Two wheeled also wins when there’s little space or the track is bad. What’s better really depends on your cycling proficiency, your intended use case and the road network you’ll likely use. And whatever you do, test-ride a few different ones to figure out what works for you. Avoid buying something off the internet without ever trying. (Things are different if you’re buying your second, third,…)

This makes modern 3-wheelers much more agile. They still have certain disadvantages- they’re wide and bulky, you’ll have trouble avoiding potholes etc., but they’re nowhere as bad as those boxes with wheels (tough you can still buy those - their upside is their low price)
And if you have four wheels, people stop considering you a bike.
