Like most facets of society still lingering from the industrial revolution, the 8-hour work day (or 5-day work) week makes no sense. Why? The 8-hour work day causes deadweight loss.

The iPhone 6 and 6 Plus have done a much better job of capturing a broader audience for Apple than previous iPhones. The 6 and 6 Plus together drove a massive increase in Q1 revenue for Apple: 33% over the same time last year.

But these phones are not iPhones so much as they are phones that runs iOS.

In January I told the story of Ryde, the perfect ride tracking app for urban bikers, and why I decided to kill the project. I shared the post on Reddit r/bicycling and the response was overwhelming. That week had record traffic on the Modeo blog. Comments and PMs piled up with people saying how disappointed they were that I killed the project.

Well Ryde is back...

The iTroll is a custom single speed Surly Troll with a BionX electric assist motor. It's also the only bike I own that can connect to the internet. It is my custom built prototype of the future of electric bikes.

An e-bike, or an electric bike, is a bike with a motor and a battery that make biking easy and accessible for a wider audience.

Here are the basic characteristics of an electric bike:

Ever argued with somebody that hates people who bike? Here are all the retorts I've come up with on my ride home (and not in the moment).

Ryde started in the winter of 2013. I had a good job. I made video games. I got paid way too much. But I was bored. I needed a challenge to keep me occupied and game design didn't have one for me.

Hot Cross Buns (Buns for short) is a 2012 Felt Breed purchased at Huckleberry Bikes in downtown San Francisco. It's a stiff and reliable single speed cyclocross bike to which I've added a few mods for the North American Transportation Biker.

The Superflash tail light by Planet Bike has been my go-to rear bike light for many years now. There are several models starting at just over $20.

Here's why I like 'em.

Yes, I ride a bike. Yes, I live in San Francisco. Yes, there are hills. No, my bike does not have gears. Here's why.

I don't know about you, but the best way for me to shave seconds off my commute is to push the snooze button less.

Here are 5 reasons transportation bikers benefit from riding a light bike.

When I'm designing a product there's a phrase I use when my product kills somebody: bad user experience. Design means identifying bad user experiences (preferably before people die) and implementing solutions. When those solutions are simple and low risk they're called "low hanging fruit".

I've planned many of my own group rides. I am currently in the process of designing the route for the SF Tweed Ride next weekend.

Here are 10 rules for designing a great group ride:

Drop bars are a handlebar style found mainly on road, 'cross, and touring bikes. These bikes are frequently sold on their "versatility". Not only will they get you around in the city, but you can also ride recreationally to mystical faraway lands inaccessible on a hybrid or single speed bike.

But the fact is that drop bars, on most bikes, cause us to make big sacrifices in safety.

123D Design is an amazing tool for creating custom 3D models. It's totally free, runs on basically anything, and is incredibly simple. 

But the .123DX file is basically useless outside of 123D Design. This makes it very difficult to jump from prototype to product within the 123D ecosystem.

Fear not! This is how you extract a .SAT file from your .123DX file.

A recent article published by The Washington Post is attempting to answer the question "why don't Millennials want cars?" 

While I can't make generalizations about the trend, I am one of those Millennials who gave up a comfortable life in the suburbs to live on the fringes of society as a bike-riding-urbanist-techno-rebel (ie. hipster).

A transportation biker is somebody who bikes primarily to get from point A to point B rather than in large loops designed to induce suffering.

Every Sunday approximately 1.5 miles of JFK Drive in San Francisco's Golden Gate Park is closed to cars. You will frequently find me biking this stretch of road and blasting "No Cars Go" by Arcade Fire on my UE Boom. It's a powerful, orchestral song with few words but a lot to say.
