Hub Motor Umbilicus Quick Connect

The electrical umbilicus from my 2000 watt brushless hub motor goes directly into the main wiring bundle before it gets to the controller which makes it a very big hassle to actually separate the rear wheel from the bike. Changing tires, or fixing a flat (tubeless tires) becomes a costly, time consuming chore even if I can get the bike to the motorcycle repair shop. Can someone tell me why you can't install an in-line connection somewhere on the umbilicus or how this can be done? The umbilicus is tied to the frame at three points with zip ties so it seems that a connector could be placed between ties to limit stress on the connection and prevent pulling the contacts apart. Any suggestions appreciated. Thanks!

Piece of cake. Things to consider. Waterproofing. Heavy gauge connectors. Easy to do, just take these items into consideration. When you cut the wire, space the connectors. You don't want them all bunch together. Use multiple layers of water proofing. Good luck, Poe

Don't buy any futher away than you can drive to and return it.

Thought so, seems simple and logical. Wonder why manufacturer didn't address this?

Thanks!

Re: Hub Motor Umbilicus Quick Connect

mainly cost, but also there is the implication by putting a connector there that the bike would eventually need servicing. ("what? these things virtually ride forever without a care".... um, yeah, heard that before) Seriously, though, the bulk of a connector set might be what they were wanting to avoid, more than the practicality of it. Yes, to service the bike's rear wheel, it makes perfect sense. Electrically, it can be a weak point which would allow heat buildup and potentially failure of the circuit at the connector. Even a huge conncetor on the non-rotating motor cover would be easier than working on a rear wheel with a tethered wire loom though.
