KingSong KS16 680Wh (Sweden)

27 posts in this topic

Posted (edited)

So I have a KS16 that has seen very little use. Never got around to learn how to ride, never got the hang of it really, and now it's been collecting dust since last year. It's the white 680 Wh version. Will post some pictures and more info if there is any interest. Still have the original packaging.

I might be interested, although I'm actually looking for the 840Wh -version (either the older KS16B/C or the new S-model). I could consider buying that for spare parts or to use as a "modding platform", but then the price would have to be relatively low. Probably you'll get better offers from other people :P  How much are you asking for it? 

Btw, if it has been sitting unused for that long, I hope you didn't charge the battery to full before leaving it... the cells degrade a lot faster with high voltage and/or high temperatures.

Batteries were left at maybe 75% over winter. Definitely not fully charged at any rate. Kept in the basement so perhaps 17C and dry conditions. I guess I could get some data from the app to confirm battery condition?

75% shouldn't be that bad, especially since the temperature isn't high, around 40% and low (but not freezing) temperature is apparently "optimal" for storing. High temperature + 100% charge can eat away over 1/3rd of the maximum capacity permanently in 3 months:

Temperature

Lead acid

at full charge

Nickel-based

at any charge

Lithium-ion (Li-cobalt)

40% charge

100% charge

0°C

25°C

40°C

60°C

97%

90%

62%

38%
(after 6 months)

99%

97%

95%

70%

98%

96%

85%

75%

94%

80%

65%

60%
(after 3 months)

Table 2: Estimated recoverable capacity when storing a battery for one year. Elevated temperature hastens permanent capacity loss. Depending on battery type, lithium-ion is also sensitive to charge levels.

Good to know. I keep the EUC in the garage at this point. Was a bit worried about possible moisture during the winter but that would probably have been an ideal storage at +10C.

Not anyway near Halmstad I'm afraid. About the price I'm not sure. What does the community think about this?

Can you post some photos up?  I think these 680 wh older units go for about 1200 euros when new?  So maybe for a used one in good condition with no warranty it might fetch about 700-900 euros?  People likely are eyeing the latest model, the KS16S, with the more powerful motor now.

Since nobody seems to have made any offers (although they might have via private messages), I'll get the ball rolling by offering 500€ + shipping. But, I doubt that 1) Bjorn is willing to sell at that low price and 2) even if he was, nobody else wouldn't go higher than my offer   ;)

I might be interested. At least it's not far (Gothenburg) :)

I'm sitting here all flagged out and not thinking straight, so I'll have to get back on the subject of price...

Well, I'm offering 5K SEK (about 518€) + shipping of course. It is not much higher than esaj, I know. I just want to have a bid out there.

I'll have to retract my offer. I've ordered a Rockwheel GT16, and expect it in a couple of weeks. Sorry about that, but I can't really defend buying another for a while.

hi @bjornhallberg , the wheel seems in very good conditions, can you tell me its maximum speed of cruise and the real weight?

Good photos, I would want to buy it if it was not so far away.  One thing caught my eye, (the one that works) is, the cutouts are missing on one side of the shell.  I don't know much about Kingsong, but I do know they all play music through speakers.  I'm guessing this one has the two speakers, and not the four speakers.  It would not matter to me at all, just noticed the grill openings.  Makes me wonder if they are for speakers or air flow to cool the wheel.  Edit: great photos, very sharp and clear!

Not sure if I understood right what you meant by the cutouts, but if it was the speaker (I think) grills, if you look at the last two photos before the app-screenshots, they're taken from different sides of the wheel (look at the charge port cover, it's on opposite sides between the pictures). The pedal obscures the grills in some of the other pics.

Edit:  @bjornhallberg  Sorry, but I have to withdraw my offer too. I got offered a similar used wheel (KS16B / 680Wh) privately a little after that, and took the offer. It's already on its way here. Unfortunately, I don't need a third KS16 ;)  Still, I'd expect you'd get it sold, the summer's just starting...

I did not see that, thanks.  But it still means that only two speaker grills are open, one front and one rear. Right front and left rear?

Ah, you're right, never really paid attention to that... looking at my KS16S, it's the same there (it uses the same shells).

That seems like a good stereo, with the front and back and side to side separation of the sound!

@steve454 as I understand it the new KS14D has four speakers, while the KS16 makes do with two. No idea why Kingsong chose to have less in their bigger wheel?

hi @bjornhallberg 

can you tell me the real maximum speed of cruise and the real weight?

( I don't understand well from specifications, they talk of tilt-back to 20 km / h, and the net weight 17,1 kg ...I don't know if it is all correct )

@LEO_LEO KS is limiting the wheel until you reach the 100km-mark, until then the max is around 20kmh, then you can up it to 30kmh or so. There's supposed to be somekind of code you can use to bypass the limitation, meant for more experienced riders.
