Does anyone have any experience or references on when it is ok to start putting a child in a bike child seat/carrier?

I am aware that our child will need some extra neck strength to not bobble around too much with the added weight of having a helmet on his head.

The Bicycle Helmet Safety Institute, the US Consumer Product Safety Commission and the American Academy of Pediatrics agree that:

...children under 1 year of age should not be on bicycles. Children are just learning to sit unsupported at about 9 months of age. Until this age, infants have not developed sufficient bone mass and muscle tone to enable them to sit unsupported with their backs straight. Pediatricians advise against having infants sitting in a slumped or curled position for prolonged periods. This position may even be exacerbated by the added weight of a bicycle helmet on the infant’s head.

In some US jurisdictions it is illegal for children under the age of 1 to be passengers on a bicycles as well.

    Does anyone from outside the USA (Australia, Europe, UK, etc.) have info like this? I'd like to see if there is a commonly accepted standard.

  • @David HAust - that's a reasonable question, but wouldn't you think that the bones and muscles of toddlers everywhere develop at roughly the same rate? While this is an 'American' suggestion, it seems valid worldwide.

    Haha. Yes, they do grow at the same rate everywhere ; ) I only asked because it seems anything involving kids is very prone to polarised opinions so I was simply seeking a counter-point. No offence meant to 'american' suggestions. Perhaps asking for info from different geo regions was the wrong way to go about it. My bad.

  • @David HAust - No offense taken. I am interested in other geographic area responses as well.

    Late comment, but that recommendation is for the mythological average child. The recommendation for being able to sit unsupported is good, but when that happens can vary widely, some kiddos are even walking by about 9 months, others not until 17 months. 1 year is a good average, but some kids will be ready sooner, and others need more than a year. The parent will have to make a judgement call. Apr 13, 2020 at 18:44

In the Netherlands the accepted age for first bicycle rides is about 9 months. The main point to watch out for is that many bicycle seats are a bit big for children that age so you have to take special care they can't bounce or climb out.

Recently bicycle adapters for maxicosi chairs have appeared such as the one below. Thus you can also transport babies on a bicycle:

If you have a cargo bike you would typically use one of these for your baby.

  • However in the Netherlands most bike rides are on "nice" cycle paths and may be much shorter then in the USA.

  • True, I was assuming the original question dealt with the physical abilities of the child. Oct 26, 2010 at 12:39
  • How do the dutch move babies under 9months old? Walking/car? Walking in US is often pretty impractical due to distance and maybe there is more need for more "solutions" on how to strap baby car seat to a bike cart for example

  • @Ville M: something like the seat I added to the picture, or various baby shells that fit in cargo bikes such as the christiania bike. May 10, 2011 at 6:54
  • Not recommended but a lot of Dutch babies were transported on bikes in baby carriers (on mothers front) as soon as the mother felt up to cycling again.

If you use a trailer its pretty much the same as using a pushchair (stroller) and indeed some double up (I wouldn't get one that doesn't) - you'll get a 5 point harness, a seat that reclines and you can get head cushions and the like too.

Of course a trailer may not be practical in your circumstance (though I'd be surprised) but if it is it also helps deal with the problem of all the other stuff you want to carry when going out with a small child.

One other option for practical as opposed to more recreational use is a cargo bike or trike of some sort - I'd've loved one of these a Nihola or a Christiana Trike - in which you can put the same seat/carrier you'd use in a car 'til they're of a size to sit up. There are also Dutch cargo bikes that can similarly be equipped with benches, rain covers, etc. But I'd probably still have wanted a trailer too for longer rides (-:

  • I hadn't thought of the trailer. I like the idea of the extra carrying capacity and the five point harness, but it could be a bit more cumbersome. The cargo bikes look interesting but buying a new bike is not an option (unfortunately).

  • I think trailers are wonderful - they have also evolved significantly (in most respects) from when I got mine some 15 years ago. Cumbersome... yes, maybe, ish. I think it depends on your intended use. Some have concerns about visibility - but I never found that to be an issue.

As others stated, for sitting in a bicycle seat the child should be able to hold their head (9~12mo).

But in a Bakfiets (e.g. Babboe) you may transport even newborns in a Maxi-Cosi, with much care of course.

ThisMomBikes has a nice and long blog post about biking with babies.
