I use a small soft (plastic or rubber) hammer and tap the bearing gently
around the edges and they come off after a minute!

The metal sealed bearings have less rolling resistance than the rubber
sealed bearings, but the metal sealed ones don't seal dirt and water as
well as the rubber sealed flavor.

Use rubber sealed bearings on a unicycle that you ride outdoors in the
elements. Use metal sealed bearings on a freestyle unicycle that you
primarily ride indoors.

If the bearing is tight on the hub you're going to need a bearing
puller. If the bearing is not so tight you may be able to tap it off
using a hammer and some other tool or wedge. Just be careful not to
damage the hub or the flange. Using a bearing puller is much much
easier and is the recommened way to remove the bearing.

The kind of bearings we speak of are not designed to take significant
lateral stress between the inner and outer race. It would be OK if you
tap the inner race (but how?), or if you tap real gently. But if it
doesn't easily come off, a bearing puller is the way to go.

I think that a bearing puller is well-worth the investment. I use mine
often. The bearings often do not stay put and you have to make slight
adjustments. Pounding on (or off) a bearing is often tough. I have
damaged the flange of the hub trying to get a bearing off without a
bearing puller. If the cost is a barrier to using a puller, barrow one
from a bud or go in together to get one with other unicyclists in your
area's club. (Don't have a club? Start one!) I think that tools are one
of the best investments that you could ever make. I still use the tools
that I got when I was 12 - 36 years ago. I assure you, that bearing
puller that you are eyeing will out live you!
