I dont use my board as some perhaps, for instance I dont do it for companionship, I dont do it for thrills. I dont do it rain or shine. But I use my board for transpo. At 15mph, that is five to six times the speed of walking. Indeed, I have to slow myself to be safe often. I use the sidewalk extensively. At fifteen, it is slow enough to maneuver out of most dangers, and if you actually do crash, it is just scuffed fabric.
When I get over twenty, it is just one mistake or missed thingie away from tragedy. In addition, I negate much of the wind resistance. I negate much of the heat problems. I negate much of the battery problems.
It allows me a wide range of battery configs that would work.
Everything bad happens after 20, and that includes physically.
I was thinking about this as I went up and down various stuff, and would shift my weight as an EMERGENCY, and have plenty of time to shift weight and not upset stance. Had I been at say thirty, I dont have much time.
I can keep my bushings cruising tight for agility.
It takes a whole nuther world of concerns, to build a 35+mph board, and that adds up.
I am making the case, that it only has to shuttle you at 30 max, to be considered as fast as is safe. That is just an opinion, but it also makes us as a group less dangerous.
Not trying to stop anyone building a fast board, just asking if you REALLLLLLLLLLLLLLLY need faster than 30 often.
