Longest night

Today is not only the shortest day of the year, it's also the longest night. People all over the world celebrate this fact on December 25th, the date when nights begin to shorten again. It is therefore halfway through bike light season. What better time to write a few light thoughts?

For a few years I've been very happy with my Exposure Diablo light. It's very small, devastatingly bright, and can be mounted on either my handlebars or my helmet. On the helmet I can aim it directly where it will do the most good, which is sometimes directly into the vision of someone who might not otherwise know I'm there. But mostly I keep it on my handlebars, and the battery life is fairly short on retina-searing settings so I save those for off-road use.

Mine still works as good as ever mostly, but the switch is a bit fiddly and hard to turn off sometimes. It came with a quick-release mount that has worn and now rattles, as does the second one I got so I could use one light on two bikes. I have the third version of this awesome light, which is now up to version seven, and I was considering replacing my old one with the latest model until I looked at the current price. Yow!

So I turned the the universal catalog to see if any alternatives exist, and I'm happy to share the one I've been testing.

WindFire Wf-501B, with charger and mount
This generic flashlight puts out just about the same light as my good old Diablo, both in intensity and beam shape. The included clip works fine and is easy to move from bike to bike. I use it under my handlebars in a way that might knock the light loose if I hit a big enough bump, but so far it has held on. (I loop the little string around my bars so the light will stay with me even if it falls from the clip.) Runtime is excellent, and it uses a swappable rechargeable battery (the widely available 18650 lithium cells, same as used in Tesla car battery packs and flame-throwing "hoverboards") so if I do run the battery down I can get back to full charge in about a minute and/or keep very warm*. And the price, including the light and clip and one battery and a charger, is less than an extra mount for the Exposure.

It's not a perfect Diablo replacement. My Exposure light can be put into one of nine program modes, which each has two or three intensity settings, while the flashlight has a simple high-medium-low-fastflash-SOS loop. Some current models of Exposure lights have wireless remote switches - great for finding my bike in a huge parking lot, but this light has a simple clicky-button with a rubber cover. The teeth on the clip seem to want to make it point just a little off straight ahead, or maybe it's just my handlebars. There's no helmet mount. While the construction seems solid, I'm a bit skeptical that the manufacturers of this little gem fully appreciate the rough life a bike headlight lives, so I half-expect this light to die after some random bump or fall. At this price I won't be too sad - and I've already purchased a second to use as a flashlight around the house and an emergency backup headlight when this one fails. This light includes O-ring seals that appear adequate for water resistance, but I haven't tested that in anything other than light rain, so I'd at least try spraying it with a hose for a while before heading off on the next "48 HOURS OF TYPHOON CLARABELLE, WE'RE ALL GONNA DIE" ride with Pete Beers.

Summary: this is a good bike light with some great convenience features at an incredible price.

* I'm kidding. The hoverboard fires are mainly due to misuse and abuse. Battery instructions clearly explain that the cells may be hot after use or charging and should be allowed to cool before charging or use. Damaged batteries should be taken out of service immediately, but the hoverboard instructions don't explain how that's supposed to be known or done. The light and charger don't move power fast enough to create the same heating problems, and the batteries aren't kicked around in the light as much as they might be with a hoverboard.

Stravistix for Strava

When I used to use simple cyclometers to see my speed and distance while riding, that seemed to be plenty of data for me. I'd put one on the bars and look at the screen to know everything. It started getting complicated when I added other bikes, with different tire and wheel sizes. I fussed with changing the calibration for a while, which was a hassle. More often than not I simply skipped the whole deal, but I missed keeping an eye on those basic stats.

When switched to a GPS computer that I could move from bike to bike, everything changed. And when I figured out how to get that data into Strava, I gained insight into a lot more information about how I ride.

Now I've added another dimension to that, thanks to Stravistix. This is a browser extension for Chrome and Opera that enhances the standard Strava web page with several convenient features such as expanded map options, quick links to Velo Viewer and RaceShape, and a few options to customize what's shown.

Southeast Boulevard Bike Tour

While DDOT sorts out plans to build more Capitol Hill in the footprint of the former Southeast Freeway, the space has temporarily been restored for use as an east-west connection between 11th St. SE and Barney Circle (Pennsylvania Ave.) SE.

Area overview
It's disappointing to defer this opportunity, though it's unclear how much of a setback the new configuration is. The old freeway was an extension of the busy 295/395/695 complex, but this version has a stoplight at 11th. It looks very similar to the old freeway and even uses some of the original pavement. It doesn't create new livable space, doesn't connect anything to the residential surrounding, but it isn't the same old raceway.

But can bikes use it? Let's see...

Coffeeneuring 2014

Coffeeneuring turns four this year. Not coincidentally, this is the fourth year I've participated in this event. It's not a difficult challenge: ride a bike more than two miles round trip to get coffee (or another seasonal beverage), seven times over a seven week span. Also, document the rides in photos and words.

One change from previous years is that I didn't do it alone. Where in the past I tried to fit these rides between other life events, or occasionally sought company from people who were not attempting the series, this year I rode all seven rides with a single partner. I can attribute this change to several factors, but the biggest is that this year Jean and I have a tandem bike. So, this is a team entry to commemorate our team effort.

The biggest change though is that I (we) actually completed the challenge! The other years I've participated, somewhere between life and other things I either didn't make enough trips or didn't ride far enough - or more regularly, didn't fully document the outing.

Thus I present my first official, complete, and thorough Coffeeneuring report - after the jump.

Mugging, 2006

I chased down a mugger once. I heard a yell from across the street. Looked out and saw two kids pulling a bag from a woman.

I saw them run in two different directions. I jumped into a pair of shoes and rushed outside to follow one at a distance.

Last class

Interesting (meaning far more sucky than necessary) commute in this morning. Glad to see the six plus months of pavement work on the east side of the Capitol has wrapped up and we can make full use of the path. Frustrated that all sorts of temporary barriers are up in strange places in preparation for the 4th of July concert and I probably can't go the way I usually do to get where I usually go.

Completely without surprise to find the DDOT potato wagon pre-staged for the concert and parked in an unregulated area not quite off the Pennsylvania Avenue bike lanes.

Cool bike hunting

Six years ago I made an impulse buy, to give my sentimental favorite beater frankenbike a rest from daily commuting. The new bike was muscular but sleek and sexy, good with a rack and fenders, good stripped down to bare wheels, good in sloppy weather, good on perfect days: it was good.

Cannondale Bad Boy Ultra

But it had a flaw disguised as a feature, a super-proprietary front end that hardly any shop can maintain. This year's cold and snowy weather fully revealed that flaw, and the bike that was meant to carry me wherever I wanted to go whenever I wanted to go there turned into one I dreaded HAVING to ride. Especially on cold days, when a few minutes into every ride the suspension would collapse and the handlebars would drop 3" - more than enough to drastically change the handling. It had to go. I had to get a new bike.
