Commuter-friendly cargo capability, fat-tire confidence, and a big 48V 20Ah battery—on paper, the EUY CityRang 4.0 looks like the do-it-all step-thru so many riders want. I spent several weeks riding it as my daily runabout: grocery trips with a rear basket, weekend beach paths, and a few hilly shortcuts I normally avoid. The short version? It’s a practical, high-value ebike that pairs real utility with above-average range and punchy acceleration—so long as you accept its budget-class compromises.

At its core is a 750W (1,500W peak) rear hub motor, a removable 960Wh battery (48V 20Ah), 20×4.0 inch fat tires, and a stout integrated rear rack. EUY advertises up to 70 miles per charge with pedal assist and 30+ mph top speed (some materials say 35 mph). In my rides with PAS levels 2–3 and a full rear basket, the CityRang consistently delivered long days between charges and enough grunt to flatten neighborhood hills.

EUY is a value-driven brand better known for utility-first models than for cutting-edge components. That’s the right lens for the CityRang 4.0. It’s built to carry, cruise, and simplify daily life. If you’re looking for a featherweight carbon frame or premium hydraulic brakes, this isn’t it. If you want a sturdy, fast, step-thru with range, it’s compelling.

Is the EUY CityRang 4.0 for you?

The CityRang solves a simple problem: how to replace short car trips with something easy, stable, and capable of carrying stuff. The step-thru frame makes mounting effortless with groceries or a child seat; the wide tires stabilize uneven pavement and sand-dusted bike paths; the big battery cuts range anxiety.

It’s best for riders who want utility and comfort over sport—think commuting, campus life, farmer’s market runs, beach days, and weekend exploring with a cooler or picnic bag. New riders will appreciate the upright posture and predictable handling. It fits a broad range of heights (EUY suggests roughly 5'3"–6'3"), and the 34" minimum inseam graphic felt accurate in practice: shorter riders can mount, but you’ll likely keep the seat slightly lower.

It’s not for riders chasing ultralight feel, mid-drive finesse, or mountain-bike precision. The CityRang uses an affordable cadence sensor and mechanical disc brakes. That keeps costs friendly, but if you demand hydraulic feel or a torque sensor’s natural pedal response, you’ll want to spend more elsewhere.

Budget-wise it sits in the value/budget tier for a 20Ah cargo-leaning fat-tire. Considering the included rack, full fenders, lighting, and color display, the overall package presents strong bang-for-buck. And yes, it’s beginner-friendly: assembly is straightforward, the cockpit is simple, and PAS 1–2 are mellow enough for first rides.

What we like about the CityRang 4.0

The 48V 20Ah battery is the star. With nearly a kilowatt-hour of capacity, I could ride all week doing short errands without hunting for the charger. PAS 2 got me into the mid-teens mph on flats while conserving battery; a bump to PAS 3/4 produced brisk acceleration for short hills or traffic merges. The 750W hub doesn’t feel exotic, but it’s reliably punchy. Unlocking the top end gives “keep up with city traffic” speed on clear stretches—use responsibly and within local e-bike laws.

The step-thru frame and integrated rear rack deliver genuine utility. The rack is stout, has side rails to protect the rear wheel, and plays nicely with EUY’s baskets or seat kits. I frequently tossed a backpack and a small grocery run onto it, strapped down with a bungee net. The bike’s geometry encourages an upright posture that keeps your head up and arms relaxed.

Ride comfort is better than I expected at this price. The fat tires do the heavy lifting, but the front suspension and padded saddle help smooth patched asphalt and curb cuts. On hardpack and gravel, the 4-inch rubber plus low pressures keep traction predictable. Add the dual lights—a bright headlight and a distinct rear light—and you’re visible for evening rides.

Finally, the 5-inch color LCD is clean and bright enough for sunny days, and the control pad is intuitive. I like that EUY gives five PAS levels, a walk mode, cruise, and full-time throttle. That mix lets you tailor effort, from sweat-free cruises to light fitness rides.

What we don’t like about the CityRang 4.0

The CityRang’s biggest omission at this tier is hydraulic disc brakes. The included mechanical discs with 180mm rotors are functional and easy to service, but you’ll need a firmer squeeze when descending with cargo. They can be upgraded later, but it’s an expense to note.

The cadence sensor prioritizes simplicity over nuance. PAS engagement is predictable but not as “organic” as a torque-sensor system, especially at very low speeds. If you’re used to premium bikes that mirror your leg pressure, the CityRang feels more on/off.

Suspension is entry-level. It takes the edge off, yet it’s not meant for aggressive off-road use. Keep expectations realistic and the ride is fine; treat it like a city/cargo bike first, fat-tire second.

Finally, while EUY’s materials mention up to 30+–35 mph, most regions cap Class-2/3 ebikes at 20–28 mph. Out of the box you may be speed-limited; unlocking higher speeds (if available in your market) should be done responsibly. Also, while the graphic lists the bike at 50 lb, it feels heavier when lifting onto a vehicle rack—common for 20Ah fat-tire models. Plan ground-floor storage if stairs are involved.

Feature impressions: Taken together, these parts make a confident, go-anywhere utility bike. The battery capacity leads the class at this price, the rack is more robust than many budget competitors, and the control scheme is simple enough for brand-new riders. Braking and suspension telegraph the CityRang’s price point, but they’re adequate and easy to maintain. If you prioritize refinement, plan a hydraulic brake upgrade and possibly a seatpost swap later.

Real-world performance

Acceleration & speed. From a stop, the motor spins up quickly—especially with throttle. PAS 3 is the sweet spot for urban flow without feeling twitchy. On a flat path, I cruised around 18–22 mph in PAS 3–4. Unlocked, the bike will push well past 28 mph in the right conditions; headwinds and heavier loads trim that number.

