First you need to figure out what kid of gearing it is, and what's important is the number of sprockets at the rear wheel. I'm assuming that you're talking about a 6 speed rear for the 18-speed and a 7-speed rear for the 21-speed. If that is the case there is a risk that the 6-speed rear has a narrower hub than the 21-speed. This can make it awkward. But the biggest issue is probably the shifters. a shifter intended for 7 rear sprockets will not shift cleanly over 6 sprockets.
What else can I help you with?
What would it hurt to put a rear wheel from an 18 speed bike on a 21 speed bike?
