8 Steps: How to Set a Child's Bicycle

Do you want your little rider's bike to fit like a glove? It's not just about picking the right bike size: the correct bike setup is as important. It will make the ride comfortable, safe, and much more fun! There will be nothing to stop your little racer from having fun cycling. In today's article, we will point out 8 simple steps on how to adjust a child's bike so that your child can enjoy every adventure in the saddle to the fullest.

Why is Setting up a Child's Bike So Important?

A well-set-up children’s bike is crucial for a safe, comfortable, and healthy ride. If the bike is too big, too small, or set up incorrectly, your little one will have a hard time learning to ride it, get tired more quickly, and be at a higher risk of accidents and injuries. What’s more, incorrect bike set-up often leads to bad movement habits and unnecessary strain on joints and muscles.

On the contrary, a well-set-up children's bike supports proper posture, stability while riding, and helps kids gain confidence, self-esteem, and have fun when riding.

Step 0: Choosing the Right Bike Size

"Okay," you’re probably thinking now, "I get it, having my child's bike set up correctly is important...but where do we start?"

First of all, make sure you have the right bike size. Children's bikes are not sized by frame, but by wheel diameter in inches – from 14" for the smallest riders to 26" or 27.5" for older children and juniors. 

The size of a children's bike should always correspond to your child's height. The determining factor for smaller children is the inseam length. Your little rascal should be able to touch the ground with the tips of their toes comfortably.

How to Set up a Children's Bike

1 Saddle Adjustment: Comfort & Proper Fit

Now you have the right bike size. Hooray! It’s time to set the saddle height. For young cyclists learning to ride their bikes, it is ideal to have their saddles lower so they can reach the ground with their toes. It makes them feel safe when learning to keep balance. 

On the other hand, for more advanced young riders who already have the cycling skills, set the saddle so that your child’s leg is slightly bent when the pedal is in its lowest position. This makes pedalling more efficient and protects knees from overload. If your child visibly sways from side to side while pedalling, the saddle is probably too high.

2 Handlebar Height & Angle

The correct adjustment of the handlebars is no less important. The height of the handlebars of a children's bike should correspond to the natural spine position: the little cyclist should neither lean too forward nor sit too upright. For smaller children, the handlebars are often at a higher level than the saddle. It provides a greater sense of stability and control over the bike.

Also, set the handlebars to the correct angle: the little racer should be able to reach the brake levers without twisting their wrists and rest their arms comfortably.

3 Brake Adjustment: Safety First

Brake time, everyone! Let's focus closely on the key safety element: that’s right, the brakes. RASCAL children's bikes are equipped with hand brakes. It is essential to set the distance and angle of the brake levers correctly so that your little rider reaches them without any problems. The distance of the levers from the handlebars can be easily adjusted using the tiny Allen screws.

Next in concern is the angle of the brake levers. The ideal angle of the brake lever on a children's bike should correspond to the natural position of the child's hand when holding the handlebars. The levers should be angled so that when the fingers are extended towards the brake, the hand, wrist and forearm form a line - no unnatural bending of the wrist up or down!

As for the brakes themselves, they must engage smoothly and continuously - ideally when the lever is pressed halfway. You can adjust the engagement position using the adjustment screw, which is to be found where the brake cable enters the lever.

4 Adjusting the Derailleur

Time to shift to a different topic! Does your children's bike have a derailleur? Here, you need to check whether it changes gears smoothly, without skipping, or the chain falling off.

You tune the derailleur with the adjusting screw located directly on the derailleur. By turning it anticlockwise, you move the derailleur towards the larger sprockets of the cassette and vice versa. A bike with only one gear is more suitable for smaller children: they can fully concentrate on pedalling and controlling the bike without getting distracted by the need to change gears. 

That's why RASCAL children's bikes from the Classic series are equipped with an internal gear hub, which allows for shifting gears even when the bike is stationary - for example, at traffic lights, at the foot of a climb before getting on. A standard derailleur requires movement of the pedals and chain to shift. Shifting is much easier for the little rascals thanks to an internal gear hub, especially at the beginning of their riding career.

5 Ergonomics & Details that Make a Difference

The ergonomics of a children's bike is often underestimated, but this is also important. Why? Imagine riding a bike and not being able to reach the brakes or pedals. Ooof – it's not much, is it? We can probably agree that it would be uncomfortable at least. And the same applies to children, whose bodies are smaller than those of adults.

Brake levers, handlebar grips, saddle, and pedals should fit children's smaller hands and feet. It is advisable to buy non-slip pedals that are wide enough to keep the child's feet from slipping when racing the wind. The appropriate length of the cranks, the width of the handlebars, the number and range of gears all play an important role in comfort and safety.

And here is the best thing: the RASCAL children's bikes have all these details. Each RASCAL bike model is equipped with components tailored for children.

6 Mandatory Equipment & Safety Features

Clink, clink – law and order here! Just as every car, every bike must have mandatory equipment. This includes a white reflector at the front, a red reflector at the rear, and orange reflectors on the pedals and in the spokes of wheels. Of course, a stylish, functional bell and good-quality lights come in handy when the sun is playing hide and seek.

And don't forget the most essential safety equipment of all: a bicycle helmet. Children often tend to copycat their parents. So, be a responsible role model for young cyclists and put your bike helmet on as well!

7 Psychology of a Young Cyclist

Not only bikes need a setup! It's also about the psychological setting of the little rider. They are both closely connected! If your little rider feels that they have their bike fully under control, they will gain much more confidence, self-determination and a desire to learn new skills. The first rides should therefore take place in a safe place without traffic and obstacles, ideally in a park or on a playground.

8 Keep the Bike Maintained & Serviced

Last but not least – don't forget to take regular care of your child's bike. The right bike set-up is essential, but ongoing maintenance is just as important. Every parent knows that children's bikes often get a real beating – they drag their bike through rain, mud, puddles, grass, and tune the frame with a few stylish scratches. Okay, maybe there will be more than a few at the end of the day.

Therefore, for your little rider’s safety, regularly check not only the tightness of the bolts and functionality of brakes, but also the condition of the chain and tires. The tires should be properly inflated; the chain should be clean and lubricated. Don't forget about brake pads, which gradually wear out, and reflectors or lights, which can become loose or damaged.

Ideally, before the start of every season, or before every longer trip, we recommend having your bike "examined" by experts at a bike repair shop. And believe us, it's worth it: regular bike care will not only extend its lifespan, but most importantly, it will ensure that your little cyclist will ride safely and happily.
