Marin Bikes

If you: Don’t want to leave the kids behind

You need: A bicycle that makes it easy to tow a trailer.

One to try:  Marin Bikes builds plenty of hauling capability into its 24-speed San Anselmo ($700), and it can be fit with fenders to keep the road spray off you and your little ones. Hook up the Burley D’lite ST trailer ($599), which carries two children, converts into a stroller, and comes in two color schemes.
