- Left-right power balance – Helps detect imbalances or injury recovery
- Seated vs. standing position analysis – Track how power changes across postures
- Power Phase – Identify the point in your pedal stroke where you apply the most power.
- Platform center offset – Insight into foot positioning and pedaling efficiency
These metrics are highly beneficial for performance riders, triathletes, and data-driven cyclists looking to refine technique.
