Thule Helium Pro 3

Three bikes at only 20 lbs — that weight-to-capacity ratio is unmatched. Aluminum hanging design with anti-sway cradles and tilt-away. The trade-offs for that light weight are a 37.5 lb per-bike limit (no e-bikes), frame-contact cradles (not carbon-safe), and no fold-flat. Integrated locks for bikes and hitch. I recommend this to families who remove their rack frequently and do not want to wrestle with a 60+ lb platform rack every weekend.
