However, not all bike share is created the same, and Portland's new system has the distinction of being the largest "smart-bike" system in the country. This is in contrast to most large systems which rely on "smart docks" instead.
The primary difference is the location of the electronics. In a smart dock system, everything is handled by the dock and an attached kiosk. On a smart bike system, the bicycle itself carries all the technology. That means you can lock your bicycle to anything. You use a pin code to remove the built in lock and when you're done, you reattach the lock to the bicycle (and another fixed object of course). Built in GPS ensures the company knows where the bike is.
So why pick one system over another? If most cities have used smart docks, why did Portland go with smart bikes?
The biggest factor involves cost and ease of deployment. A smart bike system actually requires zero infrastructure. You can release the bicycles and let users dock wherever they want - existing racks, fences etc. Docking areas can be created virtually, and displayed with signs or stickers.

A smart dock system can't launch until the docking stations are all in place. You trips are limited to starting and ending at a sanctioned dock. And these docks are expensive, heavy, and proprietary. When Boston launched their system, they installed 5 stations a day, the best that could be done with the need to use trucks and a specialized crew. While the stations are solar powered, and thus don't require utility connections, they still require proper installation. That's a lot of time and money.
