Good for you. I've only had to change one wheel bearing in my life, and I took the knuckle off the car and brought it to my mechanic.
Are you retired?
Also: mods you should be planning:
1) Engine kill switch. You're going to discover that the default programming doesn't stop the engine nearly as soon/often as you will want it to. EG. it won't stop the engine above a certain (low-ish) speed... much loss of potential fuel savings right there.
There are numerous approaches for accomplishing this. I chose the easiest/simplest.
2) "Clutch switch": enables you to decide if/when you want assist. Very useful in preserving SOC in a weak-ish battery pack.
I mostly drove mine without using assist, but regularly flipped the switch to access regen.
(PS: you should really have a dedicated thread for this! It's a vehicle, not a random small thing! If you agree, I don't mind moving the existing posts over. Just tell me what title you want on the thread.)
