Introduction & definition: what exactly is a longtail?
A longtail cargo bike is a two-wheeled bicycle with an extended rear triangle. The original idea, pioneered by Xtracycle and Yuba, was to add an extension to a standard bike to increase its cargo capacity—for both volume and weight.
A quarter of a century later, longtail bikes have become the most popular cargo bike format in North America. Over time, various improvements and iterations have emerged. The second major shift came with the introduction of bikes like the Yuba Spicy Curry and Tern GSD, which used 20-inch wheels to lower the bike’s center of gravity. The result? Easier handling, better lateral stiffness, and a greater sense of safety for parents. Families would go from “I’m not sure…” to “Wow, I can do this!”—always with a smile after that first test ride.
A bike that doesn’t intimidate
That might sound counterintuitive—not very flashy, right? But it sparks curiosity. Longtail bikes are typically smaller and narrower than what people imagine when they think of a cargo bike. Instead of a big boxy bike that takes up space, these bikes—like the Riese & Müller Multitinker, Tern GSD, or Quick Haul Long—are compact and approachable.
And that’s exactly their magic. Longtails win over families because they are easy to ride, even with two kids on the back. Children sit securely in seats or between safety bars, and getting everyone set up is quick and simple. School and daycare drop-offs become part of a smooth and enjoyable daily routine.
A bike that grows with your family needs
One of the greatest strengths of a longtail cargo bike is its adaptability over time. While the bike frame stays the same, its accessories evolve as your family’s needs change. For example, a one-year-old may start in a child seat, with a pannier or front basket carrying diapers, groceries, or other essentials. As the child grows, they can ride on a cushion between safety bars, with designated footrests and handholds. You can even add a canopy for rain or sun protection—yes, on a longtail!
What Are the Limits of Longtail Bikes?
Longtail bikes are incredibly capable. That said, they’re best compared with box bikes (or front-loading cargo bikes), often called “bakfiets.” Families can go either route—both can carry one or two children. But for larger families, longtails may reach their limits.
Box bikes like the Urban Arrow Family or Winther Cargoo come into their own when more space or seating is needed. They also offer unmatched ease of loading: a box is intuitive to fill, just like the trunk of a car. With a longtail, you can carry plenty—but it requires more organization, using panniers, baskets, or racks strategically.
Some parents also find it easier and more reassuring to see their children in front of them rather than behind. That’s a valid point, but it’s also a personal preference—it depends on what feels right for you.
Lastly, a box bike tends to remain stable even when heavily loaded. On a longtail, when kids fidget, you may feel their movements a bit more. It usually doesn’t affect balance much, but it’s a sensation worth noting.
In the end, none of this is a dealbreaker. Families are incredibly creative in how they make longtail bikes work for them—and they do so brilliantly. It’s just a matter of understanding what to expect and choosing the solution that fits best.
