Hi all, I have a new (Bulls) ebike, and am hoping to get some recommendations on accessories including:

• Cargo rack bag (what is this called?), I have the rack over my rear tire, but need something that can carry a modest amount of things, thinking a bag of groceries would be nice to fit in there. (I couldn’t pick up a bag of sugar today and having something that can carry things would help)
• Water bottle holder
• Cameras maybe? Reading the other thread thinking about a coupe
• Repair kit/emergency kit

I have a bike shop but they’re more repair/new bikes, and don’t have many accessories so I’ll probably be limited to unfortunately Amazon, but of course prefer smaller sellers. Thanks!
