When you have plenty of bicycle to work with, such as is the case with a mountain bike, it’s not such a big deal to design it with front and rear suspension. When the bicycle in question is a diminutive folding city bike, however, it gets a bit trickier. That’s why UK industrial designer Sam Pearce has created Loopwheels. Instead of relying on a suspension fork and rear shock, it lets the bike’s 20-inch wheels absorb the bumps.
Some of the most important parts of a car’s suspension system include tires, shock absorbers or struts, arms and bushings, ball joints, coil springs, and stabilizer bar link. Like most parts on the car, the shock absorbers and/or struts need to be checked regularly as part of the service schedule of the car. • Frequency of regular maintenance such as chassis lubrication and wheel alignment

To restrain cars from rolling - leaning over on corners - an anti-roll bar is used, often at the front, sometimes at the back and sometimes at both front and back.
