Been thinking about the safest way to bike transport an infant, and one of those cargo bikes (bakfiets or long john) with the bin low to the ground or a trailer with an infant carrier/car seat or equivalent secured in it seems like it would be the safest way. I know lots of people use the Topeak type seats and don't worry about the safety, but lots of people do lots of things.

I then went and searched for some articles to see how infants could be carried safely. Both that I found were fairly negative on it citing the bouncing not being good for them no matter how they were secured.

I realize you can't avoid doing everything out of fear, but it appears to be a legitimate risk benefit analysis.

I agree with RubeRad though, bravo to you for your efforts.
