The EGGKING S8 rides squarely into the booming category of 20-inch fat-tire, moto-style e-bikes. It pairs a punchy 1000W rear hub motor with a big 48V 17.5Ah battery (≈840Wh), dual suspension, and a long bench saddle that echoes small motorcycle vibes. On paper it promises up to 31 mph unlocked, confident off-road manners, and range figures that can stretch to a claimed 70 miles with pedal assist. It’s also UL 2849 listed for electrical system safety—something I always look for now.
Over several days I used the S8 as a commuter, errand-runner, and dirt-path explorer. My test loop mixed neighborhood streets, bike lanes, gravel connectors, and a few short, steep climbs. The immediate impression? This is a torque-forward fun machine. It squats and goes, floats over rough patches better than most hardtails in its class, and invites you to choose the scenic route home. It also has a few tradeoffs—weight, mechanical brakes, and a bench seat that limits exact fit tuning—that you’ll want to weigh before buying.
Think of the S8 as a practical mini-moto for adults who like a little attitude with their utility. It’s built around an iron main frame with aluminum sub-components, 20×4.0-inch fat tires, and front/rear coil suspension. Lighting is comprehensive (big headlight, tail/brake light, and turn signals), the cockpit is simple with a centered LCD and thumb controls, and the Shimano 7-speed drivetrain is a familiar, serviceable spec. You won’t find fancy electronics or featherweight components here; you’ll find sturdy parts chosen for fun, range, and value.
Is EGGKING S8 for you?
The S8 solves a common need: a do-everything e-bike that feels stable, forgiving, and powerful on mixed terrain. If your rides blend pothole-prone city streets with dirt service roads or park shortcuts, the 4-inch tires and dual suspension make an immediate difference in comfort and control. The 1000W motor adds hill confidence and headwind insurance that 500–750W bikes can’t always match, especially for heavier riders or those carrying cargo.
It’s a strong fit for riders 5’5″ to 6’5″ who prefer an upright, scooter-like posture and don’t mind a heavier platform. If you want the sensation of a small electric motorcycle while staying in a bike lane footprint—and you appreciate a long bench that’s comfortable on bumpy surfaces—the S8 makes sense. It’s also a good choice if you’ll ride at night; the lighting package and turn signals are genuinely useful.
It’s not ideal if you crave a featherweight bicycle feel, plan to carry the bike up flights of stairs, or want the ultra-natural pedaling response of a torque-sensor commuter. The S8 uses a cadence-based assist with the “on/off” personality typical in this price class. The long bench seat also limits fine-tuning of saddle height. If precise fit or low weight is a must, a conventional step-through commuter or mid-drive trekking bike may suit you better.
Budget-wise, the S8 lives in the value-to-midrange bracket of fat-tire e-bikes. It gives you more motor and battery than many budget models, plus full lighting and suspension, but it keeps costs in check with mechanical disc brakes and a no-frills display. For beginners, it is friendly: assembly is straightforward, the control layout is simple, and the wide tires bolster confidence on day one.
What We Like About EGGKING S8
The motor-battery pairing is the headline. The 1000W hub spools up quickly and holds speed with much less strain on hills than 500/750W bikes. On my test climbs (short 8–12% grades), the S8 powered up without drama in high PAS or throttle. The 48V 17.5Ah pack delivers real endurance; with mixed riding I saw range in the mid-30s (pure throttle) to low-50s (PAS 2–3), which aligns with the brand’s realistic “30-50+ miles” expectations, and you can stretch further if you keep speeds reasonable.
Comfort is another win. Dual suspension won’t turn rock gardens into silk, but it blunts curb edges, rooty paths, and choppy asphalt better than the stiff hardtails common at this price. The 20×4.0 tires are a sweet spot: compact enough for nimble city handling, yet big enough to float on grass, gravel, and light sand.
I also appreciate the safety package. A large, bright headlight with metal-style cage, a proper tail/brake light, side reflectors, and bar-mounted turn-signal switch mean you’re more visible without DIY add-ons. The LCD is readable, showing speed, PAS level, battery bars, and trip data at a glance. The long bench is comfortable, especially if you shift fore-aft during longer rides, and the 330 lb rated payload gives bigger riders room.
