CHAIN REPLACEMENT Bought our Grandson a mongoose bike and am trying to replace the chain took old chain off and can't remember how to replace it on all the gears can someone help me. all I can find it says mongoose high intensidy and has the shocks on the front end. thanks Pat

I think I can help. Place one end of the chain over the rear gear (doesn't matter which one, the biggest) and adjust the lever or twist ring on the handlebar so the derailleur lines up in a straight line with it. Pull the chain from the rear sprocket down and over the pivot wheel and back over the bottom wheel so it looks just like this S and the end comes forward. Join the chain links. Place the chain over a couple front teeth and turn the pedal carefully until the chain seats on the front sprocket.
