Arctic 2 levels 4 and 6

Answer from: DPdaGreat
I can only 2 star level 4 but I just got level 6. Go fast right away and lean back, then lean forward off your back tire going into the first jump so you land going down the hill, don't let your front tire hit the jump (kinda hard). The rest is straight forward and just hauling ass. Best of luck!

Finally got level 4 three stared! I was using the ninja bike which feels faster but I don't think it is. I spent hours on this level so don't expect to get it your first try.

So try to keep back tire against wall the whole time getting through first loop part. When you drop down try to keep front tire as the only thing touching(I think it's faster), fall down to next part and lean back and slow up a bit for the jump. Try to land without touching the top to keep your momentum going forward. Go slow for the next jump and squeeze in between the two jumps above you. Roll back a little ways, enough to clear the next jump, and gun it to the finish line!

Hope this helps! This was the last level I had to three star and by far the hardest for me. I saw the youtube video for help, even though the kid couldn't even do it.

I have the same problem with 4 and man is it hard! But maybe I can help in 2. You slowly go on onto you fall down the hill. Ride full speed and do the same thing until you get to the point. Hope it helps.

On level 6 I used the acrobatic bike and I skipped all three of the loops. Land at the very top of the ramp at the beginning, lean back and quickly foreword when you get to the end of the ramp, this launched me high enough that I landed on top of the first loop that you get to, it's easy from there.
