While we've lost count of the classic
bikes we've repaired and restored here at the shop, our sense of
wonder at the unusual and beautiful products of the last century is
far from dead. When this 1959 Apollo rolled through the door, we
realized early on that under all the surface corrosion and cracking
rubber we'd find a gem. Some might call it an antique, but this
classy old roadster has a new lease on life and a new chance to get
out there onto the pavement. We had a great time working on it, and
thought we'd share a little!
A shot of the bike before any work was done.
Steel wool, if you didn't know, is excellent at removing corrosion from chrome.
Left = pre-polishing, right = post-polishing. So shiny!
The finished product.
Check out those sweet rod-actuated stirrup brakes.
They really don't make them like they used to.
Time and leather treatment and more time.
Shiny means smooth braking.
So clean you can see me in it!
I’ll admit it.I’m a little jealous that Seattle gets a Snowpocalypse before Chicago does.I take pride in my city’s brutal winters.So now that Seattle has had its fun it’s finally Chicago’s turn to play in the snow.And while Fritz may happily snip zip ties off his bike now that things are back to normal over there I’ve got three inches of snow on the ground and more on the way.In a matter of days the plows will shove all the snow in the valuable lanes of pavement I like to ride in, and soon after that all that snow will be compacted into something far more slippery than snow.So, sure, Seattle gets “battered” once or twice every year, but what about real winter?
What about many sub zero days, lots of scorching cold winds, the possibility of frost bite, snow, ice, more snow, more ice, and the inevitable lake effect misery that is the reality for all us crazy Midwestern winter riders?What good is a bike commute if every time I swerve to avoid a collapsed catch basin or perilous pot hole, I lose traction and end up a pile of painful person underneath my bike?Anyone who has attempted to ride down the lakeshore path will know what it’s like to see the sheen of a vast expanse of ice ahead.When I was younger and I rode my 1977 Trek TX550 through such conditions, I just barreled through and braced for what I knew was going to be a couple of very uncomfortable moments.But that was back when I trusted my patellae wouldn’t shatter upon impact, before I had any sort of thoughts that some injuries are more than just annoying to walk away from and some pain is too great to ignore.
Anyway, what do we do about the dangers of an entire winter of ice and snow?
The Answer is studded tires.
These are the Schwalbe Marathon Winters I like to use.(and that’s Chris in the background)
These things are great.Greater, I might argue, than the zip tie snow chains.And I might argue this because, well, I’m a bit too classy to be uglifying my stately Dutch bike with silly little zip ties.(Kudos to you, Fritz, for choosing such a bright and safe color for your snow chains.Safety first!) Seriously though, if you plan on riding through an entire winter, the studs will save you just when you need saving.
Remember when Fritz boasted of his uncanny placement of the zip ties so that they bit into the ice while cornering?That’s the whole idea behind the placement of the carbide studs in the Schwalbe Marathon Winters.The studs are arranged so that when running at full pressure your tires will primarily be making contact with the road right in the middle, on the rubber.When you start cornering, the studs will do their job.Of course, when the roads do get totally nasty, and the ice and hard pack snow is everywhere, you might just want to lower the pressure and let the carbide studs do their thing all the time.With the increases contact area of a soft tire, the studs give you way more traction.
With 240 metal studs on 700cc tire I feel secure on my ride no matter what I roll over, I’ll keep my wheels underneath me. They also have the Schwalbe standard reflective strip on the side wall which makes me feel not only bijster (very) European but also bijster visible.
It’s true. You will sound like a swarm of bees when pedaling along dry clean pavement. But the advantage when you need it is well worth the noise. And when you arrive to work, or the bar, or back home again all in one piece, everyone will be very happy to see you.
We’ve got the tires in stock now, and we’ll get just about any size you need. Heck, I’ll even put them on free of charge. That’s how much I care about your safety.
Glad you finally got around to getting those tires on Vince! We don't want you to fall and get hurt. Nice close-up picture of the carbide studs by the way.
No matter how much we swear we've
learned our lessons, Seattle always seems to get caught by surprise
by the snow. There we were, minding our own business with our feet
all toasty in our sandals and socks, when the temperature plummeted
and it turned into Juneau in January. While this year the City did a
much better job than last year at preventing widespread carnage and
destruction, we at Dutch Bike Seattle still didn't bring in studded
tires because it never snows in Seattle. Even if we had stocked
them, I'm not sure they'd sell because it never snows in Seattle,
right?
