To detach the front wheel, place your hands as shown in the pictures
Gently open the frame just enough to allow the axis of the wheel to come out
If you're about to change the whole wheel, remove the elliptical washers and memorize their L&R position
Mounting back the wheel
Put the elliptical washers back, but be careful about their L&R positions. The thumbs should always be pointing inwards
Insert the wheel into the frame and adjust the washers, so the wheel can lay in its rearmost position
Put the chain back on
Use a slotted screwdriver to rotate the elliptical washer in both directions until the chain becomes tensе
The chain should be neither loose nor too tense
The tire should be in the center of the frame. Rotate the elliptical washer in both directions to move it left and right while maintaining proper chain tension
Rotate the wheel and make sure it spins freely
Put the brake bolt back on
Don't forget the washer which lays between the brake arm and the frame
Insert the bolt and firmly tighten the nut
Install the ribbed washers and firmly tighten the nuts
