In my household, we had two e-bikes, one from Lectirc and one from Electric Bike Company ®️ . We bought these bikes the same time and now the battery died for the bike of the Electric Bike Company ®️. We were INFORMED by them that based on our warranty, our battery should be covered as long as the problem is not caused by the customers. We (paid to) mail this battery to them. Today, they told us they detected bad cells in the battery and they would give us a new one. However, we NEED TO PAY the $90 diagnostic fee and $20 for them to ship the battery to us. I am ok with the $20 shipping fee but the $90 diagnostic fee is totally bullsh*t. If it is within the warranty and obviously based on their judgement the warranty covered our battery problems (bad cells), why should we spend $90 diagnostic fee. Honestly speaking, for pricy bikes like theirs, shouldn't the warranty cover all fees (including shipping fee back and forth) if problems are covered by warranty?? $90 may not be a lot of money (compared to the price of their battery and bikes), but I felt scammed by their "warranty policy".
