WHY S9
Small by Design. Built for First Rides.
S9 keeps speed, size and everyday range intentionally manageable, creating a more approachable
starting point for younger riders and first-time EUC learners.
Made for Short Rides
Up to 7.5 miles of published range fits neighborhood rides, practice sessions and short-distance mobility without the bulk of a long-range EUC.
A More Manageable Pace
Up to 9.3 mph keeps the S9 focused on balance, turning and controlled first rides instead of chasing performance numbers.
Compact by Design
The 10-inch wheel keeps the platform small and responsive for low-speed practice, tight spaces and short everyday rides.
