I believe the link on Amazon you have posted is for the 2018 freewheel, correct? I do remember that my 2019 model has an 11-34 freewheel, and it was touted as "new for 2019".
So, the rear taillight was powered by AA batteries or something?
Did the 2018 use the same Shimano derailleur line? The Acera, I believe? Or did it use the Altus or the Tourney line?