We found something else, though.
Something else entirely.
You're not going to believe it at
first.
It's quick, it's cheap, and yes, it
looks completely ludicrous.
BUT. It works. It works beautifully.
I can accelerate, brake, and corner
with aplomb, even on the vile snowpack/sheet ice mix the plows leave
in the bike lanes. The zip ties dig nicely into the hardest packed
surfaces, but they're thin enough not to bounce the bike around at
low speed or on short pavement sections.
I've cunningly positioned the tie heads
to dig in as soon as the bike goes into a corner while staying up and
off the ground in a straight line. This is the place that the ties
are most likely to interfere with the fenders, so if you're
installing these yourself be careful to make sure you have or can
create the clearance.
It is at this point that I must admit
that I didn't dream up this amazing technique. It pains me to admit
this not because my ego suffers, but because the
zip-tie-DIY-bicycle-snow-chains idea appears to have originated with
my favorite bicycle industry whipping boy: fixed gear hipster
culture. Several years ago, I'm sure, some bright child with
extremely tight pants and an asymmetrical haircut had a
genius-caliber idea, and I hate that it wasn't me. So here it is:
Fixed gear street bike hipster guys, I'm sorry for the things I've
said over the years. It's not true that the only drink you like is
4Loko. It's also not true that you're not allowed to wear shoes that
don't match your bikes. You can wear whatever you want. And
finally, you have come up
with a good idea besides brightly colored deep-section rims.
I believe there are two problems with this: punctures are a complete nightmare and the zipties aren't durable enough if you encounter ice-free asphalt on main roads. We make our own from old MTB knobblies and the shortest woodscrews we can find, inserted through the knobs inside-out. You need many layers of Duck Tape or a tyre liner to avoid the screw heads pinching the tube.
Hey Im going to try this next time we ride the Shore in the snow might help.
blmuzzy commented on 30-Nov-2010 06:43 PM
The author also appears to have adopted the #1 worthless affectation of hipsters - top tube pads. Although a real hipster wouldn't have disc brakes OR rim brakes. How ironic...
My goodness, yes! A flat while set up like this would be time-consuming to say the least. This emergency measure will certainly not work for every bike, either. We'll address a more professional, longer-term solution in a few days, never fear!
Oh, and for _genuine_ irony, you need look no further than the skinniness of my jeans.
Keep cycling sexy!

It's also the budget studded tire solution for cyclocross:
This meant that essentially all actions resulted in automated winding. The 1st man to utilize the automated idea towards the wristwatch was obviously a guy through the identify of John Harwood. Harwood took out patents involving mechanisms that grew to become identified as "hammers" or "bumpers." While this system only wound the timepiece when it absolutely was moved in a single direction, it do let for twelve working hours of autonomous timepiece performance when it http://www.thomassabomarkt.com/ absolutely was entirely wound. This timepiece was developed in the great deal of 30000, and was the 1st commercially profitable automated watch.
You know, I'm going to leave that up. I think it's the best spam I've ever seen. I wish I could come up with verbiage like "obviously a guy through the identify of John Harwood." I bet that was painstakingly translated from the Queen's English into Bahasa or Hindi by someone that was deeply obsessed by the history of mechanical timepieces, and then brutally babelfished back into a semblance of 'Murrican by some crazed robot spider. Thank you, the internets, for reviving my sense of linguistic wonder.
Here in Sarasota, FL, we don't get any snow, but I wonder how well this technique would work for a roadbike on the beach? I get no traction with my bike now in the beach.
The "snow bike" is my Saison, a bike we assemble on a Surly 1x1 frame. You can see more detail on the bike and the parts spec in my post "A Year of Saison," from sometime last summer. It's a blast to ride, and makes for a great around-town rocket. Most importantly, though, the irony radiating from my top tube pad makes me 15% more efficient and keeps my knees warm!
