It depends a great deal on the weight of the bikes you want to carry. Two road bikes provide a less than 50 lb load and two electric bikes can entail a 140 lb load on the rack. The better and stronger racks have been on backorder for months.
Thanks for the info...we need a rack that will tilt so that I can open the rear compartment...Rocky Mounts makes one that tilts & swings to the side..trying to find out if anyone has a tilt rack...
