    How to replace IPS I5 tire?

    Probably you are riding on a low pressure. I had to change once only and it happened when I did run on low pressure that I though it was enough. If you feel the wheel like moving sideways on rides, it's definitely on low. PS. Check the tire pressure weekly. As for changing the tire I used no tools (except to open the case). You simply need to align one side of the outer tube in the center of the rim, which makes room on the other side to slip (with slight force) over the rim. once you have one wall, the tube can go out easily. You only need to slip out one wall of the outer tire at a time. Same thing in reverse to slip the tube back in making sure you don't pinch the inner tube.

    IPS out of business now?

    IPS is not out of business. They sell mostly in China.

    IPS Zero: LED's broken

    Your first picture just loaded now (Was kind of impressed by the 400+views this post without a reply attracted) Do I see a black dot on the top red cable? can you check there is continuity there on that cable? Also the third clip (Always from top and actually all first 3) seems not to be fully inserted in the plug, can you see if you can push a bit the third cable in so it will align? I'm suspecting that the cables were not doing a good contact

    IPS Zero: LED's broken

    Hi @Nicholas, I'll try to get some details on your issue and get back to you. Since you reversed the connections you might have broken the LED strips but you need to test that. As your original problem I was thinking of a firmware update as I had encountered something similar before but you said after opening it which makes me think that a firmware update cannot be of help. Will get back to you when I get more details
  5. In my other post I explained a bit on how it should work. When you buy a product you buy it off the other end's hands, If the shipping was defective you deal with the shipping company which I don't know but assume is not, the shipping has to be paid as they delivered the goods and you accepted them. Shipping back will again request another service but (unless agreed before) shipping is customer's responsibility, not to mention the customs clearance issues to return it. If they had to allow returns, everyone will be importing goods as returns in China, faulting the import export strategy at a certain level. As regards to apogeebuy, they should be somewhere near my area but the address seems to be incomplete. At best you can try to call them (or ask the police to do so as I know put some pictures where you hinted that you filed a complaint in your state) on +86 177 8382 5663 (which I derived from their wechat account.) If they don't answer at least in Chinese, these are invalid and you want to break any hope with them you can always file a complain wilt ICANN with incorrect details which I read somewhere online that it will fault their website presence. This is my extent that I will help you out, sorry if I do your next public complain will be that I didn't. I truly believe that you're putting the IPS company name a bad image when they actually are trying to help you out outside their channels. The wheel you bought they sold it domestically not internationally. Only your ap**** tag here holds and you only posted communication with IPS and nothing with Ap****

    IPS S5

    @steve454 Yes, babies eat their parent's time (Esp when you're 24/7 with) so I'm not being here often and unfortunately rarely riding. Anyone needs the app though can send me a private message. @Randalab I'm sorry to read about your happenings. In my line of work I reach many disappointed customers on purchasing from abroad because most expect the same after sale as buying from a shop and forget the distance in between (its not easy to return a defective high valued product in China for several understandable reasons and you need to keep this in mind if you purchase a single product directly). Now in your case I think you have to take it against who you purchased it from (Quoting you po*******co). Ms. Yue from IPS in my opinion went out of her way to help you out and you still blame them. If you bought it directly from IPS she should have all the obligation to assist you, but since you bought it from another source you should talk to your supplier and if they think they should reach to IPS, your supplier should reach to IPS factory. If the large dealers are not working with IPS I doubt it is for quality but more for unreachable negotiation, unplanned future issues or irresponsible wrong information leaks and by quality I am not saying they have an always 100% good product out of the factory, but when they don't they do sort it out (which I call quality as trust me all factories have a defect by at least a minor one but not all admit and resolve them). Back to your case, trashing the image of a company you purchased for is making yourself loose the value of your purchased product when your issues get solved. If they don't respond timely does not mean they disappeared, again don't forget your distance and again it's not IPS's obligation to respond to you even though they know about some issues, their obligation is to send the resolutions to their direct buyers (dealers and single purchases directly from IPS). As for the shell, I didn't see the S5 but my last trades where on the I5 and I can understand why they don't sell shells separately. The ideal mounting of the shells need specific tools in my opinion. I hope you get your issues resolved though.

    Rent an EUC in Malta

    Hi @realbizkit and @littlelio. Sorry for the late reply. Yes we do rent EUCs. I am sending you a private message for more details.
  8. @TremF Well... how knows when and how the word spreads. Worth a try. I can't sign but I forwarded to the people I know who can.

    Did I destroy my battery?

