The bicycle was introduced in the 19th century in Europe by German Inventor Karl von Drais. He is credited with developing the first bicycle. He introduced it to the people in Paris in 1818. It is supposed to originate from the human-powered vehicle called Draisines. Drais invented a walking machine that would help him get around the royal gardens faster. It was known by many names, including the “velocipede,” “dandy horse,” “hobby-horse,” “draisine” and “running machine. It had no pedals and its frame was a wooden beam. It had two same-size in-line wheels with the front one steerable and mounted in a frame which was straddled. In 1839, Kirkpatrick MacMillan, a Scottish blacksmith, allegedly completed construction of a pedal driven…

Commuting by bike is made more comfortable by riding with the optimal tire pressure. Beginners will need to know where on the tire to find the manufacturer’s recommended amount of inflation. From there, they can work towards finding a sweet spot which could change based on different surfaces and riding conditions. What Pressure Should My Bike Tires Be? Bicycle tire pressure is measured in PSI (pounds per square inch) or in bar (from the ancient Greek word for weight). Bike tire pressure should be within a measured range noted on the side of each tire. Manufacturers set this to prolong tire life and acknowledge different rider characteristics. It’s not unreasonable to start with a tire pressure in the mid-range of…

Bike tires (or tyres) lose air more rapidly than vehicle versions due to size, shape, material, and a constant pressure forcing air out of them. The day-to-day hazards of punctures are easier to identify, so it can be frustrating to have to re-inflate a tire that felt firm the last time you rode. What Causes a Flat Bike Tyre? Punctures from surface debris, poorly inflated tyres, worn or cracked tyres, plus constant pressure forcing air out of any gaps in the rubber compound and valves are the main cause of a bike tyre going flat. Day-to-day, a tyre will lose pressure despite efforts to keep it all in. The tyre is our only contact point with the surface so we…
