kenmalecki Posted June 10, 2017 Share Posted June 10, 2017 Hi all. I'm a long time 9B1 rider. I bought three of them early last year, right in the middle of the firmware debacle. I was finally able to get all three onto V 1.3.5, and that has been working OK. I searched for a recent discussion on this topic and couldn't find one. i see that 1.4.0 is the latest "production" release, although like most, I have little confidence in Ninebot anymore. Is V 1.4.0 the latest? Can anyone share their experiences with V 1.4.0? If it seems to be stable, I'd like to get "current". Thanks! Ken Link to comment Share on other sites More sharing options...
Christoph Zens Posted June 11, 2017 Share Posted June 11, 2017 I upgraded to 1.4.0 at the time it was released (long ago) and did not have any issues. I did more than 2000km on the NB1 E+. I am riding the wheel at max speed most of the time, which turns out to be 23kph for my model and the 1.4.0 firmware. Sometimes I ride slightly into tilt back, with the wheel beeping at me. I also go up and down a pretty steep road on a daily basis, where the wheel is at its limits for a few minutes (close to the 1500W max. going up hill and around 10-12 Amps reverse current when going downhill). I found this firmware 100% stable and trustworthy. No issues at all. My weight is around 80kg. Link to comment Share on other sites More sharing options...
MOS GERMANY Posted June 11, 2017 Share Posted June 11, 2017 I also have the ninebot one E + and the firmware 1.4.0. What is the reason why the battery suddenly turns off? This is, of course, a major safety risk, and you can make a fall and get more or less difficult. I only know that about 10-15 % battery warning signals come and the pedals raise. Then you should descend from the device and recharge the battery. If you ignore this several times, the battery suddenly turns off suddenly, without further warning signals.

Ken 1.4.0 is almost a year old (or more than) and I don't reacall any problems being connected to this version (other than maybe 8kHz sound but that got introduced in 1.3.5?). Anyway, there is a relatively easy way to go back and forth between firmware versions on E+ so you can try any version you want and revert to a previous versions if you are not pleased with the latest one: Link to comment Share on other sites More sharing options...
RooEUC Posted June 11, 2017 Share Posted June 11, 2017 I have done over 1000km on my E+ running 1.4. I have not had any problems. I have run my battery down so low that the max speed is a brisk walk. It has never cut out. When you say that most people have little faith in Ninebot what are you basing this on? I thought Ninebot machines were generally considered to be quite reliable, well built and safe, albeit somewhat slow and boring by current standards.

Christoph Zens Posted June 11, 2017 Share Posted June 11, 2017 Maybe the OP heard about the problems Ninebot had with their P model, which was ultimately cancelled after problems with the boards and a many failed attempts to fix in software what really was a mainboard not designed to drive the new 800W motor. I think that's what triggered those many firmware versions we saw during that time. I could be wrong though. What I can say for myself is that I never had any problems (not with 1.4.0 and not with any other firmware I used during the last 2 years) and I don't know of any problem reports regarding 1.4.0 running on an E+. There may be some related to the P model, but that has nothing to do with the OPs question. Link to comment Share on other sites More sharing options...
RooEUC Posted June 11, 2017 Share Posted June 11, 2017 Yes the P was quite a failure. The E+ and S1/S2 seems to be as good as it gets for reliability. Link to comment Share on other sites More sharing options...

I think he refers to faulty firmwares that Ninebot rolled out to unsupecting users, especially v1.2.6 caused the EUC to stop balancing, out of the blue... There were some others too but I don't remember the exact version numbers. People became very sceptical to ninebot firmwares after those incidents. Edit: 1.2.9 was a disaster, as well as 1.1.6...

kenmalecki Posted June 12, 2017 Author Share Posted June 12, 2017 Thank you all for the replies and great info! This forum is great - so many willing to help. Yes - I was referring to the firmware releases that made people afraid to upgrade - at least I was. It was clear that Ninebot was scrambling to repair a firmware problem, that they didn't understand how to do it, and they didn't understand software config mgmt. And back then, you couldn't go back after an upgrade. Glad to hear that's possible now. i should probably leave well enough alone, and stay on 1.3.5. But since I have three 9B1's, maybe I'll upgrade one to 1.4.0 and see if there's any noticeable improvement. I do have a vague tilt back happening occasionally at slow speeds. If so, I'll upgrade the others. Thanks all! Ken Link to comment Share on other sites More sharing options...
MichaelHensen Posted June 12, 2017 Share Posted June 12, 2017 I did notice the vague tiltback too on slow speeds.. I am on 1.3.5 and not willing to change :-) I noticed it last weekend when driving next to my wife who was on a bike.. Rather slow driving and I felt the pedals kicking back a bit. I wasn't sure what it meant as I was on slow speed.. but now you confirmed my feel, so I am not worried :-) Thans!! Link to comment Share on other sites More sharing options...
kenmalecki Posted June 13, 2017 Author Share Posted June 13, 2017 I don't like the tilt back. It can be disconcerting and might even be dangerous if I were to overreact, which I think would be the natural response if my brain didn't intervene in time. What's really odd is that I have three 9B1's, and only one has the vague tilt back at slow speeds. It's the newest of the three. Perhaps there are differences in the hardware.

You are in the perfect position to evaluate the differences. Link to comment Share on other sites More sharing options...

I wonder if that was to kill unauthorized resellers profits? By destroying black market Ninebots? I never had a problem with 1.2.5, 1.3.5, and now 1.4.0, but maybe it's because I don't try to overload the wheel. Link to comment Share on other sites More sharing options...

Why would you do that? I mean ride to 14%. My E+ performance drops off in a steeper and steeper curve the lower the battery gets. I just noticed again today that my E+ feels way weaker at 50% trying to climb hilly sidewalks. It's not as much fun to ride feeling like there is very little power left. I am starting to understand why some people like the wheels with larger battery capacity. Even though I don't do long rides, after the battery gets low it just feels weaker. Good to hear the S1 is so reliable. If it hasn't failed in a 100 miles, it will probably never fail. Link to comment Share on other sites More sharing options...

That's the maximum rating, the "power" wheels have that as nominal, and peaks at 3-4kW (3000-4000W) or more... Link to comment Share on other sites More sharing options...

Why would I do that? Simple.. wasn't paying attention, and found myself a mile from home and at 20 percent. It was that or carry it home for a mile. ?

I think I would still buy now at that price if I didn't own one already. Still a good wheel and a good motor delivering enough power for what it was designed for and even more (like the speed of P model by easy FW mod).

Bert08 Posted July 6, 2017 Share Posted July 6, 2017 Is it true that Ninebot stopped the support on One E+ and 1.4 will be the last firmware? I had no problem with 1.4 so far, but I didn't ride much km's... Link to comment Share on other sites More sharing options...
