I bought an Aventon adventure 3 from the Rochester Hills Eriks bike shop. It was a very good purchase overall Salesman setup delivery and so forth.However when i took my post and my seat in for service , because of a side to side motion i was told that was normal that most aventon bike have this flaw mechanic told me that Aventon was aware of this flaw he called it bad quality he told me he would not look at the problem and even said he would tell his other mechanics not to look at it either. I didn't understand why he wouldn't look at it. that purchase was over 2100 dollars so my rating is for Customer service and mechanic service and not the E-bike . very disappointing. read more
