I would get a tire insert for the rear tire like a Cushcore or Vittoria Airliner. It protects the rear wheel from dings but also reduces the air volume a bit so the bike won’t bounce around too much on the rowdy stuff. It makes my 2.8” tire feel more like a 2.5” tire but you retain all the traction. My BB measured 338mm with a 170mm fork up front. It’s pretty damn low so mabe some crank boots or possibly shorter 155mm Miranda cranks (33-36 Euros) is a good idea depending on your trails.
Paint protection is a must. I just used cheap 2” and 4” wide helicopter tape and cut it to size. Cheap and took under an hour. If it gets scratched or starts peeling, it takes a couple minutes to peel and reapply.
Last thing is to check your suspension and get it dialed. My Decoy Base came with a Yari fork and 4 volume spacers installed which is way too much. It works better with 1 or zero IMO.
The shimano app is finicky. The motor is set by default to eco Low, trail Low, Boost High. I Changed mine to eco high, trail medium, and boost high. You will suffer in Eco Low, its worse than an acoustic bike
