Hi all I decided today to give my trance a little extra clean after normal stuff chain,frame,drivetrain and wheels I've always noticed alot of crud builds up under the motor cover so today I stripped it and underneath was minging thick solid mud and under there is a load of cables for speed sensor brakes and others with connectors there's very little weather protection it's terrible I cleaned it and found the cables were rubbing on the motor housing wearing grooves in the case this is a terrible design I'm shocked really shocked anybody else found this I'm thinking of silicone sealant to seal it ?
Terrible weather protection on motor ?

Yeah, they seem to have gone with "fully sealed, IP67" connectors and thought that would take care of it. As someone who designs electronics for the agricultural industry, I can tell you that in real-world wet conditions those connectors will not prevent water ingress issues occurring. I'm already thinking of what steps I can take to improve it ready for the winter, applying silicone grease around all those connectors will be my starting point. I have some other ideas, but would prefer to keep my warranty intact.

A word of warning if you're going to try and attempt to seal up the whole compartment. Don't forget that seals work both ways. Anything you do to try and keep water out, could end up doing a very good job of keeping the water in! Sitting the connectors/motor in it's own little puddle probably won't have desired result.
It was designed in dry dusty California, so it’s of little wonder it won’t work in the rest of the world

Would wrapping the connectors in heatshrink tubing help?

It could for sure. It just depends on how much serviceability you want to maintain. The best heatshrink for sealing things up is the adhesive-lined stuff, but a that point you're gluing everything together at the same time. Non-adhesive and then seal up where the wires enter with sealant could be a sensible compromise.
I've greased the connectors with dielectric, taped them with electrical tape, and have had no trouble so far. I've done a lot of mud riding. Also use a sock.
At least the connectors are serviceable with only removing a plastic cover. Many bikes require removal of the motor to get access, and yes, even those get wet. I'm not defending Giant here, pick your poison I guess.
If mine quits tomorrow, I'll never buy another one! Lol.

God Im so happy I dont live in Uk, you have terrible weather up there.
As soon as I get some extra cash, I'd like one of these for keeping out much of the water and mud. The socks, work well but are heavy and hard to take on/off.
A little story on the battery/cover of the Giant Trance E2 Pro.
My friend has the same bike as mine but putting about 20kg more on the scale he opted for a new 620 Wh battery. The new battery came (surprise) as battery only, no cover included, so not possible to quickly switch.
That cover would take about 6 months to be delivered according to Giant.
So we switched the 500 for the 620 battery and when removing the battery from the cover we were VERY surprised to see that the space under it was completely filled with dirt...like it was tampered. It was enough dirt to almost fill a teacup.
Since we had the bike we have only ridden in dry weather (we had no rain for months).
I wish I had taken some pictures...
It probably does no harm but as it seems the rubber seals (that were still in place) can't keep dust out.
I can now imagine how the motor compartment may look like...we will check that too.
Anyway, that Rock Guardz posted above seems very useful. Thanks for posting this @MrTeno2U

It's all about your state of mind. Riding in mud is awesome once your awesome at it. Until then it just sucks! At least this is what I keep telling myself.

To be honest, I think the rock-gaurdz will be a better solution. The sock is painful to get on and off, and lasted only one season. Its also very heavy.
I'm gonna try the carbon fiber gaurd this winter.

Not sure what you're trying to take off. You can just remove the 4 chainring bolts to access the blocked allen bolt to remove the plastic coverJust to make sure that I am not missing something. To get the motor cover off I have to remove the cranks and the lock nut? I still hope that I just miss a trick to get the cover off without removing all these parts

This is exactly what I am talking bout and never thought of that...doh
Thanks!

The area may also be there to serve as air vents and keep the motor cool too, so be careful what you do.A word of warning if you're going to try and attempt to seal up the whole compartment.

Hi I've fitted a 34t chainring which means I can take the cover off without moving anything ? tbh the weather protection I can live a sort I think but the cables have worn a groove in the frame that's my worry so I've fitted rubber mastic tape on the frame I've also put tape over the cables inside the downturn to stop rattles then fitted foam strip in downturn so the battery seals properly also rubber tape on both chainstays as my left foot catches it I'm realising we seem to be r and d for the companies and the ebikes are still in there infantsie ?

Was that all one sentence?
I ordered one of these and it seems the model changed a bit. It has a bit of extra material on both sides and really clings around the battery tube. A velcro strap is included but not even needed given the exact fit.
It'll surely prevent mud entering the gap between battery and motor cover and protects the latter. Worth every cent.

Any chance of a photo mate? Sounds really good, but £70 is a lot of beer tokens
Is that a separate mud guard protecting the suspension linkages?
Yes, many of us started stuffing a front mud fender inside our mudhuggers to protect the linkage. I post a link if I can find the thread.
That would be helpful thanks, now the weathers turning i want to protect those pivots and linkages as they look expensive.
