Not sure about the 100K RMB thing.

my guess is that the site is something like kickstarter.

This is really looking nice and I like the specs. I am still not sure if the ninebot fits my needs as it is heavy and big. I am fine with my 14", 9,2kg wheel (but I need a more powerful one). This IPS Zero could get very popular...

Looks great! Light weight, big pedals, and 800W -- not too bad B)  I hope they didn't just make it pretty on the outside but actually put in good batteries with a custom BMS that will not cut-off at higher speeds. Does it say something about tilt-back or safety?

Also, I rather like the 'rough' padding to keep my EUC stable between my legs and I hope the smooth surface of the zero doesn't lead to unstable rides?? This might be just fine though and something to get used to.

There is also little clearance between the road and the shell; I don't think it can 30+ degree inclines... Even with the Solowheel classic riders complained that in the Seattle hills sometimes the back of the shell hit the pavement when going down slow on a hill..

Don't know if it's the case with Zero, but at least I recall @Jason McNeil once saying that in the IPS he dismantled, the BMS was integrated into the mainboard. So it's specifically designed for the wheel, not some off-the-shelf bike BMS.

Yeah, I've dissected pretty much the entire IPS product range, all have the BMS embedded onto the control-board. Here's a picture of the CB on the IPS131/132, the charging connectors to the battery pack are shown on the lower & lower-right side of the image. 

I get the sense that IPS are pulling out all the stops with the Zero (except the name) & everything may be redesigned from the ground up here. Will consult my sales rep to see if they have the inside scoop.

Hello,

Following a discussion with IPS.  It seems that this new model will be available from middle of August onwards. Price is not known yet.

Yep, looks much like kickstarter. Apparently its just a teaser for a campaign not yet started. Looks pretty darn tempting :wub:

Dear blessed Chinese speaking colleagues: can you probably figure out the details? Like when it starts and if there is a way for oversees-non-Chinese-speaking-longnoses to participate? As I don't assume, the "free shipping" extends to Europe, can you find any hint regards int'l shipping?

30 degrees would mean 58% incline (slope), it's clearly a miscommunication? 30% incline are 17 degrees which, I guess, could be feasible?

The design is awesome indeed, yet I am always (more) concerned with simple practical questions. Many of them you have asked already, here are some more coming into my mind:  

Can we fit a trolley handle bar? 

Do we have light and what's the specs (lumen) of the front light? 

Is there any anti-theft mechanism? 

Im I the only one who would prefer to see a 16" wheel with similar specs? 

BTW, I can hardly see myself buying anything below 300Wh capacity, other than as a cheap extra device, or with changeable battery specifically for traveling.

I really like this wheel, but

Response from IPS Sales Contact:
  1. is each motor individually tested as other manufacturers are starting to do? /IPS: Yes, before we make production, every motor need tested by professional employee, please don't worry about this.

now I am worried

 

Edit: I am unable to get the extra 'Jason McNeil' text out of the post :/, after Response from IPS Sales Contact:

  1. Does the Zero have the BMS integrated into the control-board as all other IPS models have? /IPS: Yes, it does.

Does this mean the IPS is safe from BMS cut-off?

Can't say anything for sure before somebody tests it, but as the BMS has been specifically designed for the wheel, I'd expect that they have taken measures to prevent unnecessary shutdowns (ie. the voltage limits are really low and/or slow reacting, so that they don't cut out immediately if the voltage sags and allow short-term higher currents without protections triggering).

Details are that the fuse (yes, IPS are one of the few manufacturers to use fuses) is rated to 30A, meaning peak power to cut-out is set to 2016 watts.

This is the pre-release Chinese price. Once the shipping, taxes, small (;)) reseller markup are factored in, it will be closer to the $800 mark.

Pure quality! It looks absolute gorgeous. If only IPS marketing materials had the same standards...  IPS has come a long way from the 101 & the i200 products. 

This feels like what the Ninebot should have been—light, practical, cheap(ish), high-performance, extremely elegant...

Why would the Zero-260 and the Zero-340 have exactly the same weight?

My guess would be same amount of cells, but the 340Wh version has larger capacity cells... there seems to usually be very little weight difference between cells, even if their capacities are very different, a few grams per cell. Typical Li-Ion cell weighs around 45-50 grams, IIRC.

Assuming 32 cells (16S2P):

264Wh, 132Wh per pack:  132Wh/60V = 2.2Ah (2200mAh) cells

348Wh, 174Wh per pack: 174Wh/60V = 2.9Ah (2900mAh) cells

exactly my thoughts as well, the motors have different rated power 800W and 1000W.

Design is very good. But... Max speed 30 km/h is quite dangerous with this kind of body. All is tight, even small stone can block the wheel on the run. Like this:

And now imagine your flight.... ;)

 

For that sppeed I'd prefer old school design:

SKU202915-1.jpg

Also no front/back lights to drive in the dark, no retractable handle, no USB port, low height pedals and finally, for 14" price is around Ninebot E.

No good for me, sorry.
