The short version
- Typical range: £40 – £200 — see the full bike trailer value guide
- What decides your price: condition, and how well you evidence it in photographs
- Cost to sell here: nothing, at any price
- Category: Bicycles & Cycling
Before you photograph it
Ten minutes here is worth more than anything else you will do. Buyers are deciding between your listing and someone else’s, and preparation is what visibly separates the two.
- Check the five-point harness on every seat and confirm all buckles work.
- Check the hitch and the safety strap, and confirm the correct hitch adapter is included.
- Check the frame for cracks, the tyres for perishing, and the rain cover and mesh for tears.
The photographs that sell a bike trailer
Four photographs do almost all the work. Shoot in daylight, near a window, with the item against something plain — and do not use the flash, which flattens texture and hides exactly what buyers are trying to see.
- The trailer set up, whole, from the side
- The harness inside, laid out
- The hitch and safety strap
- The frame folded, plus the cover, tyres and any tear or crack
Photograph the flaws too. It feels counterproductive, but a listing that shows the worst of an item gets fewer questions, fewer withdrawn offers and fewer arguments at handover. Buyers who can see the damage stop imagining something worse.
Writing the title and description
Capacity, brand and conversion: “Double Child Bike Trailer, Converts to Jogger, with Hitch”. Single or double is the first filter and conversion kits are a real selling point. Say whether the hitch adapter is included, since they are model specific.
Then state these in the description, because a buyer who has to ask is a buyer who might not bother:
- Number of child seats and the maximum weight per seat
- Whether it converts to a buggy, jogger or stroller, and whether those parts are included
- Whether the hitch and safety strap are included
- Frame, harness, tyre and cover condition, and folded dimensions
What buyers will actually ask
You will receive the same three messages about a bike trailer. Answering them in the listing itself removes the back-and-forth, and answering them well when they do arrive is what turns an enquiry into a sale.
Confirm, and name the type. Hitches are model specific and sourcing one separately is both awkward and expensive.
Check every strap and buckle on each seat. It is the safety component and replacements are rarely available for older models.
Say what conversion parts are included. A trailer that also becomes a jogger is worth substantially more and buyers search for it.
Pricing it so it actually sells
Start from the honest condition grade rather than the price you hope for. WishThrift listings use five grades — New with Tags, Like New, Good, Fair and For Parts — and what each grade means is worth reading before you choose, because grading up is the most expensive mistake sellers make. It does not raise the price; it produces a buyer who arrives expecting something else.
The bike trailer value guide prices all five grades for this item. Pick your grade, take the figure, and if you sit between two grades price toward the lower one. Items priced honestly sell faster than items priced hopefully, and on a free platform there is no fee eating the difference anyway.
What you keep, compared
On a £120 sale — roughly the middle of the range for a bike trailer — here is what the commission-charging platforms would take, and what you would keep on each:
| Where you sell it | Fee | You keep |
|---|---|---|
| WishThrift | £0 | £120 |
| Poshmark | −£24 | £96 |
| eBay | −£16 | £104 |
| Mercari | −£12 | £108 |
| Etsy | −£8 | £112 |
Seller-side rates verified 26 Jul 2026 — Poshmark: 20% commission on sales of $15 and above; eBay: 13.6% final value fee, plus a per-order fee; Mercari: flat 10% selling fee; Etsy: 6.5% transaction fee, plus a listing fee and payment processing. Percentages are applied to the sterling figure above; the fixed per-order and processing charges those platforms add are quoted in their own currency and are not included here, so the real deductions are slightly larger. Full breakdown: marketplace selling fees compared.
Timing and getting it to the buyer
March to August is the window, peaking in spring. Convertible models from known brands sell within a fortnight in season.
Folds flat but is still bulky, so give the folded dimensions. Include the hitch and any conversion wheel, which are the parts most often left behind.
WishThrift does not process payments or arrange delivery — you and the buyer agree both directly — so confirm payment has cleared before the item leaves your hands, and keep the conversation on the site so there is a record of what was agreed.

Frequently asked questions
What is a used bike trailer worth?
Typically £40 to £200, with convertible double trailers from known brands above. See the bike trailer value guide.
Do I need a specific hitch?
Yes, hitches are model specific and attach to the rear axle. If yours is included, say so; if not, tell the buyer which type they need to source.
Are old bike trailers safe to buy?
Check the harness, hitch, safety strap and frame carefully and describe all four. Those are the components that matter, and a trailer with a compromised harness or cracked frame should not be sold for use.
