How do you make a bmx lighter?

Answer 1

You start off with a light frame, then you get a light fork, light wheels, light tires, light bars, light seat post, and light cranks.

To get a light bike, you really have to use light parts through and through, and it's cheaper to buy a light bike already to start with than to lighten a heavy bike piece by piece.

Answer 2

One good way to make your bike lighter is to take your rims and drill holes between all of the spokes. Although it does not make a huge difference, it definitely helps.
