  1. Well I bit the bullet and got myself a brand new Ninebot One E+ from the good folks at Forward California as I couldn't resist the sale pricing they have on right now. As it lucks out when I bought the wheel the Canadian dollar to US exchange really sucked big time so my $600 (inclds shipping) USD purchase wound up to be a whopping $800 Canadian plus $40 bucks for import fees and taxes. I'm not complaining too much as it's a good deal no matter how you spin it. I'm imagining what a $1200 USD KS16 is after the exchange, and whoa I really don't want to spend quite that much... just yet....

  2. Recently I upgraded to an IPS 191 Lhotz 340. And once I have a few more miles on it I plan to make some comments on how I find it. But today I tried it "off-road" on some very poorly maintained riverbank tracks. And I have to say it is fantastic! I don't know if it is the more powerful motor or the wider tire (or the combination of them), but it handled the rough terrain superbly. To the point that I was getting tilt-back within a matter of minutes of starting... I can't believe how well it handles (on and off road)!

  3. If i had figured it was a guy who did it, id be super pissed. But it was a girl so what am I going to do? Sometimes moving object invoke involuntary reactions on the instinct level - like some dogs feel compelled to chase another small animal running by. People are animals and they have these impulses too. Sometimes you just have to kick something flying by you. Lol. Being brought up in a society with an established culture helps us supress these impulses and work out a behavioral code. But alcohol lifts these supressions and allows us to be more in touch with our animal instincts. also i

  5. I don't want to expose innocent pedestrians to any more noise there already is. There's too many teenagers and others that blast shitty music out of their cellphones speakers or crappy BMWs. However if there isn't people around like when riding at night somewhere on silent roads, I might listen to some radio station through my wheels speakers.

  6. I like pushing the limits of my 9bot 1E+ and the fastest I've been able to go (and get a screen shot) has been 26.3 km/hr. I feel quite safe at the higher speeds cuz I'm always aware of what's ahead and always feel like I'm in complete control - I plan to get a GotWay MSuper 3 when they are available - it has an 18" wheel, can go up to 45 km/hr and a distance of more than 60 km/ charge. I'll also be investing in a helmet and gloves!

  8. Just bought it from Taobao two days ago. Might be used like a wheelchair for the elderly who gets tired of walking. It can also be used as a walking stick that always stands upright. Pro: It is easy to learn. It is easy to control with seat, but suggest not to go too fast as acceleration and deceleration takes a while. In order to stop fast, I really have to use my legs to stand up so my center of gravity is quicky shifted backward. This car can be easily dragged along when it is off, so it is quite convenient to take it around. It is only 503mm wide, and is more narrow than the Ni

  9. Some time ago I started a thread on Safety: In most threads the sentence safe/ safer/ safety is often misinterpreted. Reliability - to work as designed, works every time if the system has no malfunction Safety - A malfunction will be detected and the system reacts (behaviour handling) to keep the system in a failsafe state and prevent the unsafe state. In some functions you can see minor (safety) routines in more modern firmwares: Overheat detection results in beeping/ tilt back, overcharging results in beeping/ tilt back.

  11. Don't quote me and I don't want to check its all to do with how the motor is wound, more or less windings. So you can have more speed or more oomph (torque) I want (need) torque because I am fat. EU wheels are quite interesting as they are not that whizzy, they have to produce power at ridiculously low rpm. Bottom line it is not a switch that decides these things. Jer

  12. I updated from 1.15 to 1.20 and did 50 km riding in different conditions afterwards. When I pressed the button "download", it took several seconds for download on the phone (Samsung galaxy 3 and fast internet). Just in case, before that, I removed the SIM card - did not want eventual phone call interruption. Second step was longer one, when the firmware transfers to the KS16. After a minute transfer, I decided to leave the phone on the table.....and the process stopped and I thought "Now I'm f...ed" . Waited a couple of minutes, nothing happens and then pressed "download" again. This

  14. Yeah, those cells are phenomenal! In the ideal world there should be a mfg law requiring all 16 cell Wheels (Airwheel x3/X8 & IPS a130s (mine do ) ) to contain >10-15A cells like the 30Q & HG2.

  16. You could just overlean at slow speed and the motor will give out. I have thought about knowing what it's like to have a shut off too. I might try it on grass, try to speed up faster than the wheel can handle, and hopefully at low speed. But am wondering if overlean cutout might damage the controller.

  17. Congrats on the new wheel! Nice choice. I've heard good things about the IPS 191 Xima Lhotz (Holy cow who thought up that name? It is distinctive though!). The battery cell arrangement is quite unique and makes use of the available space. Happy trails!

