Hello & Welcome to my "Raleigh Twenty Project!

In late August of 2007, my annual vacation period was fast approaching, and I wanted (actually needed) a fun project to keep me busy during my vacation period.

After a time of consideration (a very small bit of time you understand), I decided to strike up a new bike build project, so thought more about it for a few days considering what type\style of bike I wanted to build.

Initially, I thought of building up a "Mixte" bike frame. I like these frames, and thought that it might be a fun project to embark upon. So, I set out to see if I could find a nice Mixte frame, in reasonable condition, and the same in price.

I began my search by reviewing the bike ads on our local "CraigsList" site and waded through the various bikes listed. I found what sounded like a nice Mixte ad, but the woman selling it would not commit to a target price range. In addition, she lived about an hours drive from Victoria. I didn't want to waste my time and gas to drive there and have her change her mind a few times on the price (which is what she was doing during our phone conversation) and end up driving away empty handed. Very odd person she was...

Anyway, continuing the search, I happened upon an ad for a Raleigh folding bike. The picture of it captured my imagination, so I decided to Google the "Raleigh Folder" and happened upon several very interesting rebuilds of this intriguing "little bike".

I spent a few hours studying those sites, and decided that this would be a very fun build, and probably a fun bike to ride. I ended up purchasing the advertised Raleigh Twenty, and the following is my accounting of the project.

If you are an R-20 enthusiast, I hope you find this accounting of interest. If you have the same interests about modifying or customizing a Raleigh Twenty, then I hope that the following may provide some helpful tips and ideas, and may inspire you to do a similar build.

If you are simply a bicycle enthusiast, I hope this page provides you with some interesting thoughts of how I took this old tired bike, and gave it new life by providing it with "an injection of youth" from a series of new modern parts, and several frame mods as described below.

If you have any questions or comments, please feel free to .

Here is the Raleigh Twenty Folder I purchased from a seller on Victoria's Craigslist. It cost a whopping $150.00, but it is a good strong frame. It was worth the purchase in order to begin my September project. Though not much to look at presently, I trust it will end up becoming a very nice and interesting little ride.

Using another R-20 to mock up a few parts while the main subject of this build is away having more complex work done to the frame, the pix below provides some views of the way the cockpit, the rear rack and the water bottles will be set up.

Studying the profile of the mocked up R-20, I wondered how much of a difference in sizing this bike will be from my 54cm Surly Long Haul Trucker touring bike.

Measurements were recorded of a few areas of the two bikes to compare the differences. The results are as in the following chart...

Area Measured Surly LHT Raleigh 20
Handle bar height
(floor to centre of h/bar tube)
38.25in/97.16cm 38.25in/97.16cm
Seat post height
(floor to top of bottom plate)
33.725in/85.66cm 34.375in/87.32cm
Stem to Seat nose
18.75in/47.63cm 18.50in/46.99cm
BB to Seat post height
(top of BB to top of bottom plate)
23in/58.42cm 25.125in/63.82cm
Wheel Base
(axle centre to centre)
42in/106.68cm 37.75/95.89cm

Today, I picked up the modified frame from Max at Fairfield Bike Shop. Before I take it into the powder coaters, I thought I would take a few pix of the frame mods done by Max. They may not look pretty at this stage of the build directly after the brazing, but I thought this might be a good time to take a few pix to display the mod made to the frame. This afternoon, I will be dropping the frame off to Victoria Powder Coating for finishing and colour application.



  08 December 2007

I picked up the R20 from Fairfield Bikes today. It is pretty much complete now. I may make a couple of changes yet, but, as I say, it is pretty much done. I am so pleased with the finished product. It turned out so much better than I had hoped for. The colour looks so nice; the parts seem to work together so nicely. It's a WONDERFUL ride! Below are some pix of the completed bike. More pix will be added shortly to provide a better idea of how it looks when outside, and to provide some other profiles. If you have any comments on the build, please .

When in Victoria, visit...
In Victoria its Fairfield Bicycle Shop for your cycling needs!
...for all your cycling needs.

I did not do the work on this project on my own. Far from it.

Note that the greatest majority of the work done on this project was performed at what I consider to be the finest bicycle shop in Greater Victoria BC Canada. That being the shop noted above: Fairfield Bicycle Shop. In particular, my thanks goes out to Max, a master mechanic at this shop, who performed the frame mods, the initial parts set up, and the fine tuning that was involved.

In addition, my thanks goes out to all the other experienced and knowledgeable employees at this fine shop who put up with my frequent visits, and who answered all of my seemingly endless questions.
