How can I choose the best bike for my children?

This chart provides a general idea of the type and wheel sizes of bicycles your children can ride on, based on their age.

The best bike, from your children’s point of view, will be the one that is:

-suitable for their age as one that is too big scares them.

-in the colours that they like.

-printed with images of their favourite cartoons (for the younger ones).

-similar to that their friends are cycling on (for the older kids).

-meet their purpose, example, BMX for kids who enjoy performing tricks or road bike or fixie for those who enjoy speeding down the road on large wheels or MTBs for those who like to cycle on rough terrains.

From different parents’ point of view (I have met many), the best bicycle for their children will be the one:

-that is safest to ride on, which is usually smaller in size than the one recommended by the bike shop
because they are worried that their children cannot handle them and will be hurt.

-that is the cheapest one in the shop because they are frugal or they have a budget to meet.

-that is easy or not costly to maintain, example, with no gear components installed because they do not trust that their children will take care of the bike well.

-that can also be ridden by other members in the family because they are practical or there are too many members in the family to get each child a bike.

-that have more accessories installed like carrier, mudguards, bell and basket.

-that comes with lots of free gifts like helmet, bell and lights.

From a bike shop owner’s point of view, the best bike for children will be one:

-that the child can ride over a longer period of time (but that is bad for my business).

-that can be shared amongst siblings and, if possible, adults in the family (but that is bad for my business).

-that are installed with carrier, basket , mudguards, bell, front and rear light for children who rides to school or run errands on them.

If you are looking in that direction, consider getting adult folding bikes for your children. As you can see, the seat post and stem height on a folding bike are adjustable to cater to riders of various heights.  This also allows the cyclist to sit in a more upright position.

So, an adult folding bike in wheel size of:

-12″ and 14″ can be ridden by a child age 4.

-16″ can be ridden by a child age 5 and above.

-20″ can also be ridden by a child age 6 till adulthood.

Also, the handlebars on some folding bicycles can be removed if they are bolted on to the stems or there is a quick release mechanism to release them from their stems.

If the distance from the seat to the handlebar is too far to reach. it allows the parent to replace the current handlebar to one that is curved towards a shorter rider in the family.

There are adult bicycles in the market with smaller wheel size that their children can also ride on. This is a 16″ wheel size bicycle made for the Japanese market. A child age 5 or above should be able to ride on it.

This is also made for the Japanese market. Its rear wheel is 16″ while the front is 24″.

Some 20″ wheel size bicycles for children can also be ridden by adults. A child age 6 should not have any problem cycling on a 20″ wheel size BMX.  However, if the top tube length is too long, the handlebar can be pushed towards a shorter rider to enable him to reach it.

Just note that getting the child a BMX with a longer top tube length means that he will be able to ride it for a longer period of time.

When the child is taller replace the seat post to one that is laid back.  The increased distance from the saddle to the handlebar will make the child's ride more comfortable.

The carrier on this 20″ wheel size bicycle can handle load as it is welded to the frame. This is a suitable bicycle for a child who rides to school or have to run errands on it.  

Changes can be made to a bicycle to meet the purpose for buying it.  For example, the customer of the above bicycle, opt to attached a removable padded rear seat to the bicycle so that she can ferry her younger sibling. The original saddle was replaced with one that is larger so that seniors in her family can sit on it comfortably. A stem extender was also added to increase the height of the handlebar so that someone taller in the family can ride on it with comfort.

Here is another 20″ wheel size, low cost and low maintenance bicycle to consider getting for children age 6 and adults to ride on.  It looks like a folding bike as its top tube is low. 

If you plan on getting a bicycle for your child to ride to school on, consider getting one with full mudguards installed as it rains all year round in Malaysia. 

Install the training wheels correctly

Bicycle size 12” right up to 16” are installed with training wheels. They are meant for child age 3 to 7. The reason why most kids still need training wheels even after they have outgrown their bicycles is because the training wheels have been installed leveled with the rear wheel.

