Aventon Pace 500.2 Issues
I need some advice on what to do. I bought my Pace 500.2 in April 2022 from my local bike shop. It worked well for 4 years, but in early May the pedal assist, throttle stopped working on my commute home. It's been in and out of the bike shop for almost 2 months and we can't figure out what's wrong with it. My local bike shop, dropped Aventon last year due to difficulties working with the company so they're asking me to contact Aventon to diagnose the issue since the mechanic charges $150 an hour.
Aventon first said it was a cadence issue. I paid the $20 (including shipping), plus $75 for labor. That didn't work. Then they said it was a controller issue. I paid $100 (including shipping) for the controller. I was sent the wrong controller, so I had to purchase the right controller ($100) and send back in the wrong one and they refunded me $92. The controller didn't solve the issue and the mechanic noticed discoloration on the battery and battery charging issues. Aventon said I needed a new battery and terminal ($517). I just had it installed. The mechanic took it for a few test rides, it worked for him, but once I picked up the bike and biked home the battery light turned off and shortly after the monitor turned off, like the whole bike shut off. I was able to turn the monitor back on while while the battery light was off, which I shouldn't be able to do if the battery light is off. The labor for this was about $300 (for the controller and battery installation). I have a feeling Aventon is going to tell me to replace the wiring, the monitor, and whatever else hasn't been replaced yet to diagnose the issue.
I've spent $1020 on parts and labor and the bike was $1600. I feel like I'm blindly rebuilding a bike that may or may not work. Do I continue to fix it or cut my losses? If I cut my losses, what do I do with a nonfunctioning ebike? At this point, it's just a bike that weights 50lbs.
