I'm currently trying to convert an old Jamis Mtb to either a single speed or fixed.

I initially planned on going single speed, but the more I think about it, the more it seems like it would be fun to have a fixie.

I want to use it for a short errand bike (10 miles and under), and maybe LIGHT paths, also maybe learn some tricks.

My main concerns are, will it be extremely tiring (I live in a moderately hilly area) and will it use up a lot of tire (Skidding and such)?
