Start with category coverage
RoyalBaby is listed for Kids, Mountain. Choose the bike category first because road, gravel, mountain, and kids sizing use different assumptions.
Check data status
Data sourced from official brand references. Use the result as a shortlist, not a final fit decision.
Confirm the exact model
Model year, geometry, wheel size, and cockpit setup can change the final answer even when the height range looks right.
