I post this in hope it may help another relative noob to tidy up ebike cabling, mine was a dogs dinner for ages and I see a few about too.
Built this ebike approx 1 yr yr ago, it's a kit, a 1500W rear hub with a 17.5A continuous (35A peak) controller and LG 52V 17.5Ah Hailong.
The bag that came with it was marginally big enough to fit in the controller, given some of cables are twice the length they need to be was struggling to fit it all in this bag without the possibility of stressing/damaging some of the connectors (there are a lot!). Was not in mood for cutting and shortening the long cables.
My only previous experience of cable management was building a few PCs over the year, even then I tended to make it up as I as going and the results were good enough.
Was not looking forward to re-cabling the ebike, I've had a bin bag wrapped the loose cabling in front of the bag since I built it apart from one time time tried another bag but it was disaster so reverted back.
Spent a long time looking for possible solutions and eventually plumped on this:
https://www.amazon.co.uk/dp/B07KCP18C8?psc=1&ref=ppx_yo2ov_dt_b_product_details
When it came it's only marginally bigger than the one I have however a little fatter, grrr.
Had to take dremmel cutting disc to the metal lugs on controller that you use for mounting it to a board as they stick out almost 1cm each side, the metal is thick and dremmel blade made it guy fawkes with all the sparks however after gorilla taping rough edges I've got some space back.
There are three cables that come from underneath where the bag will be mounted, power from battery cradle, power to rear hub and pedal assist Hall sensor. So I made a hole in bottom of bag on at the bottom of the horizontal big enough to fit through the three cables/connectors.
The remaining cables come from front, ebrake, display and throttle as well as normal 2 brakes/2 shifter cables. Grouped the kit cables together using cable ties making sure to allow for slack so the front wheel can fully turn each way then jammed everything as carefully as I could in to the bag and zipped it up....and it all fitted...just!
Finally used a few more cable ties to tidy up cabling and that was me done.
So, from this:
(bin bag not yet 'installed')

Bin bag 'installed'

To This:

A lot of stuff to fit in such a small bag!
(You can see my 'mechanic' is more interested in FIFA and toast....)
