The Cyclesite Retail Price Index provides a monthly overview of the UK used-bike market, drawn entirely from completed transactions on our marketplace.
Published monthly, our RPI provides an overview of the latest pricing data from our marketplace and across the used-bike market.
Our team of data scientists track tens of thousands of completed sales each month, covering road, mountain, gravel, e-bikes, hybrid, folding and cargo categories. Coupled with data from active listings every day, this ensures the index is an accurate reflection of the live retail market.
The methodology is designed to mirror Autotrader’s published RPI. We report the mean asking price across every advertised and recently-delisted listing in the category, with upstream outlier scrubbing (MAD) to prevent single spikes distorting the series. Categories with fewer than 10 observations in a period are excluded, and no index point is published on thin data.
The resulting series gives journalists, retailers and riders a reliable, independent benchmark for how used-bike values are moving in the UK. Be sure to check our commentary below for more insight.

Methodology
Every data point comes from an advertised or recently-delisted listing across the UK used-bike marketplaces we track. Asking-price data reacts faster than confirmed-sold and is what buyers actually see, so it is the same signal Autotrader’s RPI publishes.
The headline is the mean asking price, matching Autotrader’s convention. We compute the median alongside and surface it if the two diverge, so a single spike never becomes the story.
Categories with fewer than 10 sales in a period are excluded. No index point is published on thin data.
Use the condition and price-band filters for stock-mix-adjusted comparisons. This removes the noise of different bikes entering and leaving the market.
Auctions, trade-ins, and incomplete transactions. Only clean, verified sales contribute to the index.
Indices are recomputed at the start of each calendar month. The next update is due next month.

FAQ
We track the average advertised (asking) price of used bikes in each category across UK marketplaces. The earliest data point equals 100. A reading of 105 means average advertised prices are five percent higher than that baseline. Using the mean of asking prices mirrors the convention used by established retail price indices like Autotrader.
Used bikes advertised for sale across every UK marketplace we track. We exclude retailer RRPs, trade-in quotes, and listings under £50 so the series reflects genuine used-bike asking prices rather than new-bike pricing or parts.
Monthly. Indices are recomputed at the start of each calendar month covering the previous period.
Price shows the actual mean asking price in pounds. Index normalises to a baseline of 100, making it easy to compare relative movement across categories. Change % shows the month-on-month percentage movement.
Yes. Use the advanced filters to see how prices move within specific segments, for example only Excellent condition bikes, or only bikes in the £1,500-£3,000 range.
Supply and demand vary. Gravel bikes spike in spring. E-bikes hold steady year-round. Mountain bikes dip in winter. New model releases affect specific categories. Each market has its own dynamics.
