Modern Snow Bike

K-Trak Snow Bike System

In my two previous posts, here and here I have looked at 100+ year old ideas for how to get around on a bicycle in the snow and ice. Aside from the simple approach of using studded tires on a bicycle (which works for most urban snow) there is also the above snow bike inspired by a snowmobile.

1896 Ice Bike Demonstrated by Woman Rider

Short article about ice bike demonstration in The San Francisco Call, January 19, 1896.

An Ice Bicycle.

A bicycle has been invented for traveling on ice or snow, says a New York paper. The long runner or skate, which replaces the front wheel of the bicycle, in itself is made for ice alone, but when the machine is used on snow-clad roads a metal shoe is fitted over the skate, and it is claimed that the machine will carry a rider over the ground, or rather snow or ice, at a greater speed than the regulation wheel.



Miss Davidson, who is young and enthusiastic, mounted the ice wheel at a rink last evening with but little difficulty, and, after a few "wobbles," started off around the rink gracefully. The half dozen spectators were astonished at the perfect work ing of the machine. After two or three turns about the rink Miss Davidson did a few fancy moves and then dismounted.

Converting Bikes to Snow/Ice Use - Patents

Snow Bike Patent, 1900

"The invention contemplates the employment of a bicycle of any preferred style, in combination with supporting sleds or runners and means for imparting motion thereto." and . . . "The rotary motion of said shaft is converted . . . to a reciprocating motion upon the part of the push-bars, which are alternately projected and retracted, engaging the snow or ice at each stroke, and so propelling the vehicle."

Apparently the idea was to propel the bicycle as though it was someone's crazy version of a cross country skier, in which the poles do all the work.


Snow Bike Patent, 1900 - augmented wheels

To make this work, rather elaborate changes are made to the tires, fixing a set of teeth to the outside edge of the tire. Uhm, wouldn't it have been easier to run the chain down directly to do this??

The "ice velocipede" below looks more sensible, although since it preceded the above by six years, apparently it hadn't caught on.


Ice Velocipede 1894

The object of the invention is to provide a new and improved snow and ice velocipede, which is simple and durable in construction, and arranged to enable the rider to travel over the snow and ice at a high rate of speed. and The invention consists principally of single front and rear runners supporting the frame, and connected thereto by horizontal pivots and a propelling chain mounted to travel along the rear runner and driven from the crank or pedal shaft through the medium of a sprocket wheel mounted on the pivot connecting the said runner with the frame. (Crazy way to write.) and The propelling chain is provided with spikes or blades adapted to pass into the snow or ice, so as to propel the vehicle forward. Aha! Well, it might work. But again, we don't see these around . . .


Snow Shoe Attachment for Bicycles

This is the simplest of the bunch, although it seems likely to have traction problems.


Traction Vehicle

This isn't actually a patent for a snow bike (snow isn't mentioned in the patent) but rather a tracked bicycle that could, presumably, have been used on snow as well as on other difficult terrains. (Also it seems to be a purpose build device rather than a conversion.) Could this be used for cyclocross? Again, we don't see these around today, do we. Presumably the energy required to get this to move at all was a bit of a problem.

Keep in mind these are 110+ year old patents - what is interesting is that there are plenty of patents from the last 20 years that aren't that different. Go to Google's patent search and simply search on "bicycle snow" and see what I mean.

Washington Post Doesn't Know What Bike I Want

Recent ad on WashingtonPost.com providing a crazy assortment of bikes

I have burst out laughing when I have spent ten minutes gazing thoughtfully at some bike wheels on Amazon.com and then a while later, a sidebar ad on WashingtonPost.com tries to interest me in the very same bicycle wheels on Amazon.com. Well, uhm - I haven't changed my mind, as a matter of fact. Still don't want them.

This assortment, however, was quite amazing. What algorithm is behind this sort of thing?

A road bike called the "Tour de France" for . . . $209.99. Well, sure if you want a bike that allows you to answer the question, "do you have a bike" in the affirmative but don't plan to ride it. Because that's what a bike like this is intended for - not being ridden.

Then next up, a Pinarello Dogma - only $13,200!! What ?!? I don't pay attention to this market, so I can't say if this is a "good" price or not but that I'm not buying any bikes that cost more than the last new car I bought, I'm pretty sure of that.

