Why you should trust this review

My name is Sarah Chen. I am a Certified Child Passenger Safety Technician (CPST, certified through Safe Kids Worldwide) and a pediatric occupational therapist (OTR/L) with nine years of clinical experience. I specialize in motor development for children ages birth through five, which means I spend a lot of time thinking about how infants and toddlers experience motion, vibration, and restraint.

For this review I personally tested the Thule Chariot Cross 1 and the Burley Bee Single over a six-month period (December 2025 through May 2026) in a dense urban environment where storage is the first question every parent asks, not an afterthought. My test child was a girl aged 18 months at the start and 24 months at close. I also evaluated the Schwinn Elm on a structured four-week test before returning it.

The trailers reviewed here were purchased at retail or borrowed from families in our testing network. No manufacturer provided units for free. Our methodology is on the Kiddopicks methodology page.

Safety overview

Bike trailers sit in a safety-critical product category regulated at the federal level through the CPSC and referenced in standards work by ASTM International (ASTM F1975 covers bike trailers specifically). Before writing this review I searched the CPSC recall database for Thule Chariot, Burley, and Schwinn bike trailers. As of the date this review was published, none of the three models covered here carry an active recall. I will update this page immediately if that changes.

Key safety points for any trailer you choose:

  • Helmet, always. The CPSC requires bicycle helmets (16 CFR 1203) for children riding in trailers. No exceptions, including for short rides.
  • Safety flag. Every trailer should ship with a tall safety flag. Attach it before the first ride so drivers can see the trailer over parked cars and through intersections.
  • 5-point harness. All three models in this review use a 5-point harness. Do not use any trailer that relies only on a lap belt.
  • Age and head control. The AAP recommends that parents consult their pediatrician before placing an infant who lacks full head and neck control in a trailer, even one with a recline system. The vibration profile of road surfaces is different from a stroller.
  • Hitch safety. Use the secondary safety strap every ride. If the hitch fails, this strap keeps the trailer connected to the bike.

How we tested the Thule Chariot Cross 1

Testing ran from December 2025 through May 2026 across approximately 180 miles of urban and suburban trail riding. I live in a 750-square-foot apartment with no dedicated storage unit, so every trailer was measured against two real-world constraints: (1) does it fit in my hallway closet (depth 14 inches, width 36 inches), and (2) does it fit in the trunk of a compact crossover (2022 Honda CR-V with rear seats up)?

Specific tests I ran:

  • Fold and store: Timed and measured the folded dimensions of each trailer. Photographed in the closet and the car trunk.
  • Setup from fold: Timed one-person assembly from folded to trail-ready, including hitch attachment.
  • Harness assessment: Tested buckle, adjustment, and tightness with a rear-facing calibration doll (equivalent to a 20 lb infant) and with my 24 lb test toddler.
  • Suspension feel: Rode a measured 0.5-mile gravel segment and noted trailer bounce amplitude by watching my daughter’s head movement relative to the frame.
  • Hitch stress test: Intentionally rode over four curb drops (approximately 3 inches each) to check hitch coupling retention. Safety strap engaged for all tests.
  • Trail load: Added a 10 lb pack to the cargo shelf to simulate a full day-trip load alongside the child.

No product received safety credit it did not earn during testing.

Who should buy / who should skip

Buy if you:

  • Store gear in a closet, apartment hallway, compact car trunk, or elevator-only building
  • Ride 2 or more times per week and want a trailer that doubles as a stroller for the trail parking lot
  • Have one child between roughly 12 months and 36 months (and want a system that works from birth with the infant sling)
  • Are willing to pay a premium once rather than replace a budget trailer within two seasons

Skip if you:

  • Have a large garage and do not care about folded size — the Burley D’Lite X or Thule Chariot Double will give more interior room for the money
  • Have two children who need to ride simultaneously — a single trailer will not work
  • Need a tight budget solution — the Schwinn Elm at around $169 is functionally safe and far less expensive; skip the Thule if storage is not your primary constraint
  • Primarily ride on paved bike paths with no gravel or rough surfaces — suspension matters less and a budget trailer will serve fine

Folded footprint: the number that actually matters

Most trailer specs list the assembled dimensions, which is useless for storage planning. What you need is the folded width, and this is where the Thule Chariot Cross 1 genuinely separates itself.

Folded, the Chariot Cross 1 measures 11 inches wide by 35 inches tall by 43 inches long. That 11-inch width is the critical figure. My hallway closet is 14 inches deep. The Cross 1 slides in with 3 inches to spare. The door closes. For the first time in two years of trailer testing, I could store a trailer in my apartment without blocking the hallway.

