That would rather depend on which city and where in the city you were riding it.
About 30 to 35
they go aproxxamately 50-60k/h
49cc. 49cc. 49cc. 49cc.
yes there are.
49cc to 110cc
yes
20-30mph
Yea
Why is the charger controller on a 49cc change from a four wire to a three wire?
The 110cc. engine will make the bike go about twice as fast as the 49cc. bike. If you can't figure that out than you shouldn't be riding a pocket bike Piston size. a 110cc will be massive vs. a 49cc. block sizes are also a good way to judge. Google it for actual sizes.
how do you make pocket bike turbo or where do you buy it i need it for my f4-15 pocket bike 49cc
