SASIKEIBIKE E7 vs VEFREEDOM Cityrang 4.0: Which Fat Tire Electric Bike Is Right for You?

The SASIKEIBIKE E7 folding electric bike and the VEFREEDOM Cityrang 4.0 electric bike both combine fat tires, strong motor assistance, removable batteries, and an advertised riding range of up to approximately 70 miles.

However, they are designed around noticeably different riding priorities.

The SASIKEIBIKE E7 focuses on folding convenience, a 52V battery system, and full suspension, making it attractive for riders who want versatility, compact storage, RV travel, and mixed-surface riding.

The VEFREEDOM Cityrang 4.0, on the other hand, uses a low-step frame with a practical rear rack, making it particularly convenient for commuting, grocery runs, recreational riding, and riders who prefer easier mounting and dismounting.

So which one is the better electric bike for you?

This comparison looks at the most important differences between the SASIKEIBIKE E7 vs VEFREEDOM Cityrang 4.0, including motor performance, battery capacity, comfort, portability, frame design, commuting practicality, and everyday usability.

Both bikes provide similar headline performance, but the frame, battery voltage, suspension, and utility design create two very different ownership experiences.

---

1. Motor Performance: Both Offer Up to 1500W Peak Power

Motor performance is one area where the E7 and Cityrang 4.0 are closely matched.

Both electric bikes use a 750W rated rear hub motor capable of reaching up to 1500W peak output.

That additional peak motor assistance can be useful during:

• Acceleration from a stop

• Moderate hill climbing

• Riding into headwinds

• Carrying additional approved cargo

• Riding over uneven pavement

• Maintaining momentum on longer routes

Both models are listed with a maximum speed of approximately 28 MPH.

Actual speed can vary depending on rider weight, terrain, battery charge, tire pressure, weather, riding mode, and applicable local electric-bike regulations.

For most everyday riders, there is therefore no major reason to choose one bike over the other based purely on peak motor output.

The more important differences become clear when we look at the battery, frame, suspension, and intended riding style.

---

2. Battery Comparison: 52V 20Ah vs 48V 20Ah

The battery system is one of the most noticeable differences between the two models.

SASIKEIBIKE E7

The E7 uses a 52V 20Ah removable lithium battery.

A 52V system can provide a strong platform for riders who regularly use motor assistance for acceleration, hills, longer rides, and mixed terrain.

The E7 is advertised with a maximum range of approximately 40–70 miles, depending on riding conditions and assistance level.

For a deeper explanation of the battery and real-world range, read our:

VEFREEDOM Cityrang 4.0

The Cityrang 4.0 uses a 48V 20Ah removable battery and is also advertised with an estimated maximum range of approximately 40–70 miles, depending on riding conditions.

Its battery capacity provides enough flexibility for many daily commuting, neighborhood, shopping, and weekend recreational routes.

Which Battery Is Better?

The E7 has the advantage of a 52V electrical system, while the Cityrang 4.0 uses a 48V system.

However, riders should not choose an electric bike based on battery voltage alone.

Real-world range can be affected by:

• Pedal-assist level

• Throttle usage

• Rider weight

• Cargo

• Hills

• Riding speed

• Tire pressure

• Temperature

• Wind

• Stop-and-go traffic

For riders planning longer trips, both bikes provide significantly more battery capacity than many smaller last-mile commuter e-bikes.

---

3. Folding Frame vs Step-Through Frame

This may be the most important difference between the SASIKEIBIKE E7 and VEFREEDOM Cityrang 4.0.

E7: Folding Design

The SASIKEIBIKE E7 features a folding frame.

This design can be especially useful for riders who:

• Have limited garage space

• Live in an apartment

• Travel with an RV or camper

• Want to transport an e-bike in a suitable vehicle

• Need more flexible storage

• Want an e-bike for both commuting and road trips

A folding electric bike does not necessarily mean a lightweight electric bike. Fat tires, a large battery, suspension, and a powerful motor still add substantial weight.

The main benefit is reduced storage volume rather than ultra-light portability.

If RV travel or compact storage is important to you, see our detailed guide:

Best Folding Electric Bike for RV Travel and Daily Commuting: SASIKEIBIKE E7

Cityrang 4.0: Step-Through Convenience

The VEFREEDOM Cityrang 4.0 takes a different approach.

Instead of folding, it uses a low-step frame.

A step-through electric bike reduces the height riders need to lift a leg over the frame when getting on or off the bike.

This can be useful for:

• Frequent stop-and-go commuting

• Neighborhood riding

• Grocery trips

• Riders carrying cargo

• Riders who prefer easier mounting

• Recreational cruising

For riders who rarely need to fold or transport their electric bike inside a vehicle, the Cityrang 4.0's step-through frame can be more convenient during everyday riding.

---

4. Ride Comfort: E7 Has the Suspension Advantage

Both models use 20 × 4.0-inch fat tires.

