What You'll Learn

Motor and battery wattage
The battery is a crucial component of an electric bike, and its wattage determines the power delivered to the motor and the amount of assistance provided. Batteries with a lower wattage will provide less power, while those with a higher wattage will offer more torque and range. Batteries for electric bikes typically range from 200W to 550W. The ampere rating (Ah) or watt-hour rating (Wh) of the battery will influence how far the bike can travel on a single charge, depending on factors such as terrain, rider weight, and weather conditions. For example, a 10Ah or 375Wh battery will provide an approximate range of 27-35 miles, while a 16Ah battery will offer around 60-70 miles.
It is important to consider the cost of replacing the battery and ensure that it comes with a warranty. Lithium-ion batteries are commonly used in electric bikes and typically last for about three years before performance starts to deteriorate. New batteries can be expensive, often costing around £300 or more. Therefore, it is advisable to factor in the cost of replacement when purchasing an electric bike.

Bike type and use
When choosing an electric bike, it is important to consider your needs and the type of riding you plan to do. Electric bikes come in a variety of designs, from commuter-friendly hybrids to folding models, e-mountain bikes, and even cargo bikes.
If you're looking for a versatile option that can handle both city riding and off-road trails, an electric mountain bike (e-MTB) could be a good choice. These bikes are designed with a comfortable upright riding position and fast-rolling wheels, making them ideal for commuting and tackling country lanes, canal towpaths, and trails. They also often come with a rear rack and mudguard mounts, adding to their practicality for daily use.
On the other hand, if you're looking for a more compact and portable option, a folding electric bike might be a better fit. These bikes are easy to store and transport, making them convenient for commuters or those with limited space. Folding bikes typically have smaller wheels, which can make for a bumpier ride, but they are highly manoeuvrable and can be easily stowed away when not in use.
Another option to consider is the hybrid electric bike, which combines the features of road and mountain e-bikes. Hybrid e-bikes typically have mid-width but large rugged tyres, a lightweight frame, and comfortable riding geometry. They are a good choice if you want a versatile bike that can handle both road and light off-road riding without sacrificing comfort.
For those who need to transport cargo, an e-cargo bike might be ideal. These bikes have larger frames with dedicated storage areas, making them perfect for running errands, carrying groceries, or even taking your children to school. They are a great car alternative for those looking to reduce their carbon footprint without sacrificing functionality.
When choosing an electric bike, it's also important to consider factors such as battery wattage, motor placement, and control systems. The battery wattage will determine the range and power of your electric bike, with higher wattage batteries providing more torque and range. The motor can be placed near the pedals, in the front wheel hub, or in the rear wheel hub, each offering different advantages in terms of power transfer and handling. Control systems can vary as well, from handlebar-mounted computers to smartphone apps, allowing you to customise your assistance level and riding experience.

Size and comfort
When choosing an electric bike, size and comfort are key factors to consider. The size of the bike will depend on your height and inside leg measurement. A comfortable bike will allow you to ride for longer and get more enjoyment out of your purchase.
A good way to test the comfort of an electric bike is to test ride it. Some retailers will allow you to test ride various models in-store, which can be invaluable for assessing the bike's comfort and suitability for you.
The size of the bike's wheels will also impact the comfort of your ride. Generally, larger wheels will provide a smoother ride, with 26" or 24" wheels being better for trails, and 700c or 28" wheels better for road use. However, the width and tread of the tyre will also impact the smoothness of your ride.
The type of motor and drive system can also impact the comfort of your ride. Crank-driven motors are located in the middle of the bike frame and are activated by the rider pedalling, which can provide a more intuitive riding experience. Hub-driven motors are located inside the front or rear wheel hub and provide power on demand, which can be useful for getting away from traffic lights or cycling up hills.
The battery is another important consideration when choosing an electric bike. Batteries come in a variety of wattages, which will impact the range and assistance provided by the motor. A higher wattage battery will give you more torque and range, but may also add to the weight of the bike, impacting the comfort of your ride. It's also important to consider the cost and lifespan of the battery, as well as the ease of replacement.
Finally, the style of the bike can also impact the comfort of your ride. For example, step-through bikes are easier to mount, while mountain bikes are great for off-road use, and folding bikes are portable and space-saving. Electric bikes also come in hybrid models, which combine the features of road and mountain bikes, offering comfortable riding with a lightweight frame and large rugged tyres.

Rules and regulations
Electric bikes (e-bikes) are a fun, sustainable and efficient way to travel. However, as their popularity grows, so does the complexity of the rules surrounding their use. Here is a detailed guide to the rules and regulations of e-bikes in the UK.
- Age restrictions — You must be aged 14 or above to ride an electric bike in the UK. This rule applies to England, Scotland, Wales and Northern Ireland. Children under the age of 14 can ride e-bikes manufactured specifically for children, but only on private land with the landowner's permission.
- EAPC regulations — Most e-bikes in the UK fall within the 'electrically assisted pedal cycle' (EAPC) classification. E-bikes that meet EAPC regulations are considered bicycles and are governed by the same rules and regulations as traditional bicycles. They do not need to be registered, taxed or insured. You also do not need a licence to ride an EAPC e-bike.
- Speed and power restrictions — E-bikes that comply with EAPC regulations must have a maximum power output of 250 watts and a maximum speed of 15.5 mph (25 km/h). The electric assistance must cut off when the bike reaches this speed, but you can pedal faster than 15.5 mph. E-bikes that exceed these limits are classed as mopeds or motorcycles and must be registered, taxed and insured. You must also wear a crash helmet and have a driving licence to ride them.
- Twist and go throttles — E-bikes with a 'twist and go' throttle that can be propelled without pedalling do not comply with EAPC rules and are considered motor vehicles. They are subject to the same rules as mopeds and must be taxed and insured. You must also have a driving licence and wear a helmet to ride them.
- Lights and reflectors — E-bikes must have a white light on the front, a red light on the rear and amber pedal reflectors, just like traditional bicycles.
- Modification and imported parts — It is illegal to modify e-bikes or use imported parts that do not comply with UK regulations. This can pose significant safety risks, especially when charging batteries.
- Transporting e-bikes — You can transport e-bikes on trains, provided they are similar in size to traditional bicycles. However, you may need to reserve a spot in advance. Foldable e-bikes can be taken on buses, following the same rules as traditional foldable bicycles. E-bikes are not allowed on the London Underground or any TfL transport or stations.
- Cycle lanes and pavements — E-bikes that meet EAPC regulations can be ridden on cycle lanes and anywhere else traditional bicycles are allowed. They are not permitted on pavements unless they are designated for mixed cycle and pedestrian use.