    In my experience, some cycles might help for the next couple of rides but you don't need to drain it down all the way, at least charge IMMEDIATELY after the first low battery warning signal and DON'T PUSH IT FURTHER. It was my first Chinese generic one which came new without any battery charge (I wish I had more knowledge to return it back). What I also noticed though is that first, it improves the range (after the first 2/3 cycles) then soon after distance was fairly reduced and some cells seemed to got shorted a few months after, after storing it for a couple of weeks more later. To my understanding, those 2 cells probably got a higher resistance and got over-discharged during that storage time but battery life was evident to have come near the end of life before storing it. PS. that battery only lasted a year for me As @WARPed1701D and @Keith suggested check the charging voltage first but be very careful if you see a pattern like mine. Getting 2 shorted cells at the end and the battery was not fully charging (I remember both chargers I had for this wheel were switching red-green continuously) and got me hurt at slow launch. I would rather look for a new wheel or change the battery if so (after some tests to make sure the battery only is the issue). For charging time you can check the manual, but a few hours is normally required. Also, protection gear (Minimum; Helmet& wristguard Then; Elbow and knee pads) is suggested for trying it out with such a battery.

    IPS Zero: 30A Fuse blows

    @Rol did you manage to get some investigation done on your problem?

    IPS Zero: 30A Fuse blows

    @Rol I reached IPS and the person assisting us just came back to the office. you can test both the motor and the board to find out where the problem is. The fuse you know how to check and you know it is getting broken. For the sake of others, I will write it anyway. Fuse test: Disconnect all the board wires completely from LED lights, motor and battery, open the control board box and locate the fuse. The fuse resistance should be less than 1Ω MosFET Test: You will need to test 12 Mosfets as follows (At this point the document they sent to me is a bit misleading so I am quoting as they say in their document with my suggestions in brackets) common or ground (-ve black probe) on the middle leg and +ve (red) on the left and right leg. record each resistance for the 12 fets i.e. 24 tests (due to polarity they request I think you need to find the voltage drop of each using the diode setup) Connect the +ve (red) to the left leg and -ve (black) to the right leg and record the last 12 resistances (again due to polarity they request I think you need to find the voltage drop of each using the diode setup) All recorded resistances should be similar and all high values of several Ohms (or I believe you should find no shorts) MosFET Diagram with PCB Behind FET for spoon feeding orientation |----------|------ Right | FET |------ Middle |______|------ Left Motor Test: With the motor disconnected, set the multimeter to Diode mode (this is a bit misleading for several reasons here too so will take it the same as the above) connect the +ve (Red) probe to the black wire and connect the -ve (black) probe to the green yellow and blue lines (do them for the 6/7 as I am not sure it's the Haltzer sensors wires or motor cables and about that red cable in pictures). You should read a voltage drop of around 0.7v their picture shows 0.602 on the hall sensor connection only not power cables Connect the -ve (Black) probe to the same black wire and connect the +ve (red) probe to the red green blue lines (again I don't know if its the power or hall lines, if the above is hall sensors then this might be the power lines but that's my assumption on the power lines not being tested) You should get a 0 of no resistance on the multimeter at this point. this is my point. While at it check to have same resistance on yellow-green, green-blue, blue to yellow I presume it should be. Once you do all the tests above kindly report the findings and results here before any conclusions as I have some assumptions and I don't have a Zero to check on ATM. Start off with the motor test... that's the easiest with no need to opening the control board

    IPS i5 foot angle experiences

    I rode more than 20km on it and with a slim tire on high pressure is more concerning for comfortable ride, but it performs very well. The earlier versions of the i5 were probably more sloped to my knowledge but IPS tuned their design accordingly. The 20km is a limit imposed by the firmware for safety. IPS went for higher speeds on the s5 that has more redundancy. the warning beep goes on before the 20 of course. One time in SZ, I encountered a guy on an inmotion. He was cruising on the street but managed to keep up with a lot of beeping from the curb. if he wanted to run i wouldn't keep up but the limit is fine for normal commuting. I don't like going beyond the beeps, I feel it is an unnecessary risk to gain a few seconds on the journey

    IPS Zero: 30A Fuse blows

    Hi guys, I just returned to China from some long busy travelling. I will get in touch with IPS to have more knowledge on the error code while also reading deeper in the thread as I just skimmed through. Will get back to you shortly.

    Any way to contact a rep at this company!!!???

    I had a reply from IPS. There is only an Android APK for your situation. I guess you will need to get hold of an android phone with Bluetooth. If you are a programmer maybe you can try to do it in some Android Emulator on our Apple Product that talks to the BT directly but I do not know if this is a doable thing and there's more risk on it. It's easier to find a friend on Android to help you out.

    Any way to contact a rep at this company!!!???

    Sorry for the late reply, I was travelling recently on some projects and will be back in China early July. I will relay the message to them, though there is a leaked solution on this forum that involves re-flashing the board using an Android APK. Assuming everything is fine with your wheel and you put the right SN and parameter to the application that should work fine but you will be doing it at your own risk and I cannot accept responsibility for flashing it wrong or failing at reflashing. I'll try to link to the post later @Medialab Thanks, @Keith for the attempted alert

    Ips 122 260t app control

    Hi @Ipsiain, There are different models for the LHOTZ. The later models I dealt with work with the last 2 apps designed by IPS and have the soft and sports mode. A speed adjustment won't strictly speaking limit the riding speed but more at which speed the tilt back and warnings kick in. It is also possible that the over speed margin changes but as always suggested, never ride beyond the set speed limit and respect all warnings. They avoid cutting off the power at the speed limit, and on the i5 I think (from memory) it cuts off at around 35-40km/hr (At no load. i.e. lifting it up) where its speed limit is 20km/hr. In one meeting I had with IPS I was also understood that cutoff also considers the current so a no-load will be considered in the algorithm. Did you try the APP from IAMIPS ?

