Disclaimer:
This product was designed and intended for off-road and closed-course use only. Prohibited for use on public streets, sidewalks, bike paths, or other municipal property, unless otherwise posted. Refer to local city, county, state, and federal regulations before riding. Purchasers must be 18 years or older or have parents/guardian permission. Always wear approved safety gear, and ride responsibly.

*Top Speed Information

Off-road Top Speed:

NOTICE: Some vehicles include a “City Mode” that limits top speed to 20 mph, making them compliant with many city and state regulations for use on public roads, bike paths, sidewalks, and parks. Other vehicles may feature an “Off-Road” or “Race” mode, which increases performance and top speed (more than 20mph) but may render the vehicle illegal for use in the city or on public roadways. Vehicles without a “City Mode” and exceed a top speed of 20mph are not for use on public roads, bike paths, sidewalks or in parks, and are intended for off-road, privately owned land or track use only. Always check and follow your local laws and regulations before riding.
