Heck yeah, let's kick the tires and light fires!
Guy Builds Bicycle With Off-Road Truck Tires

Because why the hell not, this is a video of Youtuber BigWR building a bicycle with off-road truck tires. Now I can see all those gears there, but I still don’t think my calves would be able to pedal this ting. Or whatever parts of my legs do the pedaling. Quads? Butt? My point is I don’t think I would be able to do that and I’m tired just watching.
