A 50cc monkey bike typically has a top speed of around 30 to 40 mph (48 to 64 km/h), depending on factors like the specific model, weight of the rider, and terrain. These bikes are designed for fun and agility rather than high-speed performance. While they can be quick for their size, safety and rider experience are more important than speed.
