Six-bike capacity is rare and this is one of the few quality options at that number. Swing-away design for trunk access, anti-sway cradles, 55 lb per-bike capacity for e-bikes, integrated locks for everything. At 87.4 lbs this is a two-person install, no question. Steel construction is durable but heavy. I recommend this to large families, bike clubs, or shuttle operators who genuinely need to move six bikes at once — do not buy this for two bikes just because you might need six someday.
