The most reliable method to decode / pick / crack most bike locks is the "Indirect" method. It may not be the fastest method, but it's the most reliable one. It even works on some that have false gates.

Method:::
With this method, it's important to have constant strong tension while testing the wheels.
First of all, put all the numbers to zero on each wheel.
We will start with the wheel on the right (when numbers are oriented the correct way).
Let's call that wheel number 5 (ie wheel5).
Tension the lock while at the same time turning wheel4 back and forward. Take note of how tough it is to turn. Make sure to put wheel4 back to zero.
Turn wheel5 to the number 1.
Now tension the lock again while at the same time turning wheel4 back & forward. Take note of how tough it is to turn.
Then turn wheel5 to the number 2.
Test wheel4 again...
Do this until you've tested all the numbers on wheel5 (from 0 to 9) and take note which number on wheel5 makes wheel4 tough to turn. That is the correct number on wheel5. Leave wheel5 on that number.
Then repeat the process but leave wheel5 alone (leave it on its correct number). This time we turn wheel4 from 0 to 9, testing each time on wheel3.
The number on wheel4 that makes wheel3 toughest to turn is the correct number for wheel4.
Do the same for each wheel until you've got the correct numbers for wheel5, 4, 3 and 2.
Now turn wheel 1 all the way around while tensioning the lock until it opens.
When I say "tension", I mean pull the lock at both ends as if you're trying to pull it open.
