Introduction: One Kid or Two—Make the Smart Choice
Choosing between a single or double kid’s bike trailer isn't just about how many kids you have—it's about your lifestyle, space, terrain, and future-proofing your purchase. In this guide, we break down the differences to help you decide with confidence.

When to Choose a Single Trailer
✅ Ideal for parents with one child
✅Best for city riders and narrow bike lanes
✅ Lighter and easier to store in small apartments
✅ Great for commuting or short daily trips
“I use mine to take my son to daycare. It’s light, easy to fold, and perfect for quick errands.” — Bella R., Toronto
When a Double Trailer is Worth It
✅Great if you have two kids under 6
✅Want room for toys, picnic bags, or groceries
✅You’re planning longer weekend rides or vacations
✅ Roomy interior means more comfort and less sibling squabble
“Even though we only have one kid, we chose a double—it gives us space for his backpack, snacks, and the dog on short trails.” — Mark & Eliza, Boulder CO
What About Future-Proofing?
If you're planning to have a second child, the double trailer becomes the more economical and versatile choice. It also has better resale value when your kids grow up.
Pro Tip: Many double trailers come with adjustable harnesses for 1 child centered or 2 children side-by-side.
