Legal Notice and Terms of Use
Last updated: October 19, 2026.
Site owner
As required by Article 10 of Spanish Law 34/2002 on Information Society Services (LSSI), the details of this website's owner are available to anyone who requests them through the contact form.
Using the site
BikeRatio provides cycling calculators, guides and data free of charge and "as is." You can use them for personal and professional purposes without signing up.
Results are estimates
Results are estimates based on published formulas and on the data you enter. They don't replace the manufacturer's specifications for your bike, wheels or tires, a bike fit, or the advice of a mechanic, a coach or a doctor. Always stay within the maximum pressure ratings of your tires and rims. Information about bike laws is general information, not legal advice.
Intellectual property
The text, illustrations, design and code of BikeRatio belong to the site owner unless stated otherwise. Charts from our studies may be reused with attribution where indicated. What you create (your bike sheets) is yours.
Links
We link to third-party websites as sources or references and are not responsible for their content. Some links to stores are affiliate links (see our affiliate disclosure).
Limitation of liability
We do our best to keep calculations and data accurate and up to date, but we can't guarantee they're error-free. The site owner is not liable for any damage arising from using the information beyond its purpose as guidance. If you find a mistake, let us know.
Governing law
These terms are governed by Spanish law.
