What is an electric cargo bike?

The main types of electric cargo bike

Cargo bikes come in a few distinct layouts. Each handles differently and suits different loads.

Load ratings and what they mean

Every cargo bike has a maximum load, usually given in kg. It may refer to the total of rider and cargo, or to the cargo area alone, and the rear rack often has its own lower limit. Read the specification carefully and check each figure separately.

Carrying children needs suitable seats or a box with harnesses designed for the bike, and the maker's guidance on ages and weights. Heavy loads also make brakes work harder, so good hydraulic disc brakes are important.

How the motor helps

Cargo e-bikes usually use mid-drive motors with high torque, which use the gears to help with heavy loads on hills. They still have to meet the EAPC rules for UK road use: a motor rated at no more than 250 W continuous, assistance stopping at 15.5 mph and no throttle above walking pace.

Because loads use more energy, battery capacity matters. Some cargo bikes have room for two batteries. Our range explainer shows how weight affects range, and our battery size guide helps with sizing.

Riding a loaded cargo bike

A loaded cargo bike handles differently from an ordinary bike. It takes longer to stop, needs wider turns and can feel top-heavy when you are wheeling it or stopping on a camber. Practise somewhere quiet with an empty bike first, then with a light load, before carrying children or heavy shopping in traffic.

Use a low gear and a moderate assist level when setting off with a load, so the motor does not surge. Most cargo bikes have a sturdy centre or double-leg stand; always use it when loading and unloading, and keep your hands on the bike while children climb in or out.

Storage and security at home

Cargo bikes are long and heavy. A longtail may be around two metres long, and front-loaders are often longer. Before buying, measure your storage space, gate and path, and think about whether you can turn the bike into it. Many UK homes use a secure shed or bike store, but a battery should be brought indoors to charge.

A cargo bike is valuable and a target for thieves, so use a strong lock to a solid anchor and consider insurance. Our heavy-duty lock guide and our explainer on e-bike insurance cover this.

Note:Lithium battery safety: charge only with the charger supplied for your battery, do not leave it charging unattended or overnight while you sleep, charge away from escape routes such as hallways, and stop using any battery that is swollen, cracked, leaking, very hot or smells odd. See the London Fire Brigade guidance on lithium batteries.

Cargo e-bike or trailer?

A trailer behind an e-bike you already own can carry children or shopping without a second large bike to store. It is easier to fit in a small home, since the trailer can fold, but it makes the combination longer and wider on the road.

Our cargo e-bike vs bike trailer comparison goes into detail, and our bike trailer guide covers trailers suited to e-bikes. You can also browse the cargo e-bikes section.

Frequently asked questions

What is the difference between a cargo bike and an e-cargo bike? An e-cargo bike has a motor and battery to help you pedal. A standard cargo bike relies on your legs alone.

Do you need a licence for an electric cargo bike? Not if it meets the EAPC rules and the rider is at least 14. See gov.uk.

How much can an electric cargo bike carry? It depends on the model. Check the maximum total load and the cargo area limit in kg in the specification.

Are electric cargo bikes hard to ride? Longtails feel close to a normal bike. Front-loaders take a short time to get used to because the steering feels different.
