A Guide to the Schwinn New World Bicycle


 The Schwinn New World was Schwinn's attempt to make a lightweight, roadster type bicycle similar to Raleigh's Sports. It was produced from 1938 through the early 1950s. The World Traveler model succeeded the New World in the early 1950s and looks similar.


The catalogs switch from "New World" to "World" and "World Traveler" in 1950, though it is possible there were some New World leftovers in 1950. The "World" and "World Traveler" bicycles were initially quite similar to the last New Worlds.





Schwinn believed the time was right in the late 1930s for American teenagers and adults to take up cycling as recreation and exercise. Frank Schwinn in particular believed that lightweight bicycles like the New World, Superior, and Paramount could do for adult cycling what his balloon tire cruisers had done for adolescents, namely revive a slumped market.

While Schwinn's concept did not pan out in terms of adult cycling in America, the idea gave rise to some of the best riding, best-built bicycles of their day. They continue to make excellent riders and are very attractive machines as well.

So, let's take a look at a few features of the Schwinn New World roadster, Schwinn's attempt to bring light duty cycling to American adults in the 1930s, 40s, and 50s.

The guide deals with New World "tourist" or roadster type bikes. There was also a line of New World "racer" type track bikes, but they are not addressed here.


I. Frame Sizes


First, Schwinn New World roadsters of the 1940s-50s  tend to have a longer wheelbase and more relaxed frame angles than the Raleigh. They generally appear in 19 and 21 inch frames.



Remember, your saddle may be able to slide forward and backward on its rails to help you set up your fit. You can also flip the seat clamp around. To confuse matters even more,

New Worlds also tend to have shorter frames in terms of height. Raleigh's Sports generally was a 21 inch or 23 inch frame. Schwinn's New World ran 19 and 21 usually, though 23 inch frames exist, according to the literature.  The trick is to look at the head tube spacing between the top tube and the down tube. If the bars meet at the head tube very close, 19 inch. If moderately spaced, 21 inch. If they are quite far apart, 23 inch (uncommon).



I've seen only one 23 inch frame from the 1940s-early 50s era in a Schwinn, and it was an early 1950s World Traveler (a close descendent of the New World). The black bicycle to the left is 21 inches. 23 inch frames exist, but are uncommon. Some New Worlds also came with locking forks.








Kickstands: it is also notable that pre-war New Worlds generally have separate, Miller-made kickstands. Post war would be the kickstands built into the frame.

Ladies: prewar ladies bikes usually have parallel tubes with a cross member between them. Post war usually has non-parallel tubes without a cross member.

Handlebars: the bike above has the "flat" tourist type bars, though some New Worlds came stock with ballooner/cruiser "scout" type bars with more rise and pullback to them. Stems could be goose neck or "double adjustable type".

II. Construction


Schwinn New Worlds are also fillet brazed bicycles rather than lugged (see Sheldon Brown's site for a definition). Early New Worlds were made of seamless tubing, a nice plus. Later Schwinn roadsters are generally Electroforged, whereas earlier models from the 30s- late 40s are fillet brazed. The pre-World War II New Worlds are fillet brazed. Schwinn switched to part electroforged and part fillet brazed frames after the war.





III. Cranks and Transmissions


Schwinns come available with a very wide variety of American and Euro touches. Some have inch pitch one piece cranks, others have three piece ones that are cottered. Some Schwinns were single speed coaster brake models, others were 3-speed Sturmey Archer types. Still others used a single speed freewheel.







The crank to the right is a 1941 3-piece Schwinn crank. The black New World above is a 1-piece ballooner type with inch pitch.  You find these with the single speed freewheel and the coaster brake models.












A single speed freewheel using the Paramount high flange hub could also be bought. Interestingly, this type of wheel can be found with both the inch pitch and the standard pitch models. Sprockets thread onto the hub. There was also a low flange single speed freewheel made of aluminum called the "Dural" hub. The catalogs list Schwinn drum "pork top" brake hubs as an option as well.








Stock:
a. Coasters: either standard pitch or inch
b. Paramount/freewheel single speed: either type also
c. Sturmey Archer 3 speed AW: standard pitch
d. Low flange "Dural" aluminum hub single speed freewheel (catalog shows standard pitch)
e. Schwinn "pork chop" drum hubs (catalog shows standard pitch)

Variation:
I've found that if you use an Ichibike type "conversion" cog, you can run inch pitch on a Sturmey Archer 3 speed hub. I use that on my 1947. This is not stock, but allows you to run a vintage, 3 speed transmission with your skip tooth set up.



IV. Saddles

The stock New World saddle was often the Mesinger tourist type. But some used Mesinger ballooner saddles. Both types were able to slide forward and backward in sleeve-type clamp. The saddle below is the sliding, Mesinger tourist type. Note- it has rear coils like a Brooks B66, but a front loop spring as many ballooner saddles do.




This green, 1941 New World uses a ballooner type saddle with a funnel springs. This is correct for the bike- it is the Mesinger funnel spring, sliding saddle.

