Thule Apex XT Swing 4

The swing-away design is the selling point — full trunk access with four bikes loaded, which most four-bike racks cannot do. At 42 lbs it is remarkably light for a four-bike rack. The trade-offs are the 37.5 lb per-bike limit (no e-bikes), hanging design that contacts frames (not carbon-safe), and steel construction. Integrated locks for bikes and hitch. I recommend this to families with four standard bikes who need trunk access at the trailhead without unloading everything.
