I’m going to learn from your experience and take an array of photos of my ACM before selling it. With the new shells, side panels and pedals it will be easy to determine if the wheel was abused by the buyer. Link to comment Share on other sites More sharing options...

Did he bring back the ACM and said something like "i am not able to ride it, so please take it back" or did you offer a 2week test time? And then the axle and the trolley were broken?

With the new shells, side panels and pedals it will be easy to determine if the wheel was abused by the buyer. This is always a good idea ...taking photographs of the item right before you box it up. Or before the new owner takes possession. I build and sell road bikes in the side to supplement my income. (High end frames and components...$1-$3k price range usually. And always ...always document every inch of the bike before sending it off . I’ve had a few PayPal disputes in the past and the photo evidence has always helped resolve them in my favor .

I thought you sold it to a "friend".....MIf you have friends like that you dont Need any enemies ;-) Ours is a very small community and I didn't want him to think I was trying to screw him by selling a defective wheel. I heard second hand that he was bad mouthing me because the axle broke. Joey opened it for him and diagnosed the issue as the wire side of the axle had snapped. I don't need that kind of aggravation, and I thought, "just maybe I did damage the axle when I recently rebuilt it". I did ride it about 70-miles after the repair with no issues, so I had my doubts that the problem was mine. He told me he rode it with no issues and then when he was at a stop, it started shaking. But I choose to accept blame and give all of his money back. The $635 seemed a lot more important to him then it was to me. Two days later I'm in my workshop and decide to take a look at. That's when I notice that the trolley handle has a bad twist to it and the left side of the bracket that is screwed into the bottom of the shell is twisted and ripped out of the shell (screw missing). I knew for a fact that the trolley handle was in perfect condition when I gave it to him (I had cleaned the ACM before giving it to him). So clearly he had at least one accident of some sort that was severe enough to bent the trolley handle and rip it out of the shell. And he didn't tell me about it. His omission of this accident tells me everything I need to know, along with the fact apparently he was drunk when bad mouthing me to others. So I classify him as a low character individual. I've learned my lesson, and as you guys suggest, next time I sell a wheel it will be clearly stated that the sale is final. That might make it harder to sell as I emphasize this fact, but it has to be. I can't go through this again. But like I said, I'm going to turn this into some lemonade. Convert it to a ACM2, put a knobby tire on it, and dedicate it to wild mountain riding Link to comment Share on other sites More sharing options...

The sequence for the other connectors is not important. I have no experience with the BMS, but I would imagine that if you can charge and have full capacity, everything is good.

By battery connector on the control board you mean the larger gauge wires with the xt60’s on the PCb side ? So the charge wire and other smaller red and black wires with the black clips first ...then the xt60’s? Link to comment Share on other sites More sharing options...

I just reconnected my ACM packs an hour ago. The 4 BMS cables can be connected at any time. My method: 1) connect the 2 BMS connectors and then the XT 60 connector on the non mainboard side first. Secure your side cover. 2 flip your wheel over and connect the other two BMS connectors and then the other XT 60 battery pack connector. *** Not the connector going to the mainboard**** 3) once all of the other battery and BMS cables are fastened you can now connect the mainboard to the battery packs.**** Be deliberate when you connect these together. Sometimes there is a small spark. Be sure both the male and female xt 60 connectors are position correctly before trying to insert them together or your could end up with a huge arc. Wear leather gloves if you are unsure ir worried. I still wear them when connecti g packs just to be safe. 13 minutes ago, Scott Henley said: New xt60’s...now to connect it all up .... Nice job!!!