The training wheels should be installed with a clearance of less than half an inch from the ground. That way, the child will learn to move his weight from left to right and vice versa each time he feels like he is toppling over.

There are training wheels in the market for 20” bicycles and they are adjustable to fit 12″ to 16″ too. Make sure that you get one that comes with metal instead of PVC cap, as shown in this photo.



Any brand of bicycle with no gears can be fitted with training wheels. Just make sure that they are not installed leveled with the rear wheel.

What is the best bike for a child age 5?

If you know the age of the child, you can refer to this "bicycle chart" to determine the right wheel size bicycle to buy.  A 16" wheel size bicycle will be suitable for a child age 5.

Note that if you get the child a 12” bicycle when he should be riding on a 16”, his legs will ache due to fatigue as the saddle is too close to the handlebar for him to ride comfortably. He will often stand on the pedals to cycle to ease the ache. The PVC pedals installed will not be able to withstand his full weight on them. So, if you have to replace the pedals frequently, you will know that the child has outgrown his bicycle or you have bought the wrong size bike. 

Bicycles with wheel size of 12” right up to 16” will have training wheels already installed on them. There are also 12″ bicycle with removable rod attached so you can hold on to the rod while the child learns to ride.

This is very helpful when it is time to remove the training wheels as the child may still need support.  Without the rod, you may have to lean over to hold on to the handlebar and saddle to assist the child.

If you opt for a 12” balance bike you will have to note the age range the model is suitable for. Example, the JDBug models I carry is suitable for children age 2.5 to 5 years and can take a rider’s weight load of up to 30kg. There is also an option to install pedals when these are required at a later stage. So, if you decide to get a balance bike, you will have to study what is suitable for a child age 5.

I noticed that children enjoy choosing bicycles in my shop. They will try to find the kind of bicycles that their friends are cycling. They will be even happier if they can find bicycles in colours of their choice or with cartoon characters they like.

If it is possible, bring the child to a bikeshop.  Let him sit on the bicycle of his choice. Does he feel comfortable on it? Is the bicycle too big and heavy for him? You will know that it is not suitable if he has difficulty pedaling it.

There are a great variety of bicycles for kids in the market. Make sure that the regular bicycle you choose comes with mudguards and a bell attached. The child will be able to sit in a more upright position if you get him a bicycle installed with BMX handlebars like this.

Add front and rear lights if he intends to ride out at night. If it is within your budget, also provide the child with a protector set.

Can an adult ride an 16 or 18" kids bike?

This bicycle has a size 16″ rear wheel and a size 24″ for its front wheel. It is a bicycle suitable even for shorter members in the family.



This is also a 16″ bicycle.


Adults should not look awkward cycling on bicycles like these.

Size 12″ to 20” folding bike is another option a shorter rider can consider. You can raise the seat post and handlebar to a height where you will feel comfortable cycling. Straddle over the body of a 20” folding bike. It is not likely to touch your crotch area.

This is a how a 12 inch wheel size folding bike looks like.



This is a 20″ folding bike.


If the handlebar of a 20″ foldie is too far away for your reach, choose a folding bike that gives you the option to change the handlebar to one that you can reach. Some folding bikes come installed with T shape handlebar which is not interchangeable.

A bicycle with 20" wheelset is suitable for kids 6 years and above. However, if you get yourself a 20″ BMX bike with a top tube length of 18" to 20" you will be able to ride it till you are 5’ 3” in height.



A BMX has higher handlebar which is more comfortable as you do not have to slouch over to reach it. If it is installed too far for your reach, you can lower it down towards you. The seat post bends backward to accommodate the height of taller riders. That way, their legs will not feel too tired cycling. There is a tendency for cyclists to stand on the pedals to ride to relieve the fatigue and that will damaged the pedals sooner.

I usually discourage my customers from buying 18″ wheel size bicycles as it is not a common size in Malaysia and they will have difficulty finding spare tyres and tubes.