So awesome, I wanted to do my own test. You can find it at wijfietsen DOT nl (sorry, this commentbox doesnt seem to approve URLs). You might want some help from google translate (it's in Dutch) but the result was disappointing: my rim brakes turned out to be the spoilers. Too bad!

Does it also work for cars?
Merijn Vogel commented on 21-Dec-2010 10:34 AM
Bart: act first think later, good motto :-)
Haven't cycled since beginning of snow, a recumbent is a bit more prone to falling than a regular mountainbike (but with the big advantage of being close to the ground you won't fall as dangerously on a recumbent). Also, the pickle (if that't the English word) to de-ice the roads damage the chain and derailleur too much in my opnion.
Sjefke commented on 21-Dec-2010 11:57 AM
@Reinier: YES! It is called snow chains!
An other option is to get a serie of small metal plates, bend the edges and tooth them. Distribute evenly over the tyre and connect to two steel cables that go alomg the side of the rim. It is a Canadian solution to create snow chains for bikes.
Ken commented on 22-Dec-2010 09:53 AM
This is pretty cool! I love zip ties. Countless uses. I use them to hold down one of the wheel covers on my car because the clips broke. It doesn't snow much where I live in the southeast, but one day it did, plus ice. I decided to ride my mountain bike to work. I fell about 3 times along the way because I failed to predict the physics of trying to ride two wheels on something very slippery. Never again.
We've got a lot of snow lately here in the Netherlands. Maybe I'll give it a try on my bike. A bike is still way faster here in the cities than a car because of the traffic jams and lights.
marcus commented on 23-Dec-2010 11:43 AM
I tried it today, but the zip tys break because they are cold. Still on the moment I'm installing them. I bought two types of zip tys but both are of this bad quality. Any tips on wich zip tys to buy?
@marcus: I had a some breakage when I zipped a few ties too tightly. The tire (or rather your weight upon it) generates a huge amount of outward force when it expands at the contact patch, and if the ties are too tight the tongues will blow out. If they're actually becoming brittle with the cold, it must be possible to find some designed for low-temperature use. That said, at a certain point it might become more sensible to spring for studded tires. I love rallying bakfietsen around on those.
Marcus commented on 23-Dec-2010 02:22 PM
I have bakfiets from the Dutch brand Azor, model heavy duty :). Some one gave me a tip this evening where to buy them. They have a metal thingie in the head of the zip tys. If you send me an a-email Ill send you a picture when i`m done.
Tried it, didn't work unfortunately. At least this particular brand of ziptie. I lost half a dozen on a 1km test drive. Well, maybe the other stay on or some other brand would be better.
Jolanda commented on 30-Dec-2010 04:35 AM
This is great! Forwarded it to my son to try it with his wheelchair or handbike. The poor guy had to stay in al week last week because could not get through the snow by himself... so who knows, this tip could help all wheelies to go out!
Anonymous commented on 30-Dec-2010 05:17 PM
I tried this a few years ago, but the zip ties wouldn't last long enough for the long Montana winters, I used a braided steel cable and wrapped it around my front tire, using the zip ties to feep the cable in place Montanahttp://www.facebook.com/photo.php?pid=149456&id=1418636347
This simply does not work, the added traction is marginal, and when i did this a few years ago most of the zip ties wore off by the time i rode the 10k to school. it works okay in deep snow, but is not nearly worth the time or effort. just buy some narrow cyclocorss tires
Back in the late '60s, when delivering newspapers in the winter, we would do something similar with thick twine. Twist-ties had not yet been invented. The idea is very old.
bmx rider from australia commented on 20-Feb-2011 02:10 AM
kinda ok idea if u came up with it when u were stoned..
what may i ask will you do when u get a flat tyre.. cut all the zip ties off.. then have to put a whole new set on..
just get some tyres with tread..durr..

I love cycling in the snow, but I've never found grip to be any problem at all on my mountain bike. On my road bike, the thin tyres will cut into soft snow and it is not so effective. However the problem I have experienced is due to the rock salt that
is put down on the roads when the weather is freezing. This stuff is terribly caustic, and will eat away your chain rings in no time. So if you're going out in the snow, cable-ties or not, be sure to put plenty of protective lubricant on your chain every day.
Yes, I will copy that brilliant idea this winter and quit the snow tyre pages but I'm desperately looking out for 2nd hand saloupettes after last year my legs went numb cycling half an hour despite layering.
