I thought CEC was always looking at places for more bike parking (good thing too).
This forum has been amazed on a few occasions at how fast racks have been installed after being suggested by people here.
People generally have been encouraged to just email suggestions to CEC.
Was cycling@, then probably activetravel@.
Perhaps you could set up bikeparking@.
It might be useful to publish a list of ‘sites under consideration’ or better still a map.
Some people might even try using https://edinburgh.cyclescape.org or things like https://www.fixmystreet.com/.
What’s the current bike parking budget and how many racks do you expect to add this year?
Are you still installing Cyclehoops?
