5.2. Adjusting Resistance
The bike features magnetic resistance, which is adjusted via a knob located on the main frame. Turn the knob clockwise to increase resistance and counter-clockwise to decrease it. This allows for a range of intensity from 0% (warm-up) to 100% (muscle stabilization).
To engage the emergency brake, press the resistance knob down firmly. This will bring the flywheel to an immediate stop.
