Step Two: Assemble the front wheel
1.Loosen axle nuts on front wheel to make room for the front fork.
2.Lift the front of the bike and lower the fork onto the wheel axle.
Notice: The brake rotor should go into the brake caliper in between the
brake pads and the axle should enter the fork dropouts fully. The front
rotor orientation should be to the left of the fork.
3. After inserting the front axle onto the fork, you will need to line up the
axle lock washers (these are the metal washers,put thin one on the
inside,thick one on the outside) with the hole at each fork.
