DannoXYZ: I followed the steps you posted and made some other small adjustments, and now I am able to shift through all three gears with relative ease. Thanks a lot for your help!

Andrew: You're right, adjusting a derailleur should be a simple thing to do. It's just that up until about 10 minutes before I started this thread, I didn't even know what a derailleur was, let alone how to properly adjust one. But thanks to everyone who replied, I'm now able to use my bicycle again.


Sorry for the late reply. I was unable to try this out earlier due to illness.
