Fahrtwind Posted July 28, 2015 Share Posted July 28, 2015 (edited) 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...

Daan Posted July 28, 2015 Share Posted July 28, 2015 (edited) Looks great! Light weight, big pedals, and 800W -- not too bad 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..

esaj Posted July 28, 2015 Share Posted July 28, 2015 (edited) 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.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. Edited July 28, 2015 by esaj Quote Link to comment Share on other sites More sharing options...
Jason McNeil Posted July 28, 2015 Share Posted July 28, 2015 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. 3 Quote Link to comment Share on other sites More sharing options...
Gabriel Posted August 2, 2015 Share Posted August 2, 2015 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. Quote Link to comment Share on other sites More sharing options...
Tilmann Posted August 2, 2015 Share Posted August 2, 2015 Yep, looks much like kickstarter. Apparently its just a teaser for a campaign not yet started. Looks pretty darn tempting 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? Quote Link to comment Share on other sites More sharing options...
Popular Post Jason McNeil Posted August 4, 2015 Popular Post Share Posted August 4, 2015 We, WheelGo.com, have been the main European IPS distributor for about a year and half. The early IPS products, like the original 101, i200, & 111, had some pretty significant flaws but since 2012 (IPS were 2nd in the eWheel game, releasing their first product only a matter of months after Solowheel) their products have been progressively achieving a higher quality standards. In contrast to Airwheel, IPS have concentrated on single-wheel products, offering a range of eWheels with some decent specifications & performance. Historically they've taken their technical design philosophy from Solowheel, believing sub-20kph & pedal-tilt-back programming key to preventing over-speed cut-outs, at price that's about half that of the Solowheel S300/classic but with double the range. The IPS Zero is a departure from this conservatism, it will be interesting to see if the quality of the Zero holds up to the expectations. There have been so many disappointments with eWheels with high expectations in the past—witness Fastwheel Eva (pretty rubbish), Ninebot One (@14.2kg not very practical), WindRider (see FB thread...), that the odds of a perfect 30kph, sub-10kg eWheel, is very far from certain. That said, IPS do have the experience & resources to deliver on this ambitious design, only time will tell.... Below are some questions I put to my sales rep about the Zero & their responses.Response from IPS Sales Contact: The news about the new IPS Zero is getting a lot of attention on the Electric Unicycle forums. Would you be in a position to forward these questions to the engineering team? /IPS:Of course, thanks very much for your support. Until very recently IPS had considered going above 20kph a bit risky & prone to motor cut-outs. What have IPS done to minimize this risk? /IPS: Now the top speed of our unicycle is 30km/h, customers can adjust the top speed(15-30km) when riding about 50-100km, in order to protect customer's safe.Does the pedal-tilt-back prevent the user from riding beyond 30kph speed? /IPS: when the speed arrive about 24kpm, the pedal begin remind rider. The appearance of the Zero is breath-taking. Did IPS employ a famous designer to design the eWheel? /IPS: Haha, it's also our designer.There are some who say that it has many similarities in appearance to the Ninebot One. What does IPS have to say about this? /IPS: Every brand has it's characteristic, we are design the products according to the market demand.At the moment, the specifications are built around a 132Wh & 260Wh versions. The higher capacity version must contain 32 cells, with higher capacity cells, it should be able to reach 350Wh & beyond. Are there plans to also release a higher capacity version as well? /IPS: the capacity version of Zero contain 32 cells, if there is a demand for 350wh, we can make production, but in high quantities.Does the Zero have the BMS integrated into the control-board as all other IPS models have? /IPS: Yes, it does.The 800W power rating, is this the sustained power specification? /IPS: Yes, it is.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.How many hours of testing & QA have gone into the development of the Zero? /IPS: It's a long time, zero has tested 3 times, every time, when the sample is ready, our technical will test it and find the problem and then solve the problem, we all want make a different product for customers. 8 Quote Link to comment Share on other sites More sharing options...

Mono Posted August 4, 2015 Share Posted August 4, 2015 (edited) 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.

cg Posted August 4, 2015 Share Posted August 4, 2015 (edited) I really like this wheel, butResponse from IPS Sales Contact: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: Edited August 4, 2015 by cg Attemting to fix foobar layout 1 Quote Link to comment Share on other sites More sharing options...
Daan Posted August 4, 2015 Share Posted August 4, 2015 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? Quote Link to comment Share on other sites More sharing options...
esaj Posted August 4, 2015 Share Posted August 4, 2015 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).

Jason McNeil Posted August 6, 2015 Share Posted August 6, 2015 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. 1 Quote Link to comment Share on other sites More sharing options...
bleu9mm Posted August 7, 2015 Share Posted August 7, 2015 At $400, it's gonna be one big contender for Ninebot one... Quote Link to comment Share on other sites More sharing options...
Jason McNeil Posted August 7, 2015 Share Posted August 7, 2015 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. Quote Link to comment Share on other sites More sharing options...

Jason McNeil Posted August 7, 2015 Share Posted August 7, 2015 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...

Mono Posted August 7, 2015 Share Posted August 7, 2015 Why would the Zero-260 and the Zero-340 have exactly the same weight? Quote Link to comment Share on other sites More sharing options...
esaj Posted August 8, 2015 Share Posted August 8, 2015 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) cells348Wh, 174Wh per pack: 174Wh/60V = 2.9Ah (2900mAh) cells 2 Quote Link to comment Share on other sites More sharing options...
Gabriel Posted August 8, 2015 Share Posted August 8, 2015 Why would the Zero-260 and the Zero-340 have exactly the same weight? exactly my thoughts as well, the motors have different rated power 800W and 1000W. Quote Link to comment Share on other sites More sharing options...
vag72 Posted August 9, 2015 Share Posted August 9, 2015 (edited) 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: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. Edited August 9, 2015 by vag72 Quote Link to comment Share on other sites More sharing options...
