The QS138 has had both bearings replaced because of a faulty factory bearing. Shows some scuffs and marks from me opening it up, but works well. Comes with the HTD pulley and the 428 chain sprocket.

The BAC4000 is running 5.x.x firmware, which I don't think ASI officially supports anymore, but I have the windows version of BACDoor for the controller and a mobile login that should work.

QS138: $300 + shipping
[SOLD] BAC4000: $450 + shipping

Questions are welcome

Is the BAC tuned for this motor?

Were they ever run together?

Can't tell from the pic. Is this the tapered shaft or straight shaft motor?

Are you in need of any ebike stuff such that you would be interested in partial trades?
 
I have the file for the qs183, but the BAC is pending right now. Tuning the BAC for any motor is just a matter of hitting a few buttons, the controller does most of the work, similar to VESC.

The motor has the tapered shaft with woodruff key.

I'm not really looking for any ebike stuff right now, just want to sell.
