I am really hooked on getting this C21 gravel bike, but I live in an apartment and can't easily charge it every day. Daily commute is around 20 km city traffic in total, and I am wondering if it means I need to charge every night?

And since I can't charge anywhere, does the extender battery help with that? Can I use that, clip it off to bring it in, and never charge the internal battery? Do I even need the internal battery at that point? Could I perhaps just take it out and only hook up external battery?
