Discover a new generation of folding bikes that combines compact portability, innovative frame engineering and the freedom to explore beyond the city streets.
What if your folding bike could do more than simply get you from A to B?
Introducing the new DAHON LUNDEN 20-inch, a 2026 model that brings a fresh approach to folding-bike design. Developed for riders who want practical everyday transport without giving up comfort, stability or versatility, the LUNDEN combines DAHON's latest frame technology with wide tyres, adjustable ergonomics and a compact tri-fold design.
Whether you're commuting to work, cycling along canal paths, exploring country lanes or looking for a practical bike to take on your travels, the LUNDEN offers an exciting new option for modern cyclists.
A New Generation of Folding Bike
Folding bikes have always offered an obvious advantage: they are easier to store and transport than conventional bicycles. But portability alone does not guarantee an enjoyable ride.
Frame stiffness, handling, tyre width and riding position all make a difference, especially when the road becomes uneven.
The DAHON LUNDEN 20-inch has been designed to address these challenges. Its completely redesigned frame connects the head tube directly to the bottom bracket, while reinforced seatstays help improve structural rigidity and stability.
The result is a folding bike engineered to deliver efficient pedalling, confident handling and a more responsive riding experience.
DAHON-V Tech and the Patented DELTECH System
One of the LUNDEN's most interesting features is DAHON's proprietary DAHON-V technology, including its patented DELTECH system.
Traditional folding-bike frames must balance two competing priorities: they need to fold conveniently while remaining sufficiently rigid when ridden.
DELTECH adds a structural cable that works with the frame to create a more stable triangular structure. According to DAHON, this arrangement can increase frame rigidity by approximately 15%.
Why does that matter to everyday riders?
A stiffer frame can help reduce unwanted flex when pedalling, allowing more of your effort to contribute to forward motion. It can also contribute to a more controlled, confident feeling when accelerating or riding over uneven surfaces.
For a folding bike designed to go beyond short urban journeys, this focus on frame engineering is particularly relevant.
Compact When Folded, Versatile on the Road
The LUNDEN uses a practical tri-fold design that makes it easier to store and transport when you're not riding.
According to DAHON, the 20-inch model is approximately 12% smaller than conventional 20-inch folding bikes. Its published folded dimensions are approximately 74 × 40 × 70 cm, making it a useful option for homes with limited storage space, offices and car boots.
It is also worth considering for journeys that combine cycling with other forms of transport. You can ride to your destination, fold the bike for storage and enjoy greater flexibility in how you travel.
At approximately 15.1 kg, it is not an ultra-lightweight folding bike, but its compact folded format offers a practical balance between portability and a more substantial riding platform.
20-Inch Wheels and Wider Tyres for More Freedom
Not every journey takes place on perfectly smooth tarmac.
The DAHON LUNDEN features 20-inch wheels with 2.0-inch-wide multi-terrain tyres. The wider tyre profile offers a useful balance of traction, cushioning and stability for everyday cycling.
This makes the bike suitable for a variety of environments, including:
Urban streets and daily commutes.
Uneven pavements and patchy road surfaces.
Canal paths and recreational cycling routes.
Light gravel tracks and suitable country paths.
The LUNDEN is not a replacement for a dedicated mountain bike, but its design makes it an appealing option for riders who want more flexibility than a conventional city-focused folding bike can offer.
Adapt Your Ride to the Road
Comfort is not only about the saddle or tyres. The way a bicycle responds to changing surfaces can also make a noticeable difference.
The LUNDEN series features DAHON's Dynamic Suspension System, designed to let riders adjust damping according to road conditions. This allows a balance between efficient pedalling on smoother surfaces and improved impact absorption when the route becomes rougher.
The 20-inch model also features a system described by DAHON as a “Hard & Soft Tail” adjustment, providing different rear-end riding characteristics.
Combined with the adjustable handlebar stem, these features give the LUNDEN a more adaptable riding setup for changing routes and individual preferences.
Comfort That Fits the Rider
A good bicycle should work with your body, rather than force you into an uncomfortable position.
The LUNDEN features an adjustable handlebar arrangement that allows riders to fine-tune their riding position. Its multi-segment adjustable seatpost is designed to provide further ergonomic adjustment.
This flexibility is useful for everyday commuting and recreational rides, where comfort and control matter just as much as speed.
DAHON lists a rider-height range of approximately 4'7" to 6'2" (140–188 cm) for the LUNDEN 20-inch, although individual fit will depend on proportions and preferred riding position.
Practical Components for Everyday Cycling
The LUNDEN's appeal is not limited to its frame and folding mechanism. Its component specification also makes it worth considering as an everyday bicycle.
Shimano 8-speed drivetrain: offers a range of gears for commuting, changing gradients and recreational riding.
Tektro hydraulic disc brakes: provide hydraulic braking control and are a useful feature for riders who regularly encounter wet-weather conditions.
Adjustable handlebar stem: helps riders tailor the cockpit position to their needs.
Quick-release pedal: contributes to the bike's space-saving design when folded.
Together, these features create a versatile package for cyclists who want one bicycle to cover a range of everyday journeys.
Who Is the DAHON LUNDEN 20-Inch For?
The LUNDEN could be a particularly good fit for:
Urban commuters who need a practical bike that can be folded for storage at home or work.
Car owners who want to keep a bicycle in the boot for spontaneous rides and weekend trips.
Leisure cyclists who enjoy exploring parks, canal paths and light gravel routes.
Space-conscious households looking for a full-featured bicycle that occupies less storage space when not in use.
Cyclists looking for something different who appreciate innovative engineering and the convenience of a tri-fold design.
If you want a bicycle that folds away conveniently but is still designed for varied riding conditions, the LUNDEN deserves a closer look.
