Free tools
Every Cyclesite tool, in one place
17 free tools for buying and selling used bikes in the UK. They run on live listings plus bikes that have recently sold or been delisted, matched by brand, model, year and condition. Prices throughout are advertised prices, not confirmed sale figures. Nothing here needs an account.

Where the numbers come from
Every price on this site is an advertised price. We read live listings across the UK market and bikes that have recently sold or been delisted, then match them on brand, model, year and condition. What a buyer finally handed over is not public information, so we do not claim to know it.
That makes these figures a reliable read on what bikes like yours are being asked for, and a good guide to what to list at. It is not a record of completed sales. Where there are too few comparable bikes to support a number, the tools say so rather than estimating one.
Common questions
Are these tools free?
Yes. Every tool on this page is free and none of them require an account. You can value a bike, check a frame number against stolen-bike records, size a frame or work out a gear ratio without signing up or giving us an email address.
Where does the pricing data come from?
From the UK used bike market itself: live listings across the marketplace and wider market, plus bikes that have recently sold or been delisted, matched by brand, model, year and condition. Prices are advertised prices. Cyclesite does not see what a buyer finally paid, so a sold bike is recorded at its last advertised price rather than a confirmed sale figure.
How accurate is a valuation?
A valuation is a read on what bikes like yours are being advertised for right now, not a guaranteed sale price. It is most reliable for common models with plenty of comparable listings, and least reliable for rare bikes, heavily modified builds and anything where the market is thin. Where there is not enough data to support a figure, the tool says so instead of estimating one.
How do I know if a bike is the right size?
Enter your height and inside leg into the size calculator. Sizing varies between manufacturers, so a Large from one brand can fit like a Medium from another: treat the result as the range to shortlist, then check the specific bike’s reach and stack against it. Riding one confirms what a calculator cannot.
What does the groupset tier actually tell me?
It tells you how the bike was specced when it was new, which is usually the clearest difference between two used bikes at a similar price. Higher tiers bring lighter materials and better shifting rather than a fundamentally different ride. The hierarchy page ranks the tiers within Shimano, SRAM and Campagnolo and lines them up against each other.
Can I use these tools on a bike that is not listed on Cyclesite?
Yes. The valuation, stolen check, size calculator, gear ratio calculator and listing price check all work on any bike, wherever it is advertised. The listing price check takes a link to an advert on another site and prices it against the same model across the UK market.
