Sharing is caring!

When should I consider mid-mount child bike seats/ MTB?

Mid-mounted (MTB seat) is the right child seat for mountain bike. Your child is placed between you and the handlebar. This way you can maintain your center of balance much easier and challenge the mountain trails.

The mid-mount child bike seat is free from a harness, so your child must hold on. Don’t worry though! It is a great way of biking with a toddler and has a lot of advantages. Your child is located between your arms, and you have got more space for maneuvering. 

The age range starts from 24 months to 5 years and up to 48 lbs (22 kg).

What are the benefits of the child seat for mountain bike?

There are a few good reasons to get mid-mounted child bike seats.

  • Your child is placed lower on the frame as opposed to the front-mounted child bike seat, so the child is more centered and his weight is in line with yours.
  • You have got more balance and control over the ride.
  • MTB child bike seats are simple and straightforward. You don’t need to deal with the bulky child front bike seat instead. Getting on and off is very simple too.


  • A front bike seat for child provides you and your baby with a fantastic interaction throughout the whole trip.
  • You don’t need to yell or intentionally turn your head to the side to hear what your baby is trying to tell you.
  • The child seat for mountain bike is extremely light and can be carried anywhere.
  • You see your child and so able to control their needs. You will know immediately when they want to drink some water, about to take a nap, or lost something on the way.
  • Your child has a great view of everything in front of him.
  • It is a great experience for your toddler indeed.

How to choose the right child seat for mountain bike?

The first step is to decide what you need the mid-mounted toddler bicycle seat for.

  • Recreational/ casual or
  • Mountain-type leisure?

Recreational bike riding with toddlers includes short easy rides in the area. It typically offers an additional handlebar for your baby, such as UrRider child bike seats. Mountain biking requires a special child seat for mountain bike which is different from the front-mounted bike seat.

What is the difference between recreational bike seats for toddlers and mountain child bike seats?

Mountain child bike seats are slimmer and do not offer any additional accessories. They are designed for a mountain ride and to ensure the rider has more space for maneuvering.

All three reviewed below, Do Little, MacRide, and Shotgun bike seats for kids offer a universal mounting system for all mountain-style bikes.

Recreational child bike seats are bulkier and offer some additional features, such as integrated handlebars. But they are not ideal for mountain biking as such.

Note: Mountain child bike seats are suitable for occasional recreational rides, whilst recreational are not suitable for mountain biking.


You should always check the compatibility with the bike brand you have. Additional information is added to each review of the child seat for mountain bike below.

Age of your child

It is important to consider the age and size of your toddler. The main disadvantage of the mid-mounted child bike seats is that they do not provide a harness system, so the child is unstrapped and must hold himself. He also has to stay still during the ride. It may be more challenging for a two-year-old but should be more achievable with a 3- or 4-year-old toddler.

Finally, consider the size of the child. If he is over 4 years of age, he will be bigger and heavier, so it will be more challenging for you to ride the mountain bike.

Rider’s height

The rider’s height also plays a great role. The higher your seat is set up, the easier it is for you to ride. Also, you should maintain some space between your shoulders and the child’s head, so it is comfortable for both of you.


Consider the size of your bike and how comfortable it will be to ride with the child in front. The distance between your handlebars and seat tube should be not less than 20 inches (50 cm).
