Comparing used bike prices: how to tell if a listing is fairly priced

You've spotted a bike that suits you and the price looks good. But is it? Glancing at two other random listings isn't enough: you need to compare bikes that are genuinely alike and set them against a benchmark. This guide is for you, the buyer: what to compare, what prices people are asking on bicis.net today and which signs tell you a price is too good to be true.

What to compare so the comparison counts

Two mountain bikes can differ in value by double and both still be fairly priced. What changes the price isn't the word «mountain», but what lies underneath. Before comparing used bike prices, gather listings that match on these five things:

• The exact type. An entry-level hardtail isn't the same as a full-suspension trail bike, nor is an aluminium road bike the same as a carbon aero one. Compare within the same family.
• The year or generation. A model changes a lot from one generation to the next: rim or disc brakes, external or integrated cables, geometry. Ask for the year if the listing doesn't say.
• The groupset and components. Gears, brakes, wheels and fork move the price more than the frame. Two identical bikes with different groupsets are not the same bike.
• The size. A size that fits you is worth more to you than a cheaper one you can't use. And the most common sizes sell first, so their prices hold up better.
• The condition. Kilometres, knocks, servicing and replaced parts. A bike with a new drivetrain and serviced suspension justifies asking more.

Once you have three or four listings that match on almost everything, the average price of that group is your best benchmark. If you can't find bikes that similar, use the medians below as a starting point.

The prices being asked on bicis.net today

This table comes from the active «For sale» listings on bicis.net. It's what sellers are asking, not the final sale price: deals often close a little below. The lower and upper quartiles show you where the middle half of the listings sits.

Data as of 5 November 2026, based on 223 active listings (bicis.net, «Ciclismo en cifras»).

How to read it: if a mountain bike is listed at €850, it's right in the middle. If it's below €450, it's among the cheapest there are: it may be a basic bike or a bargain, but take a calm look. If it's above €1,400, it's among the pricey ones and should have a build or condition that explains it. In road bikes the gap between the lower and upper quartile is huge, because entry-level aluminium bikes sit alongside high-end carbon ones: there, compare even more strictly within the same family.

How to tell if a listing is fairly priced, step by step

1. Give the bike a full name

Brand, model, year, size and groupset. If the listing doesn't say, ask before anything else. A seller who knows their bike will answer in a minute.

2. Find its twins

Look for the same model, or an equivalent one, with a similar year and groupset. Note down their prices. With three or four you already have a range.

3. Run it through the valuer

The bicis.net bike valuer gives you a benchmark in seconds using the bike's details. Use it as a second opinion, not as gospel: you only see the real condition in person.

4. Adjust for condition

Subtract what you'll need to replace soon: a worn chain and cassette, brake pads, tyres, a suspension service. Add if it comes with better parts than stock. The fair price for you is the listed price minus what it will cost you to get it ready to ride.

5. Negotiate with data

If the price is above its twins, say so politely and with numbers: «I've seen three similar ones for less». It works better than haggling for the sake of it.

Signs the price is too low

Bargains exist, but a price well below the lower quartile for its type deserves a second look. Be wary if several of these signs come together:

• A high-end bike practically given away, with a rush to sell it.
• There's no receipt and the seller can't tell you where the bike came from.
• The frame number has been erased or filed off, or the seller won't show it.
• They only want to meet in odd places or ask for payment upfront without you seeing the bike.
• The photos look like they're taken from a catalogue or another listing.

Before paying, check the frame number in the bicis.net stolen bikes register. It's free, takes a moment and saves you a nasty surprise. If something doesn't add up, keep looking: there are more bikes out there.

What to check by bike type

Each type has its weak points, and knowing them helps you compare prices with good judgement:

• Mountain: fork, shock, bearings and linkages. Unserviced suspension can eat up the price difference. You'll find it all in the guide to buying a second-hand mountain bike.
• Road: the frame (especially if it's carbon), the groupset and the wheels. Look carefully at the head tube and bottom bracket area. More details in the guide to buying a second-hand road bike.
• E-bikes: the battery rules. Ask about charge cycles or the health the system reports, and the motor's kilometres. A tired battery knocks a lot off the bike's real value.

And if you'd rather sell yours than buy, there's the guide to how much your second-hand bike is worth, designed to help you price your listing.

Frequently asked questions

How much does a second-hand bike cost on average?

It depends on the type. On bicis.net, as of 5 November 2026, a used mountain bike is listed at a median of €850, a road bike at €1,150 and an e-bike at €2,160. These are asking prices, not final sale prices.

How do I compare used bike prices reliably?

Only compare bikes of the same type, year, groupset, size and condition. Gather three or four very similar listings, look at their average price and check it against the median for their type and against the bicis.net valuer.

When is the price of a used bike suspicious?

When it's well below what similar bikes are listed for and, on top of that, there's no receipt, the frame number isn't visible or there's a rush to get paid. In that case, check the frame number in the stolen bikes register before paying.

Can you negotiate the price of a second-hand bike?

Yes, and it's normal. What works best is negotiating with data: the prices of similar bikes and what it will cost you to get it ready to ride.
