Henry’s Yankee Transportfiets

yankee transportfiets 7

I have to admit that I have a lot of bicycles, and I’m referring to bikes that are really just mine and not somehow part of the WorkCycles fleet or inventory. I periodically cull the flock but some have too much sentimental value to sell, even if I almost never ride them. There’s the Daedalus mountain bike from 1990, designed by me and built by Kent Ericksen of Moots in Steamboat Springs, Colorado. There were six made of which I still know the whereabouts of four. I don’t think I could ever see my lovely De Rosa go. I bought it a year or two old from a friend in about 1982 and raced and trained on it for years until breaking one of the silly diamond shaped chainstays. My friend Brian Spitz (who built some of the world’s cleanest race frames for a while) repaired it but then I hung it up and forgot about it for 15 years. A couple years ago I decided I wanted to get back on a racing bike, found it still wrapped in paper and built it up again. Now it gets ridden regularly, much closer to it’s birthplace in Italy. There are many others, in order of how long I’ve owned them:

  • Custom 60’s Schwinn Typhoon cruiser with Sachs 2-speed kickback hub
  • Bianchi Reparto Corsa road bike built (15 years ago) as a road fixie
  • Castle track bike
  • 1973 Libertas racing tandem
  • Snel touring bike, now my “papa bike” for touring with Pascal
  • 1957 Condor Swiss military bike
  • WorkCycles Secret Service city bike (the daily ride)
  • Brompton folding bike with 2 speed shifter and titanium parts
  • Those are all complete, rideable bikes. I also have a number of bikes in various states of incompleteness and a rather absurdly large collection of (mostly old enough to have no monetary value) parts. The semi-complete bikes include:

  • 1950’s Gazelle Opafiets
  • 1970’s Rih light city bike
  • 3x 1930’s Grossman transportfietsen
  • 2x Hopper (English) delivery bikes with cross-frames, perhaps 1930’s
  • 1970’s Gazelle racing bike, converted to randonneur
  • At least all of the old transport and city bikes are destined for the WorkCycles museum and a few are already on display. A few bikes including the city bike, Brompton, papa bike and racing bike are ridden regularly. Some of the others will return to service when the time is right. Amsterdam has, for example, a fantastic indoor velodrome and I’ve been itching to get back on the track, though that might have to wait until Pascal is old enough to ride too.

    Anyhow this is a long intro to noting that I got another bike. This one is a transportfiets (Dutch delivery bike) from the firm “Yankee” in Hoogeveen (where Azor is now and Union once was). I’d never heard of Yankee but that doesn’t mean much; until the 1960’s there were hundreds of small firms building bikes in the Netherlands. Lugs, tubing and components were bought in from various suppliers and the bikes were built from scratch. The quality was typically excellent but the designs were very conservative. Only experts can tell many of the bikes apart and little changed from the 1920’s through the 1960’s or even 1970’s in some cases. A few of the manufacturers were known for particularly high quality (Empo, Fongers, Gazelle, Simplex) and/or unique design (Fongers, Locomotief, Maxwell, Simplex). Yankee though has somehow disappeared into the gorges of history.

    What’s really new in bicycle world?

    Thursday, October 1st, 2009

    My friend Will Fleishell sent me a link to the great looking Metz Bicycle Museum in Freehold, NJ (USA). They’ve a broad collection of bikes, tricycles and quadricycles from early bike-dom (the 1860’s) to about 1900. Some look remarkably modern while others are of formats that have long since disappeared. Check out this tandem quadricycle that can be converted into no less than two types of high-wheeler bikes, for example:

    tandem quad

    The first bike that caught my eye though was this 1890 “lamplighter’s bike” from New York City. You see a 250cm bike was the perfect way to reach a flame into hundreds of streetlamps each evening. Just ride along and dab the burning stick into each oil lamp as it comes along.

    lamplighter-bike-new-york

    But wait a minute, you object, isn’t this just a “tall bike” like those weird anarchist dudes do their jousting on? Yes, exactly… except that they just reinvented it, uglier and worse, 100 years later. And this is exactly my point: Most of the real “invention” and “development” of the bicycle occurred more than 100 years ago, back when the bicycle was one of the pinnacles of technology, and certainly the highest tech thing an ordinary person could get their hands on. As I recall some of the things that were developed for bicycles: steel tubing, ball bearings, pneumatic tires, the tensioned spoke wheel, the roller chain drive and the list goes on. People often poo-poo of the achievements of the Wright Brothers because they were bike makers by trade, but this completely misses the point that the bicycle techies of that day were amongst the best suited to be experimenting with aerodynamics (which nobody understood yet) and lightweight, efficient structures.
    archibald sharp

    In 1896 Archibald Sharp wrote what is probably still the most comprehensive book on bicycle technology “Bicycles and Tricycles, An Elementary Treatise on Their Design and Construction”. It’s 400 pages of detailed analysis of bicycle design. From the MIT Press site (they reprinted it in 1979 and my copy is one of these):

    It begins with a general exposition of mechanical principles: dynamic, static, and straining forces. It then covers successive experiments at bicycle and tricycle design, including several “mechanical monstrosities.”

