This Yakima "Full Swing" bike rack carries 4 bikes securely. This is a perfect bike rack for families! The beefy construction ensures bikes are securely mounted, even when the rack swings completely away from your tailgate, trunk lid or hatch while the bikes stay mounted on the rack. The tongue of the bike rack fits into a 2 " square trailer hitch mount, and the knob that tightens the tongue into the channel has a lock to prevent thefts. The bike rack arms can be lowered when not in use. This rack sells new for $700.
