Sources and notes
What's listedFront lights, rear lights and rear radar for road and gravel bikes with a USD price on the brand's own store. Output, run time, radar range, mount, charging and weight are the brand's own words.
How we pickedSingle lights for road and gravel bikes, sold on the brand's own US store with a price on 21 October 2026: 18 front lights, 10 rear lights and 8 rear radar units (1 without a tail light). Magene sells from one global store priced in US dollars. Price is for the option the page shows first. Quotes are copied from that page, including its spec table (the grey label names the table row); "not stated" means it doesn't say. Lumens and run times are the brand's claims. Out: light sets and bundles, helmet-only and e-bike-powered lights (Garmin Varia eRTL615), lights the brand designs for the city (Trek Ion 100 R, Flare R City), anything sold out that day (Lezyne Mini Drive 400XL, Specialized Stix Elite 2 Taillight) and a page that prices two models as one (Magene AT1200/AT1600). Not every light on sale, so "cheapest" means cheapest here.
