SKI OR RIDE
Wet Paint: Don't allow your front wheel to touch the red handrail at the end of the track
Get to the end of the red handrail, making sure you wheelie all the way and your front wheel doesn't touch down.
Should your front wheel make contact the handrail at any point, hit Return to Last Checkpoint and give it another go - you can try as many times as necessary.
Dizzy Heights: Perform at least 4 flips from a single jump
Instead of jumping the final gap, drop onto the chimney below and it will explode, launching you into the air.
Hold back or forward on the left stick to get your rider flipping, and the Challenge notification should appear shortly after.
Making Waves: Cannonball into the water from the highest peak
Bailout after jumping from this sunlit peak, then hold the left trigger to roll yourself into a cannonball.
While continuing to hold the trigger, push right on the stick to keep falling forwards towards the water - as long as you hold the position it doesn't matter if you bounce off the track as you fall.
The Challenge notification should pop up as you land in the water - if it doesn't, hit Return to Last Checkpoint and give it another go.
Fragile. Be Careful: Do not break the golden pillar!
After jumping over this peak, build up as much speed as you can on your approach.
When you hit the next platform, lean back and try to bounce yourself over the end cap of the golden pillar.
If you get lucky, you'll bounce off the track and sail over the end of the pillar without dislodging it. Unfortunately, if you do break it you have to restart the course to reset it.
Path to Enlightenment: Find the secret pathway
Ride up the base of the initial ramp, but don't clear it. Instead, allow yourself to roll backwards and free-wheel off the end of the starting platform - if you manually reverse you can't get enough speed to hit the rising air current hidden off-screen.
This air current launches you upwards onto a hidden track, which doesn't have checkpoints so you need a faultless run to reach the end.
Drop into the portal at the end of the hidden track to complete the Challenge. If you crash at any point then simply use the same technique to return to the upper track.
Demolitions Side Job: Trigger the switches to collapse the tower
Drop slowly off this ramp at the top of the tower to land on the ledge below.
Once safely on the ledge, reverse into the switch to trigger it.
Further down the course, stop after clearing the fence with the 'No Bikes' sign.
Back up to the other side of the fence to trigger the second switch, then finish the course to complete the Challenge.
Human Flag: Take a rest on the tip of the flag pole
Bailout when you reach the ramp over the street at the end of the track, then steer your rider towards the end of the flag pole opposite.
Hold down Y/Triangle to grab the end of the flag pole when you reach it. If the notification doesn't appear, hit Return to Last Checkpoint and have another go.
Unnatural Disaster: Use explosives to create a tremor
Reverse at the start of the track and pick up the explosive backpack.
Proceed quickly down the course and drop off the end of the ramp with a blue parking 'P' sign at the base, then wait for the explosives to detonate.
Dizzier Heights: Perform and safely land at least 7 flips from the opening launch
As soon as the level starts, hold left on the stick to continue doing backflips. Count 7 flips and push right on the stick to level out as you reach the last spin.
Coasterphobia: Perform a zero fault run without riding the loop
Slow down as you jump off the ramp that would normally take you to the loop, so that you just clear the rail in front of you and drop down. You can't make contact with the loop, so landing inside it then reversing back out isn't an option.
Once you land on the track below, try to build as much speed as you can then bunny hop off the end to launch yourself at the next section above you - if you crash here you'll need to reset the track and try again.
Welcome to Warp Zone 1!: Find and complete the warp zone!
Slightly reduce your speed as you launch from the loop approach ramp, so you instead fall just below the loop to a hidden section of track.
Drive along this short section to enter the warp portal that materialises.
Now you have to clear this tricky obstacle course, reaching the warp portal at the far end to complete the Challenge.
