How can you take some slack out of the chain on an Electra cruiser?
My brother and law told me that the chain on his cruiser bike jumped when he hit a small bump (he lives far away from me in another state) ask me how to take the slack out of the chain?

I have a road bike and a fixed gear and that's easy to fix as we all know-loosen the skewer/lug nuts and pull the rear wheel back. The next step would be removing a link or using a chain tensioner..

But aren't bikes wit coaster bikes different? Any help please!
