The short version
- Typical range: £50 – £250 — see the full BMX bike 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.
- List the components: frame, forks, bars, cranks, wheels and hubs, noting anything that has been upgraded.
- Check the frame and forks carefully for cracks, especially around the head tube and dropouts, which is where BMX frames fail.
- Spin both wheels and check for buckles, and test the headset and bottom bracket for play.
The photographs that sell a BMX bike
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 whole bike side on, drive side, against a plain background
- The cranks and bottom bracket area
- Both wheels and hubs close up
- The head tube and dropouts, plus any crack, dent, weld repair or worn part
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 It feels counterproductive, but a listing that shows the worst of an item gets fewer questions, fewer withdrawn offers and fewer arguments at handover.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
Brand, model and key specs: “[Brand] BMX Bike, 20in, Chromoly Frame, Upgraded Wheels”. Chromoly versus hi-ten steel is a genuine value distinction riders search for. List upgraded parts by name, because that is what the price is actually built from.
Then state these in the description, because a buyer who has to ask is a buyer who might not bother:
- Wheel size and top tube length, which is how BMX frames are sized
- Frame and fork material — chromoly or hi-tensile steel
- Component list, noting upgrades and their brands
- Whether the frame and forks are crack free, and any play in headset or bottom bracket
What buyers will actually ask
You will receive the same three messages about a BMX bike. 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.
Measure it and say. BMX is sized by top tube, not frame size, and riders know exactly what length they want.
Check for a sticker or the weight and say what you find. Full chromoly is worth substantially more than hi-ten, and riders can tell.
Inspect around the head tube and dropouts and disclose any repair. A cracked BMX frame fails suddenly under load and is not something to leave for the buyer to find.
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 BMX bike 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 £150 sale — roughly the middle of the range for a BMX bike — 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 | £150 |
| Poshmark | −£30 | £120 |
| eBay | −£20 | £130 |
| Mercari | −£15 | £135 |
| Etsy | −£10 | £140 |
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.

Timing and getting it to the buyer
Lifts in spring and before Christmas. Well-specified bikes with named components sell within days; entry-level department store BMXs are slow and compete on price alone.
Collection is easiest. If posting, it needs a proper bike box with the bars, pedals and wheel removed — and quote the courier before agreeing a price, because bike carriage is expensive.
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 BMX bike worth?
Typically £50 to £250, with fully chromoly bikes and quality component builds well above. See the BMX bike value guide for the grades.
Do upgraded parts add value?
Genuinely, yes, more than on most bike categories. List every upgrade by brand and model — a buyer adds up the parts, and an unlisted upgrade is money you have given away.
Is a cracked BMX frame worth anything?
Only for parts, described exactly that way. Strip the usable components and sell those, because a cracked frame should not go back on the road under a rider.
