Torque sensor arm kit Rocky Mountain Powerplay 2018-2021

The ROCKY MOUNTAIN POWERPLAY "Torque sensor arm kit" torque sensor is an essential part of the bike's operation.

Sold without wheel (ref 1998020PR to be ordered separately)

It is thanks to this ingenious system that the level of assistance is rigorously proportional to the force that you apply on the pedals of the Rocky Mountain Powerplay.

When you pedal, the chain tensing comes more or less operate this lever that requires more or less assistance to the engine via a magnet / sensor that is more or less close to each other.

It must also be ensured that these parts are always clean. By removing the right housing you can clean them with a cotton swab from time to time. Same for the magnet located on the rear disc.

This piece is a "calibrated" spring and it requires to be handled with care. Under no circumstances can it be operated by hand, twisted or de-twisted because it will change its "calibrated" voltage.

It is this piece that on the display I-wok the manipulation "calibration of the torque sensor" calibrates. If handling on the I-Wok does not solve your problem, it must certainly changed this room.

If you change this part, it will be necessary to redo the "torque sensor calibration" on your Iwok control.