Finally, the UL 2849 listing brings peace of mind regarding the electrical system. The removable, lockable battery makes charging flexible, and the claimed 5–7-hour charge window matched my experience with a standard charger.
What We Don’t Like About EGGKING S8
At roughly 95 lb, the S8 is heavy. That’s expected for a dual-suspension fat-tire e-moto, but it’s worth calling out. Carrying it up stairs or mounting it on a basic car rack is a chore. If you live in a walk-up or plan frequent vehicle transport, factor that in.
The brakes are cable-actuated mechanical discs. They work, and the large rotors provide decent bite, but on a 30+ mph-capable, 95-lb bike, hydraulic discs would be my preference for feel and power—especially in wet conditions. Expect to spend a few minutes dialing in cable tension and pad alignment after initial break-in.
The cadence-sensor PAS has the usual characteristics: a slight delay before assist engages and a surge when it does. Experienced riders adapt quickly, but riders seeking “ride-like-a-bike” smoothness should set expectations accordingly. I also would have loved an included rear rack. Mudguards are in the box, which is great, but many owners will add a rack for errands.
Finally, the bench saddle’s height is fixed relative to the frame. It’s comfortable, but you can’t fine-tune saddle height for optimal pedaling efficiency the way you can on a post-and-saddle commuter. If you pedal a lot above 20 mph, you’ll feel the difference.

From a rider’s perspective, these features knit together well. The S8’s standout is how the motor, battery, and fat tires combine to make distance and terrain feel smaller. You don’t agonize over a windy day or a detour onto gravel; you just go. The mechanical brakes are serviceable and familiar, and they keep maintenance simple if you’re comfortable adjusting calipers and cables. The display is basic but functional, and the lighting/turn signals remove a common new-owner expense. The main weakness is weight, followed by the PAS feel that’s typical of cadence-sensor systems. Neither is a deal-breaker; both are realities of this style and price band.
Real-World Ride Impressions
Power & Speed
On flat ground, PAS 3–4 quickly puts you into the low-to-mid 20s mph, and PAS 5/throttle unlocks the “mini-moto” personality. The S8 holds speed with a steady hum rather than a straining whine, which builds confidence. I reserved 31 mph for empty roads and off-street connectors—be mindful of local e-bike classes and speed rules.
Climbing is where the 1000W rating pays rent. On my steepest short pitch (about 12%), many 750W bikes slow to single-digit mph unless you’re in a low gear, but the S8 stayed above 14–16 mph with PAS 5 and some pedaling, then motored over the crest without a cooldown pause. On long, gradual climbs, I could hold 20 mph in PAS 4 with a comfortable spin.
Range & Battery
With throttle-heavy riding at 20–25 mph, I consistently landed in the mid-30-mile zone before the display dropped to the last bar. Riding more like a commuter—PAS 2–3, rolling at 16–19 mph, and easing off the line gently—the S8 stretched into the low-50s and could touch higher with discipline. That tracks with the manufacturer’s split claims: ~31 miles in pure electric and up to ~70 with assist at lower speeds. For context, 840Wh is a big battery at this price; energy density is a strength here.
Charging from two bars to full took about 5.5 hours with the included charger. The frame-mounted lock is positive, and removing the pack for indoor charging is straightforward.
Handling & Comfort
The S8 places your hands slightly higher than your hips, with a neutral reach and an easy view over traffic. Low-speed balance is excellent thanks to the wide tires, and high-speed straight-line stability is very good. The bench seat shines on rough pavement; you can slide back for bumps or perch forward for turns. Suspension tuning leans plush, which is exactly what most buyers want.
Cornering on pavement requires the usual fat-tire inputs: look through the turn, lean the bike more than your body, and trust the contact patch. On gravel the S8 is forgiving and predictable; the tires bite well at moderate pressures.
Braking
Out of the box the levers felt long and a touch spongy—normal for new mechanical discs. After cable stretch settled and I adjusted pad position, braking power improved notably. The large rotors help, but physics is physics: a 95-lb bike at 25–31 mph asks a lot of any cable setup. I recommend frequent checks and considering upgraded pads or a hydraulic conversion if you’ll bomb long downhills regularly.
