E-bike data notes

A reading guide to the e-bike build: what it contains, how concentrated the brand coverage is, which battery and drivetrain fields are complete, and what the inventory tier does and does not promise. All numbers are computed from the current bundle (v2_20261115); they are descriptive, not forecasts.

What this build contains

The bundle has 365 models from 32 brands, with 100.0% of populated values carrying a source URL, quote and fetch time, and 0% of rows carrying at least one non-price spec field. It mixes 87 curated full-spec records with 278 catalog-derived records (price plus whatever specs the storefront published); missing values are null, never guessed. Quality tier: inventory.

Price and brand concentration

Listing prices: median $1,699 (P25 $1,099, P75 $2,499, n=365). The largest collections are Scooteretti (37), Engwe (31), Biktrix (30), Lectric eBikes (29), Rad Power Bikes (16); the top brand (Scooteretti) accounts for 10.1% of records, so the build is a broad slice of the catalog-derived market rather than the full category census.

Battery, motor and weight coverage

These are the fields buyers filter on most; coverage below 50% means a spec is missing on more than half of the rows and should be treated as a filter rather than a complete column.

Quality and limitations

This is an inventory build: the gate requires at least 200 models, 75% price coverage and 45% battery-Wh coverage, and the provenance gate is 80%+ (observed 100%). 278 record(s) carry QA flags (for example, advertised Wh that does not match voltage × Ah); 0 record(s) have no listed price and are excluded from price analysis. Prices are snapshots at the fetch date recorded per value.
