@cw_o Welcome :)

If the price is okay I'd take the risk. Getting actual chips from companies like Mouser, Digikey and LCSC can be pricey once you get to the shipping screen. I've gotten chips from eBay and AliExpress (likely the same source) without many issues for things like IMUs, Mosfets and a handful of logic ICs.
Get multiple though just in case you need to redo it. No more than 5 should be fine. IMU's are fragile so you may need to try a few times.

@lia Update: It is indeed NOT fixed. After 2 half charges, the symptoms returned. I have noticed that it happens when going uphill. Going to do some testing on the BMS and see if I can track down any faulty parts.

@cw_o You can try NRF or DigTilt to recalibrate the imu, have the board level when recalibrating.

@lia Tire is good, but I'm only a couple rides in. I've been trying out different ride modes, so not sure what's the tire and what's the mode/settings, LOL. I have not noticed any real edge when carving, so that's good. Size increase might also be a factor in why the bumps feel smaller.
