Bicycle-towed child trailer:

• Be aware that trailers are lower to the ground than rear-mounted seats, so they may be safer. Bicycle-towed trailers are a safer alternative to rear-mounted seats.

• Make sure the trailer has a sturdy harness.

• Attach a safety flag to the trailer to make the trailer more visible to drivers.

• Be sure to use a trailer made for towing behind a bike. Don't attach a stroller or other vehicle to your bike.

Rear-mounted seat:

• Choose a seat with a high back, a sturdy shoulder harness, and a lap belt. These help support a sleeping child.

• Attach the seat securely to the bicycle.

• Use spoke guards to keep your child’s feet or hands from being caught in the wheel.

Wait until your child is at least 1 year old before having them ride as a bike passenger. Before that age, children don’t have the neck strength needed to wear a helmet or handle bumps from the road. If you have questions, talk to your healthcare provider.

Have your child wear an appropriate helmet (see box below). This should be done even when using a bike trailer.

Make sure the child rides only with an adult.

Don't ride on busy roads. Stay in low-traffic areas, such as parks, bike paths, and quiet streets.

Be aware that the extra weight of the passenger makes the bike less stable. Ride slowly and allow for increased braking time.

Make sure the helmet is appropriate for the size and age of your child and that it fits well. It should be level on top of the head, about 2 finger-widths above the eyebrows. It should not rock back and forth or side to side. The strap should be buckled and snug under the chin. For more information on helmet fit, visit the CDC at www.cdc.gov and search for “bicycle helmet safety.”

If you can, take the child to the store to try on the helmet before you buy it. This helps you find one that fits well. It's also helpful because a child who chooses their own helmet may be more likely to wear it. If you can’t bring your child to the store, measure their head before going to the store.

Make sure there is a CPSC (Consumer Product Safety Commission) sticker on the helmet. This means the helmet meets the CPSC standard for safety.

Don’t use a helmet that has been in a crash. Discard it and buy a new one. A damaged helmet may not protect the head.

Set a good example—wear a helmet yourself!
