Ok so I'm yet to take delivery on my bike but I've done a lot of reading up on these and the same thing keeps popping up and that's the section above the motor is a bit of a problem area for collecting crud.

Can you give me some ideas and suggestions to help keep it as clean and tidy as possible.

I'm thinking something as simple as a black sponge or some foam cut to size?

Anyone got a better suggestion?

Cheers

sponge/foam is a pretty bad idea. Being absorbant.
motofoam is what you need. Google it (it's also called sump foam)
Search on here for details of where to put it and how to cover the entrance.

That Moto foam is just fish tank filter. Some sellers on eBay have the same stuff for sale under the difference titles. I'll get some ordered this week

I see what you have done there, but I think crap would still get down that, and though the back - it tends to get stuck where the cables go above the motor.

I dont actually think its a massive issue, as long as you are aware that stuff gets in there and clean it out. The main place collect is between the frame and the motor, where the cables go in, putting some motofoam in that area stops this, but its easy enough to clear out, unless you never do it over a winter and it gets jammed up.

This is behind my motor cover, opened it up the other day for the first time since Autumn as was pleasantly surprised at how little had got in there. My other bike I have moto foamed in this area, but not got round to doing it on the e-sommet. Lots of people have also taped over the edge of the cover with gaffer tape etc to seal it up

Yes i actually agree that it is probably not i Huge problem of you not cover it upp , i have a mate that has the 2019 e-sommet and he has not put motofoam on His bike and His bike have Beeen really Dirty and nothing have happend.

The biggest reason i cover it Up is beacuse am afraid when i wash the bike that to much water Will come in and maybe the cover helps a Little bit.

No. As R120 says, I wouldn't do it like that either.
It looks like you've made a nice wee collecting cup for crap to sit in
The important parts to tape/silicone/motofoam are the connector bay (silicone or tape along the top) and filling the red circled opening in R120s pic)
I have motofoam under the wiring nest too. as it stops anything getting through and between the frame and top of the motor.
I also made a small plastic flap from plasitc food packaging - Spar/CoOp* chicken Pakora tray works well. (They do a mixed pakora version too).

*other shops also sell packaged food in black trays
plastic cut to shape so as to cover the cable nest but not foul the shock. Edges bent upwards to form a scoop. and as you can just about see just the front portion is gaffer taped in place. This means any crap that does get in now has a clean route out the back over the main pivot/chainstay yoke and shit no longer accumulates in the cable nest. the beauty of it being a flap is it can simply be flipped up to have a look in there at any time.

Kinda dusty here just now, eh?

contrary to the belief it's not really an issue, if you leave the Esommet as is, use it for properly manky rides and use a hose to blast the shit out of your cable nest water and mud will definitely end up in the connection bay. Many folk have had E13 errors and shut downs while riding because of this.

with the dropper cable IIRC out the box it is attached via two zip ties to the shock window/seattube. Firstly they are usually done too tight, I would replace them and tighten them but not so the cable outer is totally clamped and has no movement - also IMO the cable/cable outer as fitted from factory is too long, meaning it coils up and cause issues with a smooth action of the dropper, I would cut it down so that it come just above the seat collar so you can still remove post.

Holy smokes, the dropper cable is sorted. Trying to get those cables back whilst relocating the motor is a nightmare, even upside down.

Just a update on this post. I've had a few goes at making something suitable to cover this section using different materials and I think I've got it as good as it can get.

5mm foam cut so size and also cut around the shock mount. This seems to keep any crap from getting in from the rear wheel and doesn't foul the shock. Silicone at the front so that it can be lifted like a flap if needed.

I was thinking about silicone all the way around the edges but I don't think its needed as it's a pretty tight fit.

Hope this helps ?

@Gary and @R120 what do yous think? Is the pic below overkill?
I’ve cut motofoam and filled mud pocket and then taped up from the bottom. The shock moves freely and water can still get out. ??‍♂️
I’ve also motofoamed above the motor.

TBH I just have motofoam between the frame an motor, and nothing on top/above - I would say ride it around for a while and then take it off to see if anything is getting stuck in there.

You don't need to fill the entire shock area. Just stop mud, debris and water getting into the wiring nest. Or in to the motor connector bay. there's a gap to the top of the connector bay (and ester/mud can enter under the wiring nest ).
I have motofoamed the wiring nest and that gap behind the connector bay
And have a homemade plastic spray/mud guard that stops anything firing into the nest.