    With the aid of elegant, sometimes humorous drawings, the book examines various designs for their relative stability, steering advantages, gearing and resistance properties. The final selection discusses the design of individual components in detail, including the frame (from the point of view of stress analysis); wheels; bearings; chains and chain gearing; toothed-wheel gearing; the lever-and-crank gear; tires; pedals, cranks and bottom brackets; springs and saddles; and brakes.

    Even if you couldn’t read English or simply can’t be bothered to follow the scientific explanations the illustrations would be worth looking at. There are images and often scorching analysis of all sorts of bike and component designs that have been unwittingly (or knowingly?) reinvented in the intervening 120 years: disk wheels, belt drives, suspension frames and forks, shaft drive, two-speed epicyclic cranks and many more examples.

    Bicycles & Tricycles

    “Bicycles and Tricycles” is again out of print but it should be possible to find a second-hand copy. ISBN-10: 0-262-69066-7, ISBN-13: 978-0-262-69066-9

    My point isn’t that the bicycle hasn’t evolved in over 100 years; It certainly has but largely in details. The basics elements have long been well understood, and unfortunately seem to get forgotten regularly. Thus simultaneous with the evolution of brakes, gearing and other details is constant de-evolution and re-invention of the basic design. A few examples of how current bikes are often actually worse than their predecessors:

  • The generally too high crank axles that make it difficult for the rider to reach the ground when the saddle is adjusted to a biomechanically suitable height
  • Too wide “tread” (aka Q factor), the distance between the pedals… requiring higher crank axles
  • Inappropriate steering geometry on most city and utility bikes
  • Here is thus where we focus our efforts at WorkCycles; not attempting to reinvent the wheel, but merely refine it. This can require searching back a few steps to see where things went wrong (city bike ergonomics) or developing our own knowledge where there doesn’t seem to be any useful history to rely on (steering geometry for very heavily loaded bikes). All the while the designs remain timeless, but not for the sake of “retro style”. We’re either maintaining highly developed designs that are still fundamentally sound or creating new ones with the recognition that the products of evolution rarely fall far from the apple tree.

    Onderwater triplet tandem… decorated

    onderwater family triplet planted

    It takes some cojones to give your brand new €2000 family triplet tandem a spray can paint job and then cover it in cheesy plastic flora… but the results are certainly unique and effective.

    onderwater double tandem planted

    Why does the Amsterdammer do such a thing? Simple: Making it crazy and unique wards off thieves. Your bike is critical to getting around but at the same time not an object of obsession. The same family has ridden a similarly decorated Bakfiets Cargobike for years, probably appearing in thousands of holiday photos and blogs as a result. Now the kids are older and it’s time for them to contribute some locomotive force.

    Thanks to the kind WorkCycles customer for stopping by with the bike.

    four person tandem bike in amsterdam

    Sunday, May 17th, 2009


    four person tandem in amsterdam, originally uploaded by henry in a’dam.

    I can’t believe I’ve never come across this quadruple tandem before. I was parked on the Keizersgracht in the center of Amsterdam and looks as if it’s been there for years.

    It’s a sweet bike too: a Gazelle, probably built in the 1950’s or 60’s mostly from bakfiets and transportfiets parts. A few cool details:

  • all lugged frame construction
  • three eccentric bottom bracket shells of varying sizes to tension the chains
  • bakfiets rear drum brake operated by the last rider
  • motorcycle front drum brake
  • It’s also really heavy. I tried to set it more upright for the photo but realized that would have required a helper.

    Tweelingfiets (twin bike)

    Thursday, February 19th, 2009

    tweelingfiets 1

    tweelingfiets 2

    This is called a “tweelingfiets”. It’s a special Dutch bike for carrying multiple kids and this example seems to date from the 1970’s. At first glance it looks like a modified tandem but it’s not. It’s a “longtail” city bike produced in series around when most of the designers of current longtails and xtracycles were just a glint in their dad’s eye. That doesn’t detract from the Xtracycle and the growing crop of modern longtails, but does show that many ideas come around a few times… especially when it comes to bikes.

    I know of at least 4 firms that have produced a tweelingfiets but this type is the oldest. I’m actually not exactly sure who built these but I’m guessing Van Raam who builds or has built frames for a number of firms including: Gazelle, Grimminck, ‘t Mannetje and Utopia Velo.

    This particular bike, parked around the corner from my house, has a particularly nice arrangement of child seats. It’s very social for the kids in back. Quite ironically I saw it later today, but with a child facing forward on the rear facing seat.

    Now that I’ve been “collecting” these links for some time the reviews have become more balanced, covering a broader range of bikes than I first found.

    Here’s one more review in Dutch though its already three years old and wasn’t very objective to begin with: Fietsersbond bakfiets test. Its in Dutch and no direct link is available.

    Here on the “Groot Gezin” (big family) chat site there is a long thread with discussion about many of the child transport bikes and trikes. The focus is generally on the cheap bakfiets options and like any discussion the opinions are to be taken with a grain of salt. Dutch Language.

    Does anybody have any suggestions, particularly about other well-known bikes such as Nihola and Christiania? Please keep the discussion to family transport bikes and not transport bikes in general.
