When I change the gear from 3 to 2 the gear shifter does not properly change the gear. It will just move to gear 1 then it pops off.
I put the chain back but it still had the same problem.. I don't know what to do . Please help me.

5It needs to be adjusted by someone who knows what they're doing, and also examined for problems. If you have a biker friend who is a bit "handy" with bike stuff they may be able to help you, plus teach you a few things.– Daniel R HicksJun 24, 2018 at 11:52

It would help if you could give more information about what gear system your bike has. I assume you're talking about derailleur gears (the kind where a device pulls the chain from one cog to another that's next to it) -- if so, is the problem at the front or the back? The adjustment isn't too hard to do yourself but getting your local bike shop to do it for you won't cost a lot and they may even be able to do it while you wait, if they're not busy.– David RicherbyJun 27, 2018 at 18:06

Not sure if you are having problems with the front derailleur or rear, but the answer is really the same.
Derailleurs have 3 adjustments:
- High limit
- Low limit
- Indexing
High and low limits stop the derailleur from pushing the chain off the inner and outermost sprockets. Indexing lines the derailleur up with the individual sprockets. It sounds like you have both a limit and indexing problem.
If you are unfamiliar with bicycle maintenance the easiest option is to have a local bicycle repair shop do the adjustment. It's a straightforward process and inexpensive.
If you want to attempt adjustment yourself, there are many good 'how-to' articles and videos available that walk you through the process. My favorites are those produced by the Park Tool Company.
Rear derailleur adjustment is relatively straightforward, front derailleur adjustment is more complicated chain enters the derailleur at different angles depending on the rear gear selected.
