Bicycles

A bicycle frame is typically made of hollow pipes rather than solid metal bars for several reasons. Firstly, hollow pipes provide a good balance between strength and weight, making the bicycle lighter and easier to handle. Secondly, the hollow design allows for internal cable routing, which protects the cables from dirt and debris, improving the bike's performance and longevity. Additionally, the hollow structure of the pipes can also help absorb vibrations and shocks from the road, providing a smoother and more comfortable ride for the cyclist.

Yes, there are frames that weigh less than a kilo. Not much point in them though. Racing rules require a certain weight, and the're too brittle for everyday use.

Well, honey, that all depends on how fast you pedal! On average, biking at a moderate pace of around 15 km/h, it would take you about 10-15 minutes to cover 2.4 km. But hey, if you're a speed demon on wheels, you might shave off a few minutes and arrive at your destination in record time. Just remember to wear a helmet and watch out for those pesky potholes!

A person who repairs bicycles is commonly referred to as a "bike mechanic" or a "bicycle mechanic." These professionals are trained to diagnose and fix various issues with bicycles, including repairing brakes, gears, chains, and wheels. Bike mechanics often work in bike shops or repair centers, utilizing specialized tools and knowledge of bicycle components to ensure bikes are in proper working condition.

Oh, dude, riding a mile at 5 mph on a stationary bike would take you a whopping 12 minutes. But hey, who's counting, right? Just pedal away and enjoy the virtual scenery passing you by at a snail's pace. Like, you might even break a sweat after all that intense effort.

The motion of a bicycle is in rectilinear motion, the object covers a certain distance along a straight line or a track. Whereas the motion of a ceiling fan when switched on is in circular motion, which is not moving from one place to another.

The circular motion of the wheel gives the bicycle a rectilinear motion and the periodical motion of a blade of a fan gives the fan a circular motion.

If marked in a point on the wheel of a bicycle or a blade on the fan, the distance between the centre of the wheel/fan and the marked point will remain the same as they rotate.

Well, well, well, looks like someone's got a math problem! If the wheel of a bicycle makes 1000 revolutions in traveling 628m, we can use the formula Circumference = 2 * π * radius to find the radius. First, we find the circumference by dividing the distance traveled by the number of revolutions. Then, we plug that value into the formula and solve for the radius. Voila, you've got your answer!

Because 17 speak neither, 100-17=83 speak at least one of those languages.

42+55=97

97-83=14, so 14 people spoke both.

During the Victorian era, a penny farthing bicycle typically cost around £10 to £20, which was a significant amount of money at the time. The cost varied depending on the quality of materials used and the manufacturer. The penny farthing was considered a luxury item and was primarily owned by the wealthy elite.

That'd be a quadricycle or a quadra bike or something like that. Maybe even a pedal car.

Up to 1.85 metres (approx 6' 1") for an adult road bike

Well, honey, Baron Karl von Drais was more of a doer than a talker, but if you're looking for a quote, here's one for you: "Four wheels move the body, two wheels move the soul." And that's about all the wisdom you'll get from the father of the bicycle.

Triumph Street Triple

Very much not just a mini-Speed triple, the 675cc Street is a smaller, lighter, more manageable kettle of fish. Sadly, said fish will probably all fall out within half a mile as you pull massive monos everywhere. Seriously, it's the easiest, most fun roadbike to wheelie there is and a great road bike to boot.

Another KTM but that’s because the Austrians make incredible wheelie bikes. The Supermoto 690 SMC R is everything you want from a wheelie bike -a lightweight machine with a punchy, torque-fest single cylinder motor. Thanks to modern electronics and engineering, the later models (2019 on) are ridiculously smooth for a single and although aren’t very practical for longer runs, they will leave you smiling after every ride. The Husqvarna 701 is pretty much the same bit of daftness.