JP commented on 17-Jan-2012 03:27 PM
Are you sure it came from hipsters instead of cyclocross? Never done this for snow traction, but have used half a dozen zip ties to keep a back tire on after a long sidewall gash -- enough zip ties to make up for the missing sidewall strength, a little
bit of a bump but a lot better than walking six miles home. You can also DIY winter traction using heavy cord or light rope -- braided polypropylene (an old water ski tow rope) worked well for me, spiral wind through the spokes and around the tire.
Anonymous commented on 19-Jan-2012 06:39 PM
Third hand tool works great to tension the zip ties.
Fall is here!Which means, for those of us living here in Seattle, rain.A lot of rain.Driving rain.Endless driving rain.I’m pretty sure that last November it actually rained every day.However, any experienced Northwestern cyclist can tell you that the best way to combat the crushing depression of the winter months (other than maybe buying a SAD lamp) is to keep riding your bike!And what this means, is fenders.
There are many different types of fenders. Because I insist on riding completely impractical bikes, my only option are the clip on, or “fairly ineffective,” type of fenders.
These fenders are convenient because they simply clip on to the seat stays and fork blades of the bike, and don't need any eyelets or mounting hardware.They’re inconvenient because they don’t really work very well, and as a result my bike is always dirty
and my feet are always wet and sad.
So, despite the more involved mounting process, full fenders are a better option.They provide much greater coverage, which is great for your bike because it keeps it clean, prolonging the life of your components, and great for you because it keeps you more dry, prolonging the life of your ride.A great example of full fenders are the ones that Fritz has on his bike.Look at that clean bike!
And look at those happy feet!
“But wait!” you might say. “I ride a racy road bike! I don’t have room for fenders! Or eyelets!”Not to worry!Both Fritz and myself have extensive experience putting together custom fenders to fit on even the most race-oriented carbon fiber speed machine.There are several ways we can do this, but our most common method is to actually fabricate some mounts out of rack struts (thin, rectangular pieces of steel) and use these to clear the tight spaces in between the tires and brake calipers. In the case of bikes without eyelets, we can use different types of clamps to keep the fender stays attached to the frame.
So why wait! Get some fenders! Keep your feet dry!
We've carried bikes from Linus for more
than six months now, and in that time we've sent a surprising number
of the little guys and gals out into the world in both Chicago and Seattle. It's been a pleasure
to see them locked to bike racks downtown in the Loop , rolling down the Burke
Gilman, and hanging from the chain link outside bars on Capitol Hill in Seattle.
I've seen them used for commuters, bar bikes, kid haulers, and
“couples' cycling incentives.” Just as Linus riders seem to have
discovered the versatility of the design, we've had a great time
expanding the capabilities of the bikes themselves. Here are a pair
of the projects Alex and I have set up with some of the bikes. We've
had a huge amount of fun thinking up ways to keep the Linus style
undiluted while adding function and some new ways to ride! If you cold winter riders are looking to set up your Linus, Chicago Schwinn or Raleigh with a similar light set-up ask us about the Schwalbe studded tires for winter riding.
Classic headlight, classic tire
generator, classic Roadster 3, and a nice warm yellow halogen beam.
Live on the top of a monster hill? The
SRAM i-Motion 9 hub nearly triples the gear range of this Dutchi.
@Roegr: The SRAM i-Motion hubs are not automatic shifting, if that's indeed what you're wondering. When you _are_ the engine, it's pretty nice to have control over your RPM. Cheers!
Just thought everyone might like to know what happens when Dutch Bike Chicago heads over to Dutch Bike Seattle.
Watch until the end to see who forms the head. Who is that guy?
We've been repairing, maintaining, and
upgrading all types of bikes here at Dutch Bike since day one,
because while we love the somewhat exotic (here in the US, at least)
mechanical aspects of the bikes we import, one of our core beliefs is
that the best bike is the bike that you ride,
whatever it is. Whether we're installing custom fenders on your 90's
Bianchi racer or overhauling your 1976 Schwinn cruiser, we love
keeping bikes on the road.
