You’ve probably never seen an electric bike like the Euybike K6 Pro. This new model ambitiously combines foldability with full suspension and fat tires. It also boasts additional features such as a double-crown fork and a winged seat. But, has the brand overreached with this design? Continue reading this in-depth ebike review to discover whether the K6 Pro’s unique design revolutionizes the game or breaks the deal.
Upgraded
In its name, this model’s “pro” designation highlights its upgraded components and extended battery life, surpassing its predecessor. The K6 Pro exemplifies the latest versatile, do-it-all bikes, characterized by its foldability, full suspension, and fat tires—a trend gaining traction in the entry-level ebike market. While opinions vary on the necessity of packing so much functionality into a single bike, especially considering the added weight, the availability of such an option is something I value.
1000W Motor
The Euybike K6 Pro, promoted by Euybike for its extensive range, is, in my opinion, eclipsed by its remarkably potent motor rather than the battery life statistics. Featuring a rear hub motor with a staggering peak output of 1500W, 96.5Nm of torque, and a continuous rating of 1000W, this power demands attention as the ebike accelerates rapidly from the starting line, possibly even too rapidly.
Euybike claims a mere 1.6 seconds are needed to accelerate from 0 to 15 mph, and while I didn’t have my stopwatch at the time, I harbor no doubts about it.
Speed
There are 5 pedal assist levels and a throttle mode that reached a maximum of 30 mph during testing. However, the lowest pedal assist level consistently accelerated to 16 mph, and speeds only increased from there. I often prefer cruising at around 10 mph, especially on crowded paths or in stop-and-go traffic. Furthermore, the trails I tested were legally limited to 15 mph (10 mph in some sections). I had to lightly feather the throttle to use the motor at speeds lower than 10 mph.
Having such high top speeds is great on wide, open roads, but I didn’t enjoy having to focus on reining in the Ke Pro’s pace in slower areas. The lurching motor was also reasonably noisy during acceleration, noticeable to people I passed on the trail. For the speed demons out there, though, this ebike is one of the latest ones I’ve tested and a real blast when you can safely (and legally!) open up that throttle. The substantial amount of torque also aids in steep gradients, and I could climb hilly, rough terrain with ease.
Battery
The frame of the Euybike K6 Pro neatly accommodates a high-capacity 25Ah battery, as showcased in a photo by Connor Burkesmith for Mountain Weekly News.
To energize this high-speed ebike, a substantial 25Ah battery is employed. Most long-range bikes typically feature 20Ah battery packs, making the K6 Pro particularly noteworthy in this aspect. Despite its weight of B1 lbs., the ebike boasts an 80-mile range on a full charge. The charging process for the sizable battery takes between 8-10 hours, which is reasonable given its capacity.
Riders can monitor the remaining battery life, current speed, and other metrics on the black-and-white display positioned at the center of the handlebars. The wide riser-style handlebars provide ample space for attaching a phone, additional light, or other accessories. However, despite the available space, the right-hand twist throttle and trigger shifter felt uncomfortably close, necessitating awkward thumb positioning at times.
Design
The Euybike K6 Pro has its distinctive folding design as its most noticeable feature. Instead of folding in half through a simple hinge in the middle of the frame, it employs an overlapping hinge mechanism. I use the term “overlapping hinge mechanism” because the downtube extends past the central folding column around which it rotates.
I speculate that Euybike implemented this design to accommodate a larger, longer battery that can only be removed when the bike is folded in that specific manner. Unlike traditional hinges, users can rock the bike forward, utilizing its own momentum when the hinge is opened, which aids in collapsing the heavy bike. The hinge is loosened via a dial near the bottom bracket.
While the K6 Pro can fold in half, it is unlikely to save much space that way. The result is a voluminous, cube-like mass of a heavy bike that is challenging to move around. Nevertheless, this transformation could prove useful in scenarios such as fitting it into an RV or a large SUV trunk.
Back Seat
The unique curved seat, in addition to the bike’s innovative folding mechanism, caught my attention. I had never seen such a feature before. The seat’s concave shape sweeps significantly, with wide edges curving upward, creating the appearance of wings. The combination of this distinctive look and the futuristic frame design led us to dub the K6 Pro as the “batmobile of bikes.” While the saddle is very comfortable, it is a bit oversized for sporty, consistent pedaling; rather, it serves more as a throttle throne for pedal-free fun.
Curved Seat
The curved bike seat boasts a robust full suspension system that effectively conquers the trails. It features a mono rear shock and a double-crown front fork, a component typically reserved for downhill mountain bikes. The suspension package delivers an exceptionally comfortable ride, effortlessly absorbing bumps and curbs. Additionally, the 20 x 4″ fat tires enhance stability and provide added shock absorption.
The K6 Pro demonstrated outstanding performance on gravel and dirt paths, offering ample grip. However, a drawback is that the double-crown design significantly enlarges the K6 Pro’s turning radius. The stanchions collide with the frame, preventing riders from sharply turning the front wheel during tight corners or u-turns. Therefore, anticipate the need to dismount and pivot the bike for a 180° turn.
Gearing
On the componentry side, Shimano provides an 8-speed gearing system, and dependable Logan hydraulic brakes enhance the braking performance. The motor’s speed is such that I found myself spinning out while pedaling, even in the low assist levels. To address this, the bike could benefit from a larger front chainring. The foldable pedals add a nice touch, but they feature a raised ridge around the spindle that uncomfortably presses into your foot. A large headlamp with two brightness modes and flashing brake lights is integrated into the back of the saddle.
Verdict
I found myself contemplating the Euybike K6 Pro overpowering nature more than once during my testing, even though complaints about an ebike being too powerful are rare. However, this assessment reflects my preference for pedal-assisted rides on tranquil bike paths. Nevertheless, if you crave speed and seek an all-terrain electric beast, the Euybike K6 Pro E-Bike (priced at $1,399) is a fun choice that allows you to channel your inner Bruce Wayne. At just $1,399, you get a substantial amount of bike for a remarkably affordable price.
