As the only long-term members of Rapid Transit Cycleshop staff who have small children, owners Chris and Justyna have experimented with a variety of bikes and attachments that allow you to cycle family-style.
Our kids are now six and ten years old, and can actually assist in pedaling (for cycling with smaller children, clicke here).
One of the most useful pieces of child-friendly cycling equipment is a trailer bike, pictured in the photo below.
The one we own is a Burley Piccolo, which is unfortunately no longer in production (UPDATE, they are back in business!) . However, Adams Trail-a-Bike offers a range of trailer bikes at prices starting at about $170. (Please call Rapid Transit for availability at 773-227-2288).
What a trailer bike allows you to do, is to convert any upright adult bike into a tandem within minutes, so you and your child, even as young as four or five, can cycle together. The child does not have to pedal, but if she does, you will definitely notice her contribution.
Because we cycle with our children frequently, we also have a Bike Friday Family Tandem, that, in our family, essentially serves as a minivan.
Family Tandems are avilable from Rapid Transit by special order. They are highly adjustable, so either parent and either child can ride together. When one of us travels with only one child, we can adjust the seats and handlebars appropriately with just a twist of the allen wrench. When we all ride together, we look like the two photos above.
But here's the best part, if one of us parents has to take both kids along, this is what we do:
