How fast does 49cc pocket bike go?

Answer 1

If you're talking about the "mini-moto" type miniature motorcycles, they typically will go about 40 - 45 mph, possibly a little faster in some cases. When you're riding one, though, it seems a lot faster!
This depends on what bike you are talking. On average, a 49 cc bike will do about 30-35 mph. But some super preformance bikes like the Honda NSR 50 will easily go over 60 mph. But a cheaper Chinese made pocket bike will only go about 20 mph. It just depends on the bike.
it can go 45 mph but this depends on the sprocket. if it is a 68 tooth sprocket it will go 35mph but if it has a 40 0r lower tooth sprocket it goes faster due to more revolutions per minute
60km per hour
