Yakima DoubleDown 4

Four bikes at only 20 lbs with tilting capability and dual hitch compatibility — that weight-to-capacity ratio is remarkable. Folds down when not in use. The trade-offs are 35 lb per-bike limit (lightest bikes only), no bike locks, frame-contact design (not carbon-safe), and no e-bike support. I recommend this to large families on a budget who carry lightweight bikes and want the easiest possible rack to install and remove regularly.
