Seems OK to me in a city setting where there are crowds of people everywhere and you never know what they are going to do especially when their eyes are glued to their phones. One weird thing for me is the national park near where I live that has a series of gravel trails with lots of hills and...
I saw something similar on a rerun of Two and a Half Men. It involved roller skates and a ramp. One teenage boy was in front of the ramp wearing roller skates after stuffing himself with baked beans and the other stood behind him with a butane torch. Didn't work as I recall.
That's just what I use and it works great. I can raise the bike a few inches to a few feet depending on what I'm doing. Got mine on Amazon and think it was about $25.
On my own. Roads and bike trails. Lucky to live just a few miles from a nice section of Acadia National Park that's not on the island. Several nice trails that are barely used even during tourist season. I can often ride those trails and see very few hikers or bikers and sometimes none at all.
Fat tire to me just means a more comfortable ride. The roads where I live are at best just good. No bike lanes. Lots of cracks and potholes and shoulders that are 6" drops in places if a car should force you off. All those things are better navigated with a fat tire with say 20lbs of pressure...
