If you’ve been hunting for a step-thru fat-tire e-bike that blends real-world range, hill-climbing grunt, and everyday comfort, the Vefreedom Cityrang 4.0 should be on your shortlist. It pairs a torquey 750W (1,500W peak) rear hub motor with a 48V 20Ah battery, then adds rider-friendly touches like a color LCD, a sturdy rear rack, and a low step-through frame. On paper, it promises up to 70 miles on pedal assist and about 30+ mph top speed—ambitious numbers for a compact 20″ x 4.0″ platform.

Over several weeks of mixed commuting, grocery runs, and weekend gravel loops, I focused on what a practical buyer really cares about: comfort, control, honest range, and whether the bike feels put-together or like a kit of random parts. The Cityrang 4.0 didn’t try to wow me with gimmicks. It just kept showing up with a quiet motor, stable manners, and a chassis that tolerates poor pavement and the occasional fire road without punishing your back.

EUY—the brand behind this model—leans into “do-everything utility.” The bike arrives about 90% assembled, carries a claimed 300-lb payload, and aims at riders who want the versatility of a fat-tire around town machine with enough punch for after-work adventures. In other words, it’s built for daily life first, fun second—and that’s a good order.

Is the Vefreedom Cityrang 4.0 for you?

If your core problem is combining commuting, errands, and weekend exploring with one bike, the Cityrang 4.0 nails the brief. The step-thru frame and upright posture are forgiving for newer riders and convenient for frequent stops. The 48V system with a 20Ah battery means fewer mid-week charges, and the 20″ x 4.0″ tires make bad roads feel less bad while adding confidence on dirt paths.

This bike is for riders who value comfort, stability, and range over razor-sharp sport handling. It suits city dwellers, campus commuters, RV travelers, and anyone who wants a compact frame that still carries real cargo on a stout rear rack. With 5 pedal-assist levels, a thumb throttle, and a simple 7-speed drivetrain, it’s beginner-friendly without being boring.

It is not for weight weenies or riders chasing ultra-aggressive trail geometry. If you want a silent, mid-drive mountain goat for technical singletrack, look elsewhere. Likewise, if your rides are all sub-5 miles and you don’t need cargo capacity, you may not fully exploit the bike’s long-range battery.

Budget-wise, the Cityrang 4.0 sits in the value to mid-tier segment: far more bike than bargain basement models, but without the premium price of exotic drivetrains or hydraulic brakes. Assembly is straightforward; the bike ships mostly built with clear instructions and a basic tool kit.

What We Like About the Cityrang 4.0

The 48V 20Ah battery is the star. Real-world range depends on rider weight, terrain, wind, and how much you lean on the throttle, but the pack’s 960Wh capacity delivers noticeable endurance. On my mixed “city + path” route, PAS 2–3 returned 45–55 miles before the display dipped into the last bar. That’s commuter-grade stamina, not marketing fluff. Range anxiety simply didn’t factor into weekday use.

Power delivery is smooth. The 750W hub (rated to 1,500W peak) spools up without the sudden surge some cheaper controllers produce. The throttle is easy to modulate, and PAS levels are well spaced: PAS 1 feels like a gentle tailwind; PAS 5 is brisk enough that you’ll catch yourself grinning at every green light. EUY quotes ~82–85 Nm of torque. On short, punchy hills, the bike holds speed better than most 20″ fat-tire models I’ve tested.

Comfort is a real differentiator. The combination of a front suspension fork, fat 4.0″ tires, and a shock-absorbing saddle/post setup takes the sting out of rough pavement, speed bumps, and gravel connectors. You can feel the tires working under you—there’s grip and squish—but the steering remains predictable. Add an upright cockpit and the step-thru frame and you get a bike that invites frequent, fuss-free riding.

Braking and visibility are solid. Mechanical dual disc brakes with 180mm rotors provide consistent stops with a light lever pull. Paired with motor cutoffs, they inspire confidence at 25–30 mph. Up front, the integrated headlight is bright enough for after-dusk commuting, and the rear light helps you be seen. The IP-rated display (advertised IP65) keeps doing its job in drizzle.

