Small chain came off - after only 2 rides. Too loose. I turned the bike over and read the instructions...can't seem to pull the back frame tighter to tighten the chain. (after loosening he bolts, of course) Is there anyway to remove a segment of the chain? Walmart put it together for me.
There is the way to remove the link of chain, but for that you will need a special chain tool. You can buy it on ebay, or, go back to Walmart and ask for proper sizing.
Recheck every link on the chain, some manufactures have installed a clip on the side of one of the link which you can remove, this is so yo can take out any links you don't need , when you get your desired length you put the clip back on and make sure to snap it in place.
