Wildlife on Urban Cycling Travels

Hawk (?) or Falcon on Four Mile Run
Falcon - or Hawk? - on trail along Four Mile Run in Arlington VA

Saw this today - remarkable how much wildlife I see along streams on trails around here. This was no more than 100 yards (meters) from the 395 interstate highway going into Washington DC. And I saw a rather large fox while walking our dog this morning!

Peculiar sort of advertisement - only the man's bike is properly visible, and even it is not shown in much detail. The front of the woman's bike is obscured and the child's bike is not visible at all. (At this point serious children's bikes were not much of a market since the cost was rather high for something for a child.) It is also interesting that the emphasis here, in 1896, is on where you can go with the bicycle and doesn't show the cyclists riding the bicycles.

1896 was the height of the so-called "bicycle craze" of the 1890s.

The digitized version is not of very high quality since it was digitized from a photographic reproduction of the original item. That is why it has the color bar and rulers.

1897 bicycle illustration "What Happened?" detail
Detail from the above illustration

Above is a zoomed in view of the bicycle taken from the TIFF image - the level of detail, because this is digitized from a reproduction and not the original illustration, is not particularly good but at least provides enough to show that the person doing the illustration captured accurately the details of an 1897 bicycle.

You can tell it is a "fixie" as it would be called today - that is, the chain drive doesn't spin freely when the rider is not pedaling, the pedals move in concert with the back wheel. The easiest way to slow down or stop was simply to slow down or stop pedaling. This bike has a small post on either side of the front fork that stick out so that a rider could remove his feet from the pedals and rest them on the fork to allow the pedals (and rear wheel) to spin freely while descending hills - getting the feet back onto the pedals was tricky, but this bike also came equipped with a simple "spoon brake" that is visible - that is, a levered brake actuated by the right hand that pressed a post downward to the front tire, pressing a block of some material (perhaps also covered in rubber) against the tire to slow the bicycle. This can be a moderately effective braking system but if used frequently it was hard on the front tire. Certainly it was better than nothing! (And such brakes are still in use on bikes in many parts of the world.)

Another detail provided is the bicycle saddle - a non-standard bicycle saddle was a common aftermarket upgrade for bicycles in those days. Here the saddle is split in the middle, apparently to provide more comfort (or something). Such bicycle saddles remind me of the slotted McClellan saddle for riding horses used by the military that have a slot down the middle. As a teenager I occasionally rode a horse using such a saddle and didn't find it very comfortable, but the slotted nature of a bicycle saddle is less rigid and usually comfortable enough. Still, I don't have a good association with slotted bicycle saddles.

Dockless BikeShare Bike Hiding From Riders in Plain Sight

Little Lost Dockless Bike
Parked at this location on a busy street for a full week

This bike arrived at this location last Sunday morning. (The photo was taken from the local multi-use trail across the street from the bike that is heavily used by walkers and cyclists.) It is at South Wakefield St and South Walter Reed Drive in (South) Arlington, VA, at a bus stop. Biking by most direct route, it is less than ten miles from Capitol Hill, which is the middle (assuming you look at it that way) of Washington DC. Not the distant suburbs, but not a quick bicycle ride either.

For the "docked" Capital Bikeshare system, this area is at the edge of the present network of bikeshare docks. The nearest station is now about one-third of a mile away. There are about (per https://www.capitalbikeshare.com/how-it-works) 3,700 Capital Bikeshare bikes available across the metro DC area with this network.

This orangy bike is part of Mobike's dockless bikeshare. In the DC area, Mobike has started with 400 of their "dockless" bikes. Mobike ("the world's largest smart bike sharing company" they say) has a press release with some details of their plans.
Mobike is a re-imagination and delivery of the ultimate urban bicycle with innovations such as the chainless shaft transmission, non-puncture airless tires, a lightweight aluminum anti-rust frame, an enhanced and durable disk-brakes and an auto-inspired five-spoke wheel. These functional design elements result in a maintenance-free bike, with each Mobike’s lifespan estimated at 4 years of fix-free cycling. Each bicycle is connected to the Mobike IoT network via GPS-embedded smart lock; forming one of the largest IoT networks on the globe.
Some of this isn't accurate for DC - apparently Mobike bikes are usually single speed bikes with a shaft drive (no bicycle chain, but rather a drive shaft like a car). Here, in their first US location, Mobike decided to have a three speed gear system and apparently for the time being they aren't able to combine a low cost durable three speed hub with their shaft drive system, so you get a bike chain (with chain guard to keep chain grease off clothes). Some of it sounds good in one way but is more about reducing the company need for bike maintenance than anything else - as they mention, they hope for "4 years of fix-free cycling." (Four years without lubricating the chain will be . . . interesting.) So the "non-puncture airless tires" (by which them mean flat proof) are mostly about avoiding any company time spent fixing flat tires and not because you are going to prefer the ride of a bicycle with hard tires. (Part of the genius of the basic bicycle design is that the shock absorbing system is built into the inflatable tire, which is mostly not possible with airless tires.) And the "auto-inspired five-spoke wheel" (that has five pairs of spokes, or ten spokes, but OK) is also about low maintenance since unlike regular bike spokes, no maintenance or adjustment of spokes like these is even possible. (The idea that people using bicycles want something inspired by automobile design is curious.)

To get back to the subject at hand. Mobike's PR continues:
Mobike’s distinctive silver and orange bikes will be initially deployed at key downtown locations such as DC Metro stations, university campuses, and public parks. To use the service, users simply need to download the Mobike app, register, and scan the QR code on the bike.
While they may have been "deployed at key downtown locations" this one has been ridden to an obscure South Arlington location where hundreds if not thousands of people have seen it there. Since use of the app is presumably still becoming commonplace, in the course of a full week no one has been interested in using this thing. And Mobike, which is presumably seeing it with their gigantic "Internet of things" network, can't be bothered to move it to some place where it might be useful since that would cost money.

Is there anything seriously wrong with this scenario? Not sure.

Post Script: After a week and a day, the bike disappeared from that location. Perhaps the Mobike people reacted to my tweet (to them) on the subject.

Dockless Bikeshare Parking Example

MoBike in front of Library of Congress Madison building
MoBike in front of Library of Congress Madison building

The most recent rider left it near the front door. The nearest bike rack is about 100 feet away, just barely visible in this photograph (if you click on it and zoom in). As it happens, the nearest bike racks were all full, but a plaza like this isn't intended for bike parking on a random basis like this.

Part of My Commute on YouTube



Someone's video of the trail I use for several miles of my commute. The video starts where I join the trail on my commute.

I understand why the camera angle is the way it is, to show the area traveled through more fully, but this doesn't show very well the condition of the trail itself and how (for example) the width varies. The last mile or so (starting around minute 11) shows the most recently "upgraded" part of the trail that is wider than most of the trails around here, but this isn't obvious from the video (alas). I also find it disconcerting when the video is playing at 300 percent of actual speed. . .
