I agree, it isn't the rear wheel. That appears to still be straight (relative to the axle). Something has failed with respect to the wheel and the frame. Not sure which ICE variant it is.He said the rear wheel buckled. It doesn't look like it did to me. That looks like main chassis failure rather than the rear wheel and that should worry ICE. It will probably twist back with the use of a large lever such as a barbell but will fail again in some other corner. If the original unbent metal wasn't up to it then straightened metal certainly won't be. If he had two hands on the trike rather than filming he may have caught it and countersteered into the field. It wouldn't have stopped the twisting but may have saved him some skin. He's damned lucky it was a slow corner and no traffic. He should talk to the manufacturer.
A. They should replace it and
B. They need to redesign it or identify the defect.
The rider isn't a whippet but he's no porker either. Any commercial machine should take his weight and such a cornering speed. It's a black mark against ICE for sure. Good find Paul.
Whether or not there was a splt tube clamping bolt that failed that statement isn't true. The corner was taken at moderate speed and the only "error" was in filming which was not the cause of the failure.
The main cause of the fall were simple driving error
The usual clamping arrangement plus a short keyway section in the female and a key on the male might help?Also....
What if you need to separate that joint after years of never doing so. You use penetrating fluid to get it to move but fail to get all the fluid out on reassembly. The torque needed to keep it safe will change. Or what if a previous owner had it apart and coppaslipped it before reassembly to keep it free from seizing. What clamping force is required with that stuff in there? Even if this is all covered in some online manual not everyone will read it. Even if it's covered in a safety sticker on the frame will that sticker still be there years later.
The clamping system is certainly capable of doing the job but it needs a redundancy system to back it up imo.