Lastly, utility. The rear rack feels genuinely stout, and the frame takes weight without getting wobbly. I carried groceries, a laptop backpack, and even a small camera bag using generic pannier hooks—with no heel strike on 20″ wheels. The 300-lb payload claim feels plausible in practice, especially on smooth surfaces.

What We Don’t Like About the Cityrang 4.0

Mechanical brakes are fine at this price, but hydraulic calipers would transform the feel at higher speeds or on long descents. If you ride hilly terrain daily, an upgrade later is worth considering.

The bike is not light. The spec sheet lists roughly 50 lb for the bicycle weight, but with the 20Ah battery and rack it feels closer to a typical fat-tire e-bike when lifting up stairs or onto a hitch rack. Plan charging and storage accordingly, and use the walk-assist when maneuvering up ramps.

The cadence sensor tuning favors a relaxed spin. Riders who prefer a sportier, high-cadence feel might wish for a more responsive PAS ramp or a torque sensor. The current setup is perfect for cruising and commuting, but you won’t mistake it for a mid-drive on technical climbs.

Finally, the “up to 30+ mph” claim is optimistic for many riders out of the box. I consistently saw around 30 mph on flat ground with PAS 5 and moderate effort; smaller riders or tailwinds may nudge above that, but I wouldn’t buy this bike solely chasing top-speed bragging rights.

Pros & Cons

How do these specs stack up?
For a compact 20″ fat-tire platform, the Cityrang 4.0’s 20Ah battery is a standout. Many competitors ship 12–15Ah packs that feel fine for short hops but run out of steam on adventurous weekends. EUY also gets the basics right: the fork, brakes, cockpit, and rack feel like they were chosen to work together, not just to check boxes. I would love to see hydraulic brakes and a torque sensor on a future revision, but at this tier the current setup is balanced and reliable.

Real-World Ride Impressions

Starting and low-speed control
From a stop, the throttle and PAS 1 deliver a gentle nudge rather than a lurch. That matters in busy bike lanes and crowded trailheads. The controller’s ramp-up is smooth, so rolling starts feel natural even for new e-bike riders. The step-thru frame is a godsend in stop-and-go traffic—easy to mount in street clothes, easy to dab a foot when the light turns yellow.

Climbing and speed
On a 6–8% grade near my office, PAS 4–5 kept me at 17–20 mph without redlining my cadence. That’s strong for a 20″ fat-tire bike. On flatter segments, the Cityrang 4.0 happily cruises 22–26 mph in PAS 3–4. If you punch it to PAS 5, the bike winds up close to 30 mph with a little rider input. Wind and rider weight matter here; your ceiling may vary.

Handling and comfort
The short wheelbase and wide tires produce a friendly, planted ride. You won’t carve like a road bike, but the steering is predictable and the contact patch builds confidence on gravel and in wet conditions. The fork takes the bite out of potholes, and lowering tire pressure into the mid-teens for dirt adds genuine suppleness. I never felt beat up after longer rides.

Braking and noise
Mechanical discs are quiet in the dry and require minor cable adjustments over time. Brake feel is linear, and the 180mm rotors offer good leverage. The motor hums rather than whines; chain noise is minimal. There’s the occasional saddle/post squeak on larger hits—tighten hardware and consider a touch of grease at service intervals.

Night and wet weather
The LED headlight is bright enough for suburban streets at 15–20 mph. If you ride unlit rural roads, add a bar-mounted supplemental light. The IP-rated display shrugged off mist and light rain. Tires maintain grip in the wet better than I expected for an all-rounder tread; still, be gentle with the front brake on paint lines.

Cargo and utility
The rack handles grocery runs confidently. I used a pair of 20-liter panniers and a bungee net for odd-shaped items; the frame didn’t wobble or shimmy at speed. If you plan to routinely approach payload limits, keep tires pumped to the higher side and consider upgrading to metal pedals for more stable foot support when starting under load.

