8 Best Bike Trailers for Kids

Both kits come in the box. That sounds like a footnote until you have shopped a trailer and a stroller separately, tried to store both, and discovered that the second one always lives in the way. The Coaster XT arrives ready to tow and ready to push, with the strolling wheel kept on board when it is not in use.

We think it is the best-built trailer here, and the difference shows in the small places: an adjustable handlebar that suits a tall parent as well as a short one, a fold that goes genuinely flat, and a rear cargo hold big enough that the diaper bag stops being a negotiation. The suspension earns its keep on chip seal and broken pavement, and both children ride without the jostle a rigid frame passes straight through.

Seating is rated for two children at 49 pounds each, the highest per-child figure in this group, on a 30.2-pound frame. Compatibility is broader than most as well: the axle mount suits fat-tire bikes, and the accessory range includes an infant sling for a younger sibling. The trade is that you carry stroller hardware on every ride whether you use it or not, and a wide track plus that weight is what you feel on a climb. If you only ever tow, a plain trailer is lighter and simpler for the same trips.

Twenty-one pounds is what an aluminum frame buys you, and it is the number that matters at the end of a ride: this is the trailer you pull off the hitch and carry up a flight of steps without thinking about it. The wheels snap on with a push, the pins are the only loose parts worth keeping track of, and the folded package drops into the trunk of a small car.

One child, 40 pounds of passenger and 12 pounds of gear behind the seat is a tighter brief than the doubles, which is exactly why the cabin feels generous for a single rider. There is room for a toddler to grow, pockets within reach for a bottle and snacks, and air-filled tires that soak up pavement seams without rattling the passenger.

Both a bug screen and a weather shield are fitted rather than optional, so a drizzly start does not force a choice between rain cover and airflow. We came away thinking this is the least fussy trailer here: nothing about it asks for a second person, a tool, or a dry run in the driveway.

Where it gives ground is simply the rider count. There is no second seat and no sharing, and for a family that is finished at one, that is not a compromise but the reason the cabin is this comfortable and the frame this light.

Twenty-inch air-filled wheels are the reason to look here. They roll over curb lips, packed gravel and the root-heaved sections of a rail trail with noticeably less crash and bounce than the 16-inch wheels most of this group uses, and on a long paved path that is the difference your children feel rather than the one the spec sheet lists.

The rest is sensible family kit: two children at 40 pounds each, a 12-pound cargo well behind the seats that swallows a diaper bag and a thermos, a canopy carrying both a bug screen and a weather shield, a vented rear window, and a safety flag included rather than sold separately.

Assembly is quick: the frame unfolds and locks, the wheels go on with a push, and the whole thing collapses small enough for a closet or a trunk. The five-point harnesses have shoulder pads, the side windows are big, and nothing about the interior feels like the cheap seats.

The catch is the cabin. Two toddlers fit; two four-year-olds start negotiating for leg room, and the side pockets are tight enough that a sippy cup is a squeeze. We think it is the best double here for rough pavement and for riders who are still small, and if both children are already in school, the Thule’s extra nine pounds per child is the difference worth paying for.

The moment that earns this trailer its place is the one at the park: unhook from the bike, drop the stroller wheel, and push, with a sleeping child who never has to be unbuckled. That is the whole argument for a convertible, and we think this is the cheapest way to get one here, without a second frame taking up space in the garage.

Day to day it is a 31.8-pound steel trailer that folds flat, sheds its wheels on quick releases and fits the trunk of a small coupe. The canopy carries a bug screen and a weather shield with a rear vent, and the five-point harness works the same whether you are towing or pushing, so there is no rethreading when you swap modes.

Compare it with the Thule and the difference is polish rather than function: simpler fabric, a fold that takes more of a shove, and the plain universal coupler that bolts to a rear axle. What you keep is the part that matters, which is the ability to ride somewhere, park the bike and carry on with the day on foot.

Thirty-four and a half inches is the number to measure before you fall for the rest of it. That is the width in stroller mode, and it is wider than a lot of interior doors, which turns a quick errand into a search for the accessible entrance.

Get past that and we think there is a lot of trailer here for the money: a pivoting front wheel that actually steers, a handlebar brake that holds it on a slope while you wrestle a toddler out, reflectors on all four sides, and a cargo hold deep enough for a week of groceries, let alone a picnic. The seat sits higher off the ground than the low-slung trailers here, which is what makes a gravel driveway and a grassy park manageable.

The weight limit is 88 pounds across two children, each with their own harness rather than a shared belt. It is the trailer to choose when the push and the jog matter as much as the ride, and the one to walk away from if your daily route includes a narrow front door or a tight hallway.

Eighty-eight pounds across two seats puts this alongside trailers that ask noticeably more, and the rest of the spec list does not read like a budget compromise: two five-point harnesses on separate seats, 16-inch air-filled tires, reflectors and reflective strips down both sides, and a rear pocket that takes the day’s snacks and a folded jacket.

It also converts to a stroller for the parts of the day when the bike stays parked, and it folds compactly enough to live in a trunk between outings. At 34 pounds it is on the heavy side to lift onto a rack, and the 16-inch tires are happiest on pavement and packed gravel rather than anything looser.

We came away thinking the hardware is the story here: 88 pounds, two proper harnesses and a stroller mode at the bottom of the price range. It is the pick for a family that wants capacity without paying for a badge, and that is comfortable keeping its own tires, buckles and canopy in order.

This is the plain version of a bike trailer: one seat, an alloy steel frame, a set of 16-inch air-filled tires and a canopy with a bug screen and a weather shield. Nothing about it is clever, and that is the appeal if the trailer gets used a few times a month rather than every day.

It folds down for storage, the wheels come off on quick releases, and there is a cargo pocket behind the seat for the snack-and-juice-box haul that comes with a two-year-old. Folded, it is about 32 inches long and stands behind a door.

Two things to sort before the first ride. The coupler plate bolts to the rear axle and some 29ers will not take it, so test-fit with the bike upside down and keep track of the pins. And the air-filled tubes want watching: keep them at the sidewall pressure and carry a spare, because a flat six miles from home with a child aboard is a long walk.

We think it is a decent small trailer, and for one child on local rides it does everything asked of it. If there is any chance of a second rider, though, the InStep Quick-N-EZ gives you the same fold plus stroller mode for barely more.
