There is no stick shake or warning before it shuts down?....Thats nothing like a real Segway if thats true!

One of the less understood aspects of the original HT and PT Segway models is that almost everything important to staying upright has a level of redundancy. I do not know whether the new "Segway" products have such redundancy, but I do not think so.

Although Segway riders drove into walls, into each other, fell on ice, snow, and wet grass, very few Segs actually failed and dumped their riders. I think I recall one, maybe. Without redundancy, this record will change.

The importance of redundancy may not be obvious to some folks, until they think about it.

Redundancy allows one "half" of the intelligence to monitor the "other half". If the "other half" goes away (i.e., quits working), then the half that's "alive" can institute a stick shake, noisy warning, and reasonably-gentle shutdown.

Without redundancy, if it dies, it dies.

System redundancy has been my concern with the Chinese models since the beginning, and I posed the question several times. Seems we now have some evidence...

Very sorry to see someone get injured like this...

Geez! That does not look good at all ...
I hope not also the cheekbone was injured (it looks so).

Best wishes for a fast recovery from Germany!

Been in touch with Ninebot and they want me to ship the unit to Germany to check the pcbs but can't find someone to ship it the parcel companies say segways are prohibited so will have to get back in touch with Ninebot

Transport problems are often caused by the batteries. Although one could expand the batteries and send the rest normal, but I believe that will bring in the present case nothing. It is also about liability and argument. So if the device can provide proof of an accident, I would never send it to the manufacturer's premises, but I would have it examined by an independent expert. Already, the public interest is very large, so the manufacturer's test result is already established.

I could write here now that the manufacturer will answer something like that: "We have the PCB's checked and can not find any error. Your fall must therefore have been a driver's fault.". But of course I do not write such a thing here.

Nice that the cheekbone remained intact. I wish you continued good recovery.
