A Bob can gain speed, but can't gain as much as he loses. You can only gain the amount that you can sprint. Anything above will be lost.

You can go from the speed of a car to a rock in less than a second. If you wan't to stop this from happening, you need to conserve the momentum you had and slow down this process as much as you can.

First we need to learn about the two types of bunny hopping.

Bhop 1 (the space bar): Bhopping with a space bar DOES make you go faster than a sprint, however is very bad for jumping consistently and for reaching speeds beyond a sprint.

Bhop 2 (the scroll wheel): Bhopping with a scroll wheel actually makes you go SLOWER. BUT, it conserves momentum making it perfect for going faster.



How to go vroom vroom zoom zoom: So we know how to conserve momentum, but how do we gain it? Well I've got the answer.
Vehicles.
Get on a car (one that goes fast) and when it goes fast, jump off with the scroll wheel and keep it moving.

The law is as follows:
When going fast, it's not about how fast you're going, it's about how long you've been going fast. You need to conserve your momentum to go fast.

The new official term for doing this is Boost Hopping.