Particularly
in the past two or three years, I've seen a massive upswing in the
numbers of bikes being brought out of storage, bought used, or
restored for everyday use. All types of reasons – economic,
practical, or ethical – bring these faithful steeds back into
harness, but my favorite of all is that it just seems to have become
cool. With increasing
numbers of bicycles on the road – many of them seeing their second
tour of duty – every shop is seeing an increase in repair traffic
and, more relevantly, more people are becoming acquainted with the
world of bike repair.
For
many, getting a bike repaired can be even more intimidating than
“taking the car in.” I will be the first to admit that bicycle
service shops do not have a stellar reputation for friendliness or
customer service, and even though a bike is less complex than a car
it can still be an opaque and mysterious opponent when it's not
working properly. For these very good reasons, a large number of my
service customers don't come to the shop for anything as specific as
wheel truing or derailleur hanger alignment, but rather for a general
tune-up. It might be every few hundred miles or every few years,
depending on where and how you ride, how your bike is designed, and
how it's stored and cared for. Whether your mechanic calls it a
“tune-up” or a “general service” or a “maintenance
package,” the basic idea is the same: make
my bike work so I can keep riding it.
You drop your tired, creaky steed at the shop, and a day or two
later you pick it up shiny and ready for another ride. What actually
happens to the bike, though?
As
you've seen in previous posts, I enjoy few things more than deflating
the fear and mystery around the technical side of bicycles, and so
today we'll walk through exactly what goes on during a tune-up.
Different tune-ups will include a variety of different operations
(wheel truing, adjustment, part replacement, etc.), and different
shops will provide a sometimes bewildering variety of options and
levels of detail. The tune-up you'll see here is our
“Comprehensive,” usually best for older bikes or commuters with
medium to high mileage. If the bike requires less I'll suggest a
less in-depth “Standard” or “Basic,” or simply perform a few
adjustments a la carte.
First, I'll remove
the wheels to make cleaning the bike easier and because I'll be
working on them individually later. I'll spray and wipe down the
frame and components with a weak cleaning solution (I like Simple
Green), because it's much more pleasant to work on a clean bike.
Now for the wheels:
cleaning first, then truing and balancing spoke tension.
Next I'll open the
hubs to check the bearings and inject fresh grease. When I put them
back together, I'll be sure to adjust them so that they'll spin
smoothly when they're installed.
Back on the bike,
I'll do the same to the headset and bottom bracket bearings if they
can be serviced. Before I reinstall the wheels, I'll sand and pick
debris out of the brake pads for stronger and quieter braking.
Now that the pads
are clean and grippy, I'll adjust the pad position and spring tension
of the brakes so they'll work powerfully, quietly, and drag-free.
With
the brakes “dialed,” I'll move on to the derailleurs; adjusting
the cable tension and limit screws, and the position of the
derailleurs themselves to optimize the speed, smoothness, and above
all the accuracy of each gear change.
Finally, I'll check
the tire inflation and take the bike for a test ride to make sure
everything is working perfectly!
As you can see,
there's no mystery and no magic here, but the proper tune-up should
have your bike riding like new – or at least close to it – and
keep you going for plenty of rides. Having your bike tuned may not
be the most glamorous, but the cumulative positive effects of a
smoothly functioning bike can be far-reaching!
This is Brian, the lead Barista at the new Dutch Bike Café that is located right in the heart of old Ballard in the Dutch Bike Co. Take a break from shopping for your Workcycle or a Bakfiets and check out our new coffee locale! I’m excited to let you know about the refined focus on coffee and espresso in our warm and inviting new café.
We are using locally roasted Lighthouse Coffee, and getting compliments and winning loyal regulars right from the start. The espresso profile is rich and warm with lingering notes of cocoa and a dry finish, much like a good red wine. To showcase the fresh roasted beans we are offering great drinks like the macchiato: which is espresso with a touch of steamed milk. We call it “the world’s tiniest latte." The doppio -- simply a double shot of espresso in a cute little cup & saucer -- is another great way to savor the flavor of the espresso. If you’re a traditionalist we have piping hot French press coffee all-day for your “drip coffee” experience.
Pair any of our great espresso drinks -- like the cinnamon and vanilla infused cappuccino -- with a lunch sandwich hot from the grill or one of Julie’s famous Salted Chocolate Chip Cookies and you are in for a tasty and enjoyable treat!
