With 5 folding bikes currently listed on Cyclesite and an average asking price of £334, the under-£750 segment is one of the most varied — and genuinely useful — corners of the used cycling market. Prices span from £150 for a fair-condition 2022 steel folder up to £675 for a 2004 Brompton 6-speed, which tells you something important: this budget covers everything from a no-frills commuter to a genuinely iconic machine with serious resale legs of its own.
Folding bikes have earned their place beyond the 'novelty' category. For anyone navigating mixed-mode commutes — train to office, bus to campus, cab to meeting — a folder that actually fits under your desk or in an overhead rack is a practical tool, not a compromise. The question is which compromise you're willing to make: weight, fold speed, ride quality, or price.
What's interesting about this market right now is the mix of technologies on offer. You'll find traditional steel-framed folders sitting alongside 2024-spec aluminium electric folders, all within the same £150–£675 window. That range reflects wildly different propositions, and buying blind without understanding the differences is how people end up disappointed.
This guide breaks down what to look for when buying a folding bike under £750, what the real trade-offs are at different price points within that range, which brands are worth your attention based on what's actually listed, and how to avoid the common mistakes that turn a smart purchase into a frustrating one.

Buying Guide
The first thing to understand about buying a folding bike under £750 is that the median asking price on Cyclesite is £275 — meaning half the market sits below that figure. That's genuinely useful context, because it tells you a sub-£300 purchase is entirely normal here, not a sign you're scraping the bottom of the barrel.
Frame material matters more on folders than on regular bikes. Steel frames — like the 2022 folder listed at £150 and the 2004 Brompton at £675 — are heavier but more forgiving of rough roads and, critically, more repairable. If a weld cracks on a steel frame, a decent bike shop can fix it. Aluminium frames, like the 2024 DYU D3F listed at £320, are lighter but less forgiving of stress fractures, which is worth knowing if you're folding and unfolding daily.
Fold mechanism quality is everything. A folder that's stiff, fiddly, or requires two hands and a prayer to close will simply stop being used. Before buying, ask the seller to demonstrate the fold on video if you can't view in person. Hinges and latches should engage positively with no wobble.
Wheel size shapes the ride character significantly. The 14-inch wheels on the DYU D3F and the DVU 14-inch folder (listed at £275) make for an extremely compact fold but require more steering input and feel skittish on poor road surfaces. Brompton's 16-inch wheels split the difference reasonably well.
For electric folders specifically — and the DYU D3F at £320 is the only e-folder currently listed — battery condition is the critical unknown. Ask for charge cycle history if available, and factor in that a replacement battery can cost £100–£200 depending on the model. A £320 e-bike with a degraded battery is a different proposition entirely.
At the top of this budget, the 2004 Brompton 6-speed at £675 is worth discussing separately. Bromptons hold value extraordinarily well and are genuinely superior folders in terms of fold compactness and ride quality. A 2004 model in good condition is a legitimate buy — Brompton parts remain available and the design has barely changed. You're paying for heritage and practicality, not just a name.
Avoid buying any folder without checking the hinge clamps for play, the tyres for cracking (especially on older bikes), and the gearing mechanism for smooth shifting. On small-wheeled bikes, even minor brake adjustment issues become noticeable quickly.

Market Insights
The folding bike segment under £750 on Cyclesite is compact but genuinely diverse, with 5 active listings spanning a price range of £150 to £675. The average asking price of £334 sits notably above the £275 median, pulled upward by the Brompton at £675 — remove that outlier and the market centres closer to £270. Brompton dominates the premium end of this budget, while newer entrants like DYU and DVU occupy the mid-range with aluminium-framed and electric options. Fiido rounds out the e-bike representation at £250. Condition skews positive — three of the five listings are described as Excellent — suggesting sellers in this segment are typically offloading bikes that have been lightly used rather than ridden into the ground.
Frequently Asked Questions
What is a reasonable price to pay for a used folding bike in the UK?
Based on current Cyclesite listings, the median asking price for folding bikes under £750 is £275, with an average of £334. The range runs from £150 for a fair-condition steel folder up to £675 for a Brompton. In practice, £250–£350 gets you a solid used folder in excellent or good condition, while anything below £200 warrants closer inspection of the fold mechanism and frame.
Is a Brompton worth buying used?
Yes, with caveats. The 2004 Brompton 6-speed listed at £675 on Cyclesite is a good example of why Bromptons hold value: the design is largely unchanged since the early 2000s, parts remain widely available, and the fold is genuinely class-leading in compactness. Check hinge wear and tyre condition on older models. A well-maintained Brompton at this price point is a legitimate long-term investment.
Are electric folding bikes under £750 worth considering?
They can be, but battery condition is the critical variable. The DYU D3F listed at £320 on Cyclesite is a 2024 model in excellent condition with aluminium construction, which is a reasonable proposition. On any used e-folder, ask about charge cycles and test the battery range before buying. Replacement batteries for budget e-bikes typically cost £100–£200, which can significantly alter the effective purchase price.
What wheel size is best for a folding bike?
It depends on your priorities. The 14-inch wheels on bikes like the DYU D3F and the DVU 14-inch folder create a more compact fold and lighter overall package, but they're more sensitive to road surface and require more active steering. Brompton's 16-inch wheels offer a slightly more stable ride. If your commute involves rough roads or longer distances, larger wheels will feel noticeably more comfortable.
What should I check before buying a used folding bike?
Focus on the fold mechanism first — hinges and clamps should engage firmly with no lateral play. Check the tyres for cracking or flat spots, especially on older models. Test the gears through all positions and squeeze both brakes firmly. On steel-framed bikes, look around welds for rust. On electric models, confirm the battery charges and holds charge. If buying remotely, ask for a short video of the bike being folded and ridden.
Which folding bike brands are best for commuting?
Among the brands currently listed on Cyclesite in this segment, Brompton has the strongest reputation for commuter use — the fold is fast and compact enough for tube and train travel. DYU and Fiido offer electric assistance which suits longer or hillier commutes. DVU and generic steel folders are better suited to shorter, flatter routes where weight and fold speed matter less.
How do the best folding bikes under £750 compare to spending more?
The best folding bikes under £750 cover a surprisingly wide range of quality and technology. Spending more — typically £800 and above new — gets you lighter materials, faster fold mechanisms, and better component quality. However, the used market complicates this: a £675 Brompton in good condition often outperforms a brand-new £400 folder in real-world commuting terms. Within this budget, the gap between a £150 and a £500 purchase is substantial.
