I probably wouldn't trust that rack to hold much of anything. There are good racks out there from real companies that you can get from your local shop that won't be much more than that thing (or maybe even the same price) but will be a solid well made rack with proper mounting points and will likely weigh less. Topeak, Axiom, Delta, Planet Bike...all make fine racks that aren't as complicated and cheaply made. Plus if something does happen they will support you more than some fake Amazon/Alibaba and his 40 thieves brand is going to do. There are even other no-name racks from the Billionaire Bezos that look better than that one at basically the same price, I am not recommending any of them just noting that some look better. However there are also a lot that claim ridiculous carrying capacities which would beyond overload those racks and are more weight than I would carry on my Tubus rack which I would actually trust to be able to carry those weights once some of which are double the capacity and look flimsier than a sheet of loose leaf paper in the wind.
