Remove the left crank arm using a crank arm puller.
Remove the chainwheel from the drive side.
Use a bottom bracket extractor tool to remove the bottom bracket.
Clean the bottom bracket shell thoroughly, applying a layer of lubricant to remove any dirt or debris.

Carefully push the motor into the bottom bracket shell from the drive side.
Secure the motor using the Y-shaped motor mount bracket on the left-hand side of the bike. Tighten the M6 bolts with a 5mm Allen wrench.
