I cycle to work every day from hackney to barbican, takes between 20 and 30 minutes depending on traffic and my energy levels.
East London is good for cycle lanes, and eventhough you have to share them with black cabs and buses, they're pretty safe.
In recent years I've noticed a massive increase of hipster cyclists on their fixed wheel pieces of crap.
Some of these guys have better handlebars on the faces
I probably have to tell off a cyclist a few times a week these days just because they don't have a clue how to ride safely.
Plus we live in a world of selfish pricks who spend more time looking at themselves or their phones than at other road users, or the fucking road.
