Unboxing and Assembling was Easy

Unboxing and assembling the KBO K1 was a straightforward experience, highlighting the bike’s user-friendly design.

Right out of the box, the K1 presents itself in a nearly ready-to-ride state, requiring minimal assembly that can be completed without professional help. This simplicity is a testament to KBO’s commitment to accessibility, making the e-bike journey as seamless as possible from the very start.

Assembly requires just a few simple steps, beginning with unfolding the bike. The frame snaps securely into place with a reassuring click, indicating it’s ready for the next steps.

The pedals, marked for left and right, screw on intuitively—right pedal clockwise, left pedal counterclockwise, ensuring a snug fit without the need for excessive force.

In less than 20 minutes from breaking the seal on the box, the K1 stands ready for its maiden voyage. This ease of setup not only makes the K-Series accessible to e-bike novices but also reflects the thoughtful engineering behind its design.


500W Motor and 20 mph Top Speed

The heart of the KBO K-Series’ appeal lies in its 500W brushless geared hub motor, a powerhouse that delivers a harmonious blend of efficiency and agility. This motor ensures riders can reach the bike’s top speed of 20MPH with ease, making urban commutes not just feasible but enjoyable. Its performance on flat terrain is smooth and responsive, offering a ride that feels both spirited and controlled.

Hill climbing with the K1 reveals the motor’s robust capabilities. It tackles inclines confidently, maintaining a steady pace even on slopes of up to 30°.

This is particularly notable for an e-bike at this price point, where expectations for hill performance may be modest. The K-Series pleasantly surprises, proving itself as a reliable companion for varied urban landscapes.

The throttle feature enhances the K1’s versatility, providing an immediate boost of power on demand. This is especially useful for quick starts at intersections or for an extra push when climbing hills.

Unlike pedal-assist which requires a few pedal rotations to engage, the throttle responds instantly, offering full power without the need for pedaling.

Removable Battery and Range

Central to the KBO K-Series’ design is its removable 48V 10.4 Ah LG lithium battery. Sheltered within the frame, the battery benefits from added protection against rain and dust while contributing to the bike’s sleek aesthetic.

Security is another advantage; with the turn of a key, the battery detaches effortlessly, allowing for easy transport or charging indoors—a boon for riders without accessible charging points near their storage areas.

The range offered by this battery stands out, with up to 25 miles in pure electric mode and an impressive 45 miles when utilizing pedal assist. This variance caters to different riding styles and needs, whether it’s short daily commutes or longer exploratory rides over the weekend.

Moreover, the battery’s integration into the bike’s design ensures a balanced distribution of weight, enhancing the bike’s stability and handling.

Mechanical Disc Brakes

Mechanical disc brakes are known for their consistent performance, whether in dry or wet weather, giving riders confidence in their ability to stop promptly when needed.

The direct feedback and control provided by these brakes enhance the riding experience, allowing for nuanced modulation without the abruptness sometimes associated with more advanced hydraulic systems.

While they might require manual adjustments over time, their simplicity and effectiveness make them a suitable choice for the urban cyclist, balancing safety with ease of maintenance.

7-Speed Gearing

The KBO K-Series features the Shimano Tourney 7-speed gear derailleur, a component specifically chosen for its reliability and ease of use in urban cycling environments.

The Tourney series, a staple in Shimano’s lineup, is designed for entry-level bikes, offering a straightforward and durable solution for riders new to e-biking or those who prioritize simplicity and functionality.

By incorporating the Shimano Tourney, the K-Series ensures a user-friendly riding experience, making it easier for cyclists to maintain a comfortable pace and efficiency on their commutes or leisure rides.

Ride Experience

Embarking on my journey with the KBO K1, the bike’s performance immediately struck a chord.

The 500W motor propelled me forward with a zest that felt both exhilarating and controlled. Navigating through the urban landscape, its acceleration was responsive, allowing me to weave through traffic with confidence.

