Tips and Tricks
All that matters is getting a ton of coins. Combos give you more as well as stunts that you perform with your driver.
Remember that you have three tries so use them for maximum gain of coins.
Safe landing: after a high jump, tap the left button to bring the bike in a horizontal position, and as soon as you’re about to hit the ground, tap the right button to have some speed. Just make sure your falling speed is not too great, otherwise your bike will break.
If you tap the Jump button (up arrow) twice, Johnny will jump off the bike. You can collect a lot of hard to get coins this way.
Learn to do spins and flips and then, when at the right angle, tap the up arrow quickly for the driver to jump and get that coin you really need.
Invest your money in the first bike that you get and listen to the advice you get before the race (if they say better spin is required, upgrade your spin and so on).
For tracks with short distances, you will need a better acceleration, for longer tracks you will need better top speed and for those zany ones with a lot of jumps, you will need the Spin.
