I am trying to find out pedal spindle size for the NordicTrack GX 4.7 R exercise bike. Is it 1/2 or 9/16?

I want to replace the pedals with larger more substantial ones with a strap.

Thank you!

    I proposed an edit for clarity: basically, put the question in the title. As it is, I thought you were asking about some random elliptical machine and was going to redirect your question.

The Nordic Track GX 4.7 comes with a three piece crank so it has 9/16 pedals.

9/16" is most likely but not 100% certain.
