You'll find, if you look upthread, that I said adoption will be slow, not rapid. But they will be adopted. That you're seeing them in noticeable numbers is quite promising, and consistent with what I've been saying.

Consider the first iPod. It took almost two years before Apple sold 1 million units. Within two more years, Apple were selling millions of units per quarter. It took consumers awhile to realize that they wanted one. The first iPhone sold four times as many units in its second quarter than its first. Similarly, Amazon started with the expectation of losing money for several years. They knew that it would take a long time before people widely adopted online shopping. FedEx, ESPN, and Tesla Motors all existed for quite a while before they became profitable. Sometimes a product has to be available for some time before demand even justifies its existence.

Expanding bicycle modal share is the same. We would expect the Dutch bikes to primarily sell to new commuters who are willing to buy a new bike. That's not a very large group, but it is only the proportion of that subset that interests us in terms of the success of the adoption of Dutch style city bikes in Portland. That you're seeing them on the roads is a very positive sign. After those bikes have been easily accessible for ten years, and you're still just seeing a few, then one might argue that the market isn't interested. But as long as Portland continues investing in infrastructure, I doubt that's how it turns out. Adoption will be slow, but I expect you'll see more and more of them on the roads. It'll take time. It involves selling a drastic change in lifestyle.
