One option is just to commute on the bike on rather good days when not so icy. The biggest thing that you have to get used to is you can't turn or lean into anything without slowing down to a snails pace because you can't always see black ice patches. In winter riding is an adventure that takes more time. You have to be more careful and ride slower except when the road is dry and clear.

In some rural areas it is better to commute on frozen back dirt roads or on hard packed snow trails. If you have hard packed snowmobile trails along the highway in winter these can be used and are sometimes safer than the road.
