The second-hand bike market has changed character in the space of a few years. After a spell of shortage when anything would sell, supply is plentiful again, unsold new stock has dragged prices down, and the gaps between segments have widened.
For a seller as much as for a buyer, the point is not to know an average price — that figure means nothing — but to work out where a particular machine sits in a very uneven market structure.
Asking price versus selling price
First point, and the one most often missed: online listings show asking prices, not transaction prices. The average gap between the two runs at around 10 to 15% on bikes, and more on adverts that have been sitting for over a month.
The practical consequence is that copying the price of the first listing you find for an identical model will lead you to overvalue. The right method is to pull together five to ten listings for the same model and the same year bracket — on Buycycle, Pinkbike, Gumtree or eBay UK — discard the outliers, then take off a negotiating margin of roughly 10%.
Another useful signal: time on the market. A listing that has been up for six weeks at the same price is telling you the price is 15 to 20% too high, not that the market is flat.
Depreciation by segment
Segments do not age at the same rate. Rough figures observed on the UK market:
| Segment | Loss at 1 year | Loss at 3 years | Floor |
|---|---|---|---|
| Entry-level city bike / hybrid | 40–50 % | 60–70 % | Very low |
| Mid to high-end carbon road | 30–35 % | 50–55 % | Steady |
| Full-suspension mountain bike | 30–40 % | 50–60 % | Steady |
| Gravel | 30–35 % | 45–55 % | Fairly firm |
| E-bike (all categories) | 35–45 % | 60–70 % | Depends on the motor |
| Cargo bike | 30–40 % | 50–60 % | Firm, thin supply |
Two different logics are at work. On high-end non-assisted bikes, depreciation mostly tracks how quickly drivetrain and braking standards go out of date. On e-bikes, it tracks the condition and remaining warranty of the battery — in other words a wear item worth £350 to £800.
On an e-bike, the motor counts for more than the badge on the frame
This is the most counter-intuitive lesson of the electric second-hand market: residual value depends far less on the name on the down tube than on the drive system and the ecosystem around it.
What holds a price up:
- A system with a dense service network and available spares. The buyer knows it can be diagnosed and repaired.
- A battery still under warranty, or recent, with a low cycle count that can be verified on a diagnostic.
- A standard display and diagnostic port that lets you read the true state of the system.
What crushes it:
- An orphaned drive system whose maker has gone under or no longer supplies parts.
- An integrated battery whose replacement pack costs more than half the value of the bike.
- Visible derestricting, which voids type approval and any insurance cover.
A four-year-old e-bike with a healthy battery and an active service network routinely sells for 20 to 30% more than an equivalent bike fitted with an orphaned motor.
