All of the sheet metal is 1/4" aluminum. The 2 outer tubes re 1.5" square by1/8" thickness. The inner cross braces are 1" square by 1/16" thick. The everything pictured including motors and gears weighs 32lbs. The only thing left is chain and a few bolts. You need to get in touch with me and we’ll figure something out for you guys.
I would suggest making slots for where you mount the front and rear wheels, so you can adjust chain tension. It will make it a lot easier when all you have to do is pull it tighter to tighten the chain.
One thing that you cant see well in the render is the tensioning device. it is an axle with a sprocket on it between each wheel that we tighten 2 screws and it raises the axle, thus tightening the chain. This past season we did the slots for the wheels for tensioning and although it worked well, it required removing bumpers to tension. The new system does not require removing anything. So for a small weight gain we save a lot of time during competition.
