I have been contemplating adding a bike rake on the back of my 13' Love Bug
. I know that the rear bumper is not rigid enough to take the twisting of a bike rake so I was going to fabricate an additional support similar to a reciever hitch.
I would add a cross brace about 2 feet in front of the bumper then weld my reciever tube under the bumper and under the cross brace. This would eliminate the twisting of the bumper.
I am not overly worried about the weight
of my bikes being supported vertically by the bumper, just the twisting of the bumper. I have basket that goes into the reciever for carrying objects that I don't want in my van, such as a gas can and chain saw. If I keep the load light
, I may use that on the back of the trailer also. (My wife hates the smell of gasoline.) I plan on a max weight of 50 pounds on the back hitch and can eliminate hitch weight problems by changing my interior loading.
