The Raleigh 20 folder bike
Does anyone have any experience with vintage folding bicycles? I am intrigued with the Raleigh 20 folders from the late '60s-early 70's. They seem to be great bikes. Are they good for taking in buses, trains, etc? What kind of ride do they have? Thanks!

Good bikes (lots of folks on here have restored and ride them) but they do not fold small enough to take on mass transit, IMO.

Mine ride just like my big Raleigh 3 speeds. I have made modifications to mine, but it still looks pretty much stock. I enjoy riding mine, but if you are looking for light weight or small fold, that is not a Raleigh Twenty.

The Raleigh Twenty has a large and devoted following around the world and was sold under many of Raleigh's sub brands like Phillip's, Triumph, B.S.A., and was even sold as a re-branded bicycle for Canadian Tire stores in Canada.
There are small variations between the brands and they were also produced in New Zealand... these models lack the lower double strut which is not actually needed structurally but does lend a greater appearance of the bike being more solid.
We have 2 Raleigh 20's in original and nearly original condition, one os a British model with 451 wheels and the other is an export model with the more common 406 BMX size. I also have a Phillip's 20 that is one of the most heavily tweaked 20's on this planet and can barely be called a 20 anymore.
The stock 20 weighs 36 pounds and their biggest issue is wheels and braking, especially on the 406 models... long reach alloy calipers and steel rims does not equal good braking and replacing the stock rims with better alloy ones is the best thing you can do for them. The 451 equipped models stop better as despite their steel rims, they have shorter and stiffer steel calipers and with good brake pads they stop reasonably well.
As my 20 can reach 50kmh on the flats and descend at ludicrous speed it warranted better brakes but that required the use of a torch to add v brake bosses... the stock fork can also be refitted with canti / v brake bosses although this comes at a higher cost and warrants a re-paint of the fork.
My P20... this has taken a great deal of work but I work as a mechanic and frame builder so have access to all the tools and parts one would ever want to do such things.
The 20 also benefits from having less rake in the fork to increase trail... I replaced mine with a custom model but the stock fork can also be modified.

Another small and rather inexpensive modification is to hybridize the headset to remove the stock nylon top bushing and fit the bike with a real headset... this allows for smoother steering and no handed riding which is something that is very hard to do on a stock 20.
This is where many of the nutters hang out...

My aunt gave me her old Raleigh 20 shortly before her death. I modified it by converting it to derailleurs gears with new wheels, an aluminum crankset, cantilever brakes, real front drop outs replacing the crimped fork ends, and a real headset instead of the thing with a plastic sleeve on top. It now rides better. I set it up for my wife, but she uses it with her sister when she comes to visit. My wife then rides my homemade folding bike, also with 20” 406 wheels. The Raleigh still needs a paint job.

Vintage folders! Where?

My Raleigh Twenty is also modded. Cane Creek Thudbuster seatpost, Sturmy Archer XRF-8-W hub, Origin8 crankset, Phil Wood rings with the UN-72, Sun Rhyno Lites, Maraton racers etc. Its a game we play on the internet. Try to stay away from those U frame folders they ride like wet noodles.

One of the coolest things about riding a folder of any kind is the responses you get from people who think that they are; slow, only suitable for sidewalks, twitchy, incapable of handling any distances, or rough riding.
My P20 is fast, smooth, and I have built it up to use as a separable touring bike... it took me 5000 km last year and has seen further modifications.
Quite a few of my friends have folders and have taken my P20 out for a spin and come back saying that it is as stable a bike they have ever ridden and really bleeping fast.
I have yet to restore the fenders and build new racks and even with that extra weight and my touring kit the little bike just buzzes down the road at good speed.

Well, I purchased one the other day on ebay, and it is the maroon-type color. Seems to be 100% stock at the present time. I hope it will be here within a week or so. Does the stock seat post extend well enough for someone around 5'11"?

If you live in the UK or are exceptionally lucky, you might also see the Dawes Kingpin for sale. The two bikes are very similar, the Dawes is made with narrower tubing and I am told has a slightly more sporty ride. The big benefit of the Dawes is that it uses standard threading so a modern sealed bottom bracket can be easily inserted.

The stock 20 looks neat in vintage state. When I get it in, I will head over to the bike shop to see what kind of maintenance/"tuning up" is needed. They'll probably have to work on cables and the 3-speed setup to make sure it is working well, I suppose. It will be interesting to see what kind of ride it is.

In PDX now and riding the '74 which has new rims , new levers, and better brake pads... forecast is for sun but it handles the rain quite well too with these upgrades.
One other thing... the stock gearing is really quite high and a 15 tooth rear cog is pretty typical. Swapping this to take a littl off the top and improve the low end makes a big difference and the 20 here has a 19 tooth rear cog to make climbing long hills easier.

I have a whole section on my Website devoted to restoring my own Raleigh Twenty last year. Click on the "Restoration Of My "New" Raleigh Twenty" link on the left menu when you land on my home page. I have all my photos and chronicled the whole process there.

had to swap cogs on all my Twenties they're just geared too high for those big fat wheels

hope we could ride ciclavia on the Twenty again coming up in October
