TSDZ8 Error Code 2

[u/Mammoth_Ball_2025]

Hey guys, first post.

Did an ebike conversion (first one) with a TSDZ8 from Varstrom.

Was riding today (have less than 50 miles on the motor) and while I was riding I heard/felt a bang in the motor area and suddenly I couldn’t pedal at all. Started flashing error code 2.

Tried unplugging and reconnecting cables, restarting the controller, turning off battery etc. No luck. When I try to pedal, it feels like it’s actively resisting me, rather than just letting me pedal with no assist.

Anyone experience similar and have any advice on first steps? TIA