Plenty of folks are stopping in for a cup of morning joe and a breakfast sandwich. We also see a lot of you swinging in with your bikes for a tune-up and to test ride the great selection of bikes at the shop and to have a latte with friends.
Stay tuned for more updates on our fabulous baked goods, ice cream sandwiches, and espresso delights!
Some of us bought our bikes because we
wanted to be mobile. Some because we find them so very pretty. Some
because they're so comfortable. For whatever reason you purchased
your Dutch- or Dutch-type bike, if you got even a reasonable
imitation of one you benefit from how little they demand in terms of
maintenance. In previous posts we've walked through repair
operations that you (or your trusted mechanic) might have run into in
the course of owning the bike (tire and tube repair, shifter
troubleshooting, etc). In this post, I'll walk through a large
component of simply caring for your bike: lubrication.
In many ways, the chaincase defines the
proper city bike. It makes them compatible with any wardrobe, and
it's one of the main reasons why these bikes essentially don't have
to be treated like a bike. They can be left outside in the rain and
snow (and salt, if you're our Chicago shop bakfiets) every night of
their lives, and won't punish you for it. That said, since your bike
can last your lifetime, you'll want to take care of it to the minor
extent it requires. Chain lubrication won't quite be your most
frequent maintenance operation, but it's extremely easy and takes
very little time. Once every nine months will be enough under even
the most adverse conditions.
First you'll want to pick a chain
lubricant. The thicker and stickier a lube is, the longer it will
protect the chain, but stickiness attracts dirt. This leads to a
constant dilemma when maintaining an exposed drivetrain; balancing
how much grime covers my drivetrain and legs with how quickly my lube
washes off when I ride in the rain or mud. Because the conditions
inside a chaincase are so much cleaner and drier than the world
outside, we can get away with using an extremely sticky, persistent
lube that would attract a large amount of dirt and grime were it
exposed. It will take a little longer to soak into the spaces inside
the chain links (the only area where it actually does
anything), but since we're only doing it once a year or so...that's
okay. On a city bike, the tiny, tiny bit of extra drag introduced by
a heavier lubricant will be imperceptible to even the most sensitive
rider. For the most persistence, I recommend Finish Line Wet; a
heavy, sticky synthetic formulated to stick to exposed chains through
the nastiest conditions. It's also a beautiful shade of dark green.
Dumonde Tech Original (the blue one) can be a fair substitute.
Inside a chaincase, you can expect a heavy application of one of
these lubes to last most of a year!
Lighter lubricants
are just fine, but won't last quite as long or protect as thoroughly.
That said, lighter oils and oil suspensions like good old Tri-Flow
or Dumonde Tech Lite (the yellow one) can be quite useful for
lubricating and providing a water barrier for your cables. Spending
a few minutes letting the handy principle of capillary action pull
drops of well-shaken Tri-Flow into your cable housing can not only
substantially reduce drag and improve performance, but when applied
thoroughly enough can also prevent the unfortunate wintertime
disorder known as “Chicago cable freeze.”
Isn't physics
great?
While they have
some handy benefits, wax-based formulas and solvent-suspension “dry”
lubes don't have much of an application on the mechanical systems of
your city bike. Because they don't protect the chain as effectively,
and because their dirt-shedding properties aren't necessary within
the protected environment of the chaincase, wax lubes shouldn't be
used. Neither type will work at all well within cable housing, so
best to save them for your sporty bikes...if you must use wax at all.
Once you've chosen
your formula, all that's left is applying it! The vast majority of
you won't need any tools for this, except you bakfiets and Secret
Service owners. You'll need a one euro coin, large flathead
screwdriver, or other prying device to encourage the lower rear
section of your plastic chaincase to pop loose.
All you with fabric
chaincases need do is simply unsnap the snap.
Now
that your chaincase is open, you can inspect your chain's lubrication
and tension (refer to the rough guide in the last post for tension).
If you cannot see lubricant on the chain – or if you see any
corrosion – you should apply some. Nose the dropper tip or
extended straw/noodle of your bottle into the chaincase until it's
just touching the rollers on the inside of the chain. Carefully spin the
pedals backward while gently squeezing the bottle enough to run a
bead of lubricant along the chain, letting it soak into the spaces
within the chain and coat the moving parts.
