Quick 20

The Cannondale Quick 20 is a light, efficient 20-inch bike for kids riding pavement, rail trails, and smooth paths. It is not a small mountain bike, and it should not be judged like one. It is built to roll efficiently and feel quick, especially compared with heavier kids’ bikes.

The aluminum frame keeps the weight under 20 pounds, which is light for this size. The 7-speed drivetrain gives enough range for most neighborhood and path riding, although it does not match the range of more expensive bikes with 9- or 10-speed drivetrains.

The tires match the bike’s purpose. They roll well on pavement but have enough volume and tread for cinder paths and smooth dirt. If your kid is regularly riding trails in the woods, this is not the right bike. The cable-actuated brakes work fine for most kids, but they need occasional adjustment to stay sharp. Buying through REI adds useful mechanical support, including in-store assembly and a year of adjustments with purchase.

At $499, the Quick 20 sits at the lower end of premium kids’ bike territory. It makes sense for kids who mostly ride pavement and smooth paths. If your child is pushing into rougher terrain, look for something with wider tires, more off-road geometry, and stronger brakes.