It's so easy to go from hero to zero on these EUC's that one moment you're the coolest and people are watching and in the blink of an eye you're doing a not so graceful scamper off while the wheel topples over.

  21. The Rockwheel was probably the most open design anybody made. Everyone else has made very closed designs with the wheel almost entirely covered to the point where you can't even get an air pump into the valve of the tube without an extension. There are a lot of good reasons to keep the wheel as enclosed as possible, for example if anything were to slip in there and jam the wheel it could burn out the MOSFETs almost immediately. If it was your hand or foot it could be even worse for you! A more enclosed wheel also prevents dirt or mud from being thrown up onto you. I have the same proble

  22. We are thinking exactly alike! I have visually checked all wiring and the control board, nothing Is jumping out at me. I'm an instrumentation tech, so I'm no stranger to termination and electronics inspection. Here is another symptom... charging the wheel is not possible unless the power button is turned on, the pack showed full charged while riding, resting pack voltage is 60,5v. I have swapped chargers between the wheels and it's always the same problem. Part of me thinks these problems stem from the BMS portion of the controller? Could a bms fault trigger major tilt back?

  25. I wonder if it's possible to purchase an IPS 121+ control board with BT and connect it to a regular IPS 121 wheel. Are the motors the same in each model? I think @Jason McNeil said the IPS control boards are standardized so does that mean they use the same board in all of their wheels and just program specific limits and characteristics to match the motor? That would make a lot of sense in terms of economy and production efficiency as why re-engineer the control board for each different model if the only thing that changes are maximum speed, tiltback chacteristics, and maybe a few other ite

  26. I think the right way to say it woukd be that @vido on the ninebot can accelerate faster than someone else on kingsong. Ive seen this guy go - he is like a bullet, one with the wheel, knows its limits and accelerates hard, only a smidge short of overleaning. We didnt do a test, but being that he is much lighter than me, he most certainly can accelerate faster on his ninebot than i can on my ks. Pehaps faster / harder response is another reason, like @houseofjob says.

  27. That is how it is in the US. A green light for cars means they can turn right but must yield to pedestrians. If there are pedestrians about to cross the car must stop. Most drivers do this correctly but of course it pays to be aware if you are a pedestrian (or on a EUC).

  28. An unexpected shut down sounds ominous and by the sounds of it there is no way to practice for this unfortunate event! When I flew helicopters we would cut the engine all of the time and practice auto rotations both in a hover and at 1000 feet. It became second nature to go through the controlled maneuvers in the event you had an engine failure. This situation on the other hand relies totally on luck. Kind of hard to file a lawsuit against the Chinese after you are all busted up.

  29. Where do you live? Maybe someone is closer than you think? I normally travel between 19 and 20 Kph each ride (12 MPH). NEVER had a cut out or fall while riding. Only fallen when riding super slow and even then, just tipped over, no damage to me or wheel (legs were tired). Would love another 1-2 miles per hour speed and double or triple distance, but then, I would not be riding one of the most comfortable wheels available. I have 2 batteries and swap them on long rides. Gives me over 30 miles per charge that way. I also believe many of, (Not All of), the falls are human error or ove

  31. I commuted on a nb1e+ for about nine months. I am 110kg, my communte 2.5km. The road very smooth, slightly hilly. The nb1 performed good enough. I commuted through most wheather conditions (rain, wind: 6-7 bft, cold: -5 Celsius). The nb1 was a trustworthy machine for me. 1100 km whithout problems. Pretty soon though, I wanted more: - go quicker (19 km/h becomes pretty slow pretty soon ) - go farther (why only commute?) And yes, I said 19km/h, because you want to prevent going over 20km/h all the time and experience those tilt backs. So I saved money up to get a second whee

  32. I finished my power stage PCB prototype and ordered some to test. It has pin layout so Ti instaspin boards just clip on. When VESC 5 firmware is out I can just make a small module with a STM32F4 and MPU9150 with the same pin layout, or just integrate it directly. It has thermal vias and large copper plates for cooling, I left space under the mosfets so a cpu cooler can be mounted. Things I still need to solve: Isolation of analogue voltage readings somehow. The test PCB doesn't have full isolation. I think you can do it with OP amps and and optical isolators but I'm not certain how t

  44. @SuperSport I think I didn't write very clearly. I believe that 15mph probably represents the top end of my E+. What I meant was that the E+ would allow me to go faster *than I want and need to go*, but usually I start to self-limit at around 12mph. There is that little voice in your head, to which you referred. I have only hit that 15mph once. It is just too darned fast for my tastes.
