Electric bikes are one of the most popular ways of commuting in New Zealand. Whether for work travel or leisure, these bikes are highly convenient, practical, good for the environment, and healthier for you. 

For those cycling long distances, electric bikes add an extra boost to your pedalling power, making it more accessible for all types of riders. So, let’s look at some of the important considerations if you’re in the market to buy an electric bike. 

What is an Electric Bike?

An electric bike, or e-bike, is a bicycle equipped with an electric motor to improve its pedalling capacity. Unlike other types of bikes, electric bikes come with power assistance, making it easier to ride up hills and longer distances without straining.  

E-bikes typically found on the market can be divided into city bikes or mountain bikes. City e-bikes are designed for city riding on pavements, while mountain e-bikes are designed for off-road trails. There are also folding e-bikes in the market, lightweight and portable bikes that are ideal for urban commuters with limited storage. 

Key Factors to Consider When Buying an Electric Bike

Battery Considerations

Battery types are highly important when choosing an e-bike, and perhaps the most expensive component. E-bike batteries are usually measured in "watt hours" or voltage. 

Choosing a battery size for your intended use is a big consideration, as smaller batteries may not be enough for a long commute. You may also need to decide between removable and fixed batteries. Removable batteries can be charged conveniently, while fixed batteries are more integrated and sleek.

Motor Types and Performance

Electric bike motors generally come in two main types: hub motors and mid-drive motors. Hub motors, which are divided into front-hub and rear-hub, are more cost-effective and easier to maintain. Meanwhile, mid-drive motors cost more but provide better balance and power, particularly for tackling hills. 

Range and Efficiency

The range of an e-bike depends on factors like rider weight, motor capacity, terrain, and the level of electric assist used. Manufacturers of e-bikes usually provide an estimated range of how much you can travel in a charge, but the actual mileage may vary. However, you can expect a single charge to give you between 32 to 160 kilometer coverage.

Bike Design and Frame Materials

Electric bikes are typically made from aluminium or carbon fibre. Aluminium frames are durable and affordable, while carbon fibre frames are lighter and can accommodate more speed. 

Additionally, you should select the right frame size to ensure the bike fits your height while riding. We highly recommend testing your frame size at a bike shop before purchasing. 

Weight and Portability

The weight of your bike is an important consideration, especially if you need to carry your bike on stairs or lift it onto a rack. Lightweight models made out of aluminium frames are often preferred for commuting. 

If your primary use is in the city, consider foldable electric bikes, which give you excellent portability and can easily be stored in small spaces or on public transport.

Speed and Power Regulations

E-bikes in New Zealand are often limited to a maximum speed of 32 km/h or 45 km/h. Additionally, regulations also state that all e-bike motors must have a maximum power output of 300 watts - however, most motors in the market come with a 250-watt output. Knowing these speed regulations helps you comply with the necessary limits and avoid costly penalties. 

Braking System

E-bikes come with various braking systems, such as quad-piston and dual-piston systems. The quad or 4-piston brakes will give you better braking power, particularly on a descent or steep terrains. Meanwhile, 2-piston brakes are popular for riders travelling on levelled city roads. Recent advancements in breaking technologies have also introduced anti-lock braking systems, such as the Bosch ABS, that prevent your bike’s wheels from locking up and skidding during braking 

Suspension Systems and Ride Comfort

Suspension is a vital part of comfort and control in e-bikes. Good suspension absorbs shocks from bumps, potholes, and uneven terrain while keeping your bike steady, so choosing the right one depends on your terrain. 

The most common type of suspension on e-bikes are suspension forks, which are suitable for city riding and light trails.  Meanwhile, full-suspension bikes are equipped with both suspension forks and a rear shock, giving you better comfort and control on rugged trails.

Gear Systems and Drivetrain

When it comes to gear systems, e-bikes may feature single-speed or multi-speed options. Multi-speed gears are more versatile, especially for riders who encounter hilly terrain, while single-speed systems are ideal for those who want a fuss-free, easy ride. When choosing the right gear, consider the terrain your e-bike is used on and if you enjoy controlling the gears on your e-bike. 

Pedal Assist and Throttle Options

E-bikes have different levels of pedal assist, allowing riders to choose how much assistance or power they receive while riding. Bikes with lower assist levels will give you a light boost on smoother roads, while higher levels are suitable for e-bikes on challenging hills. Some models also come with a throttle, which provides you with the convenience of motor-powered riding without pedalling.

Comfort and Ergonomics

For additional comfort, consider e-bikes with adjustable handlebars and seats that allow you to adjust your riding position. This helps you reduce hand fatigue on longer journeys. Some bikes also offer step-through frame designs, making mounting and dismounting more manageable for smaller riders. 

Key Takeaway

Choosing an electric bike is an important decision that will impact your cycling experience. So take your time to test different models, and always be sure to buy your e-bike from a reputable seller.
