A friend of mine made a comment about another friend of mine who used a rolling backpack
. Now, I have very little against rolling backpacks, but as my friend pointed out, they're dorky.
I set out to make a badass rolling backpack. I used about $70 in materials and it took about 4 hours to complete.
The backpack features pneumatic tires, so the ride is a lot quieter than a normal rolling backpack. The backpack is removable from the frame, it is bolted on using wingnuts. The frame is surrounded by 1" steel spikes.
