1418 -Giovanni Fontana is credited with building the first human powered land vehicle -- it had four wheels and used an continuous rope, connected via gears to the wheels. Images and more detailed description don't seem to exist.

1791- Comte de Sicrac is credited with building the "celerifer" - purportedly a hobby horse with two wheels instead of a rocker. This is now considered a patriotic hoax created by a French historian in 1891. It was debunked by a French researcher in 1976. In fact, a Jean Sievrac (!) of Marseille obtained an import price for a four-wheeled speed coach called celerifer in 1817.
8 Ways Cycling Will Make You Healthier.
A study conducted by Charles Hillman back in 2007 showed that exercise boosts brainpower and helps to stave off Alzheimer’s in the elderly. That same year, Dr. Phil Tomporowski showed that kids are even more positively impacted by time on the bike—and that exercise can help control issues like ADD. (Read one cyclist's account of how riding helped him manage his ADHD.)
2)Improve Your Heart
Cycling is also great for your heart—although not just because you love riding so much (though that’s a great reason too!). A recent study in Medicine & Science in Sports & Exercise spent five years looking at the activity of 1,500 subjects. Those who were active on a daily basis were 31-percent less likely to develop high blood pressure.
It shouldn’t really come as a surprise that weight loss is one of the big benefits of regular cycling, but it bears repeating. The media is often quick to promote the idea that diet is the only way to actually shed fat, but science is proving otherwise. A recent study showed that older, diabetic women could only drop visceral fat if exercise, along with diet, was introduced into their routine. The same was proved true for younger women.
According to one study of Tour de France riders from the past, cycling actually increased their longevity. On average, the former pros lived to 81.5 years compared to the general population’s 73.5 years: a 17-percent increase! Anther study suggested that even casual bike commuters benefit: For individuals who shift from car to bicycle, it was estimated that three to 14 months could be gained compared to the potential downsides of bike commuting.
5)Feel Better About Yourself
It’s no surprise that exercise in general (and cycling in particular) helps improve your self-esteem. The next time you take the perfect mid-ride selfie, score that Strava QOM you’ve been chasing, or finish a really hard workout, your body will release a whole bunch of feel-great hormones that will make you feel like you can take over the world.
6)Help Prevent Cancer
Maintaining a healthy weight, regular exercise, and a conscientious diet (think lots of leafy greens, lean proteins and healthy grains) all helps lower your risk of cancer. And a study published in the Journal of the American Medical Association recently looked at nearly 14,000 men and concluded that those with a higher fitness level as they approached middle age were at a lower risk for lung and colorectal cancer.
Best news ever: You aren’t the only one who thinks spandex is super hot. A survey of 600 men and women commissioned by The British Heart Foundation found that cyclists were perceived as 13-percent more intelligent and cooler than other people, and a whopping 23 percent said a cyclist would be their preferred blind-date athlete.
8)Recover From Injury
A recent study found that elderly patients with knee pain and osteoarthritis actually improved their condition when cycling was introduced to their routines, proving that as we get older, taking time to exercise—even just spinning a few minutes a day—can be hugely beneficial.
Riding a bike can help you lose weight, recover from injury, and even get smarter—and that's just for starters
