The last time I figured this out, I found out that bicycle with no training wheels are faster. The comparison of generating speed is this; bicycles allow you just to pedal to generate fast speed, although freestyle scooters allow to step on the ground and push forward. I suggest you use a bicycle if you are entering a racing competition.
No, the freestyle stroke is generally faster than the butterfly stroke in swimming.
a gas scooter it will go faster than an electric.
but a engine in it
They would both be about the same for speed.
improve your balance a lot and strong and faster
55-70mph is top speed of the scooter.
An improved flow of air and fuel mix will make the scooter faster. You can do this with an aftermarket exhaust.
the brake
a car is faster and much safer then a bicycle. your welcome

Go downhill
If all you have is a bicycle you will have to keep on pedaling faster and faster.
