Established in 2014, Euybike’s might not be a household name, but after more than 10 years crafting electric bikes, this small California-based company has steadily built a reputation that’s hard to ignore—and caught our attention in the process.
Euybike stands for “Excellent, Ultrafast and Young,” and they focus on practical, everyday e-bikes with a distinctive moped-style design. Their latest offering, the K6F (commonly called the “Euybike K6 Pro”), is a folding moped-style e-bike that delivers Class 3 speeds with a look that’s entirely its own.
The K6F packs serious power with a 1000W motor that peaks at 1500W, delivering 96 Nm of torque. Beyond raw performance, it promises an impressive 80-mile range, supports a hefty 400lb payload, features a bold motorcycle-style headlight, and comes with several free accessories—all for a current sale price of $1,299 (down from an MSRP of $1,999).
But how does all this translate to real-world performance? Stick around to see how my testing went, discover the actual range on a single charge, learn how the motor feels and performs, plus get a complete rundown of the pros and cons in this Euybike K6 Pro review.
My Experience Riding The Euybike K6F E-Bike
The Euybike K6F has a look unlike anything I’ve encountered before—and that’s not surprising, since I occasionally get bikes that attempt to completely rewrite what an “e-bike” should or could be.
Beyond the frame’s distinct appearance with its low-slung, moped-inspired geometry, fully integrated battery, and dual-beam pivot point where it folds, the K6F projects a beefy, compact, and aggressive stance that suggests it can handle far more punishment than your average bike.
Available in three colors (yellow camo, green camo, and the dark grey I tested), the K6F delivers a full-on off-road moped meets futuristic bike tech aesthetic.
While the brand advertises that the single frame size accommodates riders from 5’7″ to 6’5″, I found that at 5’11” I was approaching the upper limit of what felt comfortable. This wasn’t about needing more seatpost length—I had plenty—but rather the relationship between seat position, pedals, and handlebars. Had I been 3-4 inches taller, my quad length would have required the seat to be positioned further back. The fit worked fine for me, but anyone approaching that 6’5″ maximum should definitely take a test ride before committing.
The seat, while visually departing from convention, proved to be one of the more comfortable saddles I’ve experienced. The curved, upward-angled sides keep you planted in the center rather than sliding around like some saddles encourage.
Saddle and fit considerations aside, I hit my local streets for the K6F’s maiden voyage. The first thing that struck me was the punch of the cadence sensor paired with the 1000W motor. The cadence sensor requires about a full pedal rotation before engaging (like a full 360 degrees) ,but, once it kicks in, it delivers sharp, immediate power—exactly what you’d want from a moped-style e-bike.
Here’s the thing though—that full 360-degree rotation caught me off guard the first few rides. I had a couple of double-takes thinking the motor wasn’t going to start, and then it kicks off pretty aggressively. Keep that in mind because it might surprise you if you’re not ready for the sudden surge of power.
The motor has a slight audible whine that’s pretty typical of higher-power e-bike motors pumping 48V, 25Ah, and peaking at 1500W with 96Nm of torque. That slight motor noise is more than compensated by the punchy, fun power on tap—whether from the throttle or cadence sensor when pedaling. The PAS levels range from 1 to 5, with speed limits tied to each setting: PAS 1 caps at around 8 mph, PAS 2 at 12 mph, PAS 3 at 16 mph, PAS 4 at 18 mph, and PAS 5 at 20 mph in Class 2 mode. Switch to Class 3, and the bike maintains that same punchy power delivery but spreads the PAS levels across a wider spectrum, reaching the 28 mph limit.
The front fork feels good and appears to offer around 80mm of travel, though Euybike doesn’t list the specs. It’s a coil fork with preload and compression adjustments plus a full lockout option—nice touches at this price point. The rear shock also lacks listed specifications, but it’s visually quite small. While I could see it actuating during rides, I’m not sure how much I could actually feel it working over that massively comfortable saddle that does the heavy lifting for rear-end comfort. It’s like a couch seat—might look big, but it sure is cozy.
Those 20-inch wheels with all-terrain knobby treads roll nicely and aren’t too loud on pavement while still providing the grip needed for off-road adventures. The higher volume of those 4-inch-wide tires means you can air down more than normal, which teams up with the saddle and suspension for even more comfort. The smaller wheel diameter keeps the bike compact when folded but still rolls efficiently enough for serious riding.
The 8-speed Shimano setup shifts cleanly and provides adequate range for most situations—though with 1000W on tap, you’ll rarely need to worry about running out of gears. The Logan hydraulic disc brakes deliver confident stopping power that matches the bike’s aggressive personality and higher speeds.
This is just a fun bike to ride, whether you’re throttling all over town taking shortcuts to class or heading out to venture beyond campgrounds on public lands to explore. While it’s not a pedal-focused bike (cadence sensor, moped geometry), it’s an engaging way to get around if you’re not looking for the classic “pedaling” bike experience. The K6F feels more like piloting a small electric vehicle than riding a traditional bicycle—and for the right rider, that’s exactly the appeal.
Range
Estimated Range (from Euybike): 55 to 88 miles
Real World Range Test Results: 41 miles on MAX Speed
Euybike estimates between 50 and 80 miles of range—50 on throttle only and 80 on PAS 1. Rather than test under ideal pedal-assist conditions, I opted for the real-world torture test: how most riders who buy a moped-style e-bike will actually ride it—full blast on PAS 5.
With a cadence sensor system, PAS 5 essentially means all power, all the time. This represents the worst-case scenario for battery consumption, asking everything the motor can give from a full charge until it taps out.
