Electric Bike Buying Guide: How to Choose the Best eBike for Your Needs

Browse through our handy Electric Bike Buying Guide for everything you need to know before buying an electric bike – from motors and batteries to legal limits and best value models.

Introduction + Types of Electric Bikes

Why Electric Bikes Are So Popular Right Now

Electric bikes (also called eBikes) have exploded in popularity because they make cycling easier, faster, and more accessible. Whether you’re commuting, exploring trails, or replacing car trips, an eBike helps you go farther with less effort.

Modern electric bikes are now:

  • Lighter than older models

  • More powerful (but still legal)

  • Equipped with longer-range batteries

  • Available in every style from city bikes to mountain bikes

If you’re wondering “What is the best electric bike to buy?” — the answer depends on your riding style, budget, terrain, and how much you want the motor to assist.

Electric Bike Buying Guide

Let’s kick off the Electric Bike Buying Guide with some basics:

What Is an Electric Bike?

An electric bike is a bicycle with an integrated motor and battery that provides pedal assistance (and sometimes a throttle). Unlike scooters or motorcycles, most eBikes require pedaling to activate the motor.

Key eBike components:

  • Motor (hub motor or mid-drive motor)

  • Battery (measured in watt-hours / Wh)

  • Controller + display

  • Pedal assist sensor (cadence or torque)

(1) Commuter Electric Bikes & Leisure Electric Bikes

Best for: city riding, daily commuting, errands, fun
Typical features:

• Upright geometry •

• Lights and mudguards •

• Rear rack compatibility & click systems •

• Choice of motor power •

Ideal if you want: driving alternative on short trips, or just for fun!

(2) Electric Mountain Bikes (eMTB)

Best for: trails, hills, off-road terrain
Typical features:

• Mid-drive motor •

• Strong brakes (hydraulic) •

• Suspension (front or full) •

• High-torque motor (60–90Nm) •

Ideal if you want: maximum climbing power and trail control.

(3) Lightweight Electric Bikes

Best for: ease of handling, portability
Typical features:

• 14kg – 20kg •

• Moderately powerful motors •

• Slightly less range •

• Less bulky feel and look •

Ideal if you want: comfort, agility and less weight underneath.

(4) Folding Electric Bikes

Best for: motorhome & caravan owners, mixed commute (train + bike)
Typical features:

• Compact frame •

• Smaller wheels (16” – 20”) •

• Moderate range •

• Easy fold mechanism •

Ideal if you want: portability and easy storage.

(5) Cargo Electric Bikes

Best for: carrying kids, groceries, deliveries
Typical features:

• Longtail or front-load design •

• Heavy-duty frames •

• Strong motors + big batteries •

• Often supports dual batteries •

Ideal if you want: to replace a car.

(6) Electric Road Bikes & Electric Gravel Bikes

Best for: fitness riding, speed, long distances
Typical features:

• Lightweight •

• Smaller motors •

• Hidden batteries •

• Drop handlebars or flats •

Ideal if you want: a “normal bike” feel with extra help on climbs.

Motors, Power, Torque, and Riding Feel

The Motor Is the Heart of an eBike

The motor determines how your eBike feels when accelerating, climbing hills, or carrying weight.

Hub Drive vs Mid-Drive Motors

There are TWO main motor types, hub and mid-drive:

(1) Mid-drive Motors (e.g. Bosch, Germany)

(2) Hub Motors (e.g. Bafang, China)

THE WINNER

In our experience, there is only ONE clear winner that delivers the best ride experience and natural power delivery:
a CRANK MOTOR such as BOSCH!

 

Torque (Nm): The Real “Hill Climbing” Spec

General guide:

  • 35–50Nm = light assistance, flat terrain

  • 50–70Nm = strong commuter power

  • 70–90Nm = excellent hill climbing

  • 90Nm+ = premium performance, cargo & eMTB

If you live in a hilly area, torque matters more than top speed.

Understanding Motor Power (Watts)

Most eBikes are marketed with motor power ratings such as 250W, 500W, 750W and 1000W+

In many regions such as the UK, 250W is the legal standard for road use. In others (like parts of North America), 750W is common. Bigger watt numbers don’t always mean better.

Torque and motor efficiency matter just as much.


 

Batteries, Range, Charging, and Real-World Expectations

Battery Basics: What You Need to Know

The battery determines how far you can ride and how often you need to charge.

The key measurement is Watt-Hours (Wh).

