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...
