This is part of the force you exert when you pedal your bicycle.
How can we apply this data as an external force to the model?

Hi,

First, convert the force data into OpenSim format (STO or MOT files):

Then, assign forces to bodies:

Thank you for reply.

Is this possible with a single axis force sensor?

Kind regards.

Hi,

I'm not sure, you can make zeros for other axes.
