Thule makes numerous models that can take sixty pounds per slot. However, with 1.25" receiver, total combined weight of both bikes both not to exceed 100 lbs. If you have 2" receiver it is 120 lbs. I love mine, it was $449 and is on a Fusion Energi. I remove batteries and barely make the 100 lbs. limit.
The replacement or updated version of mine is the
Thule T2 Pro 9035 (
https://www.thule.com/en-us/us/bike-rack/hitch-bike-racks/thule-t2-pro-9035-_-1689770), it is a bit easier to use, but is $549. Not supposed to use with bikes with fenders, but like others I do with no problems. Very similar to a Kuat NV 2.
If your bike has fenders then you might want a Thule Easy Fold 9032, it is *gasp* $699 but a premium solution.
