"Big Boy" distance
I'm not able to get more than 3 miles on the board with a full charge. I weigh around 260 on the board with my stuff. Is anyone else getting better results?
Not looking to offend, but you are at the top end of the weight limit for this board, so it makes sense that you would be getting less mileage than people 50-75lbs lighter than you. The only thing I can think of to do would be to inflate the tire to a higher PSI (but not higher than the top end recommendation), as that definitely helps with mileage, although it is not as smooth of a ride.
I'm 6ft 1" 230 and I got right around 5 miles. I guess it also depends on the terrain you're riding on. I'm not sure what my psi is though.
It been too long since physics class, but these are the equations for an inverted pendulum energy system - https://en.wikipedia.org/wiki/Inverted_pendulum
We talk often about mass in the forum, but other important thing is height or more specifically the height of the center of mass. Adding a backpack, for example, can increase your mass and the height of the center of mass.
Then there is also PSI that folks have pointed out, which contributes to rolling friction, so the board works harder to overcome friction as it tries to balance you. And rolling friction is also a function of mass, so you're losing again!
But all of this depends on square of velocity, so going a bit slower should have the most dramatic impact.
In short, going a bit slower is a good place to start. I'd also try PSI and figure out a way to load your backpack in a way that keeps the weight as close to the ground as possible...
Please let us know what you find. I need to experiment a bit too, but I never have my iOS device around to measure battery levels properly.
