The weight limit is to keep fat guys like me off of it. If you throw 50 lbs of bikes on there bouncing down the road you will work everything loose.
I dont know where you are but most every town has a welding shop. Go visit them. I bet for a few hundred bucks they can custom fab a bike rack to fit your needs.
