Terms of Use
Last updated 15 November 2026. Using Bike Speed Calculator means accepting these terms.
What the site provides
Bike Speed Calculator provides free cycling calculators for planning and education. Results are estimates produced by the published models described on the methodology page, from the inputs you supply.
No professional advice
Nothing on this site is coaching, medical, or professional advice. Power targets, training loads and race plans carry real-world risk; decisions with consequences — race cut-offs, rehabilitation, equipment safety — must be verified against official sources and qualified professionals.
Accuracy
I work to keep every formula correct and every default honest, and confirmed errors are fixed under the editorial policy. Even so, no result is guaranteed: models simplify, inputs vary, and conditions change. Check any number that matters before you rely on it.
Acceptable use
You may use the calculators freely for personal and commercial planning. You may not misrepresent the site’s results as certified measurements, or use the site in ways that break the law or interfere with its operation.
Liability
The site is provided “as is”, without warranties of any kind. To the fullest extent permitted by law, the site and its maintainer are not liable for losses arising from reliance on its estimates.
Changes
These terms may be updated; the current version and its date always appear on this page. Questions go via the contact page.