Continue this
process until your chain is thoroughly soaked in lube.
Congratulations, you've lubed your chain! This would also be a good
moment to lubricate the shifter cable as it leaves the housing.
Welcome back, class! Now that you've adjusted your Shimano Nexus hubs, we'll dive into the next most interesting operation on one of these bikes: rear wheel removal. Mastering this will allow you to replace tires or tubes that are worn out or damaged beyond patching. This will get a little more technical than the previous post, so it's very important to make sure you're comfortable using tools and that you have the time and energy to safely put everything back together. Please read through the entire post before tearing apart your bike, and be sure you're comfortable performing all the operations described (especially tensioning the chain!). Troubleshooting and adjusting your hub didn't require any tools, but this will, so get out that toolkit and polish up your:
15mm open-end wrench or 15mm deep socket w/ driver
10mm open-end wrench and 10mm socket w/ driver (you can substitute another 10mm wrench or a small adjustable if necessary)
Cable cutters (diagonal cutters or wire cutters can be substituted)
2mm hex key/Allen wrench
Dental pick, sharpened spoke, sturdy ballpoint pen, small switchblade, or something else with a nice point to it
Tire levers (if you plan on replacing tubes or tires)
Now that your tools are prepared, set your bike on its center stand (or clamp the seatpost in a work stand if you're lucky enough to have one).
We will remove the rear wheel first because it's a more complex operation and many of the steps will be duplicated in removing the front. As an overview, we're going to disconnect the brake, open the chain case, disconnect the shifter, disengage the chain tensioners, and remove the wheel. Then we will reinstall the wheel, engage the tensioners, tension the chain and center the wheel, reconnect the shifter and brake, and close the chain case.
To disconnect the brake, first loosen the cable fixing nut several turns. Pull or clip off the cable tip, and pull the cable out of the brake.
Now once we've removed the torque arm clamp bolt the brake will be completely disconnected.
After that, move back to the right side of the bike and open the chain case, starting by unhooking the tension wire running along the bottom of the case.
Once the wire is unhooked about 3/4 of the way down toward the front, unsnap and unclip the rear section as we did in the previous post.
Now loosen the axle nuts about three turns (Don't worry, the chain tensioners will hold the wheel in place) and yank the rear section of the chain case frame straight back and out of the bike.
Shift the bike into first gear, and poke the long end of the 2mm hex key into the tiny hole in the back of the cassette joint.
Pull downward on the wrench to give yourself some cable slack, and then use your pointy tool to pop the cable and cable stop out of the cassette joint.
Pull the cable housing out of the housing stop, being careful not to kink the cable.
Now that you've disconnected the brake and shifter cables from the hub, all that's left is removing the wheel itself! Loosen the chain tensioners until the nuts are even with the end of the threaded section, and loosen the axle nuts until the colored non-turn washers (yellow on the right, brown on the left) can completely clear the frame.
Lift the chain carefully off the teeth of the cog and set it down on the plastic of the cassette joint.
Now you'll actually remove the wheel: pull it straight backward until both chain tensioners are loose enough that you can flip them downward so that they hang from the axle.
The wheel will now be free to slide forward and out of the dropouts, and you're free to replace tubes, change tires or just marvel at your accomplishment.
To reinstall the wheel, you will essentially be reversing most of the steps you've just completed. Set the chain on the cassette joint -- next to the cog but not on it -- and then slide the wheel back into the dropouts. This may take some wiggling, and possibly even some fiddling to make sure that the chain tensioners are inside the dropouts, and the non-turn washers (brown and yellow) are outside. Gently pull the wheel as far back into the dropouts as possible, giving yourself enough slack to flip the tensioners back into place. Now that the wheel is held in place by the tensioners, you'll be able to reattach the shifter and brake cables, the chain, and the chain case.
Set the chain back on the cog and carefully turn the cranks a few revolutions to make sure that the chain is fully set on the chainwheel (front gear) as well. To reconnect the shifter cable to the cassette joint, first slide the cable housing end into the housing stop.
