LOL, absolute confidence. It feels I have read this many times before, only with different dates attached.

Tell me, are you aware of any generic problems with Gotway wheels since early summer? I'm not.

There was a small window where the MSuper's had the bad firmware. Certainly any Gotway wheel made after July 2017 can be ridden with absolute confidence that the firmware is good. It's essentially November. I think you're safe buying an MSuper.

Hi. My dealer says that my gotway msuper is produced at the end of July 2017.

Am I safe or not

In my opinion you are. From everything we know, wheels produced after June 2017 had the good firmware.

[meepmeepmayer]

Yep that should be far after the firmware issue. No worries.

Thanks a lot

I don't keep track of "generic problems" with Gotway wheels. Even if I would, I were probably far from absolutely confidence that there couldn't be any problem just because I am not aware of any (yet). That is in particular so if problems were (notoriously) known until after a last software update.

So basically, regardless of actual reality you will be the Gotway cynic for the foreseeable future.

Yup. That is the problem for MFGs like GW. Reputation is something you can kill pretty damn fast, and it takes forever to build up. If the Tesla and the MTen3 runs without too many problems for a year or so, and no other problems crop up, then maybe people will start thinking GW has finally learnt to do QC.

To do a Yoda:

For GW and RW and others to realise this I wish.
Being in a hurry always they are.
And nothing done properly they get, until too late it is.

Using this terminology, I count the past as "actual reality". The past is quite important to predict the future. In fact, as it turns out, the past is the only actual reality we have to predict the future. To all I know of this world, judging the expertise of engineers from their past work (say, the percentage of flawless updates we have seen over a relevant period of time) has quite high predictive power. Of course, these predictions (AKA prior) are to be adjusted with actual data coming in, which of course goes both ways (to the better as well as to the worse).

This has nothing to do with cynicism, though I freely admit to be outrageously cynic at times... for example if someone claims to have, just this time, removed the last bug from their software...

Unless there's no meaningful competition. I've said it before, if KingSong made a suite of wheels that competed with Gotway at every level (power, batteries, etc.) than I most likely would not buy another Gotway. They don't, so I continue to buy Gotway

My seller told me this:

De GW Msuper V3 1600Wh is after series 0517, so it is the safe version.

Oh boy ... this is going to end up costing me money again ...

The oscillation problem occurred to me a few days ago at about 39kph. Luckily I was wearing a pretty think hoodie and pants so all I got was a small(ish) road rash on my arm and a small scratches on my leg and hip (so basically, no big deal). Anyway, I ordered my wheel (Gotway ACMs 1,300Wh) around the end of August from ewheels so I don't know if this problem had to do with my wheel being from a pre-June 2017 batch or if this was a new problem. Just felt that I should put out a warning since this happened pretty unexpectedly after 7+ months of use.

Coming from EWheels, I highly doubt that your wheel has the firmware issue since Jason re-flashed the wheels in that time period.

Sent you a return label to have the Wheel evaluated/repaired an hour ago. Since you have nearly 1000 miles on the machine, it's doubtful this is a firmware fault, as it would have been exhibited many, many miles earlier. There's been a few incidents of Wheel nuts coming loose on the ACMs, this will be the first point of investigation. 

[atmadams]

Well it happened to me...  I was cruising on my Gotway MSuperV3S+ (bought from eWheels Dec '17) and it cut out while going over a crack in the asphalt.  I was going ~20 MPH when it happened and I fell off and hit the pavement.  There were no warning indications, just a straight cutoff.  Battery was around 70% at the time.  I had gone over this crack hundreds of times before this incident without issue.  I fractured my distal radius and scaphoid all on my left arm.... 12 screws and a plate. 

My experience: ~300 miles on a V5F+ and I had about 400 miles on my mSuper at the time of the crash.  This happened on Apr 15, but I haven't wanted to talk/think about it. 

Yes, I was wearing a helmet (which didn't touch the ground), but no wrist guards.  The wheel rebooted and seems to work with no issues... the wife has decreed that my EUC hobby is officially over (we'll see).

Not sure if this is a one off, or if more Gotway gremlins are to be found.

[Hunka Hunka Burning Love]

Sorry to hear about your accident.    Any previous history of crashes on the wheel that may have loosened up a connector?  Riding in rain?  What is your weight?  Got any Wheellog telemetry?

[mezzanine]

Sorry to hear about your accident, @atmadams.  I really appreciate you posting about your accident even though I know it can be difficult.  It's one of those things that is so important to share so that others can (hopefully) learn from your misfortune and the community can collectively try to diagnose what happened so it doesn't happen to anyone else. 

It's not clear to me what caused your cut-out.  You believe it happened as a result of the minor impact shock of going over a crack?  I've experienced what I'd describe as a "bucking bronco" kind of oscillation on my V8 as a result of hitting a bump at speed.  I was extremely lucky that I stayed on the wheel.  I've always tried to maintain my tire pressure on the low end of what's recommended as a result.  I think it's a design flaw of the V8 from my research and not something unique to my wheel, but one can never be sure.  

I wish I could say that a wrist guard would have prevented or reduced your injury, but I'm not sure it would have.  

 

I've been frustrated with the culture of this forum when it comes to preventing stuff like this.  I get crapped on anytime I try to confront it.

Ugh! Sorry about your accident. I feel your pain! We can only hope that GW and other manufacturers keep improving their wheels so the words ‘cutout’ and ‘faceplant’ become antiquated and imaginary. 

We should start a implant club. We are both plated. You have 12 screws and I have 10 (mine are longer ?.) Does a cadaver bone count for anything?

@Rehab1 I've spent a lot of time wondering whether your injury would have been different or less severe had you been wearing a different kind of wrist-guards.  I have a pair of Triple 8 Hired Hands and a pair of flexmeters and they're designed so differently, while both seeming to offer protection, that I'm at a loss to guess which is actually safer/better.

You should swap them out wearing one of each at the same time... You will still be a Guinea Pig, but in the unfortunate event of an accident we will at least get some valuable data!   ?

Interestingly my hands never touched the ground. It was left elbow and head that hit.  Instead of fracturing my elbow upon impact the baton was passed and the forces were translated up to my humeral head. Not sure if elbow pads would have absorbed some of the forces. Unfortunately I was not wearing them at the time.
