This is a guide on some of the tips and tricks you can use to help you get through that difficult track!
Key:
(>) = Right Key
(v) = down key
(<) = left key
(^) = up key

As we all know, Riding on freerider tracks can be kind of hard, especially with the sharp turns, long jumps, and Far-down-falls. Or with a badly-made track. The following tips could prove useful when on one of the above.
Holding the (>) when speeding in a downwards slant can help stop you from doing an accidental wheelie and falling off the bike.
In the event of the above not working, when in a wheelie about to fall backwards, hit the (v) to jump forwards. Don't hold it too long, or you'll fall forwards, And I still haven't figured out the tricks of stopping that!

When in the event of something like:Pull the (<) for a small height boost, and then do a frontflip (hold (>)) as your back tire reaches the bombs helps.
Doing a backflip can help for things such as: That you don't need much height, but enough to get you over.

If you're going up a steep ramp that a backflip won't get you over, always try just holding (>) the whole ramp!

When trying to go up a steep ramp, To avoid crashing, hit the (>) to push forwards to avoid falling backwards

Going up stairs; It can be a hard task, especially with the BMX. So, Get a speedy start and pull back just as you hit the stairs so glide up it like a ramp.
Speed is always a big help in getting across a long jump. Press Z and go back some, Press Z again and floor it!
