If you’ve been shopping for an electric bike lately, you’ve probably noticed a familiar promise attached to many 48V/750W e-bikes:
“Up to 60–80 miles per charge.”

It sounds impressive—but does it actually happen in everyday riding?

The short answer: sometimes, but not usually.
The longer answer is more interesting, and it’s where most buyers gain (or lose) confidence in their purchase.

This guide breaks down claimed vs real-world range, explains why the gap exists, and uses a simple comparison chart so you can quickly understand what’s realistic in 2025.

What Manufacturers Mean by “Claimed Range”

When brands publish range numbers, they’re typically measured under controlled, ideal conditions, not daily riding.

Most tests assume:

• • Flat terrain
  • Lightweight rider (~150 lb / 68 kg)
  • Lowest pedal-assist level
  • Steady speed (15–20 mph)
  • No wind, no frequent stops

Under these conditions, a 48V/750W e-bike can approach its maximum advertised range. But real-world riding rarely looks like this.

Important mindset shift:

Claimed range is a best-case ceiling, not an average result.

Why 48V Alone Doesn’t Guarantee Long Range

Many buyers focus on voltage first, but battery capacity matters more.

A 48V system simply describes electrical pressure—not how much energy is stored.

Typical 48V battery sizes:

• • 48V 10Ah ≈ 480Wh
  • 48V 15Ah ≈ 720Wh
  • 48V 20Ah ≈ 960Wh

Two e-bikes can both be labeled “48V/750W” yet differ in real-world range by 30–40 miles depending on battery size and efficiency.

The 750W Motor: Power vs Efficiency

A 750W motor offers strong performance, especially compared to 500W systems.

Benefits:

• • Excellent hill climbing
  • Faster acceleration
  • Better for heavier riders or cargo
  • Ideal for fat-tire and all-terrain e-bikes

Trade-off:

• • Higher power draw at speed
  • Throttle use drains batteries quickly
  • Riding at 25–28 mph consumes far more energy

A 750W motor doesn’t force poor range—but it makes it easier to ride inefficiently.

Claimed vs Real-World Range (Quick Comparison Chart)

Below is a realistic breakdown based on rider reports, shop testing, and industry averages.

Riding Style / Conditions	Typical Range
Manufacturer claim (ideal test)	60–80 miles
Low pedal assist, flat terrain	50–65 miles
Mixed pedal assist, city riding	35–50 miles
High assist or hilly terrain	25–40 miles
Throttle-heavy riding	20–30 miles

Key insight:
Most riders see 70–85% of the advertised range, depending on how and where they ride.

The Biggest Factors That Reduce Range

Understanding these variables matters more than the motor rating itself.

1. Rider weight & cargo

Heavier loads increase motor effort and energy consumption.

2. Terrain & elevation

Long climbs are the single biggest range killer—often reducing range by 30–50%.

3. Speed

Aerodynamic drag increases rapidly above 20 mph. Riding at 28 mph instead of 20 mph can nearly halve your range.

4. Tires & pressure

Fat tires and low pressure dramatically increase rolling resistance.

5. Weather

Cold temperatures can reduce lithium battery efficiency by 10–20%.

Why Claimed Range Still Has Value

Even if it’s optimistic, published range numbers aren’t useless.

They help you:

• • Compare bikes within the same category
  • Spot undersized batteries
  • Understand relative efficiency

Some manufacturers and motor-system providers—such as Bosch—now publish mode-based range estimates, which is a growing industry trend toward transparency.

How to Get Closer to the Advertised Range

Smart riding can add 10–25 extra miles without changing your bike.

Practical tips:

• • Use lower pedal-assist levels whenever possible
  • Ride at a steady cadence instead of sprinting
  • Limit throttle to starts and steep hills
  • Keep tires properly inflated
  • Shift gears—don’t rely on motor torque alone
  • Remove unnecessary weight and accessories

Many riders are surprised how much range improves simply by backing off top speed.

Are Range Claims Misleading?

Not exactly—but they’re often misunderstood.

Manufacturers advertise the maximum possible result. Buyers often assume it’s the minimum they should expect.

A more accurate way to read the label:

“Up to 70 miles” really means “70 miles under ideal conditions.”

Once expectations are set correctly, 48V/750W e-bikes actually perform very well for their class.

Who Should Choose a 48V/750W E-Bike?

This configuration is best for riders who prioritize:

• • Power and acceleration
  • Hilly or mixed terrain
  • Heavier body weight or cargo hauling
  • Daily commuting with regular charging

If ultra-long range is your top priority, a lighter commuter e-bike with a smaller motor may be a better match.

FAQ: 48V/750W E-Bike Range

Do all 48V/750W e-bikes have the same range?

No. Battery capacity (Wh), efficiency, and riding style matter far more than the motor rating alone.

Is throttle use bad for range?

Yes. Heavy throttle use can reduce total range by 30–50%.

Does riding slower really help?

Absolutely. Dropping from 28 mph to around 20 mph can nearly double your range in some conditions.

Can settings affect range?

Yes. Display and controller settings—such as power limits and assist scaling—can significantly improve efficiency.

Should I trust advertised range when shopping?

Use it as a comparison tool, not a promise. Always check battery size and real-world reviews.

Final Thoughts for Smart Buyers

So, do 48V/750W e-bikes really hit their claimed range?

Sometimes—but only under ideal conditions.

In real-world riding, most deliver solid, predictable performance with enough range for commuting, recreation, and adventure—as long as you understand what the numbers really mean.

Power sells bikes.
Understanding range helps you love the one you buy.
