Common eBike problems and solutions

Hey everyone!

I'm relatively new to the cargo eBike scene, rocking a Tern GSD, and absolutely loving the utility for grocery runs and kid transport. I was wondering what common problems other cargo eBike owners have encountered, especially with the added weight and frequent stops? For me, brake pad wear seems to be a constant battle, and I'm always looking for tips beyond just "buy better pads."

What are your most frequent headaches, and more importantly, what clever solutions have you found? Cheers!
