Best time for a baby to ride with you:

As busy parents, many of us choose to travel via road bikes. And although it may or may not be for our own entertainment, it is always questionable to leave an infant back home. Ever wondered how long you have to wait or how old can a baby ride in a bike seat? We are here to answer this question in the most informative yet precise ways ever.

There are many suggestions online as to when you can start taking your baby with you on a bike but who do we follow? Not all babies are of the same height and weight. The general rule, however, is that a child must be at least 9 months old to start riding in the child seat on a bike. This is because the child has learned to balance his/her head on their own. Weight is not a factor looked after enough, so make sure the baby is secure in the seat as well.

FAQs related to baby rides:

The following are some frequently asked questions about baby riding with you on a bike.

  1. How tall should my child be?

Normally there is no height requirement for a baby, but it is better to make sure that the back of the seat is tall enough. This is not just important for posture and comfort, but also for security. Look for a seat that has an adjustable height so you can change the height of the back according to your needs.

  1. What’s the maximum weight support for a child seat?

Most seats go up to 30lbs. Some even go to 34lbs and you are covered since most babies fall below that mark. So, your seat is more than capable of withstanding the weight of your baby and supporting it. One important message to take out of this is to make sure the seat passes all EN standards and is certified by TUV or ASTM safety.

  1. What if my child is too big?

This question often surfaces and needs a good solution. If your child does not fit the baby seat, the best way around it is to ditch the seat and go for a tag-along or a tow bar. Tag along bikes fasten to the adult bike frame and you can sit your child on it. It has pedals also for your child to engage with. However, there is no harness for them so avoid long rides. Tow bars can also help by connecting the child’s bike and your bike with a bar that attaches to the bike frame.


No matter what bike seat you go for, to support your child, just make sure you make the right decision in terms of affordability, comfort, and enjoyment. It is important that your child is of the age, to be legally allowed to ride in a baby seat. Once you have this out of the way, you have a bunch of options available to you as to what solution you settle on.
