Choosing an electric family bike: longtail vs box bike vs trike

A family bike quietly changes how you get around London — the school run, the shops, the weekend trips out, all done on two wheels (or three) and usually with more fun than the car. Choosing the right one is more straightforward than it looks: it comes down to a few practical things — how many children you carry, where the bike will live, your route and your budget. This guide walks through the three main styles — longtail, box bike and electric trike — and what's worth weighing up at home and on a test ride. Most of us here ride these ourselves, school run included, so we know how they behave loaded, in the rain, on the mornings you're already running late.

Which family bike style is right for you?

In short: a longtail rides closest to a normal bike and is the easiest to store; a box bike carries the most and keeps children in front where you can see them; a trike is the steadiest at low speed and when stopped. Which one suits you usually comes down to how many children you carry and where the bike will live.

Types of family bikes

Each style is genuinely good at something, and the right one for you comes down to what you carry, where you'll keep it, and how you like to ride.

Box bikes (bakfiets, Long John, front-loaders)

A box bike — a bakfiets, in Dutch — is a front-loading cargo bike that carries children in a box ahead of the rider, in full view and part of the conversation. They're longer than a standard bike, but the long wheelbase and low centre of gravity keep a full box feeling planted rather than precarious, even with a restless passenger or two.

If you're carrying two or three children, a box bike is usually the one that wins people over. Everyone rides up front where you can see and talk to them, most come with a bench and seatbelts, and some front-loaders will take a young baby in an approved infant carrier — a Maxi-Cosi adapter, typically — which gets you back on a bike sooner than you might expect. The catch is size: the real question usually isn't which box bike, but where it'll live and how it'll get there. Overall length and turning circle decide more of these purchases than anything on the spec.

Box bikes in our range include the Urban Arrow FamilyNext and the Riese & Müller Load5 and Packster2 70 CT — see the full Urban Arrow and Riese & Müller ranges.

Longtail family bikes

A longtail is a cargo bike with an extended rear rack for passengers, kept close to the length of a normal bike — so it rides much like one you already know and stores more easily than a front-loader. You'll also hear them called midtails — strictly, a midtail is just a shorter, more compact longtail, and in practice the two terms are used interchangeably. Longtails are a common choice in London: compact enough to keep at home, and easy to filter through traffic.

For one or two children, a longtail is the one we reach for most often. It rides like a bike you already know, so the learning curve is short, and it's the style most likely to fit down a London hallway or into a bike hangar. The setup grows with your children, and some models will take an adult on the back too. Worth knowing before you commit: capacity varies by model, and a full bike feels different at low speed until you've got the hang of it — usually about a day. The accessories that make a longtail properly family-ready (safety rails, seats, footrests, panniers) add width, weight and a little cost, so it pays to spec the whole thing, not just the bike.

Longtails in our range include the Tern GSD, the Riese & Müller Multicharger3 and Multitinker2, and the Veloe Multi; the compact Tern HSD sits at the midtail end of the range, for tighter spaces. See the full Tern and Riese & Müller ranges.

Family trikes

A trike earns its place on stability. Three wheels mean it stays upright when you stop, so there's no balancing act while you load children or wait at the lights — welcome if you'd rather not manage a loaded two-wheeler at all. It won't lean into corners the way a bike does, and it's heavier, but a full load feels just as planted as an empty one.

That makes a trike a solid platform for heavier everyday loads: several children, the bags and shopping that travel with them, and on some models an adult passenger too. The trade-offs are honest ones. Trikes are wider, so measure your gates, sheds and access points before you commit. They're heavier, so make sure there's enough motor torque if you're somewhere hilly. And while it holds its footing at walking pace, that confidence eases off at speed — so if your routes include long descents, pay attention to the brakes.

Our family trikes come from Black Iron Horse and Mäx & Mäleon.

Choose by passenger count

If you'd rather start from the simplest question — how many children am I carrying — begin here.

For one child, the best bike is the one you'll actually use every day: easy to get on and off, easy to park, easy to store. Plenty of families like a longtail for its familiar feel; a box bike adds the “up front” experience and room to grow into.

Two passengers change how a bike feels — the combined weight is real, so good brakes, tyres, motor and gearing, solid passenger accessories and weather protection all start to matter more. Where storage allows, many families find a box bike works well, with children up front where you can see them; a well-specced longtail does the job just as happily.

At three children you're close to purpose-built territory. There are fewer options, and box bikes, trikes and heavy-duty longtails tend to make the most sense. Stability, power, durability and room to grow become the things that decide it.

Four or more passengers is specialist territory, and this is where purpose-built trikes come into their own — steady at stops, settled at low speed, and built for the heaviest loads.

Storage and access

This is the bit most people skip, and the bit that most often decides things. Before you fall for a particular bike, measure your narrowest gate or doorway, walk the tight turns — hallway corners, stairs, the awkward bit by the front door — and be honest about where it'll actually live: shed, front garden, hangar, side return. A full-size box bike can be around 2.6m long, and a trike is wider than most gates expect, so storage tends to rule options out faster than any spec ever will.

