*Default 21.7 mph; unlock to ~25 mph where legal. Range varies with rider, terrain, and assist level.
A fat-tire e-bike that promises real-world utility for everyday riders usually has to juggle a lot at once: power for hills, range for commutes, traction for sketchy surfaces, and safety gear for city traffic. The Funhang EB-S1 steps into that ring with a 26×4.0″ tire platform, a 48V 13Ah (624Wh) removable battery, a 500W brushless rear-hub motor (peaking to 1000W), and an unusually complete kit that includes fenders, a rear rack, turn signals, a horn, and a bright headlight. Out of the box, it’s 85% pre-assembled and sized for a broad rider range.
What the EB-S1 does best is remove friction from the decision to start riding. There’s throttle-only for lazy days, five PAS levels for exercise days, cruise mode for long flats, and a booster/walk mode for that last push up the driveway. On pavement it’s calm and planted; on gravel and snow it’s confident, helped by the 26×4.0 fat tires and a lockable front suspension fork. The default top speed is ~21.7 mph, and Funhang allows you to unlock it to about 25 mph for open, safe environments.
Funhang isn’t a legacy bicycle brand with decades of race heritage—it’s a value-focused e-mobility company that has leaned hard into “complete package” bikes. The EB-S1 reads like a checklist of what new riders ask for: real lights, turn signals, a rack, decent range, hill-friendly power, and a frame that can haul (up to 330 lb). Just as important, the system has been evaluated to current safety norms: the battery system carries UL 2271 and the complete e-bike system is evaluated to UL 2849 (tested by SGS), a level of diligence we now expect on any bike we recommend.
Is Funhang EB-S1 for you?
If your day-to-day riding mixes suburban streets, patchy bike paths, park cut-throughs, and the occasional winter or beach excursion, the EB-S1 was built with you in mind. The fat tires soften cracked pavement and add float in sand or snow. The 1000W peak motor has enough punch to pull through short hills, even with a full backpack or groceries on the rear rack. For newer riders who value stability over razor-sharp handling, the wide contact patch delivers confidence without demanding perfect technique.
It’s also a compelling “car-light” option if you want a straightforward commuter with cargo capacity. The rear rack is ready for a milk crate or panniers, and the included fenders keep you dry when the road isn’t. The LCD display is simple, with the vital stats—speed, battery, trip/odo, and PAS level—large and legible. Add in cruise control and turn signals, and it feels more mature than many entry-level e-bikes.
Who should skip it? Performance-oriented mountain bikers who want a mid-drive motor, full suspension, and hydraulic brakes will outgrow this bike quickly. Ultra-long-distance commuters who expect 40+ throttle-only miles should look at larger batteries. If you live in a walk-up apartment or need to carry a bike frequently, the 68.3-lb weight could be a deal-breaker. And riders under ~5′3″ or above ~6′3″ may find the single frame size limiting.
Budget positioning: the EB-S1 sits firmly in the budget tier of fat-tire e-bikes, but its spec sheet reads like a mid-range model. For first-time buyers, that’s exactly the sweet spot—low barrier to entry, surprisingly complete kit.
Beginner friendliness: high. The combination of throttle, five PAS levels, a forgiving tire footprint, and walk mode makes the learning curve gentle. Assembly is straightforward with the included tools and video.
What We Like About the Funhang EB-S1
The motor/battery pairing is well-judged for a bike in this class. The 500W brushless hub with 1000W peak output never feels frantic, and the twist throttle has enough immediacy to pull into traffic or clear an intersection. On rolling terrain, PAS 3–4 is the “Goldilocks zone”—you’re contributing, but the motor does the heavy lifting. Unlocking to ~25 mph adds a useful buffer when you need to keep pace with faster bike traffic (ride responsibly and legally).
Range claims are realistic. The 48V 13Ah pack (624Wh) is honest about what it can and can’t do. In PAS at moderate speeds you can expect the advertised 55–60 miles if you’re a lighter rider on flatter ground; heavier riders or hilly routes still see solid mid-30s to 40-ish miles. In throttle-only use, the stated 28–30 miles is achievable at conservative speeds. The battery is removable and lockable, IPX5-rated, and charged in about 6.5 hours—plug it in at the office or bring it upstairs at night.
Ride quality is a standout for the price. The 26×4.0 tires, a lockable front suspension fork, and a comfortable saddle take the sting out of broken pavement and gravel. You don’t get the muted magic of a full-suspension bike, but you do get predictable control and a reassuringly stable feel when roads get ugly. Paired with 180mm dual disc brakes and generous rubber, stopping remains confident, even in wet conditions.
Then there’s the equipment list. The EB-S1 includes bright front lighting, a functional tail light with turn signals, an electric horn, full-coverage fenders, a sturdy cargo rack, and a 7-speed drivetrain that’s geared sensibly for mixed terrain. Little touches—like cruise control and a booster/walk mode—show that someone at Funhang actually rides in the real world.
Lastly, safety and support: it’s pre-assembled to 85% with clear instructions and video. Funhang backs the bike with a 12-month warranty. The fact that the battery system is UL 2271 and the complete electrical system is evaluated to UL 2849 is a meaningful confidence boost in an ocean of uncertified look-alikes.
What We Don’t Like About the Funhang EB-S1
Weight is the obvious trade-off. At 68.3 lb before accessories, this isn’t a “lift it over the subway turnstile” kind of bike. If you regularly need to carry it up stairs or onto a rack without a ramp, plan accordingly. The fat-tire format inherently adds mass, and while that pays dividends in stability, it dulls acceleration compared with lighter 27.5″ commuter e-bikes.
