Experience acceleration like never before with the Segway-Ninebot Gokart PRO. With a top speed of 23 mph and a 15.5 mile range on a single charge, it outperforms 150cc gas-powered go-karts on the track. The frame is manufactured using high-strength steel, carrying a payload up to 220 lbs. and both the frame and steering wheel are adjustable to accommodate riders between 4’5” to 6’3. Drift like a PRO! The cutting-edge TPE rear tires bring the most exciting drifting experience, EVER. Teamed with the controllable rear-end and high-speed corning, you’ll drift like a professional racer. The high-wrap racing bucket seat supports the driver and resists centrifugal force when turning. Designed with the rear engine close to the drive shaft, achieves faster acceleration. Four 8W high-power speakers simulate engine sounds of single-cylinder, two-cylinder, V8, or V12 engines for a more immersive experience and can then be used as a Bluetooth speaker to play your favorite tunes. The Ninebot Gokart PRO has definitely UPPED THE GAME!
