The Slider's totally unique  propulsion and unmatched maneuverability by way of the rear articulating wheels is one of the reasons that it is at greater risk of being damaged if the unit is over-loaded with the wheels turned. Although the U6 was statically loaded to over 600 lbs. and rigorously tested by 250 lb. riders without failure, this doesn't mean that it can be ridden down stairs or off curbs by even a 200 lb. rider as this induces an enormous amount of "g" shock loading that over time will likely damage the wheel assemblies or frame.

If we condone or warantee the units against jumping, What's the limit? > curb? > 1' ramp? > 3' ramp? > flight of stairs? > ??
