When it comes to folding electric bikes, the market is absolutely buzzing with new models every year, each promising to be faster, stronger, and more reliable than ever before. The Cybervelo EK4 Electric Bike stands out at first glance with its striking design, impressive battery specs, and a motor that’s built for serious commuting and even weekend adventures. If you’ve ever wanted a foldable e-bike that doesn’t feel like a compromise, the EK4 looks like a compelling option.
The Cybervelo EK4 is a 1000W folding electric bike equipped with a 48V 20.8AH removable battery, boasting a 30+ MPH top speed and an 80-mile maximum range (under optimal conditions). It’s designed for adults who demand versatility: whether you’re battling the daily commute, tackling hills, or exploring off-the-beaten-path trails, this bike has the power and stamina to get you there. Even at a glance, the robust 20″ fat tires, rugged build, and full suspension setup make it clear that this isn’t your average city bike.
Launched in 2024, the EK4 is Cybervelo’s flagship folding e-bike. Over the last year, Cybervelo has refined the EK4 based on rider feedback, especially in battery management and ride comfort. While the core 1000W brushless motor and sturdy folding frame remain unchanged, the latest batch now features improved waterproofing (IPX4 rating), enhanced braking performance, and a more intuitive LCD display for real-time riding data. Cybervelo as a brand is known for making commuter-friendly electric bikes that deliver high value at an accessible price point, and the EK4 is no exception.
Is the Cybervelo EK4 for You?
The Cybervelo EK4 is designed primarily for riders who want both convenience and capability in a single package. If you’re a commuter tired of crowded public transport, or someone who needs a powerful ride to conquer hills and longer distances, the EK4’s high torque motor and extended battery range make it an excellent fit. The 20″ fat tires and full suspension offer additional comfort, especially if your routes include rough city streets, gravel, or light off-road paths.
For casual riders, beginners, and those just entering the world of electric bikes, the EK4 is actually quite user-friendly. The folding mechanism is straightforward, and the LCD interface is easy to understand, with clear battery, speed, and PAS (Pedal Assist System) level readouts. With three riding modes and five pedal assist levels, you can gradually learn how to maximize the motor’s assistance.
However, if you’re seeking the lightest or most compact folding bike, the EK4 might feel a bit overbuilt due to its powerful motor, battery size, and fat tires. For urbanites in tight apartments or those who need to carry their bike up several flights of stairs every day, the 65-pound weight could be a challenge. Additionally, if you’re strictly a leisure cyclist with minimal range or power needs, a smaller, lighter e-bike might suffice.
When it comes to budget, the EK4 falls comfortably in the mid-range for folding e-bikes. It’s not the cheapest model out there, but you’re getting a robust set of features and a premium battery for your investment. For anyone serious about daily use or weekend adventures, the value proposition is hard to beat.
What We Like About the Cybervelo EK4
There’s a lot to appreciate about the Cybervelo EK4, but let’s start with the motor. The 1000W brushless motor (with 1500W peak power) delivers an exhilarating riding experience. Acceleration is immediate, and the bike doesn’t hesitate on hills—something that sets it apart from underpowered commuter e-bikes. The torque is especially impressive, and you can feel the difference when carrying groceries or riding with a loaded backpack.
The battery life is another standout. With a 48V 20.8AH removable battery, you’re looking at up to 80 miles of range on pedal assist under ideal conditions, and even with heavy throttle use, you can expect well over 50 miles. For real-world commuters, this means you can go multiple days without charging, and the removable design makes it easy to take the battery inside for recharging.
Ride comfort is a third major win. The 20″ x 4″ fat tires soak up bumps, and the full suspension system (front fork and seatpost) genuinely reduces vibrations on uneven terrain. Whether you’re traversing potholed streets or light trails, the EK4 feels stable and forgiving.
Braking performance is excellent thanks to the front and rear disc brakes and EABS power-off system. Even at higher speeds or when descending, stopping power is consistent and reliable.
The LCD display is clear, easy to read, and provides everything you need at a glance—speed, mileage, battery level, and PAS mode. The inclusion of USB charging is a thoughtful touch for those who need to top up a phone on the go.
Finally, the folding mechanism is solid. It locks securely and doesn’t feel flimsy or awkward, making the EK4 suitable for city dwellers who need to tuck the bike under a desk or into a car trunk.
What We Don’t Like About the Cybervelo EK4
No product is perfect, and the EK4 has a few drawbacks worth mentioning. The first is weight: at over 60 pounds, it’s heavier than many folding e-bikes. While the robust build inspires confidence and stability, carrying it upstairs or onto public transit can be cumbersome for some riders.
Another consideration is the size—when folded, the EK4 is still quite bulky due to the fat tires and frame design. It fits in most car trunks, but it’s not as compact as a minimalist folding bike.
The LCD display, while functional, could use backlighting for better visibility in bright sunlight or at night. Some users may also find the PAS system’s five levels a bit aggressive, with larger jumps between modes compared to more granular systems.
The bike arrives 90% pre-assembled, but some assembly is still required—mainly attaching the pedals, seat, and checking the brakes and gears. For first-time bike owners, the process may be a little daunting without a video guide.
Finally, while the 330-pound load capacity is generous, riders at the upper end of that range may notice a decrease in acceleration and range, especially on steep inclines.

The fat tires inspire confidence on gravel and rougher surfaces, and the flexible PAS and gearing system offer a tailored ride for different fitness levels or commutes.

Overall, the features are not just impressive on paper, but translate to a robust and enjoyable riding experience in real-world conditions.
Final Breakdown
9.3 / 10
The Cybervelo EK4 Electric Bike scores an impressive 9.3 out of 10 in our review. For a mid-range folding e-bike, it delivers exceptional performance, comfort, and battery life, backed up by a sturdy, thoughtful design and plenty of user-friendly features. Whether you’re a commuter, an urban explorer, or someone who wants a reliable and fun ride for weekend adventures, the EK4 is a fantastic choice.
The only real caveats are its weight and folded size, which are understandable trade-offs for the level of equipment and power you’re getting. If portability is your absolute top priority, you might want to consider something smaller—but if you need a bike that can handle real-world commutes, rougher terrain, and even some light off-road use, the EK4 will not disappoint.
I have no hesitation recommending the Cybervelo EK4 to anyone seeking a versatile, high-performance folding e-bike that can do it all—without breaking the bank.
