Pedal Assist (PAS) or torque sensor? If you enjoy pedaling and/or saving battery then you may be interested in some assistance. In certain locations pedal assistance is also the law. The two most common types are PAS and a bottom bracket torque sensor.

Pedal Assist System (PAS)

pros:

  • Inexpensive
  • Generally included with hub motor kits

cons:

  • Limited by the controllers algorithm, whether that be good or bad is left up to your controllers software
  • Measures crank movement instead of force, therefore not as accurate or efficient

Torque sensors (bottom bracket type)

pros:

  • More accuracy and efficiency
  • Measures the force you apply to it and can distribute proportional force (or more, depending on your software)
  • More flexibility, feels more like a bike than a typical PAS system.

cons:

  • More expensive
  • Requires drilling a hole in the bottom bracket shell for the wire
