What we measure

Bench test scheduled

We haven't measured this one yet. When our unit is set up, it gets the same checks as every machine, and the results go here:

  • Noise from 3 ft at 3, 6, 9 and 12 mph
  • Incline at the top setting, with a digital level
  • Watts at the wall, idle, walking and running
  • Assembly time for one person
  • Folded size, measured with a tape
