More importantly what is the per bike weight on that rack? The total rack capacity doesn't matter it is all about the per bike weight. If you are noticing a lot of swaying keep in mind it is a low initial cost rack so it might sway or flex more especially when super close to limits and definitely if over the limits. I would remove your batteries and that might help a bit. Also keep an eye on rust and any damage to parts it is a safety item first. When it fails it could be extremely dangerous 60lbs plus 2 75lb bikes is a lot to go flying into a car behind you. When we sold them they had rust issues and hopefully they have found a good powercoater instead of painting them but even if a good rack it is still important to keep a close eye on it.
