What Is an Electric Bike? A Beginner’s Guide to Assistance, Range and Riding in Europe

An electric bike, or e-bike, is a bicycle fitted with a battery, motor and control system that can provide power while you ride. On some bikes, the motor only assists when you pedal. Others also have a throttle. Both may be described as electric bikes, but they do not necessarily work in the same way or fall under the same road rules.

The difference is often easiest to feel when you set off or reach a hill. You still steer, change gear and brake. The motor simply takes on some of the effort, depending on the bike, the assistance level and how you are riding.

How does an electric bike feel different from a regular bike?

A regular bike moves through your own pedalling. On an electric bike with pedal assistance, a sensor detects that you are pedalling and the motor provides support. Increase the assistance and a climb may feel easier; turn it down and you do more of the work yourself.

Not every system responds in the same way. Some sensors detect whether the pedals are turning, while others also respond to how hard you push. Two bikes with similar motor figures can therefore feel quite different when pulling away or riding slowly through a turn.

There are practical differences off the bike, too. Electric bikes are generally heavier than comparable non-electric bikes, need charging and have electrical components to look after. If you carry your bike upstairs every day, its weight may matter more to you than its maximum assisted speed.

What should you notice on your first ride?

Find a safe, open place where you are allowed to ride, and start with a low assistance setting. You do not need to memorise a specification sheet first. Pay attention to three things:

  • When you start pedalling: How soon does the motor respond, and is the power easy to control?
  • When you ease off or prepare to stop: How does the assistance change? Can you slow down smoothly and stop where you intended?
  • On a gentle incline: What changes when you adjust the assistance? Is it easy to combine the motor’s help with changing gear?

If the bike has a throttle, learn how that works separately. A comfortable test ride tells you whether you like the bike’s response; it does not establish which road rules apply to that vehicle.

What is the difference between pedal assistance and a throttle?

With pedal assistance, the motor helps while you pedal. A throttle lets you request motor power using a hand control. Some bikes offer both.

That distinction affects how a bike rides and may affect how it is classified. A setting that stops motor assistance at 25 km/h does not, by itself, tell you everything you need to know about the bike’s legal status.

An assistance cut-off is also different from a speed limit on the wheels. Once the motor stops helping, you may still travel faster by pedalling or going downhill.

What do W, Wh and 25 km/h mean on a specification sheet?

Figure

What it tells you

What it cannot tell you on its own

Motor power (W)

How the motor’s power is stated

How the bike will feel on a hill, or how it is classified. Check whether the figure refers to peak power or maximum continuous rated power.

Battery capacity (Wh)

How much energy the battery can store

The exact distance you will get from a charge.

Assistance cut-off (km/h)

The speed at which the motor is set to stop assisting

The fastest the bike can travel, or whether it qualifies for a particular set of road rules.

Peak power and maximum continuous rated power are different measurements. When comparing bikes, check which one the manufacturer has provided. A large number on its own gives you little sense of how the bike will respond on your usual route.

How far can an electric bike go on one charge?

A published range is a useful starting point for comparison, but it is not a promise for every journey. A flat ride on low assistance will place different demands on the battery from a hilly ride with luggage and frequent stops. Rider weight, temperature and tyre pressure can also make a difference.

For a regular commute, start with your return distance, the hills on your route and where you can charge. Then allow some margin for a change in weather or an unexpected detour. That is more useful than planning every trip around the highest advertised range.

Range is also different from battery lifespan. Range is the distance you may cover on a charge; lifespan concerns how the battery holds up over time. For a closer look at charge cycles and signs of wear, read How Long Does an E-Bike Battery Last?.

Can every electric bike be used like a regular bicycle in Europe?

The name “electric bike” is not enough to determine that. EU Regulation No 168/2013 excludes a particular type of pedal-assisted cycle from its vehicle type-approval requirements. Among its conditions, the auxiliary motor must have a maximum continuous rated power of no more than 250 W. Motor output must stop when the rider stops pedalling, and otherwise reduce progressively before cutting off before the bike reaches 25 km/h.

These conditions need to be considered together. Setting a bike’s assistance cut-off to 25 km/h does not automatically place it in that excluded category. Where a bike’s power or method of propulsion differs, its classification and use need to be checked against the documentation for that particular model and the rules in the country where it will be ridden.

If you plan to ride on public roads, ask the seller for the model’s precise specifications and relevant documentation. Do not rely on a speed setting or a single motor figure to make that decision.

How do you choose your first electric bike?

Begin with what you actually do each week:

  • You carry the bike or combine riding with public transport: Check its total weight and folded size, if it folds. Make sure you can lift and move it yourself.
  • You regularly climb hills or carry luggage: Try setting off at low speed, changing gear and braking. The bike should feel manageable in each situation.
  • You have a longer return journey: Work out the distance on your own route and where you can charge, then leave room for less favourable conditions.
  • You intend to use public roads: Check the model’s propulsion system, maximum continuous rated power, documentation and the rules where you ride.

Fit matters as much as the motor. Two bikes with the same wheel size may suit different riders because their frame length, saddle adjustment and step-over height differ. If you are unsure where to begin, use our guide to choosing the right e-bike size, then compare its advice with the dimensions of the bike you are considering.

Once you know what you need, you can explore the Vitilan electric bike range. Check each model’s own specifications and documentation; bikes within the same range may have different equipment and operating characteristics.

Frequently asked questions

Can you ride an electric bike when the battery runs out?

If the bike has a working pedal drivetrain, you can generally continue under your own power. It may take considerably more effort than riding a regular bike, particularly uphill or with luggage.

Is riding an electric bike still exercise?

If you are pedalling, you are still physically active. The amount of effort changes with the assistance level, terrain and how you choose to ride. A journey made using a throttle may involve much less pedalling, so it would be misleading to treat every e-bike ride as the same.

Does a 25 km/h setting mean an electric bike can be used on European roads?

Not on its own. You also need to check the motor’s maximum continuous rated power, how it responds when pedalling stops, how any throttle works, and the documentation and rules relevant to the specific bike and location.

An electric bike adds an electric drive system to a vehicle you still need to control. Before choosing one, find out when the motor helps, whether the range suits your route, whether the bike fits you, and where that particular model can be used.
