Decathlon has launched an Autumn BuyBack Bonus, offering an extra 20% on the in-store trade-in value of any bike, valid from now through Sunday, 2 November 2025. Framed as a pre-Christmas push for families, the “Decathlon bike trade-in” offer issues a Decathlon gift card once the bike is assessed in store. Any brand can be traded in, and the bonus sits on top of the usual BuyBack valuation.
The incentive is tied to Decathlon’s Second Life programme, which refurbishes and resells used products. According to the company, refurbished Second Life bikes now account for 10% of all bike sales, while 5,900+ items have been traded in so far in 2025—more than double last year’s total. During this year’s Easter promotion, over 1,000 items were returned. “By offering a bonus on our BuyBack scheme, we’re helping parents fund a new gift while pre-loved bikes get a second life,” said Chris Allen, Sustainability Leader at Decathlon UK.
How the Decathlon bike trade-in works
The process is straightforward. Customers need to be Decathlon members (registration is free). You begin with an online estimate and book an in-store appointment, where Decathlon staff assess the bike. If accepted, a digital gift card will be issued with an additional 20% bonus included. The promotion covers bikes of any brand and aims to make upgrading easier—whether that’s moving a child up to the next wheel size or simply clearing out a shed before the festive season. The company pitches it as both a wallet-friendly option and a circular-economy boost that keeps serviceable bikes in use rather than heading to waste.
Why it matters for family cycling (and e-bike curious parents)
Trade-in promotions are often the nudge households need to move to a more suitable bike, especially for growing kids. For families considering a switch to utility cycling, a Decathlon bike trade-in can free up budget for equipment that broadens what a bike can do on a day-to-day basis. Suppose you’re weighing up school-run practicality or a car-lite routine. In that case, our guide to the best electric cargo bikes breaks down front-loader and longtail formats, capacities and everyday usability. For a narrower focus on parent-friendly handling and storage, see longtail cargo bikes: 2025’s best family-friendly options.
Not every family needs a cargo platform from day one. If you’re keeping a conventional bike in the mix, a child-carrying kit can bridge the gap. Our latest group test of the best child and baby seats for bikes covers fit, mounting standards, and what to look for as your child grows. Meanwhile, this primer answers a common question: Do I need a cargo bike to transport kids?
If the plan is to step into e-bikes for commuting or school runs after trading in, we’ve rounded up the best electric bikes under £2,000 and the best cheap electric bikes to show what’s realistic at lower price points. And if you’re new to the category, our explainer on UK e-bike rules and regulations clarifies what’s road-legal—practical context if you’re comparing options on the shop floor.

Environmental angle without the spin
Decathlon’s pitch leans on reuse over disposal: bikes traded in are prepared for resale, and the gift-card-based bonus nudges riders to keep spending within the ecosystem. For parents, the attraction is practical—turning an outgrown bike into credit for a new child’s model or towards a utility kit that makes cycling a viable option. For the market, the Second Life channel helps keep entry prices in check for those who prefer to buy refurbished. The fact that Second Life bikes now account for a tenth of Decathlon’s bike sales underscores a maturing recommerce loop in mainstream retail.