Controls & Display
The LCD is bright enough for midday viewing and intuitive. Speed up top, battery bars, PAS level, trip, and odometer are laid out cleanly. The left-hand control cluster puts turn signals, horn/bell, and PAS buttons under your thumb. Cruise mode engages smoothly if you hold a constant speed—handy on longer straight sections.
Safety & Night Riding
The headlight is a highlight (pun intended). It throws a wide, useful beam with a distinct cutoff so you’re visible without blinding others. The integrated tail light brightens under braking, and the turn signals are visible from the rear and sides. On an e-moto silhouette that may share space with cars more often than a skinny commuter does, that’s a big plus.
Assembly, Support & Maintenance
Assembly is straightforward: attach the handlebar, mount the front wheel and fender, bolt on the pedals and headlight, and check calipers. EGGKING’s HD video is clear, and most riders can complete setup in well under an hour. The included tools work, though I prefer my own wrenches and a torque tool for final checks.
Routine maintenance is easy if you’re handy: keep the chain cleaned and lubed, check spoke tension after the first few rides, set tire pressure for your terrain (I liked 18–22 psi on mixed surfaces), and inspect brake pads/cables weekly early on. The fat tires are tough, but I still carry a patch kit and pump; flats on 20×4 rubber are rarer than on road slicks but not impossible.
Who Should Skip It?
Skip the S8 if you need to carry your bike upstairs regularly, if you want the lightest possible platform, or if you’re hunting for a slim step-through with a Dutch-style seatpost and rack-first utility. Riders who pedal hard at 20+ mph for fitness may also prefer a torque-sensor mid-drive. Those priorities point you to a different segment.
Tips to Get the Best from the S8
- Dial your PAS levels. PAS 2–3 is the sweet spot for range and smoothness in urban riding.
- Brake-in and adjust. After 20–30 miles, re-center the calipers and snug cable tension; braking feel will improve.
- Set tire pressure by terrain. 22–24 psi for pavement, 16–20 psi for gravel and grass, lower with care for sand/snow.
- Mind local laws. 31 mph unlocked is above common Class-3 limits; ride off-road or keep it limited where required.
- Security. The battery locks, but the bike’s value means a sturdy U-lock (and ideally a second lock) is wise.
- Accessorize smartly. Add a rear rack and small panniers to turn the S8 into a solid grocery-getter without compromising the fun factor.
Comparison Notes
If you’re cross-shopping, many 20-inch fat-tire models sit at 500–750W with 48V 12–15Ah batteries. The S8’s 1000W motor and 17.5Ah pack are clear step-ups in grunt and endurance. Some rivals include hydraulic brakes or torque sensors but at a higher cost or with smaller batteries. Decide which matters most to you: power/range and dual-suspension comfort (S8’s strengths) or braking feel/fit precision (areas where other styles can win).
Final Breakdown
9.0 / 10
The EGGKING S8 nails its brief: a powerful, comfortable, mini-moto-style e-bike that’s as happy on patched-up city streets as it is on gravel connectors and park trails. The 1000W motor and 840Wh battery combination leads its price class for sheer punch-per-dollar, and the dual suspension plus 4-inch tires make the bike genuinely enjoyable for long rides on imperfect surfaces. The full lighting with turn signals and the UL 2849 listing are real-world wins, too.
It’s not perfect. Weight is high, mechanical brakes require attention, and the cadence-sensor PAS doesn’t mimic an acoustic bike’s feel. But those are reasonable compromises given the motor, battery, and comfort package you get. If you’re drawn to the mini-moto aesthetic and want a confident, capable e-bike that can tackle hills and bad pavement with a grin, the S8 is an easy recommendation.
Recommendation: Buy it if you value power, range, and comfort in a compact fat-tire format and don’t mind a heavier, moto-like personality. Add a rear rack and a sturdy lock, keep the brakes dialed, and you’ll have a versatile daily fun machine that punches well above its bracket.
