I haven't faced many ramps yet. The tallest one I've been on was 2 - 3 foot tall. I made it about 75% of the way up, then had to put my feet down and help push. Lynn Ellen says the hill up to the church near her house is a bit steeper at first and then is fairly gentle so she just leaned forward and off she went.
Ramps going into stores have been easy to handle. I have not yet tried mine on a handicap ramp that takes the place of stairs.
Tips for Getting Up a Ramp or Incline
1) Get a good running start.
2) Approach the incline straight on, not from the side.
3) Lean forward. It changes your center of gravity and helps you go forward.
4) If you have to, put your feet down and help propel yourself up.
5) If all else fails, get off and walk your TravelScoot the short distance up the incline.
6) If this is a continual problem, there is an alternate motor that has 11 teeth instead of 13. This motor has its drawbacks though, so it might not be right for you. It cuts down on the total distance you can go on one battery charge, and it lessens your top speed. It's also harder on the belt. You did buy spare belts for an emergency, right? I'd rather just walk my scoot up the occasional steep ramp if I need to. And as far as I know, the 11 teeth motor hasn't been tested by a supersize person.
Added note: Empress Bee says that Sarge has one of the lower teeth motors and he wished he didn't. "He had to change the belt on our cruise this past week. my scooter has the other one and the belt is much older than his and still going strong. but we both love our scooters. so many people want them on the ships!"
