Buy lights and go for night rides, get up early enough to sneak a ride in and have a real flexible work schedule. If you can get all three in you can work around the kid till their old enough to hopefully join you. Mine liked riding the trail-a-bike once they were big enough to do so which was a great way to get them to school. At 2 years difference each, one was off the trail-a-bike by the time the next needed it. Now I do day and night rides with the kids and they have fun with it which isn't as good speed/mileage wise for me but time on the bike is time on the bike. Friday I'll sneak out at 7pm for a night ride in the woods with a group. It does get better.