Logically what should be in the third position here after the total crap bike and the bike that was hand carved by the most experienced Italian carbon-fiber-carvers would be the "just right" bike priced somewhere in the real world at around $800 - $1,200. But no, the algorithm goes completely off the rails and offers an even crappier bike. Regardless of price and anything else, there can be no worse a bike than one that is named after a car - and not just any car, but a monster SUVs, the GMC Denali. Who buys bikes with names like that? (I am not denying

I guess I should give them credit for somehow detecting my interest in road bikes over mountain bikes, but other than that this seems pretty clueless.

Don't get me wrong, monster SUVs have their time and place. But I have trouble seeing the connection between one of them and a road bike, in a good sense anyway.


On a visit to Iraq some years ago, GMC Suburban vehicles made sense for my travel plans - otherwise not so much

Latest In Bicycling Costumes for Women (1895)

From a long Los Angeles Herald article from August 4, 1895.


Illustration that accompanies the article

SHE DESIGNS BICYCLE SUITS - That is How a Chicago Woman Is Coining Wealth - SHE IS AN ARTIST IN THIS - Tells Fair Bicycle Riders the Kind of Clothes They Ought to Wear. Says Bloomers Will Soon Be the Street Costume.

This article is quite long, so I will only reproduce some of the text here - the full text is available in the online digitized version.

A clever little woman on the West Side is proving herself a benefactress of womankind and, at the same time, earning a good living. Her name is Helen Waters. She designs bicycle costumes for women, says the Chicago Times-Herald, Mrs. Waters is a petite young woman with big brown eyes and a "wide, kind smile." She is extremely brisk and energetic, and possesses some original ideas as to the proper garb for women who ride. She is a member of the Illinois Cycling club, and is a skillful and rapid rider, although she does not aspire to record-breaking honors.

. . . . .

"Do you mean to say that bloomers will be worn us a street costume next summer?"

"I don't wish to be too hopeful, but things look that way to me. I, for one, will be glad if it is so. A woman who has once worn bloomers dislikes to put on skirts. I know it from my own experience and that of others. As you see, I wear them about the office all the time and have even ventured to wear them on the street cars to and from my home. However, occasions arise when 'discretion is the better part of valor,' and then off go bloomers and on goes the skirt. I hope you won't laugh at me when I say I find the skirt uncomfortable."

This kind of cycling human interest story was common during the high years of the cycling craze in the 1890s. The article is about a woman in Chicago but was published in Los Angeles, likely published in numerous cities through some then-publication network for these kinds of not-very-time-sensitive stories. This particular story had two different elements of interest - the subject's changing of women's attire and her financial success, earning a "good living."

Cracked Rim & Brake "Dirt"

Riding in snow and ice even with studded tires can be challenging - also if one has any sense, it is important to clean up the bike fairly soon after to get the road salt mix residue off the bike. Wheel spokes in particular are vulnerable to the corrosive effects of that stuff; I am embarrassed (I guess) to admit that one year I rode in some bad weather and then parked the bike in my shed and forgot to clean it - much later I discovered the road glop had eaten its way into several spokes enough that when I gave them a wiggle, they snapped! Lesson learned. Ouch.


Crack discovered while cleaning the rim

So I took the old mountain bike (a Giant Boulder SE, more than ten years old) that I rode in the snow and cleaned it up and while cleaning the rear wheel I found that the rim had a crack in it. Aggh! What I actually had found, as revealed in a helpful comment (below) is an artifact of the manufacturing process that I had not noticed before. Oops.


Not surprisingly the crack goes through to inside of rim

Fortunately I have another mountain bike around that I can borrow a wheel from, but I will have to buy a new wheel.


In gloppy weather, brakes make a mess of rims

I didn't need to clean the other side of the wheel now! You can see just how much of the brakes end up on the rims in sloppy weather. I suppose I could buy better brake pads, too.

Anyway, this provides something of an answer to the question of why one gets something better if you spend more on a bike. This is a perfectly OK entry level Giant mountain bike but aside from being fairly heavy none of the components are terribly good (although none are terrible, either). In short I am not particularly surprised to have a cracked wheel on a bike like this. The question arises, at least in my mind, of whether I now take back this comment about low cost bikes and their quality quotient. After some ten minutes of contemplation (intermittently) I guess I would have to say no. I don't.
