Two different rules, and it is worth knowing which one applies to you. Technical diagrams and schematics (the SVGs) are free under CC BY 4.0: use them, translate them, upload them to Wikipedia — just cite. Workshop photographs are our own work and are reserved: for those, write to us. For academic use the authorisation is free.
© 2026 BikeLab Studio — All rights reserved.
The images, figures, diagrams and photographs published on this site are protected. Their reproduction, adaptation or republication requires written authorisation. We do grant licences: write to us and we will arrange it. Last updated: 14 August 2026.
Unless otherwise indicated, the images and figures are the intellectual property of BikeLab Studio, created by Carlos Eduardo Ravello Joo (ORCID 0009-0007-5631-7436) at the laboratory in Trujillo, Peru.
Each file carries this authorship data embedded in its metadata (IPTC / EXIF / XMP / Dublin Core), so that the origin information stays inside the file even if it is downloaded and used away from this site.
Indexing and citing, yes. Training models on them, no.
It is not a “no”. It is an “ask us”. We answer quickly and in most cases we say yes — we just want to know where our work ends up.
To reproduce a figure in academic work, write to us: the authorisation is free and we give it by email.
Many of these figures accompany datasets and technical articles with a permanent DOI; in that case, cite the article and its DOI in preference. Suggested format:
Citing the figure in the bibliography never needs permission. What needs it is the reproduction of the image.
The technical diagrams, schematics and cross-sections published in SVG format —those of the BikeLab-pedia and those of the articles— are published under Creative Commons Attribution 4.0.
You may reproduce, translate, adapt and republish them —commercially too— on the single condition of citing the source. No need to ask us or to let us know.
This is deliberate, not an inconsistency: a diagram that explains something well is worth more circulating than locked away. Each file carries its authorship embedded in its RDF metadata block (Dublin Core + Creative Commons), and since SVG is plain text, that authorship is not lost when the file is opened or converted: it has to be deleted by hand, and deleting it breaches the licence condition.
Go ahead, and thank you. The diagrams are under CC BY 4.0 precisely so they can go into Wikimedia Commons, which only accepts free licences. The attribution you need is this:
If the diagram accompanies an article with a DOI, cite the DOI too: it is the identifier that does not break even if the URL changes.
Mind the difference: the diagrams are free, the photographs are not. A drawn schematic explains a concept; a workshop photograph documents a specific case, with its bicycle and its owner. The first is shared; the second is asked for.
The data deposited in Zenodo with a DOI —the 132 calibrated MTB suspensions, the 47 new bicycles and the 321-tyre census— are published under CC BY 4.0 together with their methodology.
You may download them and make your own figures with them, publish those wherever you like and cite us for the data. What is reserved is our graphic representation: the specific diagram, with its design and its labelling.
Put another way: the numbers are yours to use; the drawing we made with them is not.
The brand and logo of BikeLab Studio are not covered by any permission and may not be used in a way that suggests endorsement or affiliation.
The portrayal of identifiable people requires their own consent, outside these terms.
Removing or altering the authorship metadata to hide the source is not a covered use.
Photographs featuring Keily Sánchez are published with her consent. She is the égérie of BikeLab Studio, not the author: authorship of the images belongs to Carlos Eduardo Ravello Joo. Her personal image is hers and is not covered by any licence on this site: any use of a photograph in which she appears requires her own permission in addition to the author’s.

Every figure on this site came from a real bicycle, from a measurement taken with an instrument and from a model that had to be validated against a numerical oracle. We do not mind it being used — we mind it being used as if it had cost nothing.
Ask for it and it is yours.
