Rollout measurement record
Enter three measured distances for one complete wheel turn. Use millimetres and the same setup for each measurement.
Mean = sum ÷ 3. Spread = largest − smallest. This record does not certify measurement accuracy or prescribe a tyre pressure.Gear development
Calculate theoretical distance travelled per complete crank turn using your measured wheel circumference and actual tooth counts.
Development = circumference ÷ 1000 × front teeth ÷ rear teeth. No cadence, effort, speed target or component compatibility is recommended.Delivered bicycle quote
Enter seller-confirmed AUD amounts with taxes already included. Include assembly only when it is a separate charge. Enter zero for a confirmed free item.
Total = bicycle + separate assembly + accessories + delivery. This adds your inputs; it does not retrieve a live price, add tax or determine your consumer rights.
