Electric bike with trailer: What you need to know when buying and using an EAB

Are you planning an outing and want to take along some luggage or transport children? You can equip your electric bike with a trailer. But which electric bikes are compatible with a trailer, and what regulations need to be complied with? This guide answers these questions. You'll also find out how to adapt your riding to a trailer, what to consider when buying a trailer, and when an electric cargo bike could be an interesting alternative.

• Battery capacity: with a trailer, an electric bike requires more energy, which reduces its range. We therefore recommend a high-capacity battery.
• Total weight When attaching a trailer, the total weight increases. For safety reasons, make sure you do not exceed the maximum permissible weight (including your own weight). Loading limits are generally indicated in the owner's manual.
• Brakes: with greater weight, the brakes must be powerful enough to stop the bike and trailer safely. Consult the manufacturer's recommendations concerning the possible installation of an additional brake (inertia brake) depending on weight.

• Classic trailers are authorized only for electric bicycles with motor assistance not exceeding 25 km/h.
• The weight of the loaded trailer must not exceed 80 kg. This is the total weight (trailer + load). Trailer width must not exceed 1 meter.
• The trailer must be equipped with a rear lighting system if you're driving at night or in poor visibility conditions. This includes a red rear light and a reflector.
• You can transport people in a trailer if it is designed for this purpose (e.g. children's trailer). You may transport up to 2 children in a trailer designed for this purpose. Children must be secured in the trailer with seatbelts.

Driving with a trailer requires you to adapt your driving style. It's a good idea to practise before setting off. Before each departure, check the brakes, the pressure of the tires and the connection between the electric bike and the trailer.

Here are some important points to bear in mind when driving with a trailer:

• Longer braking time: the extra weight increases braking distance. Adopt a more cautious driving style, anticipate situations and avoid sudden braking.
• Increased turning radius: the trailer increases the turning radius. Adapt your speed when cornering, and make steering movements more gradual.
• Tipping hazards: avoid hitting kerbs or crossing potholes, as this could cause the trailer to tip over.
• Increased energy consumption: a trailer increases energy demand. Drive at a moderate, constant speed, and consider carrying a spare battery for long journeys.

The range of bike trailers on offer is vast and depends on the model of your electric bike. It's advisable to seek expert advice and take a test ride before you buy. Before you set off, take a look at our riding tips for beginners.

Here are some important criteria to check when buying an electric bike trailer:

• Make sure the trailer can be securely attached to your electric bike, with a safety cable for added protection, especially if you're transporting children.
• If you often use rough roads, a suspension system is recommended.
• Large wheels enhance ride comfort. Splash guards protect against splashes.
• The parking brake must act on both wheels.
• A children's trailer must be equipped with seat belts, roll-over bars and a front cover to protect from sun and rain.
• Lighting must be adapted to the width of the trailer.

If you frequently transport children or bulky items, you may be wondering whether to use a trailer or invest in an electric cargo bike.
