On The Hook: Old Inner Tubes

Nearly two weeks ago, I mentioned Nicolas Collignon's article, in which he expresses consternation and frustration that "sustainable" urban and transportation planning, too often, doesn't include bicycles.

The other day, I wrote about a rather surprising (in that someone hadn't thought of it earlier) way transportation cycling and sustainability have been integrated:  bike lanes with solar panels in the Netherlands and South Korea.

Today, I am going to present another, if smaller, way in which cycling and sustainability meet.

What I am about to describe is also rather surprising, but not because it hasn't been done before.  Rather, it seems almost-unexpected because it's an idea that seems to be revived and forgotten every few years--and because many people don't remember, or weren't paying attention to, its previous iterations.  What also makes the fact that it's not more common so surprising is that, even with all that we toss, I think we, as cyclists, are more conscious of, and conscientious about, recycling than most of the public.

Lots of replaced bicycle parts are tossed out every day, by shops as well as home mechanics.  Most, I imagine, end up in landfills.  Some, like old cables and housings, are difficult to re-use because the metal is rusted or has lost too much of its strength from the stresses of use.  But other parts can find new life in all sorts of ways.

One such part is an inner tube.  On my Bontrager Race Lite Mountain bike, I strapped a Pedro's under-seat bag made from an old air chamber. In it, I carried--you guessed it--a spare inner tube in addition to a patch kit, tire levers and the great Park mini-multitool. I've seen other accessories made from old tubes and once even wrapped a pair of handlebars in them.

Another way I've used inner tubes are as tie-downs. Think of a bungee cord without the hook:  I've strapped small loads to rear racks and have bound together all manner of items, on and off the bike, for any number of purposes. 

I'm sure I'm not the first to have used old inner tubes in that way.  But it took someone with a more inventive or entrepreneurial mind than my own to come up with the Daily Hook.





It's what it sounds like:  a section of inner tube with a hook at the end of it.

The difference, though, is that the hook is better-made and more practical than any you've seen on a bungee cord:  It's machined from aluminum and fits onto the end of the tubing section through a stainless steel backplate.  I would imagine that it allows the hook to be re-used on another section of tube when the original one fails.





Speaking of which:  Daily Hook's Swiss manufacturer claims--correctly, in my experience--that the tube section will last longer than fabric cords, which have a tendency to unravel or break.  And, if and when the tube does fail, the hook won't get tangled in your spokes or cogs because it has a spring clasp that holds it mechanically to your rack or wherever else you attach it.  Moreover, if your rack is anodized or painted, the finish won't be marred, as the hook is coated in grippy rubber.





The Daily Hook weighs about the same as an elastic cord of the same length.  Its only drawback, as far as I can see, is its price, though if it outlasts a bunch of fabric cords, it could be worth the investment.

And, of course, it gives old inner tubes new life.

Where Cycling Really Means "Power To The People"

A bit more than a week ago, I mentioned Nicolas Collignon's article, in which he wonders why bicycles aren't in planners' thoughts about sustainable transportation and other aspects of urban planning.

A bit more than a year ago, I described one of the rare examples in which transportation cycling has been made a part of sustainability planning:  a bike lane with solar panels in--where else?--the Netherlands.

Well, I have just learned of another bike lane with solar panels--in South Korea.  The Asian path, however, is not only much longer (about 32 km vs 330 meters), but also has a very different design from its European counterpart.

The Maartensdijk ribbon has solar cells embedded in its prefabricated concrete blocks.  The lane from Daejeon to Sejong--the country's administrative capital--sits in the middle of a major highway and is segregated, not only from that highway, but (at least in part) from the elements.  That lane is covered by a series of canopies of solar panels, which, its designers say, not only generates clean energy, but also encourages cycling in less-than-ideal weather conditions--and shields melanin-deficient folks like me from the rays that are being harnessed for power.

The Korean bike lane has been open and widely used since 2014.  Given all of the talk about sustainability, I wonder why so little attention has been paid to it.

I also wonder why there aren't more similarly integrative solutions to the problems of sustainability.  And, like Nicolas Collignon, I wonder (actually, I know some of the reasons why, but still...) why bicycles aren't included in the first place, especially here in the US.

A New Use For A Dutch Bike Lane

 If you’ve ridden with a dynamo-powered light, you’ve converted your pedaling power into electricity.  Some cyclists have also turned their RPMs into amps that ran everything from toasters to tuners.

Now a Dutch province (where else?) is using the bike path itself to generate ecologically sustainable electrical power.

On Wednesday, elementary school students in Maartensdijk, a village near Utrecht, became the first to ride the 330 meter path. Its prefabricated concrete blocks are embedded with solar cells and coated with a transparent layer that allows sunlight to reach the cells as it protects the path.

Arne Schaddelee said, “you have to dare to use innovation” to reach goals like the one the Netherlands set for itself: being climate-neutral by 2040.  “And this is very innovative,” the provincial official declared. 

But it’s not innovation for innovation’s sake. “We have a very full province,” he explained.  “For that reason you have to try dual use.”  

His pronouncement could also apply to his country: The Netherlands is one of the world’s most densely populated nations.
