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.
