The History of the Folding Bike
History[ edit ] The spoked wheel was invented to allow the construction of lighter and swifter vehicles. The earliest known examples are in the context of the Sintashta culture , dating to ca. Soon after this, horse cultures of the Caucasus region used horse-drawn spoked-wheel war chariots for the greater part of three centuries. They moved deep into the Greek peninsula where they joined with the existing Mediterranean peoples to give rise, eventually, to classical Greece after the breaking of Minoan dominance and consolidations led by pre-classical Sparta and Athens.
Celtic chariots introduced an iron rim around the wheel in the 1st millennium BC. The spoked wheel was in continued use without major modification until the s, when wire wheels and rubber tires were invented.
Dating back to the days of the Winking Circle in Uxbridge, Ontario, I’ve always been intrigued and inspired by the Zenga it kind of blew my mind that after moving to Vancouver in , I’d find myself living around the block from some of these brothers and their wild .

History of the bicycle
The company history began more than one hundred years before then, in a time and in a Europe that would be wholly alien to those of us brought up over the recent generations. To be concise, the origin was some decades before then in when Josef Werndl b. He improved manufacturing techniques and diversified their offerings.
They would continue the manufacturing but also develop the Werndl-rifle Model , a new modern breech loading rifle system. Working with talented engineers including Ferdinand Mannlicher the company became the leading European producer of small arms. The company began producing bicycles in , and “Steyr” brand automobiles in

Replica made from the alleged Caprotti sketch. There are several early but unverified claims for the invention of the bicycle. The earliest comes from a sketch said to be from and attributed to Gian Giacomo Caprotti , a pupil of Leonardo da Vinci. In Hans-Erhard Lessing described this as a purposeful fraud. Augusto Marinoni, a lexicographer and philologist, who was entrusted by the Commissione Vinciana of Rome with the transcription of Leonardo’s Codex Atlanticus.
Drais invented his Laufmaschine German for “running machine” in , that was called Draisine English or draisienne French by the press. Karl von Drais patented this design in , which was the first commercially successful two-wheeled, steerable, human-propelled machine, commonly called a velocipede , and nicknamed hobby-horse or dandy horse. Hans-Erhard Lessing Drais’ biographer found from circumstantial evidence that Drais’ interest in finding an alternative to the horse was the starvation and death of horses caused by crop failure in , the Year Without a Summer following the volcanic eruption of Tambora in This design was welcomed by mechanically minded men daring to balance, and several thousand copies were built and used, primarily in Western Europe and in North America.
Its popularity rapidly faded when, partly due to increasing numbers of accidents, some city authorities began to prohibit its use.
Larger Image The name says it all – the top of the Schwinn line. Schwinn today is part of Pacific Cycle. While Schwinn often had a reputation for building heavy bikes for kids, the Paramount line had a reputation for finely crafted, relatively light road bikes. That is obviously a great price.

Some of the mid ‘s straight guage frames had serial numbers starting with a single letter which was towards the end of the alphabet. This new system applied to the high-end i. Reynolds frames, and involved the placing of a character at the beginning of the serial number. The character began at the start of the alphabet, and indicated year of manufacture. Detail about the numerals that follow the alphabet are sketchy, and are presumably sequential serial numbers of some kind.

Share shares Four years ago the initial concept was created in the Netherlands, now the Utrecht-based firm is distributing the bikes to several countries, including the United States, Mexico and the Caribbean. It uses a motor to assist the treadmill, so using the bikes takes little effort. Sensors register the turning treadmill and kick the motor into gear to assist. The bikes can travel 30 to 50 miles on a charge and gears enable the user to change the pace.
It can achieve speeds between 4—17 mph 6—27 kph.

Contact The History of the Folding Bike There have been many who have laid claim to the invention of the folding bike. Humorously, a bike manufacturer who shall remain nameless so as to not unduly embarrass them audaciously claims on their website to have produced the world’s first folding bike in Wishful thinking by their marketing department I suppose. The truth is that the folding bike has been around for considerably longer than one might imagine and most claims of being the first are erroneous.
First things first though, you can’t have a folding bike without the invention of the bicycle itself. So a very short history lesson on the bicycle is in order. Here again we have some disputed claims of invention and historians will probably never be able to identify the exact moment of invention. For a while some had claimed that Leonardo Da Vinci invented the bicycle based on a sketch found in his Codex Atlanticus.
However, this sketch was later determined to be a forgery, though many historical accounts written before this forgery was discovered still credit Da Vinci as the inventor of the bicycle. There were a few “pre-bicycles” invented before the appearance of what one would recognize as a bicycle. The first of these was probably the “Celerifere” developed by a French count named Mede de Sivrac in It consisted of two wheels connected by a beam and was decorated to look like a horse or a lion.
There was no steering mechanism or pedals and it was basically a whimsical novelty meant to entertain the idle rich.

Opinions and value judgments are our own, unless otherwise noted — Sheldon d. Additions and corrections are most welcome. Sachs also made multi-speed internal-gear hubs in 3-, 5-, 7- and speed versions. Their “3 x 7” hub was a hybrid system, a 3-speed internal hub that took a 7-sprocket cassette, providing 21 speeds with only one chainwheel. Sachs formerly also made kick-back hubs and a “2 x 6” hybrid hub, the “Orbit”.
The one clear area of domination for Sachs was its chains, which were generally acknowledged to be the finest available.
Frames were normally manufactured the year before being sold in bike shops. So a build date on a frame of usually means the bike was sold in stores in This is the case with the Mongoose Brawler 24 below.
The first known traffic signal appeared in London in near the Houses of Parliament. Designed by JP Knight, it featured two semaphore arms and two gas lamps. The earliest electric traffic lights include Lester Wire’s two-color version set up in Salt Lake City circa , James Hoge’s system US patent 1, , installed in Cleveland by the American Traffic Signal Company in , and William Potts’ 4-way red-yellow-green lights introduced in Detroit beginning in New York City traffic towers began flashing three-color signals also in Garrett Morgan’s cross-shaped, crank-operated semaphore was not among the first half-hundred patented traffic signals, nor was it “automatic” as is sometimes claimed, nor did it play any part in the evolution of the modern traffic light.
Gas Mask Garrett Morgan in ? The invention of the gas mask predates Morgan’s breathing device by several decades. Early versions were constructed by the Scottish chemist John Stenhouse in and the physicist John Tyndall in the s, among many other inventors prior to World War I. Peanut Butter George Washington Carver who began his peanut research in ? Peanuts, which are native to the New World tropics, were mashed into paste by Aztecs hundreds of years ago.
Evidence of modern peanut butter comes from US patent issued to Marcellus Gilmore Edson of Montreal, Quebec in , for a process of milling roasted peanuts between heated surfaces until the peanuts reached “a fluid or semi-fluid state. Louis, manufactured peanut butter and sold it out of barrels. Kellogg, of cereal fame, secured US patent in for his “Process of Preparing Nutmeal,” which produced a “pasty adhesive substance” that Kellogg called “nut-butter.