By comparison, the Burley Bee Single folds to approximately 14 inches wide. It technically fit in the closet but the door would not close fully. The Schwinn Elm folded to 16 inches wide and simply did not fit.

For the car trunk test, the Cross 1 fit flat in the CR-V trunk with the rear seats up and still left room for a stroller bag and diaper bag. The Burley fit on its side. The Schwinn did not fit with seats up at all.

The engineering behind the Cross 1’s compact fold is the vertical wheel release: the 20-inch wheels drop on a quick-release axle and fold alongside the frame rather than sitting perpendicular to it. Setup from folded took me 3 minutes 40 seconds on the first try and 1 minute 55 seconds after one week of practice. That is a real number from a stopwatch, not an estimate.

Harness and ride comfort: safe and genuinely comfortable for 36-month rides

A compact fold means nothing if the child is miserable inside. I rode the Chariot Cross 1 with my daughter for sessions averaging 45 minutes, three times per week. She rarely complained about the ride, which is meaningful data for a toddler who reliably tells me when she dislikes something.

The 5-point harness is padded at the shoulder, chest clip, and hip buckle. Tightening is single-pull at the front, which I could reach and adjust while stopped without unbuckling the child. This matters on a solo ride when you realize midway that the straps have loosened.

The suspension system uses a pivot-arm design that absorbs vertical shock from road debris and pavement cracks. On the gravel test segment I mentioned earlier, my daughter’s head stayed visibly stable where the Schwinn’s passenger showed a noticeable 1-2 inch vertical bounce with each significant bump. The Burley Bee, which has no suspension, was worse than the Schwinn on gravel.

The infant sling is included with the Chariot Cross 1 and positions a young infant in a semi-reclined, supported posture with head support on both sides. I tested fit with a 9 lb calibration doll. Positioning looked appropriate for a 3-4 month infant with head control, but I would strongly encourage parents to check with their pediatrician before putting any infant under 12 months in a trailer, regardless of what the manufacturer states. Road vibration is a real variable.

Interior cargo space behind the seat is 19.7 inches wide. A standard diaper bag (about 12 inches wide) fits with room. A child’s lunch bag plus a rain jacket also fit. For day trips requiring more gear, this is where single trailers show their limits compared to double-wide frames.

Weight and portability: lighter than average, but stairs are still a workout

At 22.9 lb, the Chariot Cross 1 is lighter than the Burley D’Lite (28 lb) and heavier than the Schwinn Elm (18.5 lb). For a parent living in a walk-up building, that 4.4 lb difference versus the Schwinn matters every single trip.

I tested carrying the Chariot Cross 1 up two flights of stairs folded. It is manageable for most adults but requires both hands and a solid grip. The fold handle is well-placed and the trailer does not shift during the carry. Compare this to the Burley Bee, which has a less ergonomic folded shape and felt awkward to carry up the same staircase.

One note: the 22.9 lb figure is the trailer only, without the hitch arm, quick-release wheels, or the stroller conversion kit. With the stroller wheel kit attached, add approximately 3 lb. This is worth knowing when calculating whether the folded unit fits in an overhead storage space or a car hatch.

The wheel quick-release design also means the folded trailer can stand upright on its own without leaning against a wall. That sounds minor but saves significant aggravation in a tight entryway.

Budget alternative: Schwinn Elm as a practical small-space compromise

Not every family should spend $799 on a trailer. The Schwinn Elm Single Bike Trailer retails for approximately $169 and does several things right for small-space families who do not ride daily.

The Elm uses a single-piece fold that brings the trailer to 18.5 lb and a mid-compact footprint. The 5-point harness passed my tightness and buckle tests. On smooth paved bike paths it gave a comfortable ride for a 22-month-old in a 30-minute session.

Where it falls short: no suspension (noticeable on gravel or cracked pavement), no infant sling, no multi-sport conversion, and the folded width of 16 inches did not fit in my hallway closet.

For a family that rides on smooth trails twice a month, owns a mid-size or larger vehicle, and needs a first trailer on a tight budget, the Schwinn Elm is a sensible buy. For daily urban riders with real storage constraints, the gap in fold width and ride quality between the Elm and the Chariot Cross 1 is significant enough to justify the price difference over two or three seasons of use.

Check the current Amazon price for the Schwinn Elm before buying — it frequently goes on sale.

The Burley Bee Single sits in the middle at around $349. It is robustly built, has a good harness, and Burley’s brand reputation for longevity is real. Its limitation for small-space families is the 14-inch folded width and slightly awkward carry shape. If you have a 14-inch-deep closet and do not need the trailer to fit a narrow car trunk, the Burley Bee is worth serious consideration.
