Repair Knog PWR Rider headlight?
« on: September 12, 2020, 08:44:24 pm »
HK has a couple of Knog PWR Rider 450L headlights as back up lights because she likes that they can double as power banks for GPSs and suchlike.

She has just managed to break the tiny piece of plastic that connects the strap bracket to the aluminium body. Is there a non-destructive way to disassemble the light so that I fit a proper nut inside? It seems to be commonplace for these particular lights to fail in exactly this manner, so I can't be the first to want to repair one.

It looks like it should slide apart but I don't particularly want to turn this into multiple broken bits. The rear USB section slides out about a millimetre fairly easily then stops. The light still works. The diffuser looks like it should slide out downwards but might be glued in place. It certainly resists a certain amount of force without any apparent movement.

If I can't get this thing apart, I'll just use an external clamp, which will be ugly but functional.

Knog’s UK agent Silverfish can't tell me how this thing was put together (really?) but have offered to replace it, which is a bit wasteful but nice of them. Something to sort out.

Knog are good at replacing broken bits but I agree that some of their designs are woefully under engineered.

Replacement arrived and in service.

Also ordered a cheap torch handlebar bracket so that a similarly failed headlight could continue to be used.
