1 all day rental of the only tandem designed for your child to sit up front, while the rider in back maintains full control.  Kid's absolutely love it! (Especially those relegated to trail-a-bikes all the time.  Think if that was always your view…)   This high quality tandem is a blast, and can be picked up at Caesar’s Cyclery on San Anselmo Ave.  Front seat accommodates children up to 100 lbs.  Why not bid on 2, so your family of 4 can ride together?
