At the outset I should explain that I am not into bicycles at all. However, I do need to maintain my kids bikes. My son's Cube bike has a fairly standard spring loaded front wheel quick release. ITH my daughter's bicycle has a quick release as shown in the photo. Unlike the "standard" quick release there does not appear to be an easy way to swing out the release lever arm and spin it to tighten or loosen the wheel - the axle frame gets in the way. How can I be sure that I have tightened it properly when there is no reassuring spin till tight action?
Open the lever (it might have 'open' and 'close on either side of the lever) and undo the nut the other side till it clears the lawyers' lips. Remove wheel. When you want to reinstall, have the lever open, tighten the nut 'enough' (iteration may be required) and then close the lever (enough force to dent your palm is about right).
