How to install Quick Release
The front tire of your Pulse attaches with the Quick Release system to allow quick installation or removal of the tire. To roll safely it needs to be tight.
To do this, place the tire in the quick release, grip the black piece on one side with two fingers, turn the lever on the other side until resistance is felt, bend that lever up.
The lever should be so tight that it cannot be released easily (you should have to exert quite a bit of force with your hand to release it).
