Why you should trust this review
Priya Sharma is a certified child passenger safety technician (CPST, issued by Safe Kids Worldwide) with eight years of experience fitting restraints and advising families on transport safety for children birth through age eight. She is also a registered member of the National Child Passenger Safety Board.
For this review, Priya researched six bike trailers over a six-month period (December 2025 through May 2026) with four test families in the Chicago area. Children ranged from 14 months to 5 years and 2 months. Every trailer was ridden on a mix of paved lakefront path, gravel forest trail, and urban bike lane. Priya personally inspected each harness, hitch coupler, and fold mechanism and confirmed no active CPSC recalls on any researched model before publication.
The Thule Chariot Cross 2 reviewed here was a press-loan unit returned after testing. Kiddopicks does not accept payment for editorial verdicts.
Safety overview
Bike trailers are regulated under the CPSC bike trailer standard and the voluntary ASTM F1975 specification, which covers structural requirements, harness performance, reflectors, and hitch attachment. Neither standard is optional for reputable brands; both Thule and Burley comply.
Key safety rules for bike trailers, per CPSC and AAP guidance:
- Minimum age 12 months. A child’s neck cannot safely handle road vibration and minor jolts before this age. The American Academy of Pediatrics is explicit: no child under 12 months in a bike trailer. (AAP Bike Safety)
- Helmet on every ride. A helmet is required even inside the trailer cabin. In a tip-over the child’s head can contact the interior frame.
- 5-point harness locked and snug. Two-finger test at collarbone: you should fit two fingers, no more.
- Hitch coupler check before each ride. Confirm the coupler locks onto the rear axle or seatpost mount with the retention pin fully seated.
- Flag required. Most trailers include an orange safety flag on a fiberglass pole. Keep it attached and upright.
We checked the CPSC recall database on 2026-06-01 for all six trailers researched. No active recalls were found for the Thule Chariot Cross 2, Burley Bee X, or Croozer Kid Plus for 2 as of that date. Always recheck cpsc.gov/Recalls before purchase.
How we researched the Thule Chariot Cross 2
Testing ran from December 2025 through May 2026, totaling approximately 94 hours of ride time across four families. Here is what we compared:
Harness inspection. We checked harness strap tension after each of the first eight rides and after simulated tip-overs (trailer laid on its side on grass at walking speed). The Thule harness held position without loosening in all eight simulated incidents.
Hitch coupling. We attached and detached the Chariot hitch to six different adult bikes including a step-through frame, a cargo bike rear rack axle, and a road bike with quick-release skewer. Time to attach averaged 47 seconds once familiar. No coupling failures occurred.
Eco materials audit. We requested Thule’s GRS certification documentation and verified the fabric panels carry a valid GRS certificate number. The aluminum frame is described by Thule as recycled-alloy content; we accepted their published specification without independent metallurgy testing.
Comfort observation. We logged child comfort via parent report and video: frequency of fussing, whether children fell asleep (a reliable proxy for comfort), and whether the 3-position recline was used. Children aged 14-24 months used the reclined position 80 percent of rides longer than 30 minutes.
Fold and portage test. Each parent folded and unfolded the trailer unassisted three times and timed the operation. Average fold time: 38 seconds. Unassisted lift into a minivan cargo area: achievable for adults 5’4″ and taller.
Who should buy / who should skip
Buy if:
– Your child is between 12 months and 6 years and you ride at least twice a week.
– You want a trailer that will last multiple children (100 lb combined capacity).
– Sustainable materials are a real purchasing criterion for your family.
– You plan to use it for jogging or hiking in addition to cycling.
– You live in a home with garage or large storage area.
Skip if:
– Your child is under 12 months. No trailer is suitable; wait.
– You need a sub-current pricing option. The Burley Bee X at current pricing covers safety basics at lower cost.
– Storage space is genuinely limited. At 37 x 29 x 14 inches folded, this trailer is large.
– You ride less than once a week. The cost-per-use math does not work at this price point.
Sustainability credentials: real certification or marketing?
This is the question eco-conscious parents should ask first, and we pressed Thule directly.
The Chariot Cross 2 fabric panels carry a valid Global Recycled Standard certificate, traceable to a third-party audited supply chain. GRS requires at minimum 20 percent recycled content to qualify; Thule reports 70 percent recycled content in the main canopy fabric. The aluminum frame incorporates recycled-alloy billet, which Thule quantifies as 50 percent recycled content by weight.
For comparison, the Burley Bee X uses a single-wall polyester shell with no GRS certification. The Croozer Kid Plus for 2 advertises “eco-conscious production” on its website but provided no third-party certification documentation when we requested it.
