The InStep Sync makes the most sense for families who usually carry one child and want a compact, easy-fold trailer for lighter bike days. It is the kind of simple bike-only option that works when your routine is mostly neighborhood loops, park paths, and occasional weekend rides rather than heavier mixed-use family transport.

That simplicity is also the warning label. You give up the space, flexibility, and higher-end comfort that make stronger two-seat or crossover trailers easier to live with for broader family use. It works best when a one-child trailer is genuinely enough and low ownership friction matters more than extra capability.
