Baby carriers for babies have been around since the 1960s, and they’re still one of the oldest types of baby carrier on the market.
But the most popular type of infant carrier is the motorcycle carrier.
With an average of 7,000 pounds per person, that’s a lot for a single-person bike, but it’s also a lot lighter than a car seat.
In a recent study, researchers at the University of Missouri at St. Louis found that bikes in the nursery accounted for an average 6.7 pounds per bike rider in their study.
But even with bikes in there, those numbers are still pretty small when compared to infant carriers.
In the new study, the researchers used a similar methodology as the earlier study to look at infant carrier usage in a nursery environment, but instead of having to collect the bikes in their home, the bikes were placed in a large, empty warehouse and then transported to the study area.
The researchers found that the bike carriers had an average weight of 4.3 pounds, which is around 1.5 pounds less than the bike that they were using in the study.
This difference wasn’t due to a lack of interest in bikes, or the fact that the bikes are bigger than the bikes that they’re used to, but rather because they were placed on bikes that were less frequently used.
“The bikes were the most commonly used types of bikes in nursery environments,” study author Amy Kohns, an assistant professor of sociology at Missouri, told The Washington Post.
“Our data show that there’s a significant amount of bicycle riders in our nursery environment that were using bikes that weren’t in the most common use category.”
Kohn’s team also found that a majority of bikes that the nursery was used to were also used by parents to ride their bikes to and from work.
The nursery also included a bike rack with racks for bikes that parents could use to load and unload bikes.
The bikes also appeared to be more common in the early months of the study than later in the month.
This suggests that when parents go out to pick up their kids, they’re already using their bikes for the first time.
When it comes to bicycles being used by infants, this doesn’t mean that bike use is limited to those who are in the family, as many bike carriers for adults are used by people who don’t share their home.
“A lot of the parents we surveyed didn’t have a bicycle as a primary vehicle of transport,” Kohn said.
“And they used it more frequently than the others.
We don’t know why.
But we do know that bikes are more popular than cars for this age group.”
The study was published in the International Journal of Occupational and Environmental Health and is available on the web.
Kohn also said that the research was a follow up on an earlier study that showed that infants who used bikes for transportation were more likely to have problems with obesity.
