I have had 4 Aventon Pace 500 ebikes over the past two years. ALL 4 Displays reset after X miles. This is well known problem for Pace 500 Displays. I received replacement Displays on 3 of the ebikes. 4th Display received monetary rebate from Aventon. Reset Display works fine. Just know that Odometer may reset again. I keep actual mileage on database. So no problem. The 3 Replaced Displays have wierd 'feature' of displaying both KM/Mi icons on Trip B. However, only miles are actually displayed in Trip B. All other Display functions work normally.
