Loopwheels come in front- and rear-specific versions, one of the key differences being that the springs in the front wheel are twice as compliant as those in the back. This is (presumably) to help keep the wheel that does the steering from being knocked and bounced around, plus it compensates for the fact that more of the rider’s weight tends to be centered over the rear wheel.
Take the mammoth Caterpillar 797F Mining Truck (pictured above), which stands more than 25 ft (7.6 m) tall and weighs in at 1,375,000 lb (623,700 kg). Each of the big Cat's six monstrous 59/80R63 tires stands over 13 ft (4 m) tall, weighs about 12,000 lb (5,440 kg) and costs somewhere in the range of US$38,000 each.

The right pedal just fell off while ridding and it won’t go back in, its as if it lost its ability to screw in its socket (it looks more like an issue with the socket and not the actual pedal).
People out there lucky in the sense that they know how to ride a bike but unlucky in the sense that doing so jars their spines and brains and generates great discomfort in the crotchal region, say hello to Loopwheels. Loopwheels are 20" bicycle wheels with built-in spring systems between their hubs and wheel rims that provide suspension and cushioning from road bumps and potholes. So that everyone who finishes a Loopwheeled bike jaunt does so with lumbar vertabrae, tailbone, and rectum as intact as they were before the ride began.
