New Way to Ride – Unique side-by-side decks with full grip tapes provide a new way to ride an electric scooter with your feet side-by-side. Rear-Wheel Drive for Stability – Rear-wheel drive apportions greater weight to the rear, enhancing both drive traction and ease of steering. High Torque and Top Speed – Powered by Razor’s Power Core high-torque, maintenance-free, hub-driven motor that generates speeds up to 10 mph (16 km/h). Easy to Ride – Side-by-side foot placement, a thumb-activated throttle, and a hand-controlled brake make the Power Core E90 Sprint an easy, rider-friendly option for both beginners and experienced riders.
