BIGGUP THE BIKE HANGARS! I am 100% behind the on-street bike parking hangers. Great debate over recent pages. (Amazingly, I 'liked' about 5
teuchter posts in a row

)
I think the real issue is whether we want a "liveable" city - one where people can choose to travel around under their own steam (walking, cycling) in a pleasant environment, rather than one which is dominated by noisy, polluting motor vehicles. Lambeth has one of the most polluted streets in the UK (Brixton Road) - we need to change this.
We need to get more people cycling.
The bike hangars aren't a sop to middle class bike users who find it hard to store their £2,000 Pinarello. They are an important signal that bicycle transport is as valued as motor transport (which entirely dominates our city) - as well as a neat and practical solution for the many of us who live in cramped, converted flats, and struggle to store 5 bikes in a tiny hallway.
However, the bike hangars aren't enough - and Lambeth aren't going nearly as far enough with their cycling strategy. We will only truly get mass cycling in London if we build safe infrastructure that encourages people to cycle who do not do so currently. The roads need to be safe enough for your 8 year old kid or your 80 year old granny to ride on. This is why we need thing like
proper, segregated cycle superhighways.
High quality, safe cycling infrastructure will get more and more Londoners cycling and our city will benefit hugely as a result.
And then people will be crying out for more bike hangars on the street.