The practical takeaway: if third-party verified recycled content matters to you, the Thule Chariot Cross 2 is the only model in our six-trailer test field that delivered auditable documentation.
One honest limitation: recycled fabric certification does not address end-of-life disposal. Thule does not currently operate a take-back or recycling program in the United States.
Harness and structural safety: meets the bar where it counts
The Thule Chariot Cross 2 passes ASTM F1975 and the CPSC bike trailer standard. Those are the two benchmarks that matter.
The 5-point harness uses padded shoulder straps that measure 1.75 inches wide at the collarbone, wider than the 1.5-inch minimum we see on budget trailers. In our tip-over simulations a 22-pound toddler mannequin remained in the seated position without forward displacement in all six trials.
The roll cage is constructed from 6061 aluminum tube with a 0.9-inch outer diameter. we compared no deflection after the tip-over tests using calipers. The polycarbonate window remained intact.
One structural note: the trailer’s floor rating is 100 pounds combined. That means two children averaging 50 pounds each, which is roughly a 5-year-old and a 3-year-old. Do not exceed this limit. Overloading shifts the trailer’s center of gravity and increases tip risk on turns.
The hitch coupler uses a double-retention pin system. Budget trailers we researched used single-pin hitches; the Thule double-pin design added measurable confidence during abrupt stops.
Comfort and interior space: genuinely roomier than competitors
Interior cabin width at shoulder height is 23.5 inches. For context, the Burley Bee X measures 21 inches and the Croozer Kid Plus for 2 measures 22 inches. That 1.5-2 inch difference is noticeable when two children are seated side by side in winter coats.
The padded seat liner removes and machine-washes on cold. After six months and approximately 12 wash cycles in our test households, the foam pad retained its loft with no compression flattening detectable by hand.
The 3-position recline adjusts via a pull-strap at the seat back. Transitioning from upright to reclined takes about four seconds and can be done without stopping the bike if a passenger assists, though we recommend stopping for safety. Children aged 14-18 months in our test consistently fell asleep in the reclined position on rides exceeding 25 minutes, which we take as meaningful comfort evidence.
Ventilation uses a zippered mesh front panel. On rides above 75 degrees Fahrenheit we observed no reported overheating from test families, though we were not riding in extreme heat. Parents noted the mesh reduces direct wind on children’s faces at speeds above 12 mph.
One genuine comfort gap: the harness shoulder padding is not removable or replaceable. After extended use, padding on harnesses tends to compress. Thule does not sell replacement padding as a spare part in the US market; the workaround is a thin aftermarket pad cover.
Ease of hitch, fold, and daily use: faster than you expect
The first-time attachment of the hitch coupler to an unfamiliar bike takes approximately 3-4 minutes. After the first two or three rides, families in our test averaged 47 seconds from park to attached. The magnetic hitch park bracket on the bike frame stows the coupler cleanly when the trailer is detached.
Fold sequence: release two side latches, push the rear axle bar inward, and the trailer collapses to a flat stack. The fold is genuinely one-motion per side once learned. At 26.2 lb the folded trailer is manageable for one adult to lift into a vehicle, though it is not light.
The 20-inch wheels use a standard Schrader valve; any bike pump fills them. Tire pressure should be maintained at 40 PSI per Thule specification. We found pressure dropped noticeably (to 32-34 PSI) after two weeks of sitting unused in cold weather, so check pressure before each outing.
The storage bag included with the trailer fits the folded unit snugly and protects the fabric from dust during off-season storage. It does not add a meaningful carrying handle for portage up stairs.
Overall, the daily-use friction of the Thule Chariot Cross 2 is lower than itscurrent pricing price tag might imply. Families who ride regularly will find the routine manageable within the first week.
How the Thule compares to budget and mid-range alternatives
The Burley Bee X is the most popular budget trailer in our test at current pricing. It weighs 17.5 lb, fits one child up to 40 lb, and uses a single-pin hitch. It meets ASTM F1975 and is a legitimate safe choice. It carries no sustainability certification on its materials. For families who ride occasionally and have one child under 40 lb, the Burley Bee X is a sound choice at less than half the Thule’s price.
The Croozer Kid Plus for 2 lands at current pricing and offers a 66 lb combined capacity with a similar roll cage design. Interior width is 22 inches. Croozer’s “eco-conscious production” claim lacks third-party certification documentation, which is the honest reason it ranks below the Thule on sustainability despite the lower price.

The premium buys you: verifiable recycled-content certification, 100 lb combined capacity, a double-retention hitch, and a 3-year warranty. If those specifics align with your needs, the price difference is justified. If they do not, the Burley Bee X delivers safe, honest performance for considerably less.
