The principial determinant of when an child can join his or her guardians on cycle rides is the strength of the baby's neck. Due to the jostling and the additional weight of a helmet (8-10 oz.), this is a few months after a child can first hold their head up. Note: several jurisdictions have laws requiring passengers on cycles to be a minimum of one year old.

Normally by age one year guardians can start checking with the baby's pediatrician to see if they feature the neck development to safely go for a cycle ride. Many toddlers' neck and shoulder muscles can bear the weight of a helmet and shock from bumps in the road at one year old.

We know of no comprehensive study on the prime method to transport a baby on a cycle and there are risks associated with all of them.. Here are some factors to consider:

Backpacks

Carrying a baby on a cycle in a backpack is possibly highly dangerous -- and illegal in many jurisdictions. Some of the problems are: The center of gravity is more; if you wear helmets -- as you ought to -- your helmets could collide together; the child is rather unsafe in a accident because the distance is higher and there is a higher chance of the child ending up below the parent in a fall; plus the backpack provides lower protection than a babyseat or trailer.

Baby Seats

Physics tells us that a baby, in a baby seats, mounted on a cycle, heightens the center of gravity of the cycle. This modifies how the cycle controls and heightens instability. The bike's build geometric also articipates in stability ? greater chain stays are an element that aids. The greater the child the larger the impact. But, the weight of a child is negligible compared to the size and strength of most adults so often the change in balance is not unacceptable. If you need to rehearse before you put your child into the child seats, load a book bag with the child's weight in books and attach it into the seat and take it for a ride.

Baby seats tend to work acceptably for children 1-3 years old. There is anecdotal evidence of infants of 15-20 kgs., or 33-44 lbs., being taken in child seats. In fact infants tend to become too tall for child seats before they grow too heavy.

For most users the most arduous aspect of child seats is usually getting the child into and out of the seat, especially with pronominal rack mounted seats (as opposed to front top-bar mounted seats). One danger of cycle seats is not when the bike is being pedaled, but when it is stopped. When the rider gets off the saddle, or dismounts, it takes additional effort to maintain the bike's balance and keep it upright. Petiter adults usually have the most difficulty loading and unloading the child. If the parent can manage this usually they are able to ride safely with a child seat.

Baby seats certainly have the advantage, especially in an urban area, of not adding to the size of the "foot print" of the cycle, which could minimise harassment by drivers.

In the occurance of a crash, with pronominal child seats -- even a wonderfully designed one with loads of safety features -- the child will probably suffer at least small arm and neck injuries. With badly designed pronominal mounted bike seats, there is also some danger of the child's foot getting caught in the spokes. In the USA, child seats ought to comply with the ASTM 1625-00 safety standard.

A variation is "front-mounted" child seats. They are hugely fashionable and have been used in Asia and Europe for many years. They are less common in North America. A lot of people swear by these because it is easier to keep an eye on the child and chatter with them, and get the child in and out with larger ease. In the event of a accident, in a lot of ways the child is more protected than with a pronominal mounted child seat, and people often say an accident is unlikely as balance is better and there are fewer distractions from behind you.

Note: We have one description of the convergence of a childs'size, with his helmet getting hooked on the top lip of a pronominal seat resulting the straps block his airway. The emergency was caught in time so that a trauma was averted. If your toddler is behind you, this makes known the importance to mind them regularly, possibly with a rear view mirror.
