So, another thing we discovered in Amsterdam were these particular types of bicycle racks, which were probably the most common type we saw there. In residential areas, these were on every street corner, and they were also common around shops and grocery stores.
Basically, you put your front wheel in the little scoop, and then lock your bike to the pipe next to it.
Here is why these are wonderful, and why Portland should start installing them en masse
Putting your tire in the scoop holds your bike up for you, so you can load and unload your bike without having to hold it up or worry about it falling over.
The scoops are at varying heights, so the two bicycles next to each other don't get all tangled up between handlebars and whatnot.
You can fit bikes a bit closer together than on the standard "staple" racks, without getting the bikes tangled up together.
We found these to be very convenient and practical, and would love to see some show up in Portland. Maybe Portland should start a pilot program to install bike parking in residential areas (so that residents don't have to leave their bikes in their living rooms, and so visitors coming by bike would have a place to park), and can pilot these bike racks, to see how they work out? :) I, for one, would love one just outside our apartment :)