    Malta Electric Unicycle Meetup

    @9botter not much... 4 maybe. But now I'm staying in heaven.... China now I will be in Malta around end of May for a month so maybe we can meet and go around (hoping my wheels are still in good shape back there)
  18. Anyone rides the Electric Unicycle in Malta. I ride one often but still I haven't seen anyone around. Would be great if we can meet up and plan some route. If anyone is interested (even without an EUC) please post below, I have a few ones here

    IPS 122 tilt forward on acceleration

    On a BT version of IPS, you can check the Voltages of each cell individually from the APP. You have like a matrix of 4x4 (16 cells) with separate voltages, so that was no big deal. One reason for being so close is that my i5 is not that old, but even on my LHOTZ and Zero there were very close. When I get back to my country I will check on them as they might differ after a long time not having proper battery cycles and will keep you guys updated on 8 months rest would result in them.

    IPS 122 tilt forward on acceleration

    I checked on my IPS i5 (i don't think they changed the logic of the BMS much) but on a full charge from like 5days ago batteries on the app show 4.08 and 4.09v on all cells (20700 not 18650 but since they are on same chemistry I assume same voltages). I don't think there's an easy way to build a temporary battery without welding them. At best see that you can raise individually the voltages of the cells to 4.05 at least. if you're using an RC charger, that should stop if they are not taking enough current (meaning full) if that's the case on a lower than 4.02v, that cell is very degraded and most likely the cause. If I get to this stage personally I would build the new battery as you already had dead cells, some would have been identified as aged batteries, the rest won't last long and you will have to open again and do all this testing process again. I will try to confirm with IPS when they are back from holidays with regards.

    Age Thread

    for a change, it does in China Probably a compatibility/config thing... I use Firefox here
  22. the pressure of 35psi is very normal on a 2.5". you should adjust the pressure to the weight (which is why you have a range) in most cases our weight is more than what could be ridden on the tires so most of the time we need to aim to higher pressures mentioned. p=F/A ... A is increased so p needs to be less. the IPS wheels (LHOTZ to Zero) I remeber they had a huge difference and I was kind of afraid reaching high pressure on the Zero thinking it might blow up which it never did and I think I was on 45+ psi. As being tubeless the walls are more rigid so the tube needs less pressure as it only needs to oppose the force down while a tube one will need more pressure to sustain the walls too (I might be wrong on the last as I am no expert but learning on tire technology). As for the tire and wobble, I can understand that a more round surface might give you a feeling of a narrow wheel to which you need to adopt a bit (you're more like traveling on a rope now). There is also a factor of wearing the tire a bit (I was always suggested not to stress new tires for the first few hundreds of km (probably less on an EUC) on a car until they do their run-in period and get to their optimal state). Also is the rotation of the tire right? Did you see improvement in turning at higher speeds and wider turns as you have to lean sideways a bit on those? I think there it performs better with more road hold and less risky to skids on turns from what I can think about. I was also thinking that maybe the board didn't balance on closing it back. Did you try to hold it steady on flat and see if the wheel pushes more/less forward/ backwards when not loaded? If so maybe a calibration might help. Well done for the job, that new tire really looks nice and even the wheel have a new look now... you're making me want to experiment on my i5 here but that doesn't have the room for changes as you have on your KS. I need to dig deeper for a perfect different road type tire while trying to achieve something new, but will definitely have to wait for now (maybe mid 2018)

    What is the best personal electric transportation?

    Am i wrong that a failure in a skateboard will have it sliding from under your feet? Wheel size depends on the terrain. If it's very well made, a smaller one will go, but I wouldn't suggest anything less than 10" wheel vehicle as you don't know what you might encounter (a tree branch or root, or some flew away waste hoping it's not a banana peel ).

    What is the best personal electric transportation?

    I wouldn't forget about today's electric cars (that can be part of public transport or even trains). I guess an electric car and a small euc can be a brother/sister relationship where you need to travel long distances and fast. for short distance commuting EUC is ideal.They can do each other's role at a cost but together they are most effective. Think about it with cars only since we might be more familiar with it. In the city you need a small one, in highways, a bigger one is better. besides I don't see myself doing a long distance with EUC in some heavy rain. Anything that doesn't have regenerative braking is likely to be least efficient then. Small wheels are not ideal (skateboard ones)

    A new hobby with euc

    well, I am assuming most roads are already mapped in USA. I already uncovered like 20km of new/unlisted roads in China. Hope they will reflect in google eventually as I don't have much access to that from here
