How Much Is Your Bike Worth? A Real Valuation Guide (2026)

A few years back I nearly sold a bike for a third of what it was worth. Someone offered me £300 for it on Facebook Marketplace, I was tired, I said fine, and it was only after I'd handed it over that I found three completed listings for the same model in worse condition going for £480-£550. Lesson learned the expensive way: most people either wildly overvalue a bike because they remember what they paid for it, or wildly undervalue it because they can't be bothered to check.

There's no shortcut here. Anyone offering you an instant number by typing in your bike's brand and colour is guessing, and so is any calculator that spits out a price without asking what condition it's in or when you bought it. Bike valuation is more like valuing a used car or a guitar than reading a barcode — it takes a bit of digging, but it's not hard digging.

This is the method I actually use, whether I'm selling my own bike or telling a friend what theirs is worth before they take the first offer that comes along. It's a framework, not a magic number — plug in the specifics and you'll land within a sensible range.

Why bike resale value swings so much

Two bikes that cost the same new can be worth wildly different amounts a year later. A few things drive that:

• Brand demand. Brompton, Cannondale, well-known Dutch and German city brands hold value because there's a deep pool of buyers who specifically want that name. Own-brand or discontinued house bikes from big-box retailers often don't, no matter how good they actually are — nobody's searching for them.
• Condition, honestly assessed. Not "condition" as in how you feel about the bike — scratches, corrosion on the chain, cracked grips, a saddle that's gone shiny and hard. Buyers notice all of it and will use it to knock the price down, so you may as well knock it down first and price accurately.
• Age and how the model's aged. A three-year-old bike that's still the current model, or close to it, holds value better than a three-year-old bike that's been through two redesigns since. Check whether the manufacturer still sells something close to what you have.
• Original spec versus what's actually on it now. Upgraded a cheap groupset to something better? That adds value, but rarely pound-for-pound what you paid, because the buyer is buying your judgement, not just the parts. Downgraded or swapped components for worse ones to save a part for another bike? That subtracts more than you'd think.
• Groupset and component wear. A drivetrain (chain, cassette, chainring) wears out roughly together, and a stretched, worn one is an immediate deduction in a buyer's head, even if they don't say the number out loud. Wheels that are true and bearings that still feel smooth are worth mentioning explicitly in a listing, because their absence is what buyers assume by default.
• Whether it's electric, and what the battery's actually doing. This is the single biggest swing factor on a modern bike and it gets its own section below.

The step-by-step method

Work through these in order. Skipping steps is how you end up either giving your bike away or sitting on it for six months because you priced it like new.

1. Find your exact model and year. Not "a Trek hybrid from a few years ago" — the actual model name and, if you can find it, the frame size and model year. Check the frame for a sticker, look up the serial number if you're stuck, or dig out the original receipt or box. This one step removes most of the guesswork in everything that follows.
2. Check what it sold for new. Search the manufacturer's site (they often keep old model pages live or archived), or search "[model name] [year] RRP" and cross-check a couple of results. This is your ceiling, not your price — nobody pays retail for a used bike, however good the story.
3. Check real, recent, completed sales — not asking prices. Asking prices are aspiration. Sold prices are reality. On eBay UK, search your model then filter to "Sold items" (under the Show only heading in the left-hand filters) — that shows what people actually paid, not what sellers hoped for. Do the same search on Facebook Marketplace by browsing similar listings and noting how long they've been up (a listing sitting for eight weeks unchanged tells you the price is wrong). BikeExchange lists used bikes with asking prices, useful for a second reference point. For anything higher-end or mountain bike specific, The Pink Bike Buysell forum is the closest thing cycling has to a proper secondhand market — enthusiasts pricing enthusiast bikes, and they know exactly what things are worth.
4. Adjust for condition and upgrades. Take the middle of the range you've found from sold listings, then move up or down based on the honest condition assessment from the section above. A tidy, well-maintained bike with documented servicing can sit near the top of the range. One with visible wear, a tired drivetrain, or an "it just needs a new tube" that's actually needed one for a year should sit near the bottom.
5. Adjust for battery health if it's electric. Don't skip this — see the next section. A tired battery can take 20-30% off the price a healthy one would fetch, even if everything else about the bike is mint.
6. Decide: price to sell, or price to wait. If you want it gone this week, price at or slightly below the bottom of your range and say so in the listing ("priced to sell, no time-wasters"). If you're not in a rush, price near the top and expect it to sit for a few weeks while you field a couple of lowball offers. Both are legitimate strategies — just pick one on purpose rather than drifting into a bad version of either.

