All good suggestions and I have previously fed back some ideas to Specialized as well.
With regard to the motor seals I suspect Spesh have little leverage given that it only has agreement to govern the motor with its own software....otherwise it is a direct 3rd party supply. The degree to which Brose would be prepared to modify its existing design probably depends on the % of total production taken by Spesh. I suppose another option for Spesh is to arrange modification of the motors between delivery from Brose and installation in a bike. If that added cost so be it.
With regard to the green seals on the motor plug all of the electrical connectors are supposed to be installed with lithium grease. For those green seals and the "o" ring seal on the battery end plug I treat them with silicone lube. Seals like that only work longer terms if kept flexible.
My suggestion to Spesh was that an additional sealed cover could be made to encase all of the connections on the motor.
As far as the TCU is concerned there is no reason why water needs to get into the top tube. The point at which the top tube connects to the headset is open....it should be sealed with a rubber bung. There is no effective seal between the TCU and the top tube. I have made a gasket to fit on the bottom of the TCU. No reason why that could not be standard. Another potential point of water ingress is the stress member of the frame that sits beside the shock. The TCU cables run through there. If the lower point at which the cables pass through is not sealed water will run down those cables to the connections at the motor. I seal that gap with grease but there should be a seal there.
Lastly I can see no reason why the motor covers themselves could not be made both waterproof and dustproof and any gap used as ventilation covered in a gortex membrane.
