseofjobWow, fantastic info, thank you! Where did you get it if I may ask Holy moly! That explains the tons of wheels coming from gotway - it's not just Gotway anymore! So Extreme Bull seems to be Veteran #2, so to speak. They really must have had some disagreements at Gotway how to manage their company (or, less dramatic, just had some different opinions). So the Hero is a new Begode/Gotway wheel, and the Commander is a new Extreme Bull wheel. Funny how it is quite similar to the Sherman, which is also a "we left from Gotway to build our own wheel" design! Exciting news! Do you know if this a hard split or two companies maybe using the same facilities/resources and it's like 1.5 companies in reality?

I wouldn't know about anything special with 126V as opposed to lower voltages. Gotway tried it (with the Nik I believe). *speculation* Probably with too small components, and they gave up on it because they couldn't get it to work with the small components. If the S20 is 126V, I expect KS to use the right, beefy components. *end speculation* Maybe it's just the right time for 126V. KS usually put a bit more engineering effort into their wheels, so maybe they just said "let's do this now" and put in the effort. You can have more motor windings for more torque, and the higher voltage allows you to keep the max speed you would usually lose from more windings without a voltage increase. It seems the idea behind higher voltages is to keep "enough" torque without the wheel becoming too "slow" then (whatever "enough" and "slow" means for the manufacturer). For example, there's the RS HT and HS. With a voltage increase, you could have a wheel with the torque of the HT and the max speed of the HS, instead of having to choose between the two. Apart from the lost flexibility of the battery configurations and a bit higher component costs, there really aren't any downsides to higher voltages, so why not

Not unique to this wheel, but I just love the pedal height!

Is it confirmed? This battery size could be 84V as well (twice that of the S18). Saying that just so people aren't disappointed if it turns out not to be 126V, but 84V. Higher voltage either gives you more top speed, or more torque with the same top speed, or you can distribute the improvement between both. It would be a 50% improvement (if it is 126V) over 84V (compared to 100V being a 20% improvement). - I would be surprised if KS go 126V before Gotway, but who knows... maybe the S20 really is 126V?

When you get it, look on the motor rim, at the motor serial number. C30 is speed, c38 is torque.

Another one! Somehow I get the impression Begode/Gotway/Extreme Bull are just flinging wheels (and brands) at the buyers and see what sticks. Is this an EX successor? RS successor? Will there be the inevitable HS version? Why do this and the Commander have to be different wheels, couldn't it be one model with 1800Wh or 2700Wh or 3600Wh battery? But I'm not complaining. Copying the KS suspension is an absolute no-brainer move! Anyways, this is actually very tempting, especially "super torque" Hoping the price is ok. That thing on its back is pretty cool. Acts a extra mudguard, stand, suspension protector. Oh no, now I like this wheel! It's not ugly enough that it would be a problem

I second @ShanesPlanet's response above. Don't worry too much If it charges to full voltage now, the batteries are in a good state now. That rules out battery damage. Just don't charge unattended (apparently that applies to every wheel now) and you're good. All these fires have overwhelmingly been 21700 type battery cells. The old 18650s that the V10(F) uses have never had any fire problems, and there is no real reason a fire would start just because the cells have had too low voltage before. So if it charges to 100% reliably, you have a good wheel! Just watch out for any unexplained behavior or change of behavior (that, again, applies to every wheel).

Not much to do. Check that it works (balances). Check that it charges to full voltage/100% battery. Pump up the tire. Enjoy (Apps are actually not that important, but you can download an app on your phone and connect it to the wheel. Everything should be pretty self-explanatory).

This is the right answer. You got a defective product. Get your money back or ask for a new wheel.

Commander and S20 added, even though these might be a bit in the future (at least the Commander). New entry at the top of the list with the Commander!

Really good point! The tire pressure can be crazy low but look totally ok when you're not standing on the wheel. So check yours, it's on the tire and should be something like 2.5 -3 bar (36-43 psi). You might just be running with an effectively flat tire. That would explain everything, no battery worries needed.

Hm so your weight is not the problem. Do you have a regular charger you can use instead of the quick charger? 0.3A seems a lot for "being finished". Anyways, if the battery is full enough = if the voltage is high enough, the battery cell balancing should happen regardless of a charger being plugged in or not. The "keep it in for a few hours" thing is only to make sure that the voltage is high enough for the balancing to happen. I don't believe your range problem has anything to do with battery balance anyways. I would open the wheel to see if both battery packs are connected to the wheel. If one wasn't, that might explain your bad range. You can also disconnect one pack (it can stay in, just unplug) and then the other to see how the wheel behaves with just that pack. This will give you info about each pack (whether it is ok). CAUTION, make sure to never connect two packs together (again, or if one was unplugged initially) unless you are sure they have the same voltage (like 0.1V close). The easiest way to be sure that the voltages are the same (after they might have diverged when the packs weren't always connected together) is to just charge the wheel to full with only one pack connected, disconnect it, connect the other pack, charge to full again, and then re-connect the first one to get back to normal (= both packs connected to the wheel). Provided the packs are ok, if they are not you'll see that one pack doesn't charge to the full voltage, so check for that. By the way, the fact that your wheel charges to >84V (full voltage) means all packs that are connected are ok (otherwise they wouldn't do that). So at least one of your packs (the connected one) or both of them (if they are both connected) are good.
