Age range: These are normally categorized by weight rather than age, but I would say they’re suitable for kids between roughly one and four years old. You can get single or double trailers, with some of the better quality models taking around 30 kilograms. As they have a hood, it’s a good idea to test-ride for older children to check there’s enough head room when it’s pulled down.

How do they attach? Trailers come with a hitch that bolts on to the hub of the rear wheel; the arm of the trailer then clicks into the hitch, and a safety strap connects to the frame and the trailer arm. They usually come with a brightly coloured flag that extends up from the trailer to improve visibility.

Pros:

• The double-seated trailers can transport two children and often have space for shopping.

• They are covered, so your child is protected from rain, wind and sun.

• You don’t feel the weight as you would with a child on a rear seat on the bike, which also makes it easier to balance and less hard work.

• You can attach it to your own bike rather than forking out for a cargo bike.

• Getting your kids in and out is easier and involves less lifting.

• Children have more space than on a bike seat, so can bring a teddy, blanket or snack and get comfy.

Cons:

• Your children are low down and behind you, so it doesn’t feel quite as safe and reassuring as having them up front in full view.

• Detaching and folding down the trailer can be a chore.

• You need to take extra care going downhill as the weight behind you can propel you forward.

• Some of the cheaper models don’t have much suspension, so it can be a bumpier ride for your little ones.

• Kids can get up to mischief or squabble, as they are in their own little den and Mum is busy cycling.

The test ride: I used a trailer for a month when visiting the US. My daughter was two and, despite me feeling nervous about her being both behind me and somewhat separated from me, it actually worked very well. She loved it, as it was her little domain, and it was surprisingly smooth and easy to cycle with. I did have the luxury of cycling on very wide, straight and quiet residential roads, and a garage to store it in – a luxury I don’t have living in a city flat. However, if I ever had two little ones, I would consider a trailer, especially for colder, rainier times of year.