My Range Test Conditions:
- Rider weight: 175 lbs
- Terrain: Mostly flat, closed city path
- Traffic: Minimal stops (fairly ideal conditions)
- PAS level: 5 (maximum) throughout entire test
I managed 41 miles before the battery waved the white flag. This torture test suggests that dropping to lower PAS levels would likely yield 60-70 miles of real-world range. While Euybike claims 80 miles on PAS 1, that level limits you to about 8 mph—not very plausible for most riders’ actual usage.
The realistic takeaway? Expect 50-70 miles of range with typical mixed-PAS riding, which aligns well with the bike’s intended use as both a practical commuter and weekend adventure rig.
Power (Motor & Battery)
The K6F’s 1000W nominal motor (peaking at 1500W) with 96Nm of torque delivers a moped-level punch that launches you forward with authority. The cadence sensor requires about a full pedal rotation before engaging, which feels sluggish initially, but once it kicks in, the response is immediate and strong across all five PAS levels.
Lower PAS settings provide manageable assistance for casual riding, while PAS 4-5 unleash that full aggressive acceleration that can catch you off guard. The motor maintains strong performance under load—hills, cargo, hard acceleration—thanks to that 1500W peak power. Trade-offs include increased battery consumption and noticeable motor noise, but that’s expected with this level of raw performance.
Euybike’s 48V, 25Ah, 1200Wh battery pack is genuinely impressive for this price point. Real-world range hits 40-60 miles depending on conditions, with the manufacturer’s 80-mile claim achievable under ideal circumstances. The external LED indicators on the battery let you check charge level at a glance—a simple but invaluable feature for daily use.
The massive capacity means 6-8 hour charge times but less frequent charging overall. The 48V system maintains strong motor performance even as the battery depletes, unlike some 36V setups that fade. The downside? All that capacity adds significant weight, making the K6F feel more like a small motorcycle when you’re moving it around manually.
Components
The 8-speed Shimano Altus setup with trigger shifters delivers reliable shifting that’s standard for this price range. The 52t chainring and 11-34t cassette handled nearly all my riding scenarios—when gearing gets limited, that 1000W motor fills the gaps nicely. Expect some ghost pedaling above 24 mph, which is typical for this setup. The folding plastic pedals are functional but clearly a cost-saving measure worth upgrading for longer rides.
The 20″ aluminum wheels balance portability with performance, but those beefy 20″x4″ all-terrain tires are the real stars. They transform the bike’s character completely—excellent stability, road imperfection absorption, and that aggressive moped stance. Trade-offs include rolling resistance on pavement and added weight, but the versatility and comfort make it worthwhile.
Logan-branded hydraulic disc brakes with 2-piston calipers and 180mm rotors delivered consistent, confident stopping power. While not a household name, they proved reliable throughout testing. For a folding e-bike hitting 28 mph with 400-pound capacity, proper hydraulic disc brakes aren’t just nice—they’re essential for safety.
The front fork offers roughly 80mm of travel (Euybike doesn’t specify) with coil spring, preload, and compression adjustments—a pleasant surprise at this price point. Most budget e-bikes skip adjustable suspension entirely. Combined with those fat tires, it creates a genuinely comfortable ride over rough terrain.
BMX-style handlebars and fixed MTB stem create the perfect upright position for the bike’s moped character. Basic slide-on grips are functional but upgrade-worthy. The wide comfort saddle stands out with its curved design that keeps you planted—no sliding around like cheaper seats. The 350mm seatpost provides good adjustment range, though taller riders should test overall geometry first.

Euybike K6F Model Options
The K6F comes in one frame size designed to fit riders from 5’7″ to 6’5″. At 5’11”, I found it comfortable but felt I was nearing the upper limits of what I’d consider ideal—riders over 6’2″ should definitely take a test ride to check the fit before committing.
Euybike offers three colorways: the dark grey I tested, plus green camo and yellow camo variants. All share the same aggressive, moped-inspired aesthetic regardless of color choice.
As of July 2025, Euybike includes a solid accessory package: fenders, rear rack, rear rack bag, bike multitool, and a bonus one-year warranty extension for total two-year coverage. That’s genuine value-add rather than cheap throwaway items.
The rear rack handles up to 200 lbs with multiple modular mounting points for gear attachment. However, cargo options end there—the K6F lacks bottle cage mounts or other mounting bosses, so everything you carry goes on the rear rack or in your backpack.
Euybike offers extensive paid accessories including rearview mirrors, passenger foot pegs, upgraded tail lights with turn signals, bike locks, and more. The comprehensive options list suggests they’re serious about supporting long-term ownership and customization.
Is The Euybike K6F Worth Buying?
The Euybike K6F delivers on its moped-inspired promise with genuinely impressive performance for the price. That 1000W/1500W peak motor provides moped-level acceleration, the massive 1200Wh battery offers real-world range that approaches manufacturer claims, and the fat tire setup creates a stable, confidence-inspiring ride. Add in quality components like hydraulic disc brakes, adjustable suspension, and a generous included accessory package, and you’ve got solid value at $1,299.
The unique folding frame design sets it apart visually and functionally, though it comes with trade-offs. Fit becomes questionable for riders over 6’3″—definitely test ride before buying if you’re on the taller end. The proprietary frame design also means limited access to compatible replacement parts down the road, something to consider for long-term ownership.
This bike shines for college students needing campus wheels with weekend adventure capability, weekday commuters who want something a little more fun than a traditional commuter e-bike, and weekend warriors looking for off-road fun around camp or on mild trails. The folding feature makes it apartment-friendly, while that 400-pound payload capacity handles serious cargo duties.
If you’re drawn to the aggressive moped aesthetic, want genuine performance, and can live with the sizing and parts limitations, the K6F offers a unique riding experience that stands out in a crowded e-bike market. For the right rider, it’s genuinely compelling—just make sure you’re the right fit first.
