Ok I am making a wheelless trailer or whatever ya call it first I bought two 2"x3"x8' 1/8" wall square tubing (on sale) and a 40" piece of 2"x2" 1/4"wall.
Then I measured my bumper and took into consideration that I wanted it to carry my sons 50cc honda so I just measured between the two plastic bumper ends it came out to be 4'5" which was good. I also didn't want to cause any problems with it sticking to far off the bumper so the width is going to be 24" so it is going to be 26" off the bumper. Day 1 so I dont have all the tools but I got stuff that will do the job so I cut the 2x3 into 4 pieces, two 24" end to end with 45 degree cuts on both ends the same with the longer pieces and made a box. Next I will make a piece that will keep it from swaying. Spent so far $6 for grinding wheels, $42 for tubing, so $48.

 

4+42=48??? jk, but my teacher made two of these things in hs and they were sweet, his would pivot, but i guess if its just for a 50cc then it should be cool.

 

yep 1+1= 4 what school did you go to? lol I allways have a couple brews after working, so math wasn't to sharp. yeah I did see the ones that folded up but i just want mine to hold Ninkasi and motorcycles. And I'll probably skate it to 2x3 is perfect for smiths and feebles.

 

I've always heard of these things being called cargo carriers. Ive got one for a moped. But how did your teacher's pivot? You mean like folding up or down, or pivot side to side when turning??

 

one side went down so you could just roll a bigger bike up on it. it had a spring pin and a latch it was cool

 

sounds pretty cool, the cargo carriers in lowes are like $150 so if you can do it for under 60 bucks BADASS
