DAHON LUNDEN Aims to End the Performance Compromise in Folding Bikes

CHICAGO, IL – February 10, 2026 – Folding bike pioneer DAHON today launched its new LUNDEN series, a line of tri-fold bikes engineered to solve one of the category's most persistent challenges: the trade-off between portability and performance. By integrating its proprietary DAHON-V Tech into a tri-fold design for the first time, the company claims to have created a bike that delivers the stiffness and ride quality of a full-size frame in a package that folds for the modern commuter.

The announcement comes as the folding bike market, valued at over $725 million in 2024 and projected to grow at a CAGR of over 9%, sees a distinct shift. As rider expectations evolve, the focus is moving from pure price competition toward engineering-led differentiation. DAHON's LUNDEN series, which received an enthusiastic reception from dealers at its recent CABDA Midwest debut, positions the company squarely at the forefront of this performance-oriented transition.

Redefining Rigidity in a Compact Frame

For years, the appeal of tri-fold bikes has been their incredible portability. However, this convenience often comes at a cost. The multiple hinges and single-beam frames inherent to many compact designs can lead to a lack of structural stiffness, resulting in frame flex. This flex dissipates the rider's energy, reducing power transfer to the wheels and creating a less stable, sometimes "wobbly" ride, particularly during acceleration or climbing.

DAHON aims to eliminate this compromise with DAHON-V Tech, a suite of patented technologies developed over thousands of hours of research and development. The LUNDEN series incorporates two key innovations to bolster its frame: DELTECH and the Super Down Tube.

The DELTECH system introduces a high-tension cable that connects the front of the main tube to the bottom bracket area, effectively transforming the single tube into a rigid triangular structure. DAHON claims this simple but powerful addition increases frame strength by up to 15%, dramatically improving stability and power transfer. It also reduces stress on the folding hinge, a critical component, thereby enhancing the frame's durability and lifespan.

Complementing this is the Super Down Tube, which features a larger diameter tube that is flattened at its connection points. This design significantly increases the coupling strength between the main structural elements of the bike. According to company data, this feature alone boosts vertical and horizontal rigidity by over 10%. When combined, these technologies promise a ride that is not only more efficient but also instills greater confidence in the rider, whether navigating busy city streets or tackling rolling hills.

Two Models for Two Missions: The LUNDEN Lineup

Recognizing that urban riders have diverse needs, DAHON is launching the LUNDEN series with two distinct models, each optimized for different use cases but built on the same foundation of performance.

The 16-inch LUNDEN is engineered for maximum portability and agility. Its compact and lightweight design is ideal for "last-mile" commuting, where the bike is frequently folded, carried onto public transport, or stowed under a desk. While prioritizing ease of use with a streamlined drivetrain, it doesn't skimp on performance, integrating both the DELTECH cable and Super Down Tube to ensure a solid and responsive ride for short-distance maneuvering.

For riders seeking greater versatility, the 20-inch LUNDEN offers a completely redesigned frame built for what DAHON calls "extreme rigidity." It features a direct linkage between the headtube and the bottom bracket, along with a strengthened seatstay, creating an exceptionally stable platform for higher speeds and more demanding conditions. Equipped with wide 2.0-inch tires, this model is adept at handling everything from smooth asphalt to uneven pavement and even light gravel paths. Despite its larger wheels and robust build, its folded size is 12% smaller than conventional 20-inch folding bikes, striking a new balance between capability and convenience.

Both models in the series also feature an innovative Dynamic Suspension System, allowing riders to make quick, on-the-fly adjustments to the damping based on road conditions. This enables a balance between firm pedaling efficiency on smooth surfaces and impact absorption on rougher terrain. Rider comfort is further addressed with a multi-segment adjustable seatpost that allows for precise micro-adjustments in both height and angle, ensuring an optimal ergonomic fit for a wide range of body types.

A Strategic Pivot in a Crowded Market

The launch of the LUNDEN series is more than just a new product release; it represents a calculated strategic move in the increasingly competitive folding bike market. While brands like Brompton have long dominated the ultra-compact segment with their iconic 16-inch wheel designs and premium lightweight models, and Tern has earned a reputation for the stable, smooth ride of its larger-wheeled folders, DAHON is carving out a new space focused explicitly on high-rigidity performance.

This move taps into a growing segment of consumers who are no longer willing to accept a significant performance penalty for the convenience of a folding bike. As market analysts noted in the company's release, "DAHON's recent technical advances are prompting renewed attention to frame stiffness, drivetrain efficiency, and real-world ride performance." The industry appears to be maturing, with a clear demand for premium products that deliver a superior riding experience.

The LUNDEN 20-inch, with its larger wheels and mixed-terrain capabilities, enters as a direct challenger to models like Brompton's recently introduced G-Line, which also uses 20-inch wheels to court adventure-focused riders. However, DAHON's emphasis on its proprietary V-Tech rigidity solutions as the core differentiator could give it a unique selling proposition in a market where ride feel is paramount.

Innovation Backed by Market Momentum

DAHON's ambitious push into the performance tri-fold segment is underpinned by significant corporate and financial momentum. The company, which holds the top market share in China's folding bike sector, recently completed a highly successful IPO on the Hong Kong Stock Exchange that was oversubscribed more than 7,500 times. With revenues climbing 50% in 2024 to over $63 million and plans for major manufacturing expansion, DAHON is investing from a position of strength.

This focus on engineering is not new for the company, which holds over 135 active patents. By licensing its technology to other brands through its "Sharing 360" program, DAHON is signaling its confidence that its innovations can set a new industry standard. The widespread acclaim from dealers at the CABDA Midwest trade show for the LUNDEN 20-inch provides early validation that the industry is receptive to this performance-first approach. As the LUNDEN series rolls out to consumers, the broader market will decide if DAHON has truly cracked the code on delivering full-size performance in a tri-fold package.
