These models are also equipped with a convenient folding design, and provide an incline offering that ranges from 0 to 15%, and speeds from 0 to 12 mph. Neither have interactive training, but both provide cooling fans built into the consoles.

The F80 is equipped with a slightly less powerful motor, a 3.5 continuous HP motor, in comparison to the 4.0 continuous HP motor of the F85.

While both models offer a lifetime of coverage on the frame, motor and drive systems, only the F80 offers 5 years coverage on electronics (the F85 offers just 3 years on electronics).
