How much is a used Decathlon bike worth? Rockrider, Triban, Van Rysel and Riverside

If there is one bike you see everywhere, in the village, on the greenway and in almost anyone's storage room, it is a Decathlon. Rockrider for the hills, Triban and Van Rysel for the road, Riverside for leisure rides and Elops for the city. Precisely because there are so many, looking for a second-hand Decathlon bike, or selling yours, has its tricks: there is plenty on offer, a new one is not expensive, and that puts a clear ceiling on the price of a used one. We show you where that ceiling is with bicis.net data.

The bicis.net benchmarks, and why Decathlon sits below them

These are the median asking prices on bicis.net by category. Use them as a rough ceiling, not as the price of a Decathlon: most of its models start from a lower new price than specialist-shop brands.

From Ciclismo en cifras: active «For sale» listings as of 30 October 2026, 218 in total. These are asking prices; the final price is usually a little lower.

In mountain bikes, the cheapest quarter asks for less than €450. That is where a mid-range hardtail Rockrider usually sits. Full-suspension models and carbon Van Rysels can get close to the median or go above it, but they rarely reach the upper quartile.

How to read the name of a Decathlon bike

Decathlon numbers its models, and the number tells you a lot about the price. Within each range, the higher it is, the better the build: a Rockrider ST 100 is entry-level, while an ST 540 or an XC 500 already have a lockout fork, hydraulic disc brakes and a better drivetrain. Always ask for the exact model and year, because the same number has changed components over the years.

Rockrider: mountain

The best-selling range. The ST models are for tracks and easy trails; the XC, for riding fast and racing; the AM and E-Feel, for descending with more travel. An entry-level ST sells for little because it costs little new; a carbon XC or a well-kept full-suspension bike does hold its value.

Triban and Van Rysel: road and gravel

The Triban is the entry-level road bike, comfortable and sturdy, and it also comes in gravel versions. Van Rysel is the high-end range, with carbon frames and race builds. A recent Van Rysel can get close to the road median; an aluminium Triban, stay well below it.

Riverside, Elops and the e-bikes

Riverside are hybrids for paths and greenways; Elops, city bikes. The electric versions of both ranges, and the Rockrider E-ST and E-Expl, are valued above all by their battery: with less usable capacity, the price drops a lot.

What to check on a used Decathlon

• The fork. On cheaper models it is a coil fork that cannot be serviced. Compress it hard: if it knocks or leaks oil, count on replacing it.
• Brakes. Mechanical or hydraulic makes a big difference. Squeeze the levers: they should feel firm and not reach the grip.
• Drivetrain and rust. Many Decathlons have spent their nights on balconies. Check the chain, cassette and bolts: surface rust cleans off, deep rust does not.
• Wheels. Spin them: they should have no side-to-side wobble or loose spokes.
• Battery, if it is an e-bike. Ask to see a full charge and how many cycles it has done or when it was bought.
• The receipt. Decathlon keeps purchases in the customer's account. Asking for the receipt or a screenshot is the easiest way to know the year and model, and that the bike belongs to the seller.

A fair price: sell or buy wisely

A practical rule: if a used Decathlon in good condition gets close to the price of the same bike new, it is not worth it. The new one comes with a warranty and the used one does not. To set your price:

• Raise it if it is high-end within its range (the high numbers, Van Rysel, XC), has hydraulic brakes, has been serviced and you still have the receipt.
• Lower it if it is entry-level, has rust, the fork is dry or parts are missing.
• Compare with what is listed right now in all bicis.net listings.

Selling it fast

Decathlons sell well because lots of people are looking for their first bike or one for everyday use. Put the range and number in the title («Rockrider ST 540, size M»). Clean the bike before taking photos and take one side-on, another of the drivetrain and another of the brakes. Say whether it has been to a workshop and whether you have the receipt. Listing on bicis.net is free.

Frequently asked questions

How much is a second-hand Rockrider worth?

It depends on the model number and condition. A mid-range hardtail Rockrider usually sits in the lower mountain-bike band: on bicis.net the cheapest quarter asks for less than €450, and the mountain-bike median is €813 (98 listings, data as of 30 October 2026).

Is a used Triban worth it?

Yes, for getting started on the road or for easy gravel, as long as the price is clearly below a new one and the drivetrain is healthy.

Can you check the year of a Decathlon bike?

With the receipt, which stays in the buyer's account, or with the model sticker on the frame. Ask for one of the two before you pay.

How do you value a Decathlon e-bike?

Mainly by its battery. As a benchmark, used e-bikes on bicis.net ask a median of €2,080 (48 listings, data as of 30 October 2026); a Decathlon one usually sits below that.
