How to Choose the Right Cargo Bike

When you chat with us - whether in the shop or online - we’ll
usually start by asking two simple questions:

Where do you ride? Do you tackle a big hill, cruise a long flat commute, or a bit of both?

What do you carry? Is it cargo, kids, or a mix of everything?

Big hills usually mean more power and stronger brakes. Long commutes might call for a high-speed option with a larger battery. Carrying kids or heavier gear means looking at stability and the right accessories.

It can feel overwhelming with so many models out there, but that also means there’s a perfect match for your lifestyle. We’ll help you find it - and you can take an extended test ride to make sure it really fits into your day-to-day.

If you want to explore yourself on our website, go to our cargo bike page and use the filters to narrow down your options based on how you answered the questions above.

Most longtail cargo bikes are set up to carry two kids on the back, like the Tern GSD or Specialized Porto. The popular Yuba Spicy Curry can carry three!

Front-loading cargo bikes can fit two or three passengers up front. Each bike can be customised with heaps of accessories -seats, footrests, baskets, rain covers - so we’ll help match the setup to your crew.

Non-electric cargo bikes are fine for flat, short trips with lighter loads. But if you’ve got hills, longer distances, or wriggly kids on board, an e-cargo bike will change your life. The motor takes the sting out of climbs, makes heavy loads manageable, and opens up bigger commutes without breaking a sweat.

Most e-cargo bikes will happily take you 40–80 km on a single charge. Your range depends on the terrain, assist level, and how much you’re carrying. Some models run dual batteries, which basically doubles your distance - handy for all-day missions.

Absolutely.

Cargo bikes are designed with families in mind. Add the right accessories - child seats, harnesses, rain covers - and they’re one of the safest, comfiest ways to get kids around town.

And the best part? Kids love the ride.

For a lot of families, yes.

Cargo bikes take care of school runs, shopping, work commutes, even weekend adventures. Many of our customers have sold their second cars and never looked back - some have even sold both! You can haul kids, groceries, pets, or gear without the fuel bills or parking headaches. Some households even call the cargo bike their “first car,” keeping the actual car for long trips and holidays.
