There are three easy alternatives to fix a dropped chain. Start off trying the first two methods to avoid getting your hands dirty and if they don’t work move on to third option.
Method One: While slowly pedaling shift to the bigger gear by using the left gear shifter. If the chain does not pick back up with this tactic try method two.
Method Two: Get off your bike and again shift to the bigger gear. Then pick up the back end of the bike and spin the cranks. If the chain still does not pick up move on to method three.
Method Three: Physically lift the chain and put it back on the chain ring. If you experience any resistance from the chain simply push the rear derailleur forward.
