You have the ability to change between three modes during a session using the Wattbike Hub.
Gear Mode – Is the default mode on your Atom, use the up and down buttons to change your gear. This mode is most like riding a bike
Gradient Mode – Set the gradient of an incline to ride to from 1 – 25% (micro adjustments of 0.5%) and the Atom will resist you to that gradient
Ergo Mode – Set a target wattage and your Atom will resist your training to that wattage regardless of your cadence
To switch between the modes, press the action buttons on the right shifter.
