I'd like to build an electric scooter for persons with mobility issues to assist them to traverse the soft white sand to access the beaches, ocean, get their feet wet :O)
The vehicle must be able to cut the sand AND climb the ADA ramps incline (nominally at 1in rise per 1ft run)
I'm thinking 18" dia, 8" wide rear tires to cut the sand. Maybe all we need is 15" !?!
MAX speed is 6mph (speed is not a factor here)
Passenger weight is 220lb with cargo weight of <= 30lb
I'm thinking torque over speed.
My question is, is what size motor/controller do I need to use in this build? And can I be supplied with same?
