A thread

I got back from the farmers market yesterday to find that my trailer attachment was being held on by 4 metal threads. The braided wire I had used stretched out, and once it got long enough the PVC tubing was able to rub right through it. It chewed through 4/5 wires completely, and then ate through most of the remaining one.

Back to the drawing board for this design!

So you suck at mountain biking...

Well its not so bad. But my first foray into mountain biking was not the most graceful thing I have ever done. I crashed a lot. I hit a tree with my handle bars, I lost control on a turn and landed sideways in the bushes, I did a big crash after I lost control on a sand bar that almost sent me rolling all the way down buck hill, and skidded out on another corner. But I did get this cool picture of me looking determined!

Worst of all though, I got a dreaded DNF (did not finish) when it was just too much. I was too banged up, and too tired to properly control the bike and I figured I could either end now or end in a crash some place else. So I rolled off. It also turned out my front tire was flat, but we didn't see that until we got home.

So, here is looking towards the Cyclocross season which starts in September when I will have the chance redeem myself as a competitive bike rider!

To market

To the farmers market, on the bike, with a bike trailer. That earns me some pinko Amsterdam points for sure.

With a load the trailer still rides great. You have to get used to the odd things it does to momentum, like when you are cruising on flat you just keep going, but going up hills is much harder. Object in motion, gravity, and all of that. But I can still speed if I need to, and it doesn't affect the handling of the bike otherwise.

Trailer part 2

My test trip with the trailer taught me a few things, that I corrected today. The wheels couldn't come off, the bolts that hold the wheel attachment on still get stuck on doors and corners, and there was also no spot to attach bungees. I solved the first problem with a long piece of scrap copper that I cut and screwed into the frame, and then ground down the screw heads so they were flush. I then took a radial sander to the copper to smooth it out, and ended up sanding the entire frame! It looks better than new now, and I coated it with spray sealer to keep it that way. I removed some wood from by the wheels and now there is space for them to come off, and I drilled some holes in the bed to attach my bungees.

The whole thing rolls great! The connector is smooth and can bend more than the bike can turn. I am looking forward to a nice big grocery run.

Bike Trailer

I was walking Winnie and over behind the security alarm building, and there is this little section of scrub that people just dump their typical urban junk in. There is a refrigerator, a car tire, a shopping cart, and a few days ago there was a torn up InStep Quick-n-Lite bike trailer. The same kind we bought last summer for winnie, which was fun but she kind of hated it. So I dragged the trashed one home, sold Winnie's for $40 (same price as we bought it) on craigslist, and started to convert the busted one to a bike trailer by ripping off all the fabric and coverage parts.

It was missing its bike attachment part, so I towed it to work by wrapping the end with an old bike inner-tube and attaching that to the back which was good enough (barley, and it somehow managed to flip completely over at one point). Then I took off the wheel attachments and inverted them so the wheels would be inside the frame, which makes the entire thing more narrow and easier to maneuver. Also this way, the wheels are protected should the trailer strike anything. I then cut down some aluminum rods to lay down down the center so it can support weight. These I attached with bolts. To make the connector, I used a quick release attachment normally used for pressurized air, that just happened to screw into the soft aluminum at the end of the connector arm. The piece on the bike is a small drilled steel plate, with an eye-hook bolted onto it, that is attached to a piece of PCV pipe with steel rope, that is attached to the quick connector. I might have to re-do this part, because it is kind of huge! But it works great, so I can't complain.

And here is the finished product! Now I have to figure out how to attach a load on it, like groceries, and also figure out what to use it for! I also have to make the clearance between the wheels and the trailer bed wider, so I can remove the wheels.

Megan's KHS 500

Here is Megan's new toy, a KHS 500 road bike! Carbon fork and chain stay, aluminum all the rest. Megan has outgrown her old bike, which will be used as it has been as a comfortable commuter hybrid with fenders, rack, and basket. But, all that weighs almost 40 lbs (with out a backback!) while this one comes in at just above 20. Plus all the benefits of road tires, shifters and brakes. Also known as... much faster!

We took it out to the fair grounds so Megan could get a handle on the very different feel of this bike. It really is like the difference between the Volvo and the Scooby. Everything gives you a much faster response from turning to braking to shifting to accelerating. Perhaps a little less comfortable to ride though! But after a short time riding around, Megan was riding confidently and speedily. I got this photo as we were zooming down a small hill.

Last night we went over to the family bike shop and the bike got a full work over. We added an "interrupter" brake on the handle bars (like my bike) so you can ride upright and still have the rear brake available. It also got a new stem installed so the handlebars are a little closer, and it is better looking too. Today we stopped at freewheel to use our coupon and get Megan a new and much better helmet (not pictured), water bottle cage, saddle pouch, and extra inner tubes. So she is set for a summer of riding!