Climbing hills, a task often daunting for cheaper e-bikes was surprisingly manageable. The motor’s torque was evident, maintaining momentum without overwhelming me or requiring excessive effort.

Switching between the Shimano Tourney gears was seamless, each shift complementing the motor’s power to adapt to varying terrains.

The mechanical disc brakes provided reassuring stops with minimal effort, instilling confidence in urban settings where quick reactions are paramount.

My rides, extending over diverse cityscapes, showcased the KBO K-Series’ commendable balance of agility, power, and reliability. This bike not only met my expectations for daily commutes but also invigorated my weekend explorations with its spirited performance.

Design and Features

Folding Frame

The folding frame of the KBO K-Series epitomizes convenience, transforming the e-bike from a robust mode of transport to a compact, manageable package in mere seconds.

This feature is a game-changer for urban dwellers with limited storage space or commuters who mix cycling with public transportation.

The two-step folding process is intuitive: a quick release of the frame clamp and a lowering of the handlebar stem. In about 20 seconds, the bike’s form factor is significantly reduced, making it simple to carry, store in a car trunk, or tuck away in a closet or under a desk.

This ease of transformation encourages more frequent use, as the usual deterrents of size and storage become non-issues. The KBO K-Series’ foldability not only enhances its utility but also its appeal to a broad spectrum of riders, for whom convenience is as crucial as performance.

Wheels and Tires

The KBO K-Series is outfitted with 20″ x 3″ CHAOYANG tires, striking an ideal balance between durability and performance. These fat tires are a standout feature, offering enhanced traction and stability across a variety of terrains.

The wider tire surface ensures a comfortable ride, absorbing bumps and providing a smoother experience on rough city streets, gravel paths, or even mild off-road trails. This tire size also contributes to the bike’s overall agility, making it easier to maneuver in tight urban spaces while still offering the confidence needed on more adventurous routes.

The CHAOYANG brand, known for its quality and resilience, means these tires are built to last, requiring less frequent replacements.


The KBO K-Series enhances rider comfort and control through its dual front suspension fork, a feature particularly beneficial in urban environments. This suspension system plays a pivotal role in absorbing shocks from uneven road surfaces, curbs, and potholes, ensuring a smoother ride.

By mitigating the impact of rough terrain, it not only improves the overall cycling experience but also reduces rider fatigue, allowing for longer, more enjoyable rides.

Furthermore, the enhanced traction and stability offered by the front suspension contribute to safer handling and maneuverability, crucial aspects when navigating through busy city streets.

Fenders and Rack

The bike is thoughtfully equipped with aluminum alloy fenders and a detachable rear rack, marrying functionality with practical design.

The fenders offer robust protection against road spray, mud, and debris, keeping riders clean and dry in varied weather conditions.

The rear rack, with its sturdy build and generous load capacity, significantly enhances the bike’s utility. It’s perfect for everything from daily commutes with a backpack or groceries to weekend adventures with camping gear.

Differences Between KBO K1 and K2

The KBO K1 distinguishes itself with a traditional folding frame, akin to the popular Lectric bikes, designed for versatility and ease of storage.

In contrast, the K2 features a slightly lowered top tube, enhancing accessibility compared to the K1. This subtle modification aids in mounting and dismounting, offering a blend of convenience and efficiency for riders.

Both models are tailored to meet the urban commuter and leisure rider’s needs, balancing affordability with functional performance. Choosing between the KBO K1 and K2 comes down to personal preference for frame design and functionality, with each aimed at enhancing the daily commute and recreational outings.

In conclusion, the KBO K-Series stands out as a compelling entry into the world of e-biking, offering an ideal blend of performance, convenience, and versatility.

Its thoughtful design, from the robust motor and battery range to the practicality of its folding frame, wheels, and tires, caters to a wide spectrum of riders.

Despite its modest price point, the K-Series does not compromise on delivering a satisfying ride experience. For those venturing into e-biking or seeking a versatile, budget-friendly option, the KBO K-Series emerges as a standout choice, ready to transform daily commutes and weekend adventures alike.
