Commuter bikes

Popular attributes

Around eighteen months ago I replaced my commuter bike and have been bringing it onboard Caltrain and to my office in San Francisco. Since then I’ve kept my eyes out for decent commuter bikes. Popular commuter bike attributes:

  • Inexpensive. Could get stolen or banged around. City streets tend to have poor quality pavement, potholes, etc., and it’s harder to avoid rough road when riding in traffic, so you want sturdy wheels rather than light and delicate wheels.
  • Single speed. Lower maintenance. No need to spend any brain power thinking about gears while focusing on avoiding cars. Note: If you get a single speed and ride it with a freewheel rather than a fixed gear, I recommend two brakes (front and rear) for redundancy in case one fails. Watch out here—some bikes sold as fixies only have a front brake.
  • Internal gearing. Cleaner, lower maintenance, and more reliable than traditional derailleur due to being enclosed and protected from dirt and impacts. If you want to read more the Wikipedia article has a great list of advantages and disadvantages.
  • Belt drive instead of chain. Cleaner and lower maintenance.
  • Chain guard. Keeps your pants from getting dirty.
  • Fenders. Keep your clothes clean when biking through puddles.
  • Weight. Depending on your usage this may or may not matter to you. Lighter bikes are always nice but they generally cost more. I carry my bike up and down a few steps at home, at my office, and getting on and off of the train. That’s a lot of lifting, so for me 20 lbs vs 25 lbs is a huge difference. But if you’re a heavy guy biking from your home garage to a local shopping center with not many hills in between then a few extra pounds on the bike won’t matter much. Also, lighter weight generally means better quality steel and better quality steel generally means a more pleasant ride.


You could of course use any bike. There’s no shortage of great entry level city bikes from the major brands (Trek, Fuji, Specialized, Cannondale, Novara, Scattante, Marin, etc.). But if you’re looking for something with more personality you might want to consider a smaller brand. Here are a few options sorted from least to most expensive. Asterisks next to the brands that are a little more appealing to me.

  • Brilliant Bicycle Co. They’re pretty. One, three, or seven speeds. Frames are made of cheap steel (SAE 1020 aka “hi-ten”) and too heavy for my taste (25.5 lbs and up). $300 and up.
  • State* – Single speed. Choose your preferred handlebar style, seat, and pedals. Frame steel is SAE 4130 (aka chromoly) and a decent weight (22 lbs). A coworker bought one and it seemed to be poorly assembled (guy at the local bike shop said there was no grease in the bottom bracket and maybe a screw somewhere had been cross threaded, but take this with a grain of salt—this is second hand info and it sounded like the guy was very anti mail-order bicycle to begin with). $390 and up. They also have an aluminum single speed and some mountain bikes.
  • Bigshot* – Custom fixies and single speeds. Frame steel is SAE 4130 (aka chromoly) and their bikes nudge into the heavy end of the spectrum (23 to 25 lbs). $400 for a custom build. As low as $300 for one of the pre-chosen builds.
  • Priority Bicycles – Belt drives. Three or eight speeds. Aluminum frame. Casual geometry and handlebars (which isn’t my style, but this is a matter of taste). $400 and up.
  • Wabi Cycles* – Quality steel (Reynolds 725 and Columbus Spirit). A few single speed options. Lighter than many other bikes on this list (the Wabi Lightning single speed is only 17.5 lbs!). Can choose your gear ratio, which is nice if you plan to bike up hills. Classically pretty. $750 and up. My personal favorite on this list. If I had to get another commuter I’d absolutely go with a Wabi Classic, and I’d be heartbroken if it got stolen. I love the understated and elegant style. I get the impression the builder is experienced and cares about the bikes he makes. (Edit: Wabi Cycles changed ownership in May 2015. It gives me a little pause, but as far as I can tell the new owners have kept the same bike lineup and price. As of January 2016 they’d still be my top pick.)
  • Spot Brand Bicycles – Belt drives. A lot of options. Hubs with various numbers of internal gears. Step through and non step through frames. Steel and aluminum. Too expensive for me to choose as a commuter bike but a decent option if gears are important to you. $1,200 and up.
  • Vanhawks – Belt drives. Single or variable speed. Carbon fiber. Lots of technology. Too expensive for me to choose as a commuter bike and the tech doesn’t particularly interest me. $1,550 and up.

The above are just brands I’ve seen with my own eyes. There are many more. Some brands that I’ve stumbled across and know nothing about:

And you can find many more digging through the archives of Momentum Mag.

Edit 2017-03-15: Aventon bikes look decent. Good steel at a reasonable price.

Edit 2017-09-12: VanMoof. Worth a look! The “Standard” has integrated lights powered by a dynamo, an aluminum frame, and gearing options of 1-, 3-, or 8-speeds. Starting at $748. They also have techier bikes, including a e-bike.

