Original port cover on new bike was delivered broken, a free replacement was sent to me (great job).
Though it appeared to be a simple installation, the new part tore while I attempted to install. Obviously, it can be installed, but without installation tips (lubricate the rubber pull tab with something?), it was impossible to install without damaging it.
***Revised review: Could not be more pleased with the immediate response from the Aventon team. Once my formerly-negative review was seen by Aventon, I received a phone call and I was allowed to clarify what the issue is. They are sending me a new part with some added tech-tips on how I can resolve the issue with the installation.
'Much obliged' Aventon! Rarely do we see such good customer support.