Rough condition guide: percentage of original RRP

These are sensible ranges based on how the secondhand market generally behaves, not a scientific formula — treat them as a sanity check against what you find in step 3, not a replacement for it.

Condition	Typical age	% of original RRP
Excellent, barely ridden	Within 1 year	70-80%
Very good, light wear, well maintained	1-2 years	55-65%
Good, normal wear, serviced occasionally	2-4 years	40-55%
Fair, visible wear, needs some attention	4-7 years	20-35%
Well used, needs parts or a service to be rideable	7+ years	10-20%

Desirable brands and models that are hard to find secondhand can sit above these ranges. Own-brand or discontinued models can sit below them, sometimes well below, regardless of how well they've been looked after — that's demand talking, not a judgement on the bike.

The e-bike battery problem

An e-bike is not just a bike with a motor bolted on, and it doesn't resell like one. The battery is a consumable with a finite number of charge cycles, and unlike a worn chain, you can't just swap it for £15 — a replacement battery can cost several hundred pounds, sometimes close to what a budget analogue bike costs outright.

A few things that tank e-bike resale value faster than a normal bike's components wear out:

• Cycle count and age matter more than mileage. A battery charged daily for two years has been through far more degradation than one ridden the same distance but charged less often. If you can check the battery health via the manufacturer's app (many brands now show this), do it and include the number in your listing — it builds trust and headers off the inevitable question.
• Range anxiety is a resale killer. A buyer comparing a two-year-old e-bike to a brand-new one isn't just weighing price — they're weighing "will this still get me to work and back on one charge in a year's time." If your honest answer is "probably not," that's reflected in what people will pay, and no amount of polishing the frame changes it.
• Proprietary batteries hurt more than universal ones. A bike using a common, still-in-production battery format is easier to sell than one with a discontinued, brand-specific battery that's hard to source a replacement for. If you're not sure which yours is, it's worth checking before you list.
• Be upfront about it. Trying to sell an e-bike without mentioning battery health is the fastest way to get lowballed once a buyer asks — and they will ask. State the age, the approximate cycle count if you know it, and the last time it was serviced. It reads as honest rather than as a red flag.

As a rough rule, expect an e-bike to depreciate 5-10 percentage points faster than the same category of analogue bike at the same age, purely because of the battery question sitting over every sale.

Where to actually sell it

• eBay — biggest audience, auction or fixed price, and the "sold listings" filter doubles as your research tool from step 3.
• Facebook Marketplace — no fees, local buyers, good for a fast sale, but expect more lowball messages than on eBay.
• BikeExchange — cycling-specific audience who already know what they're looking at, which cuts down on time-wasting questions.
• Pink Bike Buysell — the place for higher-end road and mountain bikes, where the buyers genuinely know component groups and will pay fairly for a bike that's been looked after.
• Local bike shop consignment — some shops will sell on your behalf for a cut, usually 15-25%. Less money in your pocket, but zero hassle, no time-wasters, and someone else fields the questions.

And if you're selling because you're upgrading rather than just cashing out, it's worth a browse of what's currently in the shop before you commit to a like-for-like replacement — sometimes the bike you actually want is a different category entirely, not just a newer version of the one you've got.

The verdict

Here's what I'd tell a friend standing in their hallway wondering what their bike's worth: don't trust a single number from a single source, and don't trust your own memory of what you paid for it. Find the exact model, check three or four real completed sales, be brutally honest about condition and — if it's electric — about the battery, and you'll land on a fair price within about ten minutes of actual work. Anyone who tells you it's more precise than that is selling you something.
