I saw it in the shop and it moves slow and has a lot of torque the little motor rotors really grip the tires hard.
I bet it would climb and descend a slope okay. Maybe not a mountain but putting it in a driveway, oh yes it would.
The shop here is working a better front wheel setup to run it off the pavement. I think just having a couple pieces of plywood to run the front wheel on would go far.
