I'm in the middle of my 53rd viewing of Frozen (this one, not this one) and it occured to me that the bicycle that makes a cameo during "Do you want to build a snowman" is by far the most modern piece of technology in the movie. While a time is never established for when the film is occuring, but the boats used by royalty are all sailing vessels, even though steam ships predated the modern bike by at least 50 years. Anyway, these are the things you think about when you want the movie repeatedly.*
I tried to find a screenshot of the bike, but I couldn't, but it looks like a standard, modern design.
*Also how much money Arendelle will save in military spending since their queen is now the ultimate military weapon.
Also, I'm on vacation this week.