Climbing. Short, punchy hills are a non-issue. On extended grades I kept momentum by downshifting into the mid cogs and holding PAS 4. The hub motor’s steady pull matches the CityRang’s “carry and cruise” mission. For extremely steep climbs or very heavy payloads, plan to assist with your legs.

Range. With me (about 180 lb) and a loaded rear basket, I averaged 45–55 miles on mixed urban routes in PAS 2–3 before dropping to one bar. A mellow, mostly flat ride in PAS 2 yielded 60+ miles. Throttle-only drains the battery faster, but still beats smaller-pack competitors.

Ride & handling. The fat tires define the feel: they float over rough patches, keep you upright on gravel shoulders, and add confidence when curbs, potholes, or trolley tracks show up suddenly. On boardwalk-smooth pavement, drop pressure a bit and the ride becomes almost plush. The steering is stable rather than quick—perfect for riders carrying cargo or passengers.

Braking. The 180mm mechanical discs do the job, and rotors stayed quiet after an initial cable stretch-and-retighten. If you live in big-hill country, consider upgrading to hydraulics later for lighter lever feel and better heat management with cargo.

Noise & refinement. The motor produces a modest electric whir under load. Chain noise is minimal once the derailleur is dialed in. Fenders are solid and didn’t rattle after I snugged all mounting bolts post-assembly.

Weather. The bike handled mist and light rain without drama. EUY’s art lists IP65 at the handlebars and IPX4 for the battery compartment; I still avoid heavy downpours and always towel the bike dry after wet rides, best practice with any ebike.

Go Far. Carry More.

48V 20Ah battery, 300-lb payload, rock-solid 20×4.0 tires.

Comfort and fit

The upright cockpit reduces wrist pressure and encourages heads-up traffic awareness. The saddle is on the plush side; I kept it slightly nose-down to avoid pressure on longer rides. Shorter riders benefit from the step-thru, though the 34" inseam guidance means extremely petite riders may still find the standover tall with the seat at proper pedaling height.

If you ride bumpy routes often, consider two easy upgrades: a suspension seatpost and ergonomic grips. Together they transform comfort for not much money and complement the fork and fat tires.

Utility: carrying people and things

This is where the CityRang shines. The integrated rear rack supports cargo boxes, baskets, and child or passenger pads. For passenger duty, add footpegs and check your local regulations. For cargo, a simple milk crate + bungee net or a purpose-built basket lets you carry backpacks, pet carriers, or a week’s groceries. I liked that the side rails shield the rear wheel from bags and heels—nice touch at this price.

The bike’s 300 lb payload rating covers most rider + cargo scenarios. Keep handling smooth by loading heavier items low and centered, and consider a handlebar basket for light, frequently accessed items (lock, phone, sunglasses).

Safety, lighting, and visibility

The headlight is bright enough for dusk riding and helps approaching drivers see you sooner. I recommend adding a seatpost-mounted secondary blinker for 360° visibility if you ride after dark often.

The dual disc brakes provide predictable stops, and the fat tires enhance skid resistance on sand-dusted pavement.

As with any cadence-sensor bike, remember the motor can engage a moment after you start pedaling; use the dedicated walk mode for tight, crowded spaces.

Assembly and maintenance

The CityRang arrives 85–90% pre-assembled. Install the front wheel, handlebar, pedals, and accessories; then tweak brakes and shifting. EUY includes a basic tool kit that gets the job done, but a torque wrench is worth having. After your first 50–100 miles, retighten rack and fender bolts, re-true the cable tension, and check spoke tension—standard practice for new ebikes.

Maintenance is consumer-friendly: hub motors are sealed, mechanical brakes use inexpensive pads and standard cables, and the 7-speed drivetrain accepts common parts. Keep the chain clean and lubricated, and top off tire pressures weekly for best range and ride feel.

Common questions

How fast is it really?

Expect low-to-mid-20s mph in Class-3 style use; unlocked speeds above 28 mph are possible but depend on rider weight, wind, and grade. Always follow local laws.

How far will it go?

Can it handle hills?

Can I ride in rain?

Is it good for shorter riders?

Alternatives to consider

  • Hydraulic-brake fat-tire commuters: If lever feel and downhill braking are priorities, look for similar cargo-capable models with stock hydraulics and be prepared to pay more or accept a smaller battery.
  • Torque-sensor city bikes: For riders who want a more natural pedaling feel and don’t need 4-inch tires, torque-sensor commuters feel refined but often halve battery capacity in this price band.
  • Mid-drive cargo ebikes: Better hill climbing and load management, but they cost significantly more and usually ship with smaller batteries.

The CityRang 4.0 remains attractive because it threads the needle: big battery, honest utility, approachable price.

Final Breakdown

Score: 9.1 / 10

EUY’s CityRang 4.0 nails the brief of a practical, confidence-inspiring, budget-friendly utility ebike. The 48V 20Ah battery meaningfully reduces charging hassle, the 750W (1,500W peak) motor has the shove to move riders and cargo, and the step-thru frame with integrated rack turns daily tasks into easy rides. It’s comfortable, stable, and simple to live with—exactly what many first-time and returning riders need.

You are trading away premium touches. Mechanical discs require more hand force than hydraulics, and the cadence sensor is less refined than a torque system. But nothing here is a deal-breaker, and both areas are upgradable later if you fall hard for riding and want to tweak.

If your checklist reads “long range, easy to ride, carry stuff, don’t overpay”, the CityRang 4.0 belongs at the top of your shortlist. For urban errands, beach paths, campus life, and weekend exploring with a friend or kiddo in tow, it’s a capable, enjoyable partner that invites you to leave the car at home more often.
