Baby seats are allowed to kids of a minimum age of 12 months. In most cases kids will fall asleep and consequently need to be strapped in their seat. In the USA kids are strapped in the rear of the bicycle not in the front. Helmets are compulsory but not always used. Baby seats in the rear or in the front of your bicycle are simply a very bad and crazy solution. I don’t know who does allow such solutions in a modern society? And whatever literature you will find on the subject to justify it is simply hopeless crap. You don’t need to be a specialist to understand that positioning a kid on a bike is highly unstable and bloody dangerous. You must be absent minded to consider putting a child on a baby seat due to the simple facts: that a bike has no initial stability, that jumping on your bike requires you to pass your leg above the baby seat‘s head if you are a male, that a simple lateral wind can overthrow your bike sideways. Some experts will tell you that a trailer is safer because the height involved is less important and consequently safer. That may be true but a trailer is not going to be visually seen by a car driver and might be even more deadly than sitting on the rear of a bike. Let’s not be hypocrites here. Driving your bicycle with a baby seat is as dangerous as waiting for the metro to arrive in a station. No one assumes that you could fall off the platform in front of a coming metro, that no one will jump to commit suicide or that someone will be dragged under the coach because his coat was been pinched in the automatic doors, nor that someone had bad intentions and push you down the track. All these facts occur but we all do agree that they have to be considered as abnormal uses of the system and we live with them on a daily basis. This being said metro systems were designed long time ago and safety matters were not their primary concern and not much safer than the first steam trains we put on the tracks for the first time. Today some stations are being equipped of automatic sliding doors preventing the above mentioned incidents. If these implementations have greatly improved the safety of some stations what about regulations of baby seats on bicycle? Here is some information provided by: From street blog USA: Tuesday, October 15, 2013 that documents the matter and its urgency to act. Bicycles are simply bloody dangerous when kids are involved.
“It’s extremely risky,” Dr. Agran told me. “If you’re hit by a car, there’s a good probability — if you look at the weight of you, your bicycle and your infant and you look at the weight of a car — there’s a high probability that you and your child would be killed.”
“It’s basic common sense,” she said. “It’s physics: mass times acceleration.”
While I worked the lump out of my throat, she went on, “I personally would not ride a bike with a child in it on the street. I would be very frightened that someone texting, someone on a cell phone, someone not coming to a full stop, someone distracted, someone cutting into my lane would kill me and my child.”,” even properly restrained infants can die in a car crash “because they’re fragile.”
Agran says in her community of Orange, California, at least, more kids are killed on bikes than in cars. “I don’t even remember the last time a child was killed in a car crash, whereas we’ve had a number of bicyclists,” she said. Nationally, between 1999 and 2010, 37,410 children 19 and under were killed in car crashes, compared to 1,710 killed on bicycles.

Baby seats are often associated with bicycle because of speed and infrastructure with reserved lanes but when it comes to urban traffic and missing infrastructure it becomes a highly dangerous equation that you want to avoid at all costs. When we refer to scooters or motorcycles baby seats are simply impossible to imagine due to speed and lack of basic safety design. These mobility tools are simply not designed for that purpose.
This proves in fact that bicycle are tolerating baby’s eats only because of speed reasons but nothing else because they prove to be as unsafe as scooters or motorcycle in traffic situations.