 
Schwinn uses the American "cruiser" saddle type seat posts. I have converted my 1947 to a Wald post to use a nice Brooks B66 roaster saddle. This approach blends English and American styles and makes for an outstanding ride. The saddle at left is certainly not original, but allows you to ride in vintage style, comfortably, and without wear to an original. The seat post is a basic, new Wald.












 VI. Brakes


Schwinns could come with caliper/hand brakes, or coaster brakes.  Earlier Schwinns have "Schwinn Built" calipers made in the USA. They use a standard cable.












 It was not uncommon for Schwinn to use coaster brakes from their ballooner line as well.Some even had a hand brake on the front and a coaster on the bake.












Note on handgrips: most postwar models had Schwinn script grips with finger ridges. Older bicycles had "ball end" ballooner type grips. At what point the change was made, I do not know. But you can find both and either could be correct. Catalogs show 1941 models with ball end or "ringed leader" model grips and 1945-46 models with script grips in the pictures, but list "Schwinn cushion" grips as an option. It could be 1941 was transitional in having both as options. It appears American-type ballooner grips of one sort or another were always used, not English type grips as you would see on a Raleigh or Hercules.

VII. Wheel/Tire Sizes


Early (pre-war) New Worlds use the old US lightweight (ISO 599 size) tires. They are very difficult to find today. Later ones from after WWII switched to Schwinn ISO 597 (S5 and S6) tires. You can still get these new, but the selection is limited. I run black Kenda tires on my 1947. The rim at right is an ISO 597 (1947) Schwinn "straight sided tourist" type. They use the same tires as S5 and S6 rims. By the late 1940s, catalogs specified the S6 (box pattern) as the New World rim.







The 1941 New World at left uses box-pattern, old type US lightweight rims. My suggestion with these is to swap in a later Schwinn wheelset using the 597mm size. On my 1947, I swapped in a later set of wheels that use S5 rims. Getting tires for the prewar lightweight 599mm size is a real pain.









VIII. Paint Detailing

Schwinns came in a variety of colors. Black and maroon are most common. Other colors were made though. They generally used "box" type pin striping. Some black Schwinns before WWII had green and red box striping, while most others had gold. Today, the gold has faded on most bikes to a tan/brown color.







 The 1941 Schwinn at left is a nice, dark green color. It is a less common color than maroon or black.Colors include black, maroon, white, dark green, blue.







IX. Braces and Clamps

Pre-war and the earliest post-war Schwinns had seat clamps that were integral to the seat post. On those bikes the fender braces were also wire. The rear braces connected to the axle.










On later bikes, the braces were larger and shaped more like the ballooner braces. The rear braces went to a dedicated hole on the back of the dropout.












These bikes also had a grey, separate clamp that went over the seat post. They often have "AS" stamped bolts. The postwar New World at right shows the removal of the separate clamp. The seat post is a plain tube with a slot cut in it. The separate clamp goes over the plain tube. A prewar bicycle (or the earliest 1946 bikes) would have the clamp integral to that tube and painted the same color as the rest of the frame.









X. Chain Guards and Fenders

New Worlds usually have "blade" front fenders and plain, round backs. Some may have used the Superior type "low profile fenders" but those are the exception.












Some New Worlds came with the 1930s type "plain" Schwinn guard, while some later New Worlds had more ornate, wing-type guards.  Bikes made in 1941-42 and 46 may have "black" out parts mixed in, meaning certain chrome parts were painted black because chrome plating involved strategic war materiel.















The catalogs state that these bicycles could be built up with "any combination" of English or American components, which certainly seems to be the case. The result is that you have a bicycle "platform" that may appear with a wide variety of components. Telling whether the bike is original is tricky, so the best thing is to keep an eye on the age of the components in use. If they appear within the pool of "possible" items and are from the correct era, you are on the right track. It's always possible you have period correct modifications to the bike, but don't give up on a bike just because it has an odd assortment of parts within the pool of possibilities.

I tend to think of the New World tourist as more a "platform" than an individual bicycle. Such a wide variety of parts could be used that the model is best thought of as a "core" with dozens different combinations of parts possible.

  1. I am interested in selling a 1940-1941 Men's Schwinn New World Sports-Tourist. This was my Mom's bike; she purchased it from a friend just before he headed off to war. It appears to be pretty much original, except for the tires and an added kickstand. Any suggestions on where to sell such a bike?

  2. Would try www.thecabe.com or, if you know how eBay works, maybe eBay. Craigslist is an option, but it draws a lot of spammers. I prefer the CABE between those. You may end up having to box and ship the bike if you sell online. Local online sales are notorious for lower prices. Do you have any pictures of the bike?

    1. I sent an email yesterday, but I think it bounced - didn't notice that your email was a "no-reply". Anyway, thanks for the info - I will try CABE and eBay. I do have a number of pics of the bike-let me know how to get them to you.
