» In Copenhagen the bicycle is king, with 40% of journeys to work/education undertaken by bike. Most bike lanes are segregated (it helps that main streets are broad) and can get very busy in the rush hour. Copenhageners own five times as many bikes as cars. This may be why they rarely seem to lock them up.
» Electric scooters are now commonplace (but aren't always left in the most sensible locations after people have finished riding them).
» Uber withdrew from Copenhagen in 2017 after a change in Danish law.
» The CopenhagenMetro has two lines, opened between 2002 and 2007 and operational 24 hours a day. Both are driverless. M1 goes to the new town of Ørestad and M2 goes to the airport. You could ride the whole network in an hour.
» Two new lines were due to open this month but, in familiar scenes, have been delayed until later in the year. Building sites around the city attest to this. M3 will be an inner suburbanloop, and M4 initially just the busiest inner city section.
» I rode the Metro twice, once from the airport and once to the airport. It's swish and futuristic. Descent into the under-ground stations is via escalators suspended above the centre of the platforms.
» There's also a suburban S-train network and a regional rail network. I did not ride these.
» Copenhagen also has a bus network. I did not catch one.
» A City Pass covers public transport across inner Copenhagen. It costs £10 for 24 hours, £18 for 48 hours and £25 for 72 hours. We walked everywhere, so it wasn't worth buying.
» A Copenhagen Card covers public transport across Greater Copenhagen and entrance to numerous tourist attractions. It costs £48 for 24 hours, £72 for 48 hours and £90 for 72 hours. We're glad we didn't waste money by buying one.
