RPM, Speed and Power — BikeErg vs AirDyne6 vs Assault Bike vs Echo

Hover over or tap the graphs to see the values for each metric. Click or tap the legend markers to hide or show each series.

Below is a description of how the data for these charts was assembled. Reading this is not necessary.

Method

Data for the Concept2 BikeErg was collected in the same manner as described in this article. The Schwinn AirDyne6, Assault bike and Rogue Echo data were collected by video recording the respective manufacturers' monitors at increasing RPM.

Setup

• The BikeErg used in testing was brand new.
• The Schwinn AirDyne6 was quite a few years old. However, it has had regular maintenance, including belts being replaced prior to testing.
• The Assault bike was less than 6 months old.
• The Rogue Echo was a couple of years old.
• Flywheel cages had dust and debris brushed out.

Collation

Data was collated in the same manner as described previously.

Caveats

The graphs presented above are based on results recorded on a single machine. Your may see different results on your own devices due to:

• Different amount of flywheel dust or debris which alters drag factor;
• Air pressure differences, notably from differing altitudes, again impacting drag factor;
• Differing amounts of wear on machines.