Range Testing Notes

To give you realistic expectations, here are three representative rides:

• Urban commute loop (18.7 miles total) – rolling terrain, frequent stops, PAS 2–3, no throttle except for starts: battery down ~35%.
• Mixed path + gravel (28.2 miles total) – light headwinds, PAS 3 most of the time, occasional PAS 4 to climb: battery down ~55%.
• Errand day (22.4 miles total) – heavy cargo on rack, lots of throttle use between short stops: battery down ~60%.

Your numbers will vary, but these rides support EUY’s claim that the 20Ah pack transforms the ownership experience. You ride more and plan less.

Maintenance & Upgrades

The Cityrang 4.0 uses standard components, which makes home upkeep easy. Mechanical brakes and 7-speed drivetrains are straightforward to adjust with basic tools. I’d budget for:

• Spare brake pads (resin pads wear faster if you ride steep terrain)
• A quality floor pump with a gauge—fat tires benefit from pressure tweaks between street (higher PSI) and dirt (lower PSI)
• Optional upgrades: full-coverage fenders, folding lock with frame mount, and eventually hydraulic brake calipers if you descend long hills or regularly ride at higher speeds.

The 48V battery is removable for off-bike charging. Keep it between 20–80% for day-to-day use and avoid prolonged storage at 100% if you want to maximize longevity.

Safety & Fit

The published fit window targets riders roughly 5’3″ to 6’3″ with a 34″ minimum inseam. The step-thru frame lowers the standover so hopping on in winter layers or with a loaded rack is painless.

Always perform a quick pre-ride: check tire pressure, lever feel, axle tightness, and that lights function. The bike includes motor cutoffs on the brake levers, which I consider essential on any e-bike approaching 30 mph.

Who Should Choose Something Else?

• Performance trail riders wanting technical singletrack capability and precise torque-sensor response will be happier with a mid-drive hardtail.
• Minimalists who ride short, flat trips might prefer a lighter city e-bike with narrower tires and a smaller battery.
• Steep-hill commuters who weigh the practical benefits of hydraulic brakes every day may wish to either budget for a brake upgrade or seek a model that ships hydraulic out of the box.

None of those are knocks on the Cityrang 4.0; they’re reminders to buy for your use case.

Buyer Tips

• Dial your tire pressure to your route: ~18–22 PSI for mixed surfaces, ~25–30 PSI for smooth pavement (rider weight matters—experiment).
• Set PAS levels thoughtfully: 1–2 for path etiquette, 3 for city flow, 4–5 for open roads or hills.
• Secure the battery before rides and bring the key on longer trips.
• Add mirrors and a bell—small upgrades that increase safety in traffic.
• Use a smart charging routine to extend battery life and keep a log of charge cycles if you ride daily.

The Bottom Line

The Velectrec Cityrang 4.0 nails the brief for a compact, cargo-capable, confidence-inspiring e-bike. Its big battery and eager motor make every ride feel easy, the step-thru frame welcomes a wide range of riders, and the fat tires deliver comfort on the worst city streets. You give up hydraulic brakes and premium suspension at this tier, but the core platform is so solid that a couple of smart upgrades will carry you for years.

If your days involve stop-and-go traffic, potholes, steep shortcuts, and a weekly haul of groceries, this bike turns all of that into a small adventure rather than a chore. It’s not just about getting there faster; it’s about arriving fresher, with enough battery left to take the long way home.

Final Breakdown

9.0 / 10

The Cityrang 4.0 earns its score by combining a class-leading battery, a friendly step-thru design, and true everyday utility at a value-minded price point. It’s the kind of e-bike that lowers barriers: easy to ride, easy to live with, and easy to recommend.

The few compromises (mechanical brakes, basic fork) are understandable and upgradeable. For commuters and errand-runners who want comfort and capability with a side of fun, this is an excellent pick.
