Bike Helmets dataset — license & sample
One CSV/XLSX/JSON bundle: 16 product records, 33 fields, per-value provenance.
Quality tier: lite.
How buyers use this bundle
Typical uses: build a filterable shortlist by brand or spec threshold, compare a client's
catalogue against the market, or cite a specific value in a report. The bundle keeps source_url,
qa_flags and a provenance file so any number can be traced back to its page and quote before it is
used in a decision. Fields with low coverage are null rather than guessed; the data dictionary shows coverage
per field so a buyer can see exactly what is complete.