On our way home on the transit road, Megan kicked it into her highest gear, which is at a ratio that my bike can't reach. I had to spin fast to just keep up! See you out on the trails...

Lit up






















I attended a bike safety/community dinner at Macalester last night, and listened to one talk on commuting safety and and another about the Sibley Bike Depot. The talks were good and the people where nice. They were selling deeply discounted lights and locks, so I picked up a set of lights and a new U-lock. So I am all lit up with 2 reds in the back and 2 whites in the front. Although now that I see a little bit how great it is to have lights that show me where I am going instead of just show cars where I am, I am looking at the MiNewt from NightRider. More of a headlight for a bike than anything else! Now all I need to do is install heated seats and a radio and I will match the Volvo soon!

Bike Snob Zen

One of my new favorite blogs is Bike Snob NYC. It is a mix of bike humor and observation, irony, and a study of NYC hipster bikers on their fixies. Each post is so cross linked to other posts that it can take a long time to get through one. His writing cracks me up. For example,
If you're unfamiliar with the recumbent, it's similar to the bicycle in that it has two wheels and it's human-powered, but it's also very different in that you kind of lie down on it. Also, it replaces the saddle with a lounge chair and your dignity with a big gaping hole.
But, besides bike hilarity he has some great things to say, like this from yesterday called, "The Indignity of Commuting by Bicycle: Weirdness"
I too long for something, and that is a world without stupid behavior. And recently, I made an important discovery, which is that while you can't change the world you can change your own perception of it. Certainly I can't eradicate stupidity from the Earth (if only because that would also involve eradicating myself), but I can keep myself from getting angry about that stupidity. This realization in turn brought me to a revelation: Stupidity minus Anger equals Weirdness. In other words, when I observe something inexplicable and get angry about it, I've observed something stupid. But when I observe something inexplicable and don't get angry, I've simply observed something weird. And weirdness is much easier to live with than stupidity.
And here is the snob on Cyclocross which he is a fan of:
But let's be honest--part of the bicycle's appeal is its swift mobility. What cyclist hasn't fantasized about living in some kind of Apocalyptic wasteland with only his bicycle and his wits to keep him alive? Who wouldn't want to live in some sort of real-life "Red Dawn" and carry out guerilla attacks on bicycles under Patrick Swayze's capable leadership? Well, probably very few people, and I suppose that's why cyclocross is still not that popular.
So, keep racing cyclocross on your recumbent bike in preparation for the red dawn but don't let stupid things make you angry, they are just weird after all.

And today's bike of zen. It is an 8 speed/single speed cyclocross bike - aka you can shift 8 times but the ratio remains the same. What class would you enter this in I wonder?

Happy Birthday ... to me!

Great birthday week/weekend! Dinner out with siblings, music, drinks, and friends visiting this weekend.

But to follow up with my last post, this is my birthday present to myself! It is a KHS CX200 Cyclocross bike that I intend to race on this coming fall. Aluminum frame, carbon fork, and STI shifters. Along with that, Megan got me clip-less shoes, and T&L got the pedals to go along with it. So I will be clipped in and ready to go! Races start in late September and go to November. L. has been racing Cyclocross for years, so I will be in good company.

What is Cyclocross? Wikipedia says: "
Races take place typically in the autumn and winter, and consists of many laps of a short (2.5–3.5 km or 1.5–2 mile) course featuring pavement, wooded trails, grass, steep hills and obstacles requiring the rider to quickly dismount, carry the bike whilst navigating the obstruction and remount in one motion."
Or as the video said, "a bunch of skinny dorks riding around on road bikes in the dirt." Races are broken into skill categories and that determines how long you ride. In motor sports, my favorite Rally Racing is probably the most comparable. Street cars running really fast in the dirt, mud, snow, and on pavement, compared to road bikes going fast on grass, dirt, mud, and pavement!

A Cyclocross bike is more of a classic road bike frame, so a little larger than a modern road bike, with softer and more grippy tires, and cantilevered brakes. If you swap out the rough tires for skinny road tires, they make perfectly good road bikes too.

Not sure when it gets here, but I can't wait!

How cute is this?

Added Aug 5th: We took about a 12 mile ride and the trailer rolls nice, but slows me down quite a bit! The entire load is about 50 lbs which makes starting and hills harder, and the wind resistance makes cruising slower. Megan and I normally cruse at around 15 mph (says the GPS taped to the handle bars) but I bet this takes it down to 10-11 and I was really pushing the entire time too. 
Winnie did good, but she doesn't like stopping for stop lights or bumps much, and we need to firm up the bottom because it sags down when she is moving around. We put her harness on and attached that to the top cross bar so she couldn't jump out and that works well. She hates it when Megan gets in front of me because she cant see her, and thus she is 'GONE FOREVER' "bark bark bark." But on smooth trails she was all smiles as we zipped along. 
Look for us to ride up soon!