Battery formula:
Voltage (V) × Amp Hours (Ah) = Watt Hours (Wh)

Examples:

  • 36V × 10Ah = 360Wh

  • 48V × 14Ah = 672Wh

  • 52V × 20Ah = 1040Wh

How Much Range Do Electric Bikes Get?

Most brands advertise ranges like “up to 60 miles” or “up to 120km,” but real-world range depends on:

How Much Range Do Electric Bikes Get?

 

Most brands advertise ranges like “up to 60 miles” or “up to 120km,” but real-world range depends on:

  • Rider weight

  • Tyre size and pressure

  • Hills and wind

  • Motor power

  • Assist level used

  • Temperature (cold reduces range)

Realistic Range Estimates

  • 250–400Wh: 15–35 miles (24–56km)

  • 500–700Wh: 25–60 miles (40–96km)

  • 750–1000Wh: 40–90 miles (64–145km)

If you’d like to know a bit more about battery range and the variables that can affect this, the masters of technology, Bosch, have a great guide HERE.


Battery Placement: Why It Matters

Common placements:

  • Down tube battery (best balance)

  • Rear rack battery (less stable, common on older models)

  • Integrated internal battery (clean look, harder to remove)

  • Dual battery systems (best for cargo and touring)


Battery Lifespan

Most lithium eBike batteries last:

  • 500–1000 full charge cycles

That typically equals:

  • 3–7 years depending on usage.


Charging Time

Charging usually takes:

  • 3 to 7 hours

Fast chargers exist but can slightly reduce battery lifespan if used constantly.


Battery Safety: What to Look For

This matters more than most buyers realise.

Look for:

  • UL certification (where available)

  • Name-brand battery cells (Samsung, LG, Panasonic)

  • Smart battery management system (BMS)

Avoid unknown ultra-cheap batteries with no certification.


Sizing, Brakes, Suspension, Legal Classes + Final Checklist

Getting the Right Size Matters

Even the best electric bike will feel wrong if the sizing is off.

General sizing tips:

  • If between sizes, size down for easier control

  • Step-through frames are easier for commuting and cargo

  • Check stand over height and reach, not just height charts


Brakes: Don’t Compromise Here

Because eBikes are heavier and faster than normal bikes, braking is critical.

Mechanical Disc Brakes

Pros

  • Cheaper

  • Easy to adjust

Cons

  • Less stopping power

  • More hand effort


Hydraulic Disc Brakes (Recommended)

Pros

  • Strong stopping power

  • Better in rain

  • Less hand fatigue

Cons

  • Slightly higher cost

If you’re buying a commuter eBike or anything over 500W, hydraulic brakes are strongly recommended.


Suspension: Do You Need It?

No Suspension

Best for: smooth pavement, lightweight bikes
Cheapest and lowest maintenance.

Front Suspension

Best for: rough roads, gravel, comfort
Great middle option for most riders.

Full Suspension

Best for: trails, mountain biking
Usually more expensive and heavier.


Tyres: Comfort vs Speed

  • Narrow tyres = faster, more efficient

  • Wider tyres = comfort, grip, stability

A great “all-around” commuter tyre size is 2.0”–2.4”.


Electric Bike Legality (Important!)

If you plan to ride on the public highway, bike paths or trails, then legally, your ebike should operate a ‘pedal assist’ system comprising a motor that has a continuous rated power not exceeding 250 Watts and only be assisted up to 15.5mph (25kph).


How Much Should You Spend? (Price Guide)

Budget eBikes (up to £1,500)

Good for casual riders, flat terrain
Expect compromises in:

  • brakes

  • battery quality

  • long-term durability

Mid-Range eBikes (£1,500-£3,000)

Best value category
You’ll often get:

  • quality, mid-drive motor (e.g. Bosch)

  • better battery with good range

  • hydraulic brakes

  • good warranty

Premium eBikes (£3,000+)

For riders who want:

  • powerful mid-drive motors

  • longest range battery

  • premium components


Final Electric Bike Buying Checklist

Before buying, make sure you know:

✅ What type of riding you’ll do
✅ Your preferred motor type (hub vs mid-drive)
✅ Battery size in Wh (not just “range”)
✅ Torque rating (Nm) if you live in hills
✅ Brake type (hydraulic strongly recommended)
✅ Total weight of the bike
✅ Warranty length and brand reputation
✅ Local eBike laws and class limits
✅ Availability of replacement parts


Conclusion: The Best Electric Bike is the One You’ll Actually Ride

The best electric bike isn’t always the most powerful or expensive – it’s the one that fits your lifestyle, terrain, and comfort needs.
