What to Look for When Buying an Electric Bike: A Complete Buyer’s Guide

What to Look for When Buying an Electric Bike: A Complete Buyer’s Guide

Buying an electric bike is exciting, but with so many models and features, it can also feel confusing. Many first-time riders worry about picking the wrong motor, choosing a battery that won’t last long enough, or ending up with a bike that feels uncomfortable after just a few kilometres. The truth is that choosing the right e-bike becomes much easier once you understand the main features that affect your ride.

Across Australia, more people are choosing e-bikes to replace short car trips, cut fuel costs, and enjoy easier movement around their communities. Whether you plan to ride to work, explore local paths, or run errands, an electric bike can make riding more enjoyable and practical.

At Macarthur e-Bikes, they’ve helped hundreds of riders find the perfect e-bike for their lifestyle. This guide breaks everything down clearly so you know exactly what to look for when buying an electric bike and how to avoid common mistakes.

Motor Types and Power: What Suits Your Riding Style

The motor is the heart of your electric bike. It determines how the bike feels, how well it climbs hills, and how much support you get while pedalling.

Hub Drive Motors

Hub motors sit in the centre of either wheel. They are:

  • Reliable
  • Easy to maintain
  • Affordable

Rear-hub motors deliver smooth, steady power that’s ideal for commuting and riding on flat paths. If you mainly ride around town and want a budget-friendly choice, a hub-drive bike is a solid fit.

Mid Drive Motors

Mid-drive motors sit between the pedals and use your gears to give power. They feel natural and handle hills extremely well. Riders choose mid-drive bikes when they want:

  • Better hill-climbing
  • Strong torque
  • A natural cycling feel

These models are great for hilly suburbs, longer commutes, and riders who want higher performance.

Choosing the Right Power Output

Most road-legal e-bikes in Australia fall around 250 W for pedal-assist use. This is plenty for commuting and everyday riding. More powerful bikes, like 500–750 W models, are often chosen for:

  • Steep hills
  • Extra load (backpacks, groceries)
  • Off-road riding
  • Longer weekend adventures

Just make sure the motor size matches your riding conditions and local regulations.

Battery Size and Range: How Far Will It Take You?

The battery determines how long you can ride before needing to recharge. Bigger batteries provide longer range, so you can ride further with confidence.

Capacity is measured in watt-hours (Wh).
 Here’s a simple guide:

  • 500 Wh: 40–80 km
  • 700+ Wh: 60–120 km

Actual distance depends on:

  • Terrain
  • Rider weight
  • Assist level
  • Tyre type
  • Wind and hills

Before choosing, ask yourself:

  1. How far do you ride on a normal day?
  2. Do you encounter steep hills?
  3. Will you rely heavily on pedal assist?

A good rule is to choose slightly more battery than you think you need, so you always have extra range for unexpected trips.

Frame Style and Fit: Comfort Comes First

A bike should feel good from the moment you sit on it. If the frame doesn't fit properly, riding will feel awkward or even painful.

Step Through Frames

These frames have a low entry point, making it easy to get on and off the bike. They’re great for:

  • Commuters
  • Riders with mobility concerns
  • Anyone who wants a relaxed upright position

Traditional Frames

These offer a more sporty riding position. They suit riders who prefer:

  • Speed
  • Stability
  • Performance riding

Choosing the Right Size

A test ride is the best way to check comfort. If that’s not possible, follow the height chart provided by the brand. A properly fitted bike helps you ride longer without strain.

Brakes, Suspension, and Safety Features

Electric bikes go faster and often carry more weight, so quality safety features matter.

Disc Brakes

Hydraulic disc brakes are the gold standard. They offer:

  • Strong stopping power
  • Smooth control
  • Reliable performance in wet weather

Mechanical disc brakes work too, but require more effort.

Suspension Systems

Suspension makes a big difference on rough paths.
Choose:

  • Front suspension for everyday comfort
  • Full suspension for off-road riding

If you ride only on smooth paths, you may not need suspension at all.

Built-In Lights

Integrated LED lights powered by the main battery improve safety and remove the hassle of recharging separate lights.

Tyre Types and Terrain

Tyres affect stability, grip, and comfort more than most people realise.

Road Tyres

  • Smooth
  • Lightweight
  • Fast rolling

Best for city paths and sealed roads.

Hybrid Tyres

  • Light tread
  • Good grip on varied surfaces

Perfect for riders who switch between paths and gravel.

Fat Tyres

  • Wide
  • Shock-absorbing
  • Extremely stable

Ideal for riders who want comfort on gravel, sand, grass, or rough surfaces.

Weight, Portability, and Storage

Electric bikes weigh more because of the motor and battery. Some weigh around 22 kg, while others can reach 30+ kg.

If you:

  • Live in an apartment
  • Transport your bike in a car
  • Have limited storage

you may want a lighter or compact model. Removable batteries also make indoor charging much easier.

Displays, Controls, and Tech Features

Good e-bike displays should be clear and simple. Essential information includes:

  • Speed
  • Battery life
  • Distance
  • Assist mode

Extra features like Bluetooth apps, GPS tracking, or ride analytics are nice bonuses, but they shouldn’t be the main factor when choosing a bike. Reliability and comfort come first.

Price, Warranty, and After-Sales Support

Price varies depending on quality, motor type, range, and brand. Cheaper e-bikes are tempting but often lack:

  • Strong brake
  • Durable batteries
  • Reliable components
  • Long-term support

A good warranty protects your investment. Look for coverage on:

  • Frame
  • Battery
  • Motor
  • Electronics

Buying from a trusted local seller also means easier servicing and access to real support.

Real Products from Macarthur e-Bikes That Fit These Needs

To make all these features easier to understand, here are two popular models from Macarthur e-Bikes that match different rider needs.

Ampd Bros ACE-S Plus+ — The Comfortable All-Rounder

The ACE-S Plus+ is one of our most popular step-through e-bikes. It comes with:

  • A strong 750 W motor
  • A powerful 52 V battery
  • Up to 80 km of real-world range
  • Wide fat tyres for stability
  • An easy step-through frame

This bike is perfect for riders who want confidence on mixed terrain. Fat tyres help smooth out bumps, making it great for riders who want comfort above all else. With its strong motor and battery, the ACE-S Plus+ suits daily commuting, weekend exploring, and carrying extra load.

It’s one of the best examples of how a well-built e-bike can make riding feel effortless.

Mamba Venom 48V 750W — Built for Power and Distance

If you want something stronger, the Mamba Venom is a powerful option built for longer rides and tougher conditions. It features:

This bike is ideal for riders in hilly areas or those who need extra support carrying gear. The Venom offers a performance-focused feel and strong acceleration, which is great for riders who want serious capability instead of a simple commuter bike.

Why Test Riding Matters

Specs tell part of the story, but riding the bike tells the rest. A test ride helps you understand:

  • How the motor responds
  • Whether the size fits
  • How comfortable the seat and bars feel
  • How stable the bike is

We always encourage riders to try multiple models. Often, the "right" bike becomes clear the moment you ride it.

Common Mistakes Buyers Make

Avoid these errors:

  1. Choosing based on looks instead of comfort.
  2. Picking a motor too weak for local hills.
  3. Underestimating battery size.
  4. Buying from sellers without proper support or spare parts.

If you avoid these mistakes, you’re far more likely to enjoy your e-bike for years.