Fat tires create a larger contact area with the riding surface and can provide additional stability on conditions such as:

• City pavement

• Cracked roads

• Gravel

• Packed dirt

• Grass

• Park paths

• Uneven neighborhood streets

However, their suspension systems are different.

SASIKEIBIKE E7

The E7 features front and rear suspension.

Combined with its 20 × 4-inch fat tires, the suspension system can help reduce vibration and impact when riding across rough pavement, speed bumps, gravel, and uneven recreational routes.

Cityrang 4.0

The Cityrang 4.0 uses front suspension.

For normal commuting and recreational riding, the combination of front suspension and 4-inch fat tires still provides a comfortable riding platform.

Winner for Rougher Roads: E7

If your normal route contains more:

• Cracked pavement

• Gravel

• Rough roads

• Uneven surfaces

• Recreational trails

the E7's full-suspension design may provide an advantage.

For riders spending most of their time on pavement, bike paths, and neighborhood roads, the Cityrang 4.0 remains a practical option.

---

5. Which Is Better for Daily Commuting?

Both bikes can work as commuter electric bikes, but they solve different problems.

Choose the SASIKEIBIKE E7 if:

You need to combine commuting with storage flexibility.

The folding frame can make the E7 useful for people who need to store their bike in a smaller space after arriving at home or work.

Its 52V 20Ah battery and full suspension are also attractive for longer or rougher commuting routes.

Choose the Cityrang 4.0 if:

You value easy mounting, cargo convenience, and a traditional commuter setup.

The step-through frame makes frequent stopping easier, while the rear rack provides a convenient platform for compatible bags, baskets, or other approved cargo accessories.

This allows you to compare different frame styles, tire sizes, batteries, and riding configurations before making a decision.

6. Which Bike Is Better for Grocery Runs and Cargo?

The VEFREEDOM Cityrang 4.0 has an advantage here.

Its step-through design and rear cargo rack make it naturally suited to everyday utility riding.

A rear rack can be useful for compatible:

• Pannier bags

• Grocery bags

• Small cargo baskets

• Commuter bags

• Recreational equipment

Being able to step through the frame can also make getting on and off easier when additional weight is carried on the rear rack.

For riders who regularly use an electric bike for shopping, local errands, or carrying everyday items, the Cityrang 4.0 may be the more practical choice.

7. Which Electric Bike Is Better for RV Travel?

The SASIKEIBIKE E7 has the clear advantage for RV and camper travel because of its folding frame.

When campground or RV storage space is limited, reducing the bike's overall storage footprint can make transportation easier.

After reaching your destination, an electric bike can be useful for:

• Exploring campgrounds

• Visiting local stores

• Riding around RV parks

• Exploring beach communities

• Riding local bike paths

• Short sightseeing trips

The removable battery also allows the battery to be charged or stored separately when appropriate.

Because the E7 is still a substantial fat tire electric bike, always measure the available storage compartment or vehicle cargo area before purchasing.

---

8. Which Is Better for Shorter Riders or Easier Mounting?

The Cityrang 4.0's low-step frame gives it an advantage for riders who prioritize easy entry and exit.

Traditional or folding frames require the rider to lift a leg higher over part of the bicycle.

With a step-through design, the central frame area sits much lower.

This may be useful for riders who:

• Make many stops during a ride

• Frequently load and unload cargo

• Prefer a more relaxed commuter layout

• Do not need a folding frame

• Prioritize convenient mounting over compact storage

Bike fit remains individual, so riders should always review the latest recommended rider-height information and dimensions on the official product page before ordering.

9. E7 vs Cityrang 4.0 for Weekend Adventures

Weekend riding is where both models perform well.

The E7 and Cityrang 4.0 both feature 20 × 4-inch fat tires and strong motor support, making them more versatile than many narrow-tire city bicycles.

They can be considered for appropriate:

• Park paths

• Waterfront routes

• Neighborhood streets

• Gravel paths

• Campground roads

• Recreational routes

• Light mixed-surface riding

The E7 may be the better choice if you prioritize suspension and the ability to fold the bike for transportation.

The Cityrang 4.0 may be better if you want a comfortable step-through bike that can carry additional everyday equipment on a rear rack.

Riders should always confirm whether electric bicycles are permitted on a particular trail, park, or recreation area before riding.

---

10. Which One Offers Better Value?

Instead of focusing only on motor wattage or top speed, value should be measured by how well the bike matches your actual riding routine.

Both bikes offer:

• 1500W peak motor output

• Up to approximately 28 MPH

• Large removable battery

• 20 × 4-inch fat tires

• Shimano 7-speed gearing

• Disc brakes

• Up to approximately 40–70 miles advertised range

• Everyday and recreational riding capability

The E7 puts more emphasis on:

Folding + 52V Battery + Full Suspension

The Cityrang 4.0 puts more emphasis on:

Step-Through Access + Rear Cargo Utility + Everyday Commuting

That makes the decision less about which electric bike has the biggest specification number and more about which design better fits the way you actually ride.
