Portal Forums Photo Gallery. Fastest Whizzer. Some storys are just fun Roger Brophy is a friend, old trials rider and vintage motorcrosser. Thought some of you would like this. Having discovered their mutual interest in vintage Whizzer motorbikes through an exchange of E-mail, Brophy took charge of the chassis and Thomas built the engines for a spindly speedster pictured here that they named Double Vision.1kz te cracked head
Double Vision's powertrain consists of two cc Model J Whizzer engines with high-compression heads, Carter carbs, Weber cams, and one-inch valves, coupled together with a V-belt primary drive and chain drive to the inch rear wheel and Cheng Shin x 26 mountain bike tire. The chassis is a single loop of mild steel tubing with a 60 inch wheel base and Peugeot moped front forks.
Brophy ran a similar machine at Bonneville inrunning 52 miles per hour. We did this with a couple of boxes of 60 year old parts, some bicycle components, and a little back yard ingenuity.

Mar 15, 1 0 Guthriesville Pa. I need a little more info. Basically I need to know what year Whizzer you want to modify. The vintage motors and the later models look similar but are very different. Quenton Guenther Dealer. Feb 21, 1 0 Outer Banks of North Carolina. Hi militarymonark, There are many modifications to enhance the vintage Whizzer motor. The "H" motor is slightly more difficult to extract power because of the smaller ports. Remove the "island" in the combustion chamber.
Open the intake and exhaust ports.By June of Whizzer figured they should have a complete unit of their own. They began to produce a cantilever type frame " in house", and equipped it with a Whizzer designed motorcycle style telescoping spring fork and with 24 inch Lobdell wheels. Sold complete with the new "J" engine, this was called the "Pacemaker". While the frame differed somewhat from the Schwinn design, apparently there was enough similarity that a patent fight ensued.
After the first Pacemakers, Schwinn produced the balance of the frames. Bob Baker says he has never seen a Whizzer produced Pacemaker frame with a serial number above June, We just came across number It is definitely a Whizzer frame, and has a Schwinn Springer. The Pacemaker was offered at least up to See the article by Leonard Davis. In November Whizzer introduced a 20 inch model. Too low to have pedals, it was equipped with a kick- starter. This is the "Sportsman" ; with the "S" engine.
It was an "in house" produced bike. There is some documentation that Schwinn built the later frames.
1951 Whizzer Pacemaker
In a 24 inch version, called the "Ambassador" ; was produced. It was equipped with the "s" series engine. There were at least "Sportsman" and "Ambassador" models produced. There was also a Service Pickup, which was a "spin off" of the Sportsman, with a frame extension over the rear wheel on which were mounted two metal tool boxes and a tow rig.
The bike, with the front fork locked, could be towed backwards behind an automobile, with the rear wheel off the ground. It was intended to be used by auto mechanics in the pickup and delivery of customer's vehicles. Unfortunately, the lack of operable bicycle pedals makes them a motorcycle according to the law, rather than a "moped". In some states, that means inspection, and the helmet thing, as well as a special operator's license. Whizzer did not content themselves with producing engines.
Inthe Pacemaker was introduced with an Automatic Clutch. July 19, The "Sportsman" was introduced with a two- speed Automatic Transmissionwhich up shifted at about 15 mph. The transmission, called the "Bi-Matic", was manufactured by Reef Industries. Unfortunately, the "Bi Matic" proved to be unreliable, and was only sold for a year. The Ambassador above has a "Bi Matic" on it, although it is difficult to see.
Several collectors are running "Bi Matics" which have been re- worked using caged bearings. They have proven quite satisfactory. There is also a "Bi Lite" head and tail light kit for all the bikes. The earlier generators were made by Bendix. Bendix Generators mount on the coil guard, the Halls mount between the exhaust elbow and the cylinder.Though perhaps more "motorbike" than " motorcycle ," Whizzer's contribution to the sport centers more on what it did than what is was. Mounts like the Whizzer Pacemaker gave virtually anyone the chance to experience motorized travel.
Not fast travel, mind you, but faster than their legs alone could take them. Typically affixed to Schwinn bicycles, these kits included a two- horsepower flathead engine and associated drive accessories that allowed speeds over 30 mph.
After World War IIWhizzer produced a vastly more powerful engine -- now a raging three horsepower -- and eventually offered it complete machines. These were Whizzer Pacemakers, which could be fitted with all manner of ritzy accessories, including "dual" exhausts. Many an enthusiast cut their riding teeth on Whizzers in the early s, the experience often encouraging them to progress to larger mounts.
Whether the company's popularity helped incite the scooter trend in the late s is hard to say, but if so, Whizzer became a victim of its own success. With the flood of imported scooters and mopeds that swept the country in the s, Whizzer faced competition it couldn't underprice, and the company closed its doors in Even after the Whizzer Pacemaker motorcycle was introduced, the company continued to sell kits advertised for their ability to convert any "balloon-tire bike" to motorized transportation.
After experiencing a Whizzer, enthusiasts often graduated to larger mounts. See more motorcycle pictures. Whizzer Pacemakers could be fitted with an assortment of accessories including "dual" exhausts. Whizzer's initial cc flathead single-cylinder engine supplied two horsepower ; a later cc version upped that to three. Pacemakers featured a rudimentary telescopic front fork. Accessories for the Pacemaker included a chrome headlight and taillight.
The Pacemaker's chrome fuel tank and speedometer gave the bike a flashy look.