Now repeat the trick with the 2mm hex key to wind the cassette joint back to a point where you can slot the cable stop into its cradle, making sure that the cable sits cleanly along its channel. Shift up and down the range a few times to make sure that everything is working smoothly, and also use this opportunity to check the adjustment of your hub (just like you learned to do in the last post!).
Pass the brake cable through the housing stop and into the cable stop, tightening it down at at its original setting. Make sure the housing is fully inserted in the stop. At this point you can crimp a cable end cap onto the cable, then test brake function by pulling hard on the brake lever.
Slide the rear section of the chain case frame into place, carefully pushing both top and bottom ends into place in the main chain case frame. Be sure that the chain tensioner is outside the chain case frame on the axle.
Now that everything on the axle is in place, you can tension the chain. This step is going to be the most technical that you'll perform during the operation, so shake the kinks out of your hands and get ready! Tighten down the axle nuts until the tabs of the non-turn washers are fully inserted into the dropouts, but not so tight that you can't shift the wheel. Throughout this step, you'll be keeping the wheel centered in the frame by watching the distance between the (ideally fully inflated) tire and the chain stays. Tighten the chain tensioner nuts evenly as you bring the wheel back toward its original position. On Workcycles bikes (especially if you are using the original cog size), you'll frequently be able to find this spot by the indentations left by the non-turn washers in the frame powdercoat.
Ideal chain tension can be an art and a science, but the easiest gauge will be this: at the tightest spot in the rotation of the cranks (because there will be tight spots and loose spots) you should still be able to move the chain slightly (<1/4") up and down with your fingers. You should NOT hear a crackling sound as you spin the pedals through the tight spots, and the chain should not be so loose as to hit the bottom of the chain case.
Once you've got the chain at a nice tension, double-check the centering of the wheel and then reattach the rear brake's torque-arm clamp on the chain stay.
Now you can tighten down the axle nuts! Make sure these are solidly tight, really get your arm behind the wrench (unless you're some sort of giant burly guy, in which case you'll want to exercise some restraint).
Now that the wheel is reinstalled and the chain case frame is reassembled, most of what's left should be familiar from the last post: closing the chain case. Gently (because these are fabric parts, after all...) slide the rear section of the cover over the frame, keeping the chain tensioner outside. Pull the edges of the inside slit (between the wheel and the chain case) together and slide the prongs of the clip into their pockets inside the chain case. Snap the snap on the outside, and hook the wire back and forth across the hooks on the underside (don't miss any!).
Thanks Mark! That might just be the next post...but until then, just undo the screws holding the lower half of the chaincase together, gently spread it enough to pass the chain out and pull it off the bike, and you're ready to go. The plastic chaincases are nice and simple, if not quite as classic as the cloth.

I'm awaiting my bike at this time, a 65 WC Kruisframe in matt black, from the Chicago store.
But I wanted to say how much I appreciate you doing such a great, clearly written and illustrated post.
For me, residing outside Lansing MI and nearly 4 hrs travel to Chi-town, having this and subsequent guides for routine maintenance is a real asset, as I can't just run down to the store.
Thanks -

Hi,
Thanks for the post. I have a Gazelle here in Holland and working on the rear wheel is a bit perplexing. If you have time a video post for removing and installing the rear wheel would be great!
We agree a video would be helpful, look for it soon...

So in order to replace a rear tube mid-trip this is what I have to bring along ? Wow, I did not realize how in depth this effort was compared to a skewered rear wheel with derailleur. Kinda on the fence now about getting a dutch bike.
Goodness no! That really would be a ridiculous sight next to the road, wouldn't it? Actually all you need is a patch kit and an inflation device, since -- on the road, at least -- you'll just be patching the tube in place.

Wow! This is really great!! Would you consider posting information on how to change the back tire of a Gazelle Toer Populair 3-speed? Since it has the rod breaks and a different hub, I was wondering what the differences would be with this bike. Could we mostly follow your directions with a few tweaks?
@Kerry: You should be able to to unhook the rod from the drum brake actuator arm without even loosening the adjuster. Aside from that, the only challenges you may face will come from getting past the rack to close the chaincase, but that just takes fiddling. Be careful with the threaded rod and shifter chain, and have a great time!
