Children’s bike seats: Which are best? Hamax Siesta vs Hamax Amaze

Cycling is one of the best ways to enjoy your sights and surroundings, and whether you’re exploring an exciting urban city or pedalling across the uninterrupted countryside, getting on a bike and adventuring the great outdoors is a healthy and family-friendly activity. 

But what about the little ones? Long rides and tricky terrain can prove tiring for smaller legs, so if you’re planning on going on a more substantial journey or even a cycling holiday, it always helps to invest in a child bike seat.

With so many children’s bike seats out there, the choice can be a little bewildering – and how do you know whether the seat is the right choice for your child? To help, we’ve highlighted different types of bike seats as well as two top-selling products, their benefits and our own recommendations on which bike seat you should buy. 

What to look out for

Kids bike seats are the best way to get out and about on your bicycles safe in the knowledge that your child is both comfortable and well-protected throughout the journey. 

Most bike seats are designed for children aged between nine months and four years of age, though there are different criteria that need to be evaluated when choosing at either end of the scale.

When seating kids towards the lower age limit, you should consider their ability to sit upright unsupported. This will determine which design of bike seat you should buy; be that a reclining seat that’s suitable for children who are too young to sit up without support, or a more standard, upright style. 

Bike seats for children towards the upper age limits are determined by weight; this weight limit is typically around 20-22kg. It’s vital that, in order to comply with the bike seat’s safety features, you do not exceed the weight limit of the seat, even if the product still appears sturdy enough. Doing so can not only affect how securely your child fits into the seat, but it can also interfere with the handling of the bicycle too.

Types of child bikes seats

As is the case with many infant-focused products such ascar seatsandpushchairs, there are different types of bike seats for kids, this allows you to pick an option which best suits the needs of you and your child.  

The main categories of bike seats are: 

Front-mounted bike seat

  • Attaches to the steerer tube or top tube.
  • Best used for toddlers and children up to five years old.

Rear-mounted cantilevered bike seat

  • Mounted to the bike’s seat tube.
  • Recommended for children aged nine months and over.

Rear seat and stay tube mounted bike seat

  • Attached to both the seat tube and seat stays.
  • Best used for kids aged nine months and older.

Rear rack mounted bike seat

  • Is secured on the top or rear of the bike rack.
  • Suitable for children aged nine months and over.
