The VMAX Urban Scooter R20 reaches a gradient angle of max. 15 degrees.

This must be a really great device, the world has been waiting for something like this. *Sarcasm off* when you consider that 15 degrees is the equivalent of a 26.79% gradient. The steepest Alpine pass in Switzerland is the Bamberg Pass with 25% gradient and the Weissenstein Pass with 22%. I doubt very much that the device can get up there. Somebody probably didn't pay much attention to geometry and confused degrees with percentages. Anything else would really surprise me. But prove me wrong and teach me better. MFG
