BIKES BY WHIZZER
Bikes by Whizzer
Pacemaker; Sportsman; Ambassador
The Whizzer 49 Pacemaker
By June of 1948 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 1000 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 562.)(June, 2001. We just came across number 936. It is definitely a Whizzer frame, and has a Schwinn Springer.) The Pacemaker was offered at least up to 1954. See the article by Leonard Davis
The Whizzer Sportsman
In November 1949 Whizzer introduced a 20 inch model. Too low to have pedals, it was equipped with a kick- starter. This is the "Sportsman"; with the "300S" engine. It was an "in house" produced bike. (There is some documentation that Schwinn built the later frames.)The first "Sportsman" was made by Whizzer Production Manager Don White for his seven year old son to ride.
The Whizzer Ambassador
In 1951 a 24 inch version, called the "Ambassador"; was produced. It was equipped with the "600s" series engine . There were at least 4876 "Sportsman" and 1128 "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.
The Service Pickup"
Both the Sportsman and Ambassador are valuable collector’s items, especially the "Ambassador". 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. In 1948, the Pacemaker was introduced with an Automatic Clutch.
The 1950 "Sportsman" was introduced with a two- speedAutomatic Transmission
There is also a "Bi Lite" head and tail light kit for all the bikes. The earlier generators were made by Bendix.The Bendix Generator The later generators are Hall, beginning in March of 1948. Bendix Generators mount on the coil guard, the Halls mount between the exhaust elbow and the cylinder.The Hall generator
The generators produce about 6 volts AC, depending on speed. When the 300s, 600, and 700 engines came out, the alternator was incorporated into the side cover as part of the cam. There was a regulator built into the original headlight for this series.
The "generators" are all actually alternators, that is: they produce AC not DC Current. That being the case, they cannot be used to charge a battery without a rectifier. Connecting a battery to the alternator will discharge the battery, and may result in the armature af the alternator becoming demagnetized! The voltage produced is very dependant on engine speed and load, and operating at high speed with no regulation or insufficient load will burn out your light.
The "Echo Tube", first introduced on the "Sportsman" has proved to be an attractive addition to other bikes as well. It may take some bending to get it to fit on some bikes.

Messinger made a large saddle
There are fender tips, fender rails, decorations, windshields, and saddle bags.
The head, exhaust manifold, and tall oil breather which appeared on the "300" engine were also sold separately as a "Performance Package". They don’t do much unless you enlarge the valves and the exhaust port on the earlier engines, but they look neat. The tall breather increases the oil capacity in the crankcase to 8 oz., which helps with the lube problem.
There is even a
Weber made a "hot" cam, and high compression head for the Whizzer
Martin made an overhead valve conversion kit.
There was a needle bearing crank made in Germany from 1953 on to replace the standard insert crank. They are a very desireable item, as the crankpin and needles are replaceable. They sometimes have a tendency to be a little noisier than an insert crank.
