The crankset on that bike has chainrings that are tack welded or riveted on. The only thing you are going to remove is the chainguard (it is bolted on). This crankset is designed to be a throw away. I guess you could go crazy on it with a side grinder.

If you want to go with one front ring, then you need to look into a new crankset and very likely a new bottom bracket to match.


This change also will make resale more difficult, and likely lowers its value. As an entry bike, as you get more into riding, you probably will move up a step or two. I seem to move up in bikes every three or four months (but I always buy used, otherwise, moving up gets a little costly).
