i have a 2010 eastern cobra bmx bike that i have had for about a week now, the only thing that i have been doing on it is practicing rollbacks. the other night i was looking at my bike and i realized that my cranks have become loose its not noticeable while riding but they are definetly loose i want to know why this is happening and i also want to know how i can fix this
are the cranks loose or the bottom bracket?
if the cranks are loose, just get a 6mm allen wrench and remove the bolts, grease it up a bit and put it back together
if the bottom bracket is loose you need to take off the non-drive side crank and just use an adjustable crescent wrench and tighten the bottom bracket counterclockwise
