Introduction

The torque sensor on some Biktrix eBikes is integrated into the bottom bracket of the bike. If this part fails replacement may be necessary to regain your pedal assist capabilities.


Tools required:

  • 8mm Allen Key

  • 15mm Flat Wrench

  • Crank Arm Puller

  • Bottom Bracket Removal Tool

    • For some Swift models you may need 2 of these

  • Ratchet/Breaker bar/adjustable wrench for use with Bottom Bracket Removal Tool

  • Large Adjustable Wrench

    • Having two of these can make the job easier!

  • Wire Hook

  • Wire Snips/Cutters for zip-ties

  • Replacement Zip Ties

  • Bike Parts Grease (Biktrix recommends Park Tool Polylube 1000 - #PPL-1)

Step 1

  • Remove the chain from the chainring. To do this shift the bike to the largest gear. Push the derailleur forward. Then remove the chain from the chainring of the bike taking advantage of that slack.
