Better then I expected

I received the two packages about 2 days away from each other which was fine as I was not ready to upgrade my fat tire bike. I thought I was not sent all the parts but the display was in fact not missing. The ECU case was also not missing I think they just moved to using zip ties. After figuring these two things out everything installed fine and rode well. I think 25mph is what it ends up at or so. I have no complaints but of course now I want to make it faster LOL
