I can confirm for you that the Swagman Chinook # S64683 weighs 47 lbs. This is a tilting and folding rack that fits 1-1/4" and 2" hitches, comes with an anti-rattle hitch lock and has a weight capacity of 45 lbs per bike. It holds your bike by the tube with padded ratcheting hooks and by the wheels with ratcheting straps.
I've added links to a pair of video reviews on this rack for you to take a look at as well. view full answer...
The bolts in the Curt Trailer Hitch Receiver - Custom Fit - Class I - 1-1/4", # C11473, are Grade 5. This is more than sufficient for the weight capacities of this hitch on your 2016 Toyota Prius. view full answer...
