QS138 motor mount
STL & CAD files

Prototype and fabrication resources for QS138 conversions, organized by the exact motor variant and donor chassis instead of treating every QS138 as interchangeable.

Variants will stay separate

  • QS138 V3 70H geared motor
  • QS138 90H motor
  • Motor-envelope model
  • Lower cradle or plate geometry
  • Donor-bike-specific conversion mount

Every EMR listing will identify

  • Compatible motor label and measured revision
  • Donor chassis and model years tested
  • STL, STEP, DXF or editable-source formats
  • Prototype versus final-fabrication purpose
  • Material, fastener and clearance notes

Fitment warning

QS138 V3 70H and QS138 90H are not the same package. A generic search result is not proof that the shaft position, gear case, mounting faces or bolt pattern match. EMR files will state what was physically measured and what still needs customer verification.
