I grew up on a farm as a child and so one of my fondest memories was putting around everywhere on my mini trail bike.  I assembled it together using different parts I could scrounge up.  It was powered by a 5hp lawnmower engine, lol.  Didn’t matter though,  it was an awesome machine as far as I was concerned.  As I was surfing the internet the other day I was surprised to find that you can buy a mini bike for quite cheap, around $400.  I am tempted to buy one just for nostalgic purposes.  Don’t think the wife would go for it though.
