Who invented the bicycle?

User Avatar
James Starley is the father of the industry of the bicycle. There are several people credited with the invention of the bicycle including Kirkpatrick Macmillan and Pierre Michaux. American, Sylvester Howard Roper (1823-1896) invented a two-cylinder, steam-engine motorcycle (powered by coal) in 1867. The first vehicle that was invented that can be considered "bike like" is the "draisines" invented by Karl Drais in 1817. It had two wheels and a steering handlebar, but no pedals. It essentially worked like a scooter where someone would run while straddling the machine and then allow it to coast the rest of the way. The pedal crank wasn't added to what we now know as the bicycle, then called the "velocipede", until the 1860's in France. These bicycles were direct drive though. The "safety bicycle", from 1876 and invented by British engineer Harry John Lawson, is the antique bicycle most like what we ride today, but a treadle (a treaded belt) drove the rear wheel as opposed to a chain. Bicycles as we know them today, with a crank driven chain drive, weren't introduced until 1879, but they weren't commercially successful until John Kemp Starley, also British, came out with his "Rover" bicycle. Because of the commercial success of the Rover and the "bike boom" that soon followed, Starley is often credited as the inventor of the modern-day bicycle. The early model that the rider had to propel forward by a 'walking' motion of his legs was called the Draisienne. It was built by the German Karl von Drais. The first 'modern' bycicle with a crank and pedals was built by Frenchmen Pierre Michaud and Pierre Lallement.

How do you learn to ride a bicycle?

User Avatar
Answer Start by finding a bicycle where the saddle can be lowered enough so that you can reach the ground with both feet while seated. Make sure there's a working hand brake. Pull the pedals off. Remember that the left pedal has a reverse thread. It comes off clockwise. Find somewhere flat, and out of the way. A gentle slope will work too. Straddle the bike, and walk/run/kick your way forward by pushing off against the ground with your feet. Practice your balance by taking longer and longer strides. When you are comfortable doing this, reinstall the pedals. Find a gentle slope. A lawn is ideal. Put one foot on a pedal, kick off with the other one. Get the other foot in place and start pedalling. Now you're riding. When you're OK with this, raise the saddle. When seated, your leg should be entirely straight if you put the heel on the pedal in its lowest position. When riding, the pedal should be under the pad of your foot. Study the Rules of The Road for cyclists. Enjoy your new freedom. Answer Begin with two stabilizers, then one, then none. how old are you? if you're a 5th grader abd below.. it wouldn't be bad if you start with trainer wheels :D just keep trying and trying and trying until you get the hang of it that's how i did it.

What is granny gear?

User Avatar
Granny gear is a term used for truck manual transmissions extremely low first gear.This type of transmission would be one that when driving normally around town you would start out in second gear.the very low gear reduction of the first gear would be used for low speed pulling or crawling where the extra torque is needed. ANS 2 - Granny gear is also used in bicycles. On any bike with three chainrings, the smallest, innermost ring is often referred to as the"granny", or the bailout gear. Having to drop to the smallest chainring is often seen as the last resort before having to get off and push the bike, if the incline gets too steep for any of the "regular" gears.

What is the volume of air in a bicycle tire?

User Avatar
The answer to that would differ a lot depending on what tire you're thinking about, and what the pressure is. Tires come in very different sizes, with very different volumes.

How old do you have to be to not have to wear a helmet?

User Avatar
The laws for helmets and bicycle riding are different from place to place, so w/o knowing where you are the question can't be properly answered. Some places, you are free to choose when you're 15. Other places require all riders of all ages to wear helmets. But ignoring the law, anyone who thinks their head is worth protecting should wear a helmet regardless of age.

Asked in Bicycles

What are the main differences between the penny farthing the safety bicycle and the modern bicycle?

User Avatar
The penny farthing had no gearing between the pedals and the front/drive wheel, so the front/drive wheel had to be made really big to get any speed out of the bike. Then the rider had to sit nearly straight above the wheel axle to be able to steer and pedal. This made the bike prone to toppling forward while braking. The safety bike had a chain between the pedals and the rear/drive wheel. By having a bigger sprocket by the pedals and a smaller at the rear wheel you could get the bike up to speed while still retaining a more practical wheel size and placing the rider between the wheels rather than on top. This meant you cold break with much less risk of toppling forward, hence the name "safety bike". The modern "utility" bike is in principal very similar to the safety bike. It is most likely lighter, has better brakes and the ability to freewheel; it might have any number of gears, but the basics still remain. Today we have all manners of specialized bikes, full suspension MTBs, flimsy road bikes and everything in-between.

Why does a bicycle wheel spin more freely if it is oiled regulary?

User Avatar
Oil is good for a short period, then it's not so good. Oil does two things that make it not appropriate for wheel bearings, it tends to run right out after being applied, and it attracts dirt. Dirt causes wear. For wheels, waterproof grease would be the product of choice. Personally, I find Phil Wood grease to be the best.

What polymers are used in bike tires?

User Avatar
Kevlar (Aromatic Polyamides) is used in tire reinforcement. Polybutadiene (Butadiene Rubber, BR) is used for the carcass and side wall. Natural rubber is a polymer, and they put polyurethane in tire rubber too. While aramids like kevlar are often used in car and motorcycle tires, nylon (less expensive and works fine) is used in bicycle tires.

The overwhelming majority of bike chains are made of steel alloys, although a few are made of titanium. Bike chain is made of tempered hardened steel. Metal Primarily steel. It's strong enough, wear resistant enough, cheap enough, and easy enough to machine and shape.

My boyfriend recently bought one of these for me. The company seems new but the product came exactly as advertised - Colorful, simple, design-centric, and affordable. I/he did a lot of research on cheap fixies and this company (based in los angeles) seemed the cheapest. So far, i love it and can confidently say, yes, it's a good fixed gear bicycle.

How do you tell what size bmx pedals you need?

User Avatar
1 piece cranks need the 1/2 inch pedals while 2-3 piece cranks use 9/16th. Just to help the newbies out there. OPC or one piece cranks mean the arm that holds the pedal is just one piece of steel that goes from pedal to pedal through the bottom bracket (where the bearings ride). Those only use ½" size threads on the pedals. 3 piece cranks are identifiable as each arm is separate and bolted onto the spindle which is part of the bottom bracket. 3 piece refers to 2 arms + the bottom bracket. Only 9/16" (which are bigger than the ½") threads fit those arms. Don't forget the left arm is backwards thread, so to loosen you turn it righty tighty. The right arm is normal so lefty loosy to remove.

What is the best crank size for your mountain bike?

User Avatar
Extensive research has shown that there is surprisingly little difference in rider performance between different crank lengths. The most common crank size is 175 mm, and unless you hve a specific issue with thet there is very little to gain by swapping it out. Or are you actually asking about suggestions for crank/chain ring sizes - tooth counts?
