Thanks for that, I'll investigate that routing today.
You guessed right on the dropper post. We ordered 4 bikes on the same order, 2 CC and 1 EX for friends, and one for myself, and I just put a dropper on each one of them as a default option. It is mainly my 5'2" spouse that will ride it, and it is a good fit for her with the seat post all the way to the bottom and the dropper post about 1/3 extended. But the ability to accommodate my 6' frame from time to time, which will require the ability to raise the post as well as the dropper, would be a desirable feature.
BTW, another desirable feature of a dropper, even if the rider does not require it, is placing two opposing bikes on a trailer hitch rack. The ability to adjust the seat height allows you to nest the two bikes optimally side by side.
Edit/Update: Got the problem sorted. It does not route via the motor, it goes internally through the crossbar. It seems to work its way back toward the front, and then as it has to make a 90 degree bed, it binds up. The solution is to try feeding it from the entry port on the frame while pulling the seat post up and down and eventually the cable will feed itself back toward the seatpost and the seatpost will come up.
