Issues with my bike

[Nomad1]

Yep, the shop that built the bike had the cable housing kinked up pretty bad inside the seat tube each time they slide it in. In fact the outer (black) portion of the cable housing was completely skinned off in sections, I dont think they were aware that the battery needs to be removed when sliding the cable housing in or out on that bike.
Pulled the battery and the motor to learn what was scrapping the housing up so bad. The cable routing over the motor on that bike has a few very sharp edges that are prone to hang up and scrap the cable housing. Also very congested with wire harnesses. The mechanic that figured it out arranged the harnesses to improve the routing and added a outer sheath to the housing where it passes over the motor to protect it and help it slide a little better.
The main thing will be to ensure that anyone that pulls the dropper post removes the battery first and feeds the cable housing from the battery compartment.

glad to hear you were able to get to the bottom of the problem.

Like I said earlier - I think this is likely to be the issue!
