And not just because you're grandma doesn't own a quadricycle, but it's probably best she not do any pedaling considering her crystalline hips and all. So, yeah, the BigDog Quadricycle: a bike that won't hesitate to tear your balls to shreds and ride over them if you ever get a pant leg stuck in the gears. Safety first! (Wear shorts)
Measuring 11 feet, 4 inches long and 8 feet high, this crazy ride uses go-kart brakes and axles and recycled bike parts to get you on the road. Apparently those outer rims are parts of a drainage pipe, so you know it's nice and sturdy.
Pretty neat. As far as I can tell it's only missing one thing: a motor. What? I have chicken legs, okay?! Kidding, these things are like oaks. AND NO ACORN JOKES!
Several more shots and a video of the bike in action (with flames!) after the jump.

Thanks to Robin, whose quadricycle sadly became a tricycle after an unfortunate run-in with a curb.
