Do you need a cargo bike when a trailer can be had for a fraction of the price?
A trailer is often the right answer. It costs a few hundred dollars against several thousand. It hitches to the bike you already own, which means no new bike, no new storage problem, and no new decision about where the thing lives. It comes off in a minute or 2 when you want your normal bike back. For riding with kids at weekends a good trailer does the job.
So here is where they actually differ, which is frequency and usability.
A trailer is a thing you attach. A cargo bike is a thing you get on. That sounds like a distinction without a difference until it is 8:15 in the morning, raining lightly, and you are already behind. The attaching is what does not happen. Almost everyone who has owned both says some version of this, and it is the single most common reason people move across.
The other difference parents raise, usually quietly, is where the kids sit. In a trailer they are low and behind you, in the part of the road a reversing driver checks last. On a cargo bike they are either in front of you in the box or directly behind you at shoulder height, inside the sightline of anyone who is looking at you at all. Nell in Sydney described choosing hers as picking the safest option available for little kids, and that was her reason for going to a box bike rather than the alternatives.
We picked Tribe Bikes because it felt like the safest bicycle option on the market for little kids.

Neither of those is a knock on trailers. They are the two things that change when you go from riding with kids sometimes to riding with kids as transport.
Rule of thumb, and we do mean thumb. Less than once a week, buy the trailer. More than twice a week, the bike will earn it.
Common questions
Can you tow a trailer with a cargo bike?
Yes, for cargo. It is not a common combination for carrying children, mostly because a cargo bike already has somewhere better for them to sit.
What age can kids go in each?
Both depend on the specific seat or trailer rather than the law. The usual guide is that a child needs solid head and neck control first, which is around 12 months. Check the manufacturer’s rating for the one you are buying.
Do trailers work behind an e-bike?
Yes. The extra assistance makes a loaded trailer considerably easier, which is exactly why many people start there.
