New old 3-speed: Dahon Classic III

1988 Dahon Classic III
Meet a Dahon Classic III folding bike, fresh from Craigslist. I always like making bike finds of this sort; virtually unused time capsules that have spent decades in storage out of the elements. This bike could not have been ridden more than a couple of miles since new, some 28 years ago. It had a film of grease and dust, incidentally protecting the finish, as well as mostly dry bearing assemblies. A bit of time with some rags brought back its gleam, and a date with some tools and a tube of grease will take care of the bearings. It has a pristine Sturmey-Archer 3-speed AW hub, date stamped 87-8, for August of 1987.  I'll get to know the hub much better, as I rebuild it to ensure it is functioning optimally after a long period of disuse. Best of all, in short order there will be one more vintage 3-speed back on the road.

This bike isn't mine, as I found it for my mom who plans to bring it with her in a mini RV for wide ranging travels in the near future. However, I was surprised that at my height of about 74 inches, I could extend the saddle and handlebar enough to ride it comfortably. So could Big Sis, who at a foot and a half shorter than me, was an eager test rider.

I'm somewhat familiar with newer folding bikes, but was surprised at the quality of build and engineering incorporated in this bike, a design that originated nearly 40 years ago. Newer versions are lighter, faster to fold, and offer more features, but Dr. David Hon really nailed it when he envisioned this catalyst for intermodal transportation. If you're in the market for a folding bike and don't want to spend a lot of money, you can't do much better than an older Dahon like this, provided it's in good condition.

Below are some photos of the bike to dwell in the cloud in perpetuity for anyone searching out details of a vintage Dahon Classic III.

Ready to ride...
...and folded, for comparison.
Sturmey-Archer shifter in great shape.
Note the asymmetric design of the handlepost brace.
The Lee-Chi caliper brakes on chrome steel rims function remarkably well. 
Folding crank arm on the drive side. 
The head tube is just a squat cylinder. Wheels are 16-inch. Everything is stock original.
Serial number stamped on the top of the bottom bracket shell. Directions on how to interpret the date codes are here.
Shiny Sturmey-Archer AW 3-speed hub.
A little caster wheel folds down so that the bike can be rolled when folded.
Bottom of the headpost assembly, with a hinge that folds to the left side of the bike.
An astonishingly narrow front hub. I haven't yet measured it, but I've never seen one so narrow. 
Badge above the reflector on the rear fender.
Right side of the bike, when folded. Note the caster wheel.

View as folded from the rear, or front, depending on your philosophy.

Approximately 56" tall rider.

Familia de tres Xtracycles

Left to right: Xtracycle Schwinn Panther (big sis), Xtracycle Breezer Villager (mom), and Surly Big Dummy (dad and lil' sis)
After an Xtracycle on long term loan was recently returned, we now have three longtail cargo bikes in the bike barn. During the time the loaned Xtracycle was absent, big sister grew enough to be able to ride it. Since about the age of three, when she first started riding as co-pilot on the Big Dummy, she's been talking about having a longtail of her own. Now she does. There are not likely too many 10 year-olds in command of a cargo bike, so it will be interesting to see what sort of adventures it inspires.


In other news, little sister is on the brink of moving up from 12" wheels to 16" wheels. Out of storage comes our 16 inch-wheeled Schwinn Trixie, an old friend that has seen a string of riders in our family. This venerable steed is a great introductory dirt bike for our local suburban singletrack, and has logged hundreds of miles and scorched thousands of skid marks. With a little tune up, it'll be ready for many more.

Long time, no see

It would be reasonable to have given this blog up for dead. In fact, it may yet be. For a long while, I've had nothing much to add to the ever expanding universe of online activity flowing though myriad venues under a plethora of contrived names. However, I may yet post something here from time to time. Even in my negligence, this site has somehow logged nearly 200,000 visits since it began.

In any case, happy 2016. I hope to spend as much of this new year on two wheels as I am able.

First day of school, 5th grade edition

For each first day of school starting with kindergarten, we've ridden to school. This final year of elementary school was no different.

Bewilderingly, the first day of school is a half day on a Friday, effectively stealing the last weekend of summer vacation. I can't imagine that much will be learned, yet this is the second year in a row that this has been the case, so it's apparently not a fluke.

Also bewildering, was when we arrived to discover new picnic tables installed close to the bike rack. The tables greatly impede access to the already lousy wheelbender bike rack, rendering the rack nearly useless. This is a textbook example of designing to fail. It may be no coincidence that we were the only ones who rode to school today.

Bike camp & birthday wheels

Flying on her new Specialized Myka. 
Though already half over, July has been eventful, encapsulating bike camp in Waterton Canyon and a double digit birthday. For good or bad, bike camp happened during an especially rainy week in an abnormally rainy year, so big sister is now a seasoned veteran mud rider.

In the midst of bike camp, she made the jump from 24-inch to 26-inch wheels, via a slightly early birthday bike. The 13-inch frame of a 2012 Specialized Myka Sport is the perfect entry to the world of high quality, big people mountain bike parts. After I performed a quick rebuild, the Myka now features a 2x9 Deore drivetrain, Avid BB5 disc brakes, wide 26" tires, and a Rockshox Recon Gold 100mm suspension fork.
The girls each on new-to-them bikes. 
I decided after she toughed out the first few rain soaked days of bike camp without complaint, that she was due for the bigger bike. Her old bike, a Specialized Hotrock 24" has served us well, but its gearing was not ideal for conditions, and had begun to look a bit small in proportion to her rapidly growing limbs.


Soaked but smiling after the first epic ride of camp. 

She was particularly proud of how muddy her legs were. 

I sewed a tiny framepack to help with the load. 

The Myka will need a larger framepack. 

Friend to amphibians. 



Skipping rocks is an important skill to master. 

The Cateye logged 56 miles of trail over five days. She said she could have gone a lot farther. 

After she figured out that the bigger bike could do things that her old bike couldn't, it was an instant hit. It didn't hurt its popularity that Lael also rides a black Specialized bike. She was especially amazed at the ability of the Rockshox Recon to both smoothe the trail and improve control in a way the mostly ornamental RST fork on her Hotrock simply can't do. In all, she's faster and more confident on the Myka, though there is still much to learn.



Packing material shenanigans.
