# THULE Yepp Maxi Frame Mount Child Bike Seat \| live price, prepared checkout ## Built for shopping agents: what RoboTrunk does for every product We asked shopping agents, including Meta's Muse first-hand, what they need from a store. This is what they asked for, and what we have built. RoboTrunk is working through its catalogue, so a step may not be done for this one yet. Where a step is done per product, the line ends with what is done for this product. - **Deep research:** We read the maker's manual, independent reviews, video review transcripts and the store's own page, and publish each finding with its source and the date read. `check_product` returns them with a source for each. *This product:* 26 checked facts, research depth trimmed read, checked 2026-09-27T10:26:12.753Z, in the [evidence pack](/agent/evidence/anbbaby-com--thule-yepp-maxi-child-bike-seat). - **Receipts:** Every published fact has a receipt showing its source quote. `check_product` and `get_product` return the checked facts that have one. *This product:* each checked fact listed below has one; the source quotes are in the [evidence pack](/agent/evidence/anbbaby-com--thule-yepp-maxi-child-bike-seat). - **Safety:** `check_product` asks the product-safety regulators live (US CPSC, NHTSA and FDA, Health Canada, the UK's OPSS, Australia's ACCC) whether a recall names a product, listed here or not, and flags a match with its notice; a recall never blocks the buyer. *This product:* this page holds no recall result for it yet; `check_product` asks the regulators now. - **Recall watch:** `watch_recalls` tells the buyer if a product bought here is recalled later. - **Second-hand listings:** `check_listing` runs the same recall check on a second-hand listing someone found, and adds what the listing leaves out and the price new. - **The real price:** The full price to the buyer's country, with shipping and tax, each part quoted from the store's policy or, where a part is not settled, what the total depends on: `check_product` and `search_catalog` take the buyer's country and postcode. *This product:* this store's price was read from its catalogue at 2026-10-18T19:50:07.465Z. - **A checkout that finishes:** RoboTrunk lists only stores whose agent checkout it has verified. `create_checkout` prepares the order at the store; `complete_checkout` returns a link to the store's own checkout. The checkout can be finished in either of two ways: the person taps the link in their own browser, or their agent opens it and completes the checkout. RoboTrunk checks the store's total against a budget ceiling before it issues the link. Payment always happens on the store's own page, and RoboTrunk never holds the money. No store pays for placement; RoboTrunk may earn a commission from some stores via their affiliate programs. - **Markdown copy:** Every page has a Markdown copy: [this page's copy](https://robotrunk.com/products/ucp/anbbaby-com/4697127125078.md). - **Photos and ratings:** Search results carry the product photo and, where the store's own page publishes one, its rating (`search_catalog`). - **Fit answers:** `check_fit` answers whether a listing fits a car, pram or bottle, with the exact quote from the store's page, or says it is not known. - **Back-in-stock watches:** `watch_back_in_stock` starts a watch on a listing the store shows as sold out; `get_back_in_stock_watch` shows when it is back in stock. - **Maker's manual:** `ask_product_manual` answers from the maker's manual with the exact passage and page, or says the manual does not cover it. - **Tools and guide:** Every tool and its description is at https://robotrunk.com/mcp; the guide is at [/agents\.md](/agents.md). - **Research from other stores:** Coming soon: reading other stores' listings of the same product as research sources.

Each carries that source's link and the time RoboTrunk read it. 26 checked facts, checked 2026-09-27T10:26:12.753Z. Research depth: trimmed read. Deep read: the store's own data and 8 outside pages \(the store's own product page; manual; spec sheet; review; regulator recall search \(CPSC \(United States\)\); regulator recall search \(Health Canada\); regulator recall search \(ACCC Product Safety Australia\)\), each read in full by RoboTrunk and trimmed to its main content, then written up and checked\. Facts from the maker or a manual quote the page word for word; what real users report is summarised with a link to the page read\. Recall status was checked directly with CPSC \(United States\), Health Canada, ACCC Product Safety Australia: The supplied CPSC and Health Canada searches found no recall for Yepp Maxi Frame Mount model numbers 12020231, 12020232 or 12020234\. The lone CPSC result concerns Chariot trailers, and the Canadian child\-seat recall concerns the different Thule RideAlong model\. The Australian feed also had no match, but it covered only the 100 most recent recalls from 2026\-05\-15 through 2026\-09\-25, so it is not a complete historical search\. - variants: The listed variants are Black 12020231, Blue 12020232 and Orange 12020234\..

Source: (review), read 2026-09-27T10:18:43.495Z. - security and restraint: The two\-action seat release appeared resistant to accidental operation, and the adjustable five\-point harness felt secure while remaining easy to fit around a moving toddler\..

To find them we read the store listing, the manual, the spec sheet, owner reviews and the recall records of CPSC \(United States\), Health Canada and ACCC Product Safety Australia. We also chased the questions below across those sources and found no reliable answer, so you know exactly where the evidence ends and never have to guess. - What are the seat's exact external dimensions? - How much clear seat\-tube mounting space is required? - Which installation tools are included? - Which additional installation tools are required? - What is the precise tightening torque for every fastener? - What exactly is included in the retail box? - What are the warranty duration and coverage terms? - Does the surface coating or colour rub off with use? - How thick is the EVA seat material? - Are replacement harnesses, buckles and foot straps available? - Which current bicycle models have verified fit? - Will it clear this bicycle's tyre, saddle and rear rack? - Can the padding be machine\-washed? - Does the seat fit electric bicycles with seat\-tube batteries? - What is the model's manufacturing date range? To buy this through RoboTrunk, pass merchant `anbbaby-com`, product_id `gid://shopify/Product/4697127125078` and one variant_id from the list above.
