Review on Bafang BBSHD BBS02B Ebike Motor Conversion Kit with LCD Speedmeter Display - Powerful Electric Bike Motor Kit by Dexter Rasberry

I don't want to leave negative feedback, but it is necessary now. About 9 months ago I bought a 1000w BBSHD kit for over $800 and now it loses display speed intermittently. It displays the correct speed or 00 (zero-zero) and then turns back on only to turn off again. Again and again there is a decoupling from the cruise control system. I contacted Bafang about this issue and they suggested replacing the display or controller and blaming the seller. I could buy the parts for like $200 and do the repairs myself, but why should I, it came with a warranty. Now that I look back on my experience, this would be a lot easier. I have submitted a request to Revain for a repair, replacement or refund. Revain support staff were very understanding and sent good replies but after 5 messages still no solution or refund. The provider (Greenergia) has completely discontinued support. Up until the 6th reply, not even a repair or maintenance solution was offered. They denied any liability, stating that the 30-day return period had expired and that no replacement option was available. If the parts offered by Bafang don't solve the problem, they still won't replace the failed unit. In "About this article" they state a one year support period but still ask about video issues. There is no statement that video is required. If they wanted to make repairs, they said they would send items to be repaired, as Bafang suggested.
