I have good ramp in place that was good for her old electric scooter.
This new scooter is supposed to have a 6 percent rise/at 10.5% on the ramp.
How do i calculate my ramp angle to achieve a a 6 percent rise/at 10.5% for my ramp. I may be giving you the wrong terms.
The old scooter is longer and will not tip on the current ramp. This one is shorter and designed to turn sharper in the house. Its length is shorter and will tip on the old ramp.