Living with a Roomba

Emily and I bought a Roomba after we moved last year. I didn’t want to vacuum or dust mop/Swiffer the whole place on a regular basis. I’ve been mostly happy with the Roomba—I think it saves us time. I think it’s worth the cost as long as it lasts a long time.

It’s quieter than our full upright vacuum and our Chihuahua Toro is less afraid of it, though he still keeps his distance.

We try to be careful to pick things up off the floor before it runs. Phone charger cables, socks, blankets, etc. We also place a blockade line around Toro’s water bowl, ala the Toblerone Line.

It’s scheduled to run once a week. We typically close the doors to our bedrooms to make the coverage area smaller. It usually runs for about an hour before making its way back to the dock. On separate occasions we’ll put it in a bedroom and start it manually.

Our new carpet and rugs shed a lot, which fills up the Roomba’s bin pretty quickly. It has gotten better over the past year, but the bin is still fairly full by the end of a run.

One distinct advantage of the Roomba is that it’s short enough to fit under our couch and another piece of furniture— places that would otherwise never get vacuumed.

Room For Improvement

The biggest downside is that hair gets wrapped around the spinning brushes and needs to be cleaned regularly. I spend about 30 minutes (while watching TV) each month removing the brushes and cutting hair out. It’s not terrible, but it does take away from the time saved by having an automated vacuum. The more expensive Roomba models are supposed to handle this better (we have the cheapest—the 650). Also, I don’t know what would happen if I didn’t clean it. Maybe it’d be fine? I suspect something would eventually break. Or it would clean less efficiently. Or both.

I wish it was smarter about remembering the floor plan and noticing dirt and cleaning dirty areas more thoroughly. For example, our entryway and kitchen tend to have a lot of dirt and it would be great if the Roomba spent more time in those areas. The more expensive Roomba models might be better about this, too.

I think the small spinner brush in the front right side is leaving a horizontal line of scuff marks across our baseboards. Especially when it traps itself in a bathroom. Not surprising, but still unfortunate. It would be better if this brush was made out of a softer material, even if that meant it had to be periodically replaced. I’ve accepted the fact that we’ll have to repaint our baseboards when we eventually move out—not the end of the world.

The Roomba’s suction is weaker than our upright vacuum, but not detrimentally so.

Hiking with Ruby

Today Emily and I hiked 7.7 miles with Ruby at Purisima Creek Redwoods Open Space Preserve. From Skyline Blvd at an elevation of 2,000ft down to Purisima Creek Rd at an elevation of 430ft, and back. You can see info about the hike on Strava. The “Flyby” viewer is cool—you can press the play button and see a replay.

Purisima Creek Redwoods OSP is in the Santa Cruz Mountains between San Mateo and the Pacific Ocean. There are redwood trees, creeks, ferns, lots of valleys, and a few views of the ocean. The trails we took were mostly shaded. It’s a nice place, though the trails do have quite a bit of elevation change.

This was the third hike we’ve done with Ruby. The other two were shorter, at Water Dog Lake Park in Belmont (hike 1, hike 2). Ruby can’t walk yet (come on, Ruby! get with the program!) so I’ve been carrying her on my chest in a Babybjörn. She weighs around 12 pounds and the Babybjörn adds another pound or two. We look like this:

Me and Ruby hiking

She seems pretty happy in there. It’s snug and padded and warm next to my chest. She mostly either sleeps or looks at all the green. We cover her head and arms with a blanket when we’re in the sun.

Today we both wore hiking packs and CamelBaks. I carried our three legged camping stools and we stopped twice to feed Ruby and eat. We did one diaper change… we probably should have done two. With our food water, stools, and baby supplies my pack was around 20 pounds and Emily’s was 10 or 15.

Toro didn’t join us today. Although he does enjoy spending time outdoors with us, the length and steepness of this hike would have been hard for him.

We had a good time and got a great workout.

Great albums, volume 3

One cool thing about scrobbling all music played from my home and work computers is that I have a pretty good record of what music I’ve listened to the most. Here’s a list of some albums that I think are fantastic (continuing a trend from 2005 and 2008).

Adele, 19
Bill Withers, Greatest Hits
Céu, Vagarosa
Florence + the Machine, Lungs
Foster the People, Torches
Madonna, The Immaculate Collection
No Doubt, Tragic Kingdom
Paolo Nutini, These Streets
Ra Ra Riot, The Rhumb Line
Rodrigo y Gabriela, 11:11
The xx, xx

Also I think it’s funny to see a picture of Bach in here:

Blue Apron

I’ve been doing a lot of cooking this week while Emily cares for our new daughter. Blue Apron meals, mostly. Seven of them (we got a little behind while in the hospital).

