That may be the easiest and cheapest but not the best. The best is to get a lockable, high quality suspension fork and leave the bike as a mountain bike that can still be used as a mountain bike. If you are going to ride a mountain bike with slick tires and a rigid fork, there are far better choices out there. Personally I commute on any one of these
as they sit with knobbies and everything. I also look for places to ride where I can take advantage of the 'mountain bikeness' of the bikes. Commuting doesn't always have to be about efficiency and/or speed. It can be about fun too.
And, if you are trying to lose weight or build fitness, pushing knobbies on any surface does a better job of it in fewer miles than a road bike.