Whizzer U. The Whizzer bicycle engine was first produced in by Breene-Taylor Engineering, a Los Angeles-based manufacturer of airplane parts. Bysales of the engines had not been entirely successful, having sold only about units. ByWorld War II was well underway, and Whizzer Motors were forced to lobby the United States Government for the right to continue production of what was argued to be a great way for defense workers to travel to and from work.
InWhizzer sold its first pre-assembled motorized bicyclethe "Pacemaker". Whizzer motorcycle engines would cease to be produced in due to the increasingly competitive bicycle engine market. InWhizzer motorcycles were brought back into production in the same style of the originals but with technological improvements. However, the Whizzer company as of now appears to be "on a temporary hiatus from bike production" since at least Its website states that there are "still some dealers selling NOS bikes", and also that, "in addition to supporting dealers, Whizzer continues to offer replacement parts, accessories and collectibles for the new generation Whizzers.

How do you start your Whizzer?

American author, inventor and futurist Raymond Kurzweil has become well known for his predictions about artificial intelligence and the human species, mainly concerning the technological singularity. He predicts that Artificial Intelligence would outsmart the human brain in computational capabilities by mid-21st century.
His first book, The Age of Intelligent Machines, published in 1990, put forth his theories on the results of the increasing use of technology and predicted the explosive growth in the internet, among other predictions. Later works, 1999's The Age of Spiritual Machines and 2005's The Singularity is Near outlined other theories including the rise of clouds of nano-robots (nanobots) called foglets and the development of Human Body 2.
Kurzweil's first book, The Age of Intelligent Machines was published in 1990. It forecast the demise of the Soviet Union due to new technologies such as cellular phones and fax machines disempowering authoritarian governments by removing state control over the flow of information.Motorized Bikes VS Mopeds
He also stated that the Internet would explode not only in the number of users but in content as well, eventually granting users access "to international networks of libraries, data bases, and information services". The third and final section of the book is devoted to elucidating the specific course of technological advancements Kurzweil believes the world will experience over the next century.
Titled "To Face the Future", the section is divided into four chapters respectively named "2009", "2019", "2029", and "2099". For every chapter, Kurzweil issues predictions about what life and technology will be like in that year. The device was portable, but not the cheap, pocket-sized device of the prediction. While this book focuses on the future of technology and the human race as The Age of Intelligent Machines and The Age of Spiritual Machines did, Kurzweil makes very few concrete, short-term predictions in The Singularity Is Near, though longer-term visions abound.
Kurzweil predicted that, in 2005, supercomputers with the computational capacities to simulate protein folding will be introduced. In 2010, a supercomputer simulated protein folding for a very small protein at an atomic level over a period of a millisecond. The protein folded and unfolded, with the results closely matching experimental data. Chess Champion and International Grandmaster Larry Christiansen in a four-game match.
Another 3 are partially correct, 2 look like they are about 10 years off, and 1, which was tongue in cheek anyway, was just wrong. Kurzweil said in a 2006 C-SPAN2 interview that "nanotechnology-based" flying cars would be available in 20 years.
Kurzweil believes, by the end of the 2020s, humans will be able to completely replace fossil fuels. In the cover article of the December 2010 issue of IEEE Spectrum, John Rennie criticized Kurzweil's predictions: "On close examination, his clearest and most successful predictions often lack originality or profundity.
And most of his predictions come with so many loopholes that they border on the unfalsifiable.
