Question

When my BMX bike chain comes off, how do i put it back on?

Answer 1

get a 15mm (a bike shop should have one or a hardware store) loose both sides your pedals should be -  - as if they don't point up or down. pedal on chain side should be close to front rim. grab opposite side of the chain push rim back the chain should be as tight as it can be. if you jump alot of stuff it will not hurt to do in a second. if chain is in a knot best to have a chain tool(they will cost under 27 bucks) learn how to take a chain apart and put it back together. my chain now multi colored and now i can my different brace colors for my girl.

Answer 2

well usually it goes back on while you pedal but if it doesn't you put the chain on teeth at the top of the sprocket and pick up the bike by the seat so the rear wheel is off the ground then grab the pedal and turn the crank and it will go on...if it keep falling off it might be to long but if u cant make it any smaller and it is just naturally too long you might want to get a chain tensioner

Answer 3

For a start it sounds like your chain is too lose so, loosen the back wheel then pull it back tight and tighten the bolts. When your cahin comes off loosen the back wheel and just put the chain back on...simple

Well, on a bicycle without a deraileur, the chain tention is adjusted by moving the rear wheel backwards. Undo the wheel nuts, slide the wheel forward, put the chain back on and then slide it backwards until the chain is tight. Make sure that the wheel is aligned properly, otherwise it will rub against the chainstays and brake pads.