Blue Apron is a service that once a week sends you a box of ingredients and recipes for three different meals. I find that it takes around two hours on average to chop, cook, put dishes in the dishwasher, and clean the kitchen. Way more time than I’d choose to spend preparing food, but if this is appealing to you then you should totally try it. They do a good job. The food is usually pretty good and it’s an effective way to learn about new ingredients and cooking techniques.

I’ve done more cooking over the past week than at any other point in my life. I blanched things. Used an oven on more than one occasion. Ate goat cheese a few times. Bedlam.

Shiitake Mushroom & Cabbage Dumplings

Spicy Orange Chicken Wings

Broccolini & Goat Cheese Polenta

Fresh Beet Linguine

Dear Government: Please Don’t Muck With Encryption

I was prompted to write this after hearing that the Obama Administration is meeting with the creators of a petition for strong encryption (edit: you can now read the EFF’s thoughts).

Over the past year officials of various governments have expressed a desire to limit encryption or require backdoors to allow government spying (FBI director James Comey, UK Prime Minister David Cameron, US President Barack Obama). This is misguided.

The road to hell is paved with good intentions.

Encrypted communication is hard enough as it is

Considering the number of severe vulnerabilities in SSL/TLS discovered over the past five years I’m surprised https is even still useful. Building encrypted communication software is difficult. Requiring it to be intentionally weakened in specific ways will lead to an increase in unintentional bugs and less secure software.

(This paragraph added eight hours after initial posting:) There’s an underlying question of how feasible it is to add a backdoor to a given encrypted system. When looking at low level encryption protocols it’s potentially impossible. For example, trying to add a backdoor to PGP would fundamentally change PGP. It would no longer be PGP. For a higher level encryption system where encrypted messages transit through an intermediary, perhaps the system could be changed so that messages transit through a government-controlled system, and perhaps the protocol could be changed such that the intermediary decrypts then re-encrypts the message. While these types of changes are feasible, they add complexity to the system. Complexity reduces reliability of the system as a whole and increases the cost of maintenance and initial development.

You can’t stop criminals from using encryption without backdoors

Encryption software without backdoors already exists. Requiring backdoors in a few countries won’t cause this software to stop existing. It won’t prevent cryptographers and software developers in other countries from developing stronger encryption products. Criminals in the US will continue to be able to use strong encryption software regardless of any law preventing it. Making strong encryption illegal reduces the security for those of us with good intentions while acting as only a weak deterrent for those with bad intentions.

Backdoors would be used inappropriately

Regardless of whatever strict requirements are placed upon usage of backdoors, they will be abused. Maybe a hacker will break into a government computer and steal a secret decryption key. Maybe a disgruntled government worker will spy on his boss. The exact scenario is immaterial. Time is infinite, abuse is inevitable.

Therefore it’s not helpful to have a conversation about whether a backdoor will or will not be abused. It is only helpful make the best prediction about how much abuse will happen and decide if this amount is tolerable.

Massive data breaches happen quite frequently. I’ll concede that US intelligence agencies have a decent track record so far (though the Chelsea Manning and Edward Snowden leaks are two titanic counterexamples). I’m not optimistic.

Privacy is a requirement for free speech

The Guardian article mentioned above sums it up well, “the right to privacy runs right in parallel to our right for free expression. If you can’t say something to a friend or family member without the fear the government, your neighbour or your boss will overhear, your free expression is deeply curtailed.”

This argument pertains less to backdoors, where presumably a warrant would be required, and more to banning encryption outright, as David Cameron desired.

Encryption for everyone

Encryption, by the way, is pretty important. Without https and without encrypted Wi-Fi anyone within a few hundred feet of your laptop would be able to see everything you’re doing. Every website you open. The contents of every email you send. How much money is in your bank account. People could capture your login credentials and wire transfer all your money to their own account. Trade stock in your brokerage account. Turn off automatic bill pay for your electricity or mortgage. Buy things with your Amazon account.

Personally I place a high value on my privacy and a low value on the potential of intercepting terrorist communication via a backdoor. The dubious benefits of backdoors do not justify the costs.

17 years and 100,000 miles with an Acura Integra

I’ve had the same car for 17 years. It’s a “Vogue Silver Metallic” 1998 Acura Integra LS, 2 door automatic, and a week ago it crossed the 100,000 mile mark.

17 years and 100,000 miles


I’ve been happy with it. It’s solid, well-made, and has had few problems. Although Acura is Honda’s luxury brand, this car is basic. Not sure what I mean? Here’s an incomplete list of features this car lacks:

  • Automatic on/off for headlights and parking lights
  • Keyless entry (I think it was optional. I added an aftermarket system)
  • Adjustable rate for the intermittent windshield wiper speed
  • Electric seat adjustments (was possibly optional… I don’t remember)
  • No interior dome light
  • Steering wheel stereo controls
  • Outside temperature display
  • Variable valve timing (whether for increased fuel efficiency or increased performance)

Granted it is from ’98 and we’ve come a long way since then.