Braking and suspension are competent, not premium. Mechanical disc brakes with 180mm rotors are well-tuned here, but they don’t have the one-finger power or wet-weather modulation of hydraulics. The front fork is basic and can bottom on bigger hits. If you plan to bomb rocky fire roads, this is the wrong tool.
The controls and display are simple—which is good for ease of use—but also limiting. There’s no companion app, no advanced ride metrics, and no turn-by-turn navigation. The default speed cap around 21.7 mph is conservative (you can raise it via settings), and the cadence-sensor PAS is not as natural-feeling as a torque-sensor system at low speeds. The 6.5-hour charge time is average; frequent high-milers may want a faster charger option, which isn’t bundled.
Geometry is one-size-fits-most with a relatively tall standover for shorter riders. The recommended rider range is roughly 5′3″–6′3″; if you’re at either extreme, test fit. Finally, while the 624Wh battery is plenty for mixed PAS use, heavy throttle-only riders or big-hill commutes will want a bigger pack.

Opinion on the feature set: this is the rare budget fat-tire bike that doesn’t feel like a “kit you need to finish.” The EB-S1’s stock configuration covers day-to-day commuting, nighttime visibility, wet-weather riding, and light cargo duty. The power system is matched to its mission: maintainable speeds around 20–25 mph, practical range in PAS, and enough torque to avoid the dreaded “bog down” at the base of a hill. While mechanical brakes and a basic fork mark the line between budget and premium, they’re competent choices here—and easily upgraded later if you crave more bite or plushness.
How it rides (real-world notes)
Comfort and control. The fat-tire/rigid-rear formula works. Even at lower tire pressures for snow/gravel, steering remains predictable. The tall head tube and wide bars encourage an upright posture, reducing strain on wrists and back during longer rides. Saddle comfort is above average for the class; most riders won’t need a suspension seatpost unless they frequent washboard trails.
Power delivery. The cadence-sensor PAS engages smoothly by budget-e-bike standards. PAS 1–2 are gentle enough for boardwalks and shared paths; PAS 3–4 is where commuters will live; PAS 5 is a short-burst setting for headwinds or hills. Throttle response is progressive and avoids the jerky on/off of cheap controllers.
Noise and feel. The hub motor has the usual faint whirr under load, and chain slap is minimal thanks to tidy routing. Nothing rattles, even with the included fenders and rack. The fork is quiet but, being a basic coil unit, it doesn’t offer the nuanced small-bump sensitivity of an air fork.
Handling cargo. With a crate on the rack and 15–20 lb aboard, the bike remains stable. The long wheelbase and tire footprint help here; the trade-off is slower turn-in around tight corners. For grocery runs this is a plus—predictable beats twitchy.
Wet and winter. The stock tires are true “all-terrain” patterns with genuine siping. On snowy multi-use paths, running lower pressures makes a dramatic difference in float and braking traction. The mechanical discs are decently sealed; pair them with quality pads when you replace the originals, and they’ll remain reliable through winter.
Maintenance & upgrades worth considering
- Hydraulic brake upgrade. If you ride steep hills or carry frequent cargo, a set of budget hydraulics (e.g., 2-piston mineral-oil systems) is a worthwhile upgrade.
- Puncture-resistant tubes or sealant. Fat tires are more forgiving, but flats still happen; a little sealant adds peace of mind.
- Rear rack accessories. Panniers for commuting or a top-mounted crate with bungee netting turns the EB-S1 into a practical shopping companion.
- Suspension seatpost. If your routes include cobbles, it’s the most comfort per dollar you can add.
- Spare charger. Keep one at the office to top up during the workday.
- Security. The removable battery locks to the frame, but invest in a quality U-lock and a cable for the wheels/rack when parking outside.
Safety notes & rider setup
The EB-S1’s electrical system complies with modern e-bike safety evaluation standards (UL 2271 for the battery pack and UL 2849 for the complete system, tested by SGS). That doesn’t replace common sense.
Charge on a hard, non-flammable surface; avoid using damaged cords; and don’t store the battery in extreme heat. On the bike, set tire pressure to your terrain and weight (lower for sand/snow/gravel, higher for smooth pavement).
Take ten minutes to adjust brake lever reach and saddle height; good fit transforms control and comfort.
The bottom line: who will love it?
If you’re buying your first e-bike and want one machine that does weekday commutes, weekend rail-trails, winter rides, and the odd beach cruise—with minimal tinkering—the Funhang EB-S1 is an easy recommendation.
It rides with the quiet confidence of a heavier, pricier bike, hauls real cargo, and comes with the visibility features (turn signals, horn, bright headlight) that matter in city traffic.
Riders chasing ultimate speed, ultra-long range, or technical trail performance should look elsewhere; everyone else will appreciate how much everyday ability this bike delivers for the money.

9.0/10
The Funhang EB-S1 nails the fundamentals that make e-bikes transformative: it’s comfortable, confidence-inspiring, and ready to commute or explore right out of the box. The 500W hub motor’s 1000W peak output and the 48V 13Ah battery are a balanced pair—strong enough for hills and spirited city speeds, efficient enough for a full day of mixed PAS riding. Add in the complete accessory kit, a 330-lb payload, and UL-evaluated electrical safety, and you have a budget bike that behaves like a grown-up commuter.
We’re not blind to the compromises. It’s heavy, the fork and mechanical brakes are basic, and the display is strictly utilitarian. But those are rational trade-offs that keep the price low without undercutting the ride. If your checklist reads “stable on bad roads, real lights and rack, decent speed and range, simple to live with,” the EB-S1 deserves the top spot.
Recommendation: Buy it if you want an all-terrain, all-weather, all-day-practical fat-tire e-bike without the upgrade spiral. Consider hydraulic brakes later if you ride steep terrain or carry heavy loads.
