More and smaller sites are better than fewer mega-docks, in my opinion.
(I'm guessing that maybe the Dalmeny Street dock has been resited from Foot of the Walk in this case (here was me hoping they had started to buy new ones and so the other sites might also start to be being upgraded soon)? If usage shows demand for more, an additional dock in the Kirkgate shopping centre square (eg, outside Lidl) might be a better addition.)
I'd much rather have 8 bikes every 5 - 7 minutes' walk apart, instead of less convenient mega-docks further away (which also require much more space to install them). If you have to walk too far to get to or from a dock, the bus starts to look a more tempting option.
There are also really ridiculously long and double-sided docks such as Bristo Square which are so long that invariably the bike it decides to release is on the opposite side to where you are standing and involves a "short" walk around the wall of docks just to get to it!
It would be better to have 4 docks of 10 bikes in various locations (why not some directly outside Teviot House itself, for example) than one huge dock that is a bit of an obstacle in itself. At the very least, huge double-sided docks should be split into multiple parts so that you can more easily walk on through the other side.
