Finally got a Brompton! (second hand)

New Bike Day!

I got this lovely bike (and the bag) from someone local for £500 and I'm over the moon!
I'm moving to a city in a few weeks and being able to take it on buses and trains will be a lifesaver! I've already ordered a rack so I can wheel it around easier, but even then it's light enough for me to carry

Are there any tips or tricks a new Brompton owner should know?
