As the pandemic comes to an end, many people have started to embark on revenge travel, especially to Japan. Due to the depreciation of the yen, prices are very favorable for Hong Kong residents. Additionally, certain Japanese brands are hard to find in Hong Kong, attracting a large number of travelers to Japan for shopping sprees. Bicycles, particularly a model known as the Dahon K3+ Japanese version — the K9X — have become a popular choice for bike enthusiasts to photograph and share. However, many bike enthusiasts are torn about whether they should purchase this bicycle.

The hesitation to purchase a bicycle stems not only from concerns about rising storage fees but also primarily from the price, which converts to about HKD 7,000. The last purchasing experience left me feeling unsatisfied, as I spent more money and had to struggle to bring it back myself, which really wasn’t worth it. In contrast, it seems more reasonable to set aside some budget for enjoying delicious food, like Omakase. Moreover, Hong Kong has finally introduced the K9X recently.

In this episode, I will provide a detailed comparison between the K9X and the K3+, analyzing whether this bicycle is worth buying. For those interested in these details, make sure not to miss it—be sure to watch until the end!

In-Depth Introduction to the Dahon K3+Japanese Version K9X

In this episode, we will introduce the 16-inch Dahon K3+ Japanese version—theK9X. It's important to note that this bike is not just a simple color variation; it boasts its unique Japanese identity. The packaging clearly indicates "Shipped to Osaka," making it a legitimate Japanese version.

The K9X and K3+ have many differences, both big and small, that are worth exploring. First and foremost, the color options are a highlight of this Japanese version. The K9X is no exception, offering two color choices: "Matte Black Gray" and "Matte Green."

The frame's center and the rear fork on both sides feature an "X" mark, showcasing a mysterious and distinctive style that makes the overall design even more appealing.

Next, we will dive into an in-depth analysis of the various features of this bicycle, helping you determine whether it meets your needs.

Notable Design Differences Between the K9X and K3+

In terms of design, the K9X and K3+ exhibit significant differences, particularly in the design of the head tube. Over the past two years, the K3+ has utilized an adjustable head tube, while the K9X features a fixed-height head tube.

Although this design reduces some flexibility for adjustments, it also decreases the overall gaps in the frame, making the structure more stable and providing a better feel when lifting the bike. This design is similar to that of the Little Buddy's head tube, which cannot be raised or lowered, but each design has its own supporters.

Additionally, the K9X features adjustable handlebar angles, providing more flexibility compared to the fixed setup of the Little Buddy. This adjustability allows riders to customize their riding position, enhancing comfort and control during rides.

Another noticeable design change is the internal cable routing. In the K9X, the cables run along the right side of the frame and extend along both sides of the rear fork, creating a smoother and more natural appearance.

In contrast, the previous K3+ version had these cables routed along the outer lines, which garnered some feedback from cyclists regarding the design. It remains to be seen whether the internal cable design of the K9X will meet their expectations.

Unique Accessories of the K9X

In terms of accessories, the K9X showcases distinctive features. This bicycle is equipped with a one-sided quick-release pedal from MKS, a top brand in the world of quick-release pedals, with all products manufactured in Japan.

Additionally, the K9X has seen an upgrade in its brake system, replacing the previously used Dahon-branded brakes with Tektro calipers. While the functionality remains largely unchanged, this brand upgrade provides a psychological boost for riders, instilling a sense of enhanced quality and reliability.

However, the brake levers on the K9X still utilize Dahon's proprietary design. This continuity ensures compatibility with the bike's existing systems while maintaining a familiar feel for riders accustomed to Dahon's products.

Another detail worth noting is the presence of several screws at the "pig nose" section at the front of the K9X, which are covered by caps featuring the Dahon logo. Compared to the rubber caps used in the K3+, this design undoubtedly appears more refined, reflecting the meticulousness and care characteristic of Japanese craftsmanship.

Unique Japanese Labels on the K9X

When discussing the Japan version of the K9X, we can't overlook the presence of Japanese labels. Rest assured, this bike does not feature any Chinese labels. The Japanese labels are primarily located on the head tube and frame.

These labels not only showcase the Japanese identity of the K9X but also highlight Japan's emphasis on product safety. Such thoughtful design details undoubtedly enhance the overall brand image, reassuring users about the bike's safety standards.

Configuration Comparison: K9X vs. K3+

In terms of other configurations, the K9X largely aligns with the K3+. This includes features such as sponge grips, 140mm disc brakes front and rear, and Dahon's 9-speed transmission system.

In terms of price, the selling price of the K9X is similar to the pricing in Japan, around 70% of the original price, but it is actually a bit more expensive than the K3+. To be honest, considering it comes with MKS quick-release pedals from Japan, this price is relatively reasonable. Additionally, the unique color design of the Japan version, which is not a standard style, adds collectible value to the K9X.

Overall, the K9X not only shares similar functionalities with the K3+ but also introduces additional appeal through its upgraded components and thoughtful design. For cycling enthusiasts, the K9X presents itself as a compelling option worth considering.
