I ordered a second downtube battery when I purchased my 380+ step- thru in June. I told the shop owner he needed to *get the battery cover* along with the battery. He forgot. The battery ($800) came in ... minus a cover. He quickly ordered a cover ($19), but we have now been waiting over 2 months for that cover to arrive. The shop owner keeps getting promises of "next week" for it to arrive. It hasn't yet.
I can easily get 40 miles on my current battery using Sport mode for the most part, but I'll need my second battery if I want to use the Gazelle for the metric century rides. Otherwise I have to ride my Vado 5.0 which has a 500w downtube battery, plus a second (604w) downtime battery that I carry on the bike's back rack until I need to swap out the batteries. Having two batteries easily give me 80 miles of range on the highest assist.
The Gazelle shop owner is at the point where he said he's simply going to give me a cover off one of the 380+s in inventory if my cover doesn't arrive by early September. I would honestly not want him to do that because it takes one of his sale bikes out of inventory. I plan to suggest (should my new cover still be MIA) that he let me "borrow" a cover for any metric rides so that I can return it right after the ride.