I still like it. It’s comfortable for me. It’s pretty low to the ground so visibility over other cars isn’t great, but I’m ok with that. The cost of ownership has been fairly low. No chronic problems or mechanical disasters. I get 29 mpg with pure highway driving. Maybe around 25 mpg for city driving.

Biggest problems

Poor automatic transmission

Shifts are rough and slow. The car loses power a bit then mildly lurches forward when moving up through gears while accelerating. It’s been like this as long as I can remember. I don’t know if this is specific to my car or to all Integras. You can partially mitigate the jerkiness by increasingly lifting your foot off the gas pedal as you approach the point where the transmission shifts, then pressing the pedal in as the shift finishes. I think I do this unconsciously now.

Trunk latch

This is a common problem on third generation Integra hatchbacks. There’s a small lever attached to the hatch. You slide it sideways to trigger a solenoid on the car body that releases the lock, then lift to open. Mine stopped working maybe in 2004. Now I must insert the key and turn clockwise with one hand and lift with the other.

A search for “integra trunk actuator” turns up lots of results (a few: hatch lock stuck, G3 Rear Hatch Opening Problem 98+, hatch opener not working, How to Fix an Acura Integra Hatch Actuator, Fixed My Broken Trunk Latch). Some people suggest replacing part 74840-ST7-A01. I tried it but it didn’t fix the problem for me. I think I might have an additional problem where power isn’t reaching my trunk. Possibly due to a blown fuse.

Assorted smaller problems

  • Rear window washer fluid sprayer stopped working years ago.
  • Trunk light doesn’t work (and was fairly ineffective when it did).
  • Radiator cracked and needed to be replaced maybe around 60,000 miles.
  • Antenna stopped going up and down around 96,000 miles.
  • The rubber bits on the outside are deteriorating. Gaskets around the sunroof, windows, between body panels, etc.
  • The paint on the top of the arms that hold the side mirrors has gotten bubbly and chipped off.
  • The engine is fairly weak—basic 1.8 liter Honda inline 4. Either 137 hp or 140 hp, depending on who you ask.
  • The suspension is basic—the ride has certainly never been posh.
  • The heater is slower and doesn’t get as hot as Emily’s 2003 Toyota Corolla. The air conditioning is usually good enough, but is certainly not overpowering.
  • After having disassembled and reassembled various pieces of the interior over the years to replace the stereo or speakers, I’ve noticed that the paneling tends to be made of a harder, more brittle plastic than Emily’s 2003 Toyota Corolla. The plastic feels more likely to break when pried. Whereas the Corolla plastic feels more rubbery and resilient.
  • Not a lot of sound dampening. Ambient road noise tends to be louder than most newer cars.
  • Update 2015-10-14: The little green circle around the “D4” indicator in the instrument cluster stopped working around 100,600 miles.
  • Update 2016-1: The green indicator light on the cruise control master on/off switch stopped working around 101,000 miles.

Quotes, expressions, and mantras

Here’s a collection of quotes, expressions, and mantras that I appreciate. They’re things I respect. Or agree with. Or would make me a better person if I followed more closely.

We need to be the change we wish to see in the world.
Not actually Mahatma Gandhi

The softest pillow is a clear conscience.
–N. R. Narayana Murthy, also maybe Tejomayananda, also maybe an old French or Russian proverb.

A society grows great when old men plant trees whose shade they know they shall never sit in.
–Greek proverb

The best minds of my generation are thinking about how to make people click ads. That sucks.
–Jeff Hammerbacher, “This Tech Bubble Is Different”

In anything at all, perfection is finally attained not when there is no longer anything to add, but when there is no longer anything to take away, when a body has been stripped down to its nakedness.
–Antoine de Saint-Exupery

We who cut mere stones must always be envisioning cathedrals.
–Quarry worker’s creed

To command the wheel of an open car with a girl on the seat beside you was to be established in a condition that only a fool would hasten to end.
–Tobias Wolff, The Night In Question

It is the way of spiritual growth
A man must go forward from where he stands
He can not jump to the absolute
–Bela Fleck and the Flecktones, Sojourn of Arjuna

You could be better than you are.
–Bing Crosby, “Would You Like to Swing on a Star”

Choose your battles.
–no one in particular

Work hard, play hard.
–no one in particular

If you’re not being productive, stop what you’re doing and do something else. If you’re being productive, keep doing what you’re doing.

When making a decision, avoid regrets. If you think you’ll regret something then don’t do it. If you think you’ll regret not doing something, then do it.

Don’t half-ass it. Don’t cut corners.

Don’t put your tools away until you’re done with the job. Also: Always put your tools away when you’re done with the job.

The true measure of a man is not what he accomplishes. It is what he enables others to accomplish. –me, though it wouldn’t surprise me if other people have said this through time