Keeping your family bike secure

Keeping a family bike secure is simpler than it might seem, and it's something we're happy to sort out with you. Most of it comes down to two things: the right lock and where the bike is kept. For a bike of this value, we'd point you towards a lock rated to resist an angle grinder — it's the upgrade that makes the real difference. A fixed anchor point and a settled home such as a hangar, garage or off-street spot do the rest; a bike that's tucked away and properly locked is a far less appealing prospect than one left out on the street. Many owners insure their bike for peace of mind as well, at home and out and about — we usually suggest Laka — and when you collect it we're glad to talk through a setup that suits where you live.

Passenger setups and weather protection

A family bike is only as good as the setup around the passengers, and that's mostly down to the accessories:

Seats or bench seating — matched to age and stage; seatbelts are worth having from the start.

Rails or handholds — so passengers feel secure; double rails also protect small hands in a fall.

Foot support and wheel or leg guards — ideally part of the bike, not a line on the invoice.

Weather covers — for riding through a London winter; UV-resistant or recycled materials tend to last.

Bags or panniers — so the whole day doesn't end up in one rucksack on your back.

Tell us your children's ages and we'll sort out what's right for now and what you'll want next — the aim being everyone safe, dry and reasonably cheerful.

Safety, durability and peace of mind

A family bike does a harder job than an ordinary one: more weight, more momentum, and passengers on board who matter more than any pannier of shopping. The bikes we stock are built for exactly that, with frames, brakes, motors and passenger systems designed around carrying children and cargo from the outset. You'll sometimes see DIN 79010 mentioned — it's the cargo-bike testing standard, with load limits of 250kg for two-wheelers and 300kg for trikes, and brake, frame and child-passenger tests well beyond those for an ordinary bike. A standard isn't the whole story, but it's a fair sign a bike has been designed and properly tested for the job.

Our honest advice: test before you decide

The right family bike is simply the one that leaves you confident and comfortable — and you'll learn more in ten minutes of riding than in an afternoon of reading. When you come in for a test ride, try to:

Ride two styles back to back — a longtail against a box, say; the difference is obvious in a way it never is on paper.

Notice the small things — how it starts and stops, how steady it is slow, how the kickstand behaves with a load on.

Go round twice — the first lap is usually nerves; the second is when you actually feel the bike.

Think past the ride — where it'll live, how it parks, whether it clears your gate matters as much as how it rides.

Bring the children if you can — it's often their reaction that makes the decision easy. Come in and we'll talk through what suits your routine.

Frequently asked questions

A longtail carries children on an extended rear rack, behind the rider, and stays close to the length and feel of a normal bike — so it's easier to store and to ride if you're new to cargo bikes. A box bike carries them in a box in front of the rider, in full view, with more room and a very stable, low-slung feel — but it's longer and needs more storage space. As a rule of thumb: longtail for compactness and a familiar ride, box bike for capacity and keeping children in sight.

Very little, and the terms are often used interchangeably. Both carry passengers on an extended rear rack behind the rider. Strictly, a midtail is a shorter, more compact longtail — easier to store and manoeuvre, and usually best for one or two children — while a full-size longtail carries a little more and covers ground more comfortably on longer rides. If you're searching for a “midtail”, you're looking at the compact end of our longtail range.

A bakfiets (Dutch for “box bike”) is a front-loading cargo bike that carries children or cargo in a box ahead of the rider. It's also called a Long John or front-loader. The children sit low and in view, which makes the bike stable and the ride sociable.

Often earlier than people expect — it depends on the bike and setup. Some front-loaders can carry a baby with an approved infant carrier (such as a Maxi-Cosi adapter); most child and bench seats suit a child who can sit up and hold their head steady. For older children, manufacturer-approved passenger kits replace child seats, provided they include secure seating, foot support and wheel guards.

Not always — plenty of families ride acoustic, especially for shorter, flatter routes with one child. But once you're carrying two children, a laden pannier or two, and tackling London's hills and stop-start traffic, assist is what stops the ride turning into a workout. It also solves the thing most new cargo riders worry about first: pulling away smoothly from a dead stop with a full load, rather than wobbling off the mark.

It varies by model: some setups are for one child, many carry two comfortably, and specialist bikes take three or more. Box bikes and trikes usually offer the most room — some trikes carry up to six with the right configuration — though a heavy-duty longtail can carry a lot with the right accessories.

The one that fits your route and storage and feels comfortable with your children aboard. A short test ride usually settles it: box bike (children up front), longtail (children behind), or trike (steadiest at stops).

Most people have the hang of it inside a few minutes. A loaded bike feels different at low speed at first, but the low centre of gravity on a box bike, or three planted wheels on a trike, make them steadier than they look. A test ride — ideally two — is the quickest way to feel it for yourself.

Two things matter most: an angle-grinder-rated lock and a fixed anchor point at home — a hangar, garage or off-street spot is best. Most owners insure against theft and damage too; we recommend Laka and can help you set it up when you collect.

Often, yes — many employers' schemes can be put towards a family or cargo bike. Rules and limits vary by provider, so check what your employer's scheme allows, and see our Cycle to Work page or ask us if you'd like help.

Yes — and honestly, please do. Family bikes can look similar on paper and ride very differently: how they set off, turn and stop, and how comfortable your passengers are. Even a short ride puts things in perspective.
